Water vs. Electrolytes: Which Is Better for Hydration?

The hydration aisle can make a simple glass of water feel strangely incomplete. Bottles, powders, tablets, and stick packs promise added minerals, faster hydration, or better recovery, while plain water remains inexpensive, familiar, and free of calories. The confusing part is that both sides of the comparison contain some truth. Your body always needs water, but it also relies on charged minerals to manage fluid balance, nerves, muscles, and normal cellular activity. The better choice therefore depends less on marketing language and more on what your body has actually lost.

For most healthy adults on ordinary days, plain water and a balanced diet are enough. An electrolyte drink becomes more useful when fluid loss also carries mineral loss, such as during prolonged exercise, heavy sweating, heat, vomiting, or diarrhea. Electrolytes do not replace water; they are dissolved in fluid and help the body manage it. The right option depends on activity, climate, diet, health, and the drink’s formula.

Picture two people reaching for the same electrolyte packet. One has spent the day at a desk and eaten regular meals. The other has cycled for two hours in humid weather, leaving salt marks on a jersey. Their bottles may look identical, but their needs are not. Understanding that difference turns hydration from a trend into a practical decision you can make repeatedly, whether you are at work, on a flight, in the gym, or recovering at home.

What Is the Difference Between Water and Electrolytes?

Water provides the fluid your body needs, while electrolytes are charged minerals that help regulate where that fluid moves and how cells function. Sodium, potassium, chloride, magnesium, calcium, phosphate, and bicarbonate support fluid balance, nerve signaling, muscle activity, heart rhythm, and acid-base balance. The practical comparison is plain water versus water containing added electrolytes. They work together rather than competing as separate hydration systems.

What Does Water Do?

Water is the basic medium for circulation, digestion, temperature control, nutrient transport, and waste removal. It helps maintain blood volume, keeps tissues lubricated, and allows the body to release heat through sweat. Electrolytes cannot perform those jobs without fluid; they must first dissolve in water before they can move through the digestive tract and body fluids. An electrolyte packet is therefore an addition to water, not an alternative to it.

The body loses water continuously through urine, breathing, the skin, and bowel movements. Those losses increase during exercise, hot weather, fever, vomiting, diarrhea, high altitude, and some medication use. For an ordinary day, the kidneys and thirst response usually manage small changes well. Drinking regularly with meals and responding to thirst is more useful than forcing large amounts at once.

Urine color can provide a rough clue, but it should not be treated as a perfect hydration test. Foods, B vitamins, medicines, and the time of day can change urine appearance. Pale yellow urine often fits normal hydration, while completely clear urine all day may simply mean fluid intake is higher than necessary. Persistent dizziness, confusion, fainting, very low urine output, or inability to keep fluids down requires medical attention rather than another flavored drink.

What Do Electrolytes Do?

Electrolytes are not one substance. They are a group of minerals with different physiological roles, and the body maintains them within controlled ranges. Sodium and chloride are major components of fluid outside cells. Potassium is concentrated mainly inside cells. Magnesium and calcium participate in nerve transmission, muscle contraction, enzyme activity, and other essential processes. Bicarbonate and phosphate also contribute to normal acid-base balance.

This is why the phrase “contains electrolytes” tells only part of the story. A product may include five minerals but provide only tiny amounts of each. Another may focus mainly on sodium because it is intended for sweat replacement. A third may add vitamins, collagen, creatine, amino acids, or caffeine, changing the product’s purpose beyond basic hydration. The disclosed amounts determine its practical relevance.

Electrolytes come from normal foods as well as drinks. Salt supplies sodium and chloride; potatoes, beans, yogurt, fruit, and vegetables provide potassium; nuts, seeds, legumes, and whole grains contribute magnesium; and dairy foods or fortified alternatives can supply calcium. For many healthy people eating regular meals, the diet already provides enough electrolytes for everyday activity. Supplemental electrolytes become more relevant when losses rise or access to food is limited.

Are Hydration Drinks the Same?

Electrolyte water, sports drinks, powder sticks, and oral rehydration solutions may look similar in a bottle, but their formulas and intended uses can be very different. Mineral water may contain naturally occurring calcium or magnesium. Electrolyte-enhanced water may contain only trace minerals for taste. Sports drinks often combine sodium and carbohydrate for longer activity, while powder sticks range from simple mineral blends to multi-ingredient performance formulas.

