The world’s most widely recognized “best” supplement categories are those supported by broad scientific consensus and everyday usefulness: electrolytes, protein, creatine, omega-3, multivitamins/minerals, vitamin D, magnesium, probiotics, amino acids (EAA/BCAA), and collagen.

Types of Food Supplements: A Science-Based Guide

Food supplements used to be a “gym thing.” Now they’re everywhere—electrolyte sticks in office drawers, protein tubs in kitchens, creatine next to the coffee machine.

How to Use Creatine:A Complete Guide

Creatine is one of the most researched and widely used supplements in sports nutrition—yet it remains one of the most misunderstood. Some people treat it like a shortcut to muscle gains.

What Is Creatine Good For: A Science-Based Guide

Creatine is good for improving strength, power, and repeated high-intensity performance by increasing the body’s ability to rapidly regenerate ATP (cellular energy). It can support training volume, lean mass gains over time, and faster recovery between hard efforts. Research also suggests potential benefits for brain energy and mental fatigue in certain situations. For most healthy adults, creatine monohydrate is considered safe to take daily at 3–5 grams.
Is Creatine Safe: A Comprehensive and Scientific Guide

Creatine is considered safe for most healthy adults when taken at research-backed doses (typically 3–5 g/day).
