Creatine Monohydrate
strong evidence · 1000+ studies
Most researched sports supplement. Increases phosphocreatine stores for ATP regeneration during high-intensity exercise.Whey Protein
strong evidence · 800+ studies
Fast-digesting complete protein derived from milk. Richest natural source of BCAAs, especially leucine (key mTOR activator).Beta-Alanine
strong evidence · 200+ studies
Increases intramuscular carnosine levels, buffering acid (H+) during high-intensity exercise. Delays neuromuscular fatigue.Caffeine
strong evidence · 1300+ studies
Most consumed psychoactive. Adenosine antagonist. Well-established ergogenic aid across nearly all exercise modalities.Magnesium
strong evidence · 600+ studies
Essential mineral involved in 300+ enzymatic reactions. Critical for muscle function, sleep, energy production. Most people deficient.Vitamin D3
strong evidence · 1000+ studies
Actually a steroid hormone precursor. Critical for calcium absorption, immune function, hormone production. Widespread deficiency (>40% globally).Zinc
strong evidence · 500+ studies
Essential trace mineral for 300+ enzymes. Critical for testosterone, immune function, protein synthesis. Most athletes at risk of deficiency.Omega-3 (Fish Oil)
strong evidence · 800+ studies
EPA and DHA are long-chain omega-3 fatty acids with potent anti-inflammatory, brain health, and cardiovascular benefits.Ashwagandha (KSM-66)
strong evidence · 40+ studies
Ayurvedic adaptogen herb, most researched for cortisol reduction, testosterone support, and stress resilience.Curcumin (Turmeric)
strong evidence · 200+ studies
Polyphenol from turmeric root. Potent anti-inflammatory via NF-κB inhibition. Poor bioavailability — requires piperine or liposomal delivery.Collagen Peptides
moderate evidence · 60+ studies
Hydrolyzed collagen (types I, II, III) for skin, joint, and connective tissue health. Provides glycine, proline, and hydroxyproline — amino acids underrepresented in muscle meat.Boron
moderate evidence · 20+ studies
Trace mineral that significantly impacts testosterone, vitamin D metabolism, and bone health. One of the most underrated supplements for hormonal health.