Beverage type	Main purpose	Common formula features	What to verify
Plain water	Everyday fluid replacement	No calories or added actives	Personal fluid needs and water quality
Electrolyte water	Light mineral addition	Small amounts of sodium, potassium, or magnesium	Actual milligrams, not front-label wording
Electrolyte powder	Portable hydration support	Minerals, flavors, sweeteners, and sometimes added nutrients	Serving size, sodium, sugar, caffeine, and active ingredients
Sports drink	Fluid plus exercise fuel	Electrolytes and carbohydrate	Sugar, calories, sodium, and intended exercise duration
Oral rehydration solution	Rehydration during specific fluid-loss situations	Defined glucose-electrolyte balance	Directions, age suitability, and medical context

A zero-sugar electrolyte water is not automatically suitable for endurance fueling, and a sweet sports drink may add little value during a quiet workday. Most importantly, an ordinary wellness beverage should not be presented as interchangeable with a medically appropriate oral rehydration solution. Read the purpose, formula, and directions—not only the category name—before confidently choosing a serving for your routine.

Which Hydrates Better: Water or Electrolytes?

Neither hydrates better in every situation. Plain water works well when fluid losses are modest and normal meals replace minerals. An appropriately formulated electrolyte drink may support better fluid retention after substantial sweating or other meaningful fluid loss. Its advantage depends on mineral amounts, carbohydrate content, total fluid intake, and the person’s actual needs—not simply the word “electrolytes.” Context determines the better choice.

How Does Sodium Help?

Sodium plays a central role in extracellular fluid balance. When sodium is present in the intestine, it supports water absorption; after meaningful sweat loss, replacing some sodium can also help the body retain the fluid consumed. This is particularly relevant during long exercise, repeated training, outdoor work, or other situations in which water and salt are lost together. Sodium also influences thirst and urine output.

The effect is situational. Someone completing a 30-minute indoor strength session may lose little sodium and can usually recover with water and a normal meal. Someone cycling for two hours in humid weather may finish with soaked clothing and visible salt marks, suggesting a very different replacement need. Even then, the ideal sodium amount varies because sweat rate and sweat sodium concentration differ considerably between people.

Food matters too. A post-workout meal containing soup, bread, cheese, eggs, or other salted foods may supply sodium alongside carbohydrate and protein. An electrolyte drink can be convenient when food is not available, appetite is low, or another session is approaching, but it is not the only recovery route. Consumers following sodium restrictions or managing health conditions affected by fluid balance should not copy an endurance athlete’s formula without professional guidance.

Do Electrolytes Work Faster?

The claim that electrolytes “hydrate faster” needs context. Sodium and glucose can support water transport across the intestinal wall, and drinks containing electrolytes may improve fluid retention after dehydration. However, absorption speed, fluid retention, and overall hydration status are not identical measurements. A drink that produces less urine over several hours is not necessarily required for someone who began the day normally hydrated.

Hydration studies may measure urine output, net fluid balance, blood markers, body-mass recovery, exercise performance, or perceived thirst. Different endpoints can produce different conclusions. Beverage hydration research shows that composition can affect short-term fluid retention, but it does not prove that every commercial electrolyte drink is superior to water. Mineral concentration, carbohydrate, protein, calories, taste, and the volume consumed can all influence the result.

Practical behavior often matters more than a small laboratory difference. A lightly flavored drink may encourage someone to drink enough during a hot shift, while an overly sweet or salty product may reduce intake or cause stomach discomfort. The useful question is therefore not only how quickly a beverage is absorbed, but whether its formula, taste, and serving instructions help the person replace the fluid and minerals actually lost.

Can More Be Worse?

More electrolytes do not guarantee better hydration. The body regulates sodium, potassium, and other minerals within relatively narrow ranges. Healthy kidneys manage normal dietary variation, but concentrated formulas, repeated servings, medications, and underlying conditions can change the picture. A high-sodium product designed for prolonged heavy sweating may be unnecessary for someone sitting at a desk and eating a sodium-rich diet.

Stacking is a common oversight. A person may use an electrolyte packet, drink a sports beverage, eat salty snacks, and take a magnesium supplement on the same day without considering the combined intake. The FDA Daily Value for sodium is 2,300 mg, which is useful for reading labels but is not a personalized sweat-replacement target. Daily Values describe how a serving fits into a general diet; they do not calculate what one athlete lost during one workout.

