Supplements for Athletic Performance

Leucine, isoleucine, and valine metabolized directly in muscle tissue — support protein synthesis and reduce exercise fatigue.

Complete protein with high leucine content that maximizes muscle protein synthesis — most researched protein supplement worldwide.

Leucine metabolite with small benefits to muscle mass in clinical and older populations, but meta-analyses show no effect on body composition or strength in trained, healthy adults.

Complete essential amino acid blend that maximizes muscle protein synthesis — superior to BCAAs alone.

Hormone-like vitamin that regulates 1,000+ genes — deficiency is widespread and linked to poor immunity, depression, and bone loss.

Proven ergogenic aid that buffers lactic acid, extending high-intensity exercise capacity by 1-3%.

Dietary nitrates convert to nitric oxide, enhancing oxygen delivery to muscles — a top-5 evidence-based ergogenic aid.

Blocks adenosine receptors to boost alertness, reaction time, and endurance — one of the most proven ergogenic aids.

A traditional fungus marketed for energy and endurance. The honest verdict: those claims rest on small, often-mixed trials — several found no benefit — while the stronger evidence covers adjuvant kidney and COPD use instead.

Proteolytic enzyme from pineapple that aids digestion with food or provides systemic anti-inflammatory and recovery benefits on an empty stomach.

Rate-limiting precursor to glutathione, the body's master antioxidant — supports mood, respiratory health, and liver protection.

A Traditional Chinese Medicine herb. The honest verdict: many meta-analyses suggest adjuvant benefit for diabetic kidney disease and immune markers, but they rest on low-quality Chinese trials of combination formulas, and the headline longevity/telomere claims are thin or animal-only.
