Buying Guide

Match stimulant level to your tolerance

Check caffeine sources and milligram ranges to choose a product that supports energy without causing jitters or sleep disruption

Prefer electrolytes for long sessions

If you train for an hour or more, electrolyte tablets or mixes help replace sodium, potassium, and magnesium lost through sweat to sustain endurance

Look for amino acids for recovery and endurance

Branched-chain and other amino acids support muscle recovery and can reduce fatigue during prolonged exercise

Consider sugar content and sweetener type

Sugar-free formulations reduce carbohydrate load and tooth decay risk, while sweeteners can affect tolerance and GI comfort

Verify diet compatibility and allergens

Confirm labels for vegan, gluten-free, or other allergen claims to ensure the supplement fits your dietary needs