Overdrinking also deserves attention. Consuming fluid far beyond losses can dilute blood sodium, and adding a small amount of electrolytes does not make unlimited drinking safe. Symptoms such as confusion, severe headache, repeated vomiting, fainting, marked weakness, or worsening swelling should not be managed by guessing at mineral doses. Suspected electrolyte imbalance requires clinical evaluation and may require blood testing.

When Is Water Enough?

Water is generally enough for everyday hydration, light activity, and many workouts lasting less than about one hour when meals are regular and conditions are comfortable. That time point is only a practical guide. Workout intensity, sweat rate, heat, humidity, clothing, body size, and individual health can make a shorter session demanding or a longer easy session relatively low-loss. Your real losses matter more than the clock.

Is Water Enough Daily?

For most healthy adults in a temperate environment, plain water should remain the default drink. The National Academies’ Adequate Intake for total water is about 3.7 liters per day for adult men and 2.7 liters for adult women. These figures include water from food and every beverage, not only plain drinking water. In the intake data used to establish those references, food supplied roughly 19% of total water.

Daily reference	Adult men	Adult women	How to interpret it
Total water Adequate Intake	3.7 L	2.7 L	Includes drinking water, other beverages, and food moisture
Approximate beverage contribution	3.0 L	2.2 L	Population reference, not a mandatory personal target
Approximate food contribution	0.7 L	0.5 L	Changes with fruit, vegetables, soups, dairy, and other foods

These values are not universal prescriptions. Pregnancy, breastfeeding, high activity, heat, altitude, illness, medications, and body size can raise or alter fluid needs. A smaller sedentary adult and a large outdoor worker should not be expected to drink identical amounts. Regular access to water, drinking with meals, and attention to thirst usually create a more sustainable routine than forcing a rigid gallon target.

Is Water Enough for Exercise?

Water is usually a sensible first choice for short or moderate exercise when you start normally hydrated, the environment is cool, and sweating is limited. A light walk, yoga class, casual bike ride, or 30–45-minute gym session rarely requires a specialized hydration formula. The next regular meal can replace modest mineral losses while water replaces the fluid component and normal recovery is expected.

Duration should not be used alone. A hard 45-minute run in humid weather may cause more fluid loss than a relaxed 90-minute walk on a cool day. When a more precise estimate is useful, compare body mass immediately before and after exercise. One kilogram of body-mass change is approximately equal to one liter of net fluid change, after adjusting for drinks consumed and urine produced.

For example, a person who weighs 70.0 kg before training and 69.2 kg afterward has lost 0.8 kg. If that person drank 0.5 liters during a 90-minute session and produced no urine, estimated sweat loss is about 1.3 liters, or approximately 0.87 liters per hour. Repeating this check under different conditions provides more useful information than copying another person’s bottle plan.

Do Meals Replace Electrolytes?

Normal meals replace electrolytes more effectively than many people realize. Sodium and chloride are common in salted and prepared foods. Potassium is found in potatoes, beans, lentils, yogurt, bananas, citrus fruit, and leafy vegetables. Nuts, seeds, whole grains, and legumes supply magnesium, while dairy foods and fortified alternatives can contribute calcium. Food also delivers carbohydrate, protein, and other nutrients that a hydration drink does not replace.

This is why plain water plus a meal can be a complete recovery strategy after routine activity. A bowl containing rice or potatoes, vegetables, a protein source, and normal seasoning supplies fluid-supporting minerals alongside energy and amino acids. An electrolyte powder is useful when portability, appetite, timing, or heavy losses make food less practical, not because food-based electrolytes are inferior.

The diet should also be considered when reading product labels. Someone eating restaurant meals and packaged snacks may already consume substantial sodium, while someone eating mostly minimally processed foods may consume less. A formula should be matched to the full day rather than assessed in isolation. The number of minerals listed on the front label matters less than their disclosed amounts and the user’s actual nutritional pattern.

When Do You Need Electrolytes?

Electrolytes become more relevant when water and minerals are lost together in meaningful amounts. Typical situations include prolonged or intense exercise, repeated training, several hours of sweating, strenuous work in heat, or vomiting and diarrhea. The appropriate product depends on the cause and severity: an exercise drink and a medically formulated oral rehydration solution are not interchangeable. Match the response to the cause, not merely the symptoms.

After Long Exercise

Electrolytes are more likely to be useful when exercise is long, intense, repeated, or produces heavy, salty sweating. Sessions lasting beyond roughly 60 minutes are often used as a practical starting point, but there is no universal switch at minute 61. Temperature, humidity, pace, clothing, fitness, acclimatization, body size, and access to food can all change the need. Replace a demonstrated loss rather than following a trend.

Look for evidence of meaningful loss rather than assuming every workout requires supplementation. Soaked clothing, salt crust on the skin, a substantial post-exercise body-mass change, persistent thirst, multiple sessions in one day, or limited recovery time can all make a portable electrolyte drink more useful. Conversely, light sweating during a short indoor workout rarely demands an aggressive sodium formula before relying on supplementation alone.

Recovery can involve both drinks and food. Water plus a regular meal may be enough when another hard effort is not imminent. A powder stick can simplify hydration when food is unavailable, appetite is reduced, or a premeasured serving is easier to carry. Endurance athletes should test their plan during training rather than introducing a new concentration, sweetener, or multi-ingredient formula on event day.

During Heat and Sweating

Heat raises fluid needs because sweating is the body’s main cooling mechanism. Humidity makes the situation harder because sweat evaporates less efficiently, so a person may continue losing fluid without receiving the same cooling benefit. The CDC’s workplace guidance recommends approximately 8 ounces of water every 15–20 minutes for moderate activity in heat lasting less than two hours. When sweating continues for several hours, a balanced electrolyte beverage may be appropriate.

That guidance should not be separated from other heat controls. Cool water must be accessible, work or exercise intensity may need to be reduced, and breaks should occur in shade, ventilation, or air conditioning whenever possible. People who are not acclimatized should increase exposure gradually. Alcohol can increase risk, and very sugary or highly caffeinated drinks may be poor choices when consumed repeatedly in hot conditions.

Electrolytes cannot make unsafe heat exposure safe. Anyone who feels faint, confused, unusually weak, severely nauseated, or unable to cool down should stop activity and seek appropriate help. Early action is more important than finishing a planned session. People with heart, kidney, blood-pressure, or fluid-balance concerns need individualized guidance because both dehydration and excessive fluid or sodium intake may be harmful.

During Vomiting or Diarrhea

Vomiting and diarrhea can cause the loss of water, sodium, chloride, and potassium while making normal eating and drinking difficult. In this setting, “electrolyte drink” is too broad a category. Oral rehydration solutions use a defined glucose-electrolyte balance intended to support intestinal absorption during diarrheal fluid loss. Sports drinks and general wellness powders may contain very different concentrations and should not automatically be substituted.

Small, frequent sips may be easier to tolerate than drinking a large amount at once, but the directions on the selected oral rehydration product should be followed. Infants, young children, older adults, pregnant people, and anyone with a significant medical condition need additional caution. A consumer supplement should never be positioned as a treatment for severe dehydration or as a replacement for appropriate clinical care.

Warning signs include confusion, fainting, severe weakness, blood in stool or vomit, very low urine output, rapidly worsening symptoms, or an inability to keep fluids down. These signs can indicate a problem beyond routine home hydration. Severe dehydration may require professional treatment, including intravenous fluids. AirVigor electrolyte products are intended for everyday, active-day, and exercise-related nutrition routines; they are not medical oral rehydration therapies.

When Water Feels Insufficient

Feeling thirsty, tired, headachy, or crampy after drinking water does not prove an electrolyte deficiency. Those symptoms may also relate to inadequate total fluid, heat, poor sleep, missed meals, low energy intake, alcohol, medication effects, illness, or training load. Muscle cramps in particular have multiple possible contributors and should not be used as a stand-alone reason to consume increasingly concentrated sodium or magnesium products.

Start by reviewing the context. Consider how long you were active, how much you sweated, whether you ate normally, what the weather was like, and whether symptoms improve with rest, cooling, food, and reasonable fluid intake. If a pattern repeatedly appears after similar high-loss situations, a measured electrolyte strategy may be worth discussing with a sports dietitian or healthcare professional.

Persistent symptoms deserve more than self-diagnosis. Electrolyte levels are assessed clinically with blood tests, and both low and high levels can cause problems. A powder cannot determine which mineral, if any, is out of range. Repeated guessing can delay appropriate care. When symptoms are severe, recurrent, or unrelated to an obvious exercise or heat exposure, professional evaluation is the safer next step.

How Should You Choose Between Water and Electrolytes?

Choose according to the situation first and the product second. Use water for ordinary hydration, then consider electrolytes when sweating, prolonged activity, heat, portability, or limited food access creates a clear need. Compare sodium, potassium, magnesium, calcium, chloride, sugar, caffeine, serving size, and added active ingredients rather than choosing by flavor or mineral count alone. The label should confirm that match clearly.

Which Minerals Matter?

For sweat-related hydration, sodium usually deserves the first look because it is the main electrolyte lost in sweat and plays a direct role in extracellular fluid balance. Chloride commonly accompanies sodium. Potassium, magnesium, and calcium remain important nutrients, but larger amounts of all three do not automatically create a better hydration formula. Their relevance depends on diet, intended use, serving frequency, and tolerance.

Label item	U.S. FDA Daily Value	Hydration relevance	Practical label question
Sodium	2,300 mg	Central to sweat-related fluid replacement	Does the amount match light, moderate, or heavy loss?
Potassium	4,700 mg	Supports normal cellular, muscle, and nerve function	How much comes from food and other supplements?
Magnesium	420 mg	Supports normal nerve, muscle, and metabolic function	Is the amount appropriate, and is it well tolerated?
Calcium	1,300 mg	Supports normal muscle signaling and bone health	Does it serve the drink’s primary purpose?
Chloride	2,300 mg	Works with sodium in fluid balance	Is the amount disclosed clearly?

Daily Values are general labeling references rather than targets for a single drink or personalized sweat-replacement prescriptions. They help consumers compare servings within the broader context of a complete diet. A product can be useful without supplying a high percentage of every mineral. Transparent milligram amounts are more informative than a proprietary blend or a long list with no meaningful quantities.

How Do Sodium and Sugar Matter?

Sodium should fit the expected loss. A lower-sodium formula may be reasonable for an active day, travel, or light sweating, while a more sodium-focused option may make sense after sustained heavy sweating. The FDA considers 5% Daily Value or less per serving low and 20% or more high. Those categories describe contribution to the daily diet; they do not determine the perfect amount for a particular workout.

Sugar also needs context. Carbohydrate can support sodium and water absorption and provide fuel during prolonged exercise. A 6% carbohydrate drink contains about 6 grams per 100 milliliters, or roughly 21 grams in 12 fluid ounces. That may be useful during a long event but unnecessary for someone drinking the product at a desk. Sugar-free options reduce added carbohydrate, although sweetener type, flavor, and digestive tolerance still matter.

Check caffeine and other active ingredients separately. A formula containing guarana, creatine, amino acids, collagen, or vitamins serves a broader purpose than a simple electrolyte drink. Those additions may fit a specific routine, but they should not be mistaken for proof of superior hydration. The complete formula—and not the largest word on the front label—defines how the product should be used.

Can You Use Them Daily?

Some healthy adults can use an appropriately formulated electrolyte drink every day, but daily use is not automatically necessary or an everyday requirement. A recurring need may exist for people who train frequently, sweat heavily, work outdoors, travel often, or find that a portable flavored drink helps them maintain fluid intake. Even then, plain water should remain an important part of the routine.

Count the whole day. Sodium and minerals can come from meals, electrolyte packets, sports drinks, fortified foods, and separate supplements. Multiple servings may turn a moderate formula into a substantial daily intake. Follow the product’s serving directions rather than treating an electrolyte powder as unlimited water flavoring. People with kidney, heart, or blood-pressure conditions, anyone taking medicines that affect fluids or electrolytes, and those who are pregnant or breastfeeding should seek qualified advice before establishing daily use.

Daily routines should also be reassessed when circumstances change. A formula that fits summer outdoor training may be unnecessary during a low-activity week indoors. Likewise, a light daily hydration product may not provide the same sodium or carbohydrate strategy needed for an endurance event. Season, schedule, and training volume all matter. Consistency is helpful only when the product continues to match the job.

How Do You Match the Formula?

Begin with one clear question: what problem is the drink expected to solve? If the answer is ordinary thirst, choose water. If it is light active-day hydration, look for a moderate formula with transparent mineral amounts and a taste you can use comfortably. If it is prolonged exercise or heavy sweat, consider sodium, carbohydrate needs, serving frequency, and personal sweat data. If illness is involved, use an appropriate oral rehydration product or medical guidance rather than a general wellness powder.

AirVigor’s hydration range reflects this scenario-based approach. Its Collagen Hydration formulas combine 10 grams of collagen with 200 mg sodium and 370 mg potassium per stick, serving a hydration-plus-collagen routine. Performance Hydration formulas pair electrolytes with ingredients such as creatine and taurine, which places them in a different category from basic daily hydration. Added ingredients can make a product more convenient for the intended routine without making it necessary for everyone.

Always check the current Supplement Facts, allergens, serving directions, sugar, sweeteners, caffeine-related information, and warnings for the specific flavor and formula on every new package before use. A well-chosen electrolyte product should make the routine clearer and easier. It should not encourage the consumer to ignore water, meals, individual health needs, or the difference between everyday hydration and medical rehydration.

A Practical Bottom Line

Water and electrolytes work together, but they answer different parts of the hydration problem. Water is the everyday foundation because it replaces fluid simply and efficiently. Electrolytes become more valuable when sweating, prolonged activity, heat, or other fluid loss also removes minerals. A thoughtful choice begins with your actual situation, meals, environment, and activity—not with the loudest claim on the package or the longest ingredient list.

For most days, drink water, eat regular nutrient-dense meals, and let thirst guide normal adjustments. For demanding days, compare the product’s sodium, other minerals, sugar, caffeine, and serving size with your expected losses and goals. AirVigor’s clearly labeled, portable hydration formulas are designed to make purposeful routines easier while preserving the most important principle: the formula should fit the person and the moment. When symptoms are severe, persistent, or connected to illness or a medical condition, professional care matters more than any wellness drink.

Frequently Asked Questions

Is Water Better Than Electrolytes for Daily Hydration?

For most healthy adults following an ordinary routine, plain water is the better default because it replaces fluid without adding sodium, sugar, calories, caffeine, or other active ingredients. Regular meals generally replace the electrolytes lost through normal daily activity. An electrolyte drink may be useful when heat, prolonged exercise, heavy sweating, travel, poor appetite, or limited food access changes the situation, but it does not need to replace water throughout the day.

How Do I Know If I Need Electrolytes?

Consider electrolytes when you have a clear reason to expect meaningful mineral loss: a long or intense workout, several hours in heat, repeated exercise sessions, soaked clothing, visible salt marks, or a substantial body-mass change after activity. Thirst, fatigue, headache, or cramps alone do not confirm an electrolyte deficiency. Review fluid intake, meals, weather, sleep, and training load, and seek medical advice for symptoms that are severe, persistent, or unexplained.

Should I Drink Electrolytes Before or After a Workout?

Timing depends on the session and your starting condition. Before exercise, water and a normal meal are often sufficient; electrolytes may help when you begin in heat, expect prolonged heavy sweating, or have little opportunity to eat. During longer sessions, fluid and sodium can support ongoing replacement. After exercise, water plus food may cover modest losses, while an electrolyte drink can be convenient when losses were substantial or recovery time is short.

Can I Drink Electrolyte Water Every Day?

Many healthy adults can use a properly labeled electrolyte drink daily, but routine use is not automatically necessary. Check how much sodium and other minerals each serving adds to your total diet, especially if you use more than one packet or combine it with sports drinks and supplements. People with kidney, heart, blood-pressure, or fluid-balance concerns, and those taking medicines that affect electrolytes, should ask a qualified healthcare professional before making daily use a habit.

Do Electrolytes Help After Heavy Sweating?

Electrolytes can be useful after heavy sweating because sweat removes both water and minerals, particularly sodium and chloride. The benefit is most relevant after prolonged exercise, hot outdoor work, repeated training, or other situations that leave clothing soaked or body mass noticeably lower. The appropriate amount varies widely with sweat rate, sweat sodium concentration, food intake, and recovery time, so a transparent label and a measured serving are more useful than the promise of “maximum hydration.”

Can Too Many Electrolytes Be Harmful?

Yes. More is not always better, and excessive intake can be a concern when concentrated products, repeated servings, fortified foods, and separate supplements are combined. Sodium, potassium, and magnesium also interact with certain medical conditions and medications. Drinking fluid far beyond actual losses can be dangerous even when a small amount of electrolytes is added. Follow serving directions, count the entire day’s intake, and seek urgent care for confusion, fainting, severe weakness, repeated vomiting, or worsening swelling.
