Support muscle growth and power. Ranked by evidence strength from 32 supplements backed by peer-reviewed clinical research.
The most researched supplement for strength, power, and cognitive function under stress.
5-15% strength gains
The gold standard protein supplement for muscle building, recovery, and convenient protein intake.
Enhanced muscle protein synthesis
A slow-digesting milk protein ideal for sustained amino acid delivery and overnight muscle recovery.
Reduced muscle breakdown, sustained muscle protein synthesis
Complete essential amino acid blend that maximizes muscle protein synthesis — superior to BCAAs alone.
Enhanced muscle protein synthesis
A powerful combination of L-citrulline and malic acid that enhances exercise performance, reduces fatigue, and improves muscle pumps.
More reps, better pumps, reduced soreness
Southeast Asian herb with evidence for supporting healthy testosterone levels, energy, and stress resilience.
May increase testosterone, especially if low or stressed
Traditional herb with evidence for supporting testosterone, libido, blood sugar control, and lactation.
Modest increase in testosterone and libido
Amino acid that boosts nitric oxide production, improving blood flow, exercise performance, and recovery.
May improve high-rep performance
Often-overlooked trace mineral that supports testosterone, bone health, and cognitive function.
May increase free testosterone, especially if deficient
A traditional herb marketed for testosterone and libido support, though research shows benefits primarily for libido and sexual function rather than testosterone levels.
Enhanced libido and sexual desire
A plant-derived compound structurally similar to insect hormones that may enhance muscle protein synthesis and strength without hormonal side effects.
Enhanced muscle protein synthesis and strength
Leucine metabolite that helps prevent muscle breakdown and supports recovery, especially during caloric restriction or intense training.
Preserves muscle during caloric restriction
Ancient Ayurvedic substance containing fulvic acid and minerals, used for energy, testosterone, and vitality.
May increase testosterone levels
Increases muscle carnosine to buffer acid during high-intensity exercise, extending endurance for 1-4 minute efforts.
More reps at higher intensities
The three essential amino acids (leucine, isoleucine, valine) that support muscle protein synthesis and reduce exercise fatigue.
Muscle protein synthesis support
A powerful flavonoid found in dark chocolate that may enhance muscle growth, endurance, and cardiovascular health by inhibiting myostatin.
Potential myostatin inhibition and enhanced muscle growth
A powerful adaptogen that reduces cortisol, anxiety, and stress while supporting sleep quality and recovery.
Modest strength and muscle gains
A traditional Chinese herb known as 'desert ginseng' that supports energy, hormonal health, and longevity.
Support for healthy testosterone levels
Natural source of L-DOPA that supports dopamine production, mood, motivation, and reproductive health.
May support reproductive hormones
An essential mineral critical for immune function, testosterone, wound healing, and sleep quality.
Testosterone support if deficient
A Nigerian shrub traditionally used for male vitality that has gained popularity for potential testosterone support.
Potential testosterone support (limited evidence)
An amino acid precursor to nitric oxide that supports blood flow, exercise performance, and cardiovascular health.
Improved muscle pump and nutrient delivery
An essential electrolyte mineral critical for blood pressure regulation, muscle function, nerve signaling, and fluid balance.
Proper muscle function and reduced cramps
The 'sunshine vitamin' essential for immune function, mood, bone health, and regulating over 1,000 genes in the body.
Supports muscle protein synthesis and bone mineral density
A highly bioavailable choline source that supports acetylcholine production for focus, memory, and athletic performance.
Possible power output improvement
Peruvian root vegetable traditionally used for energy, libido, and hormonal balance without directly affecting hormone levels.
May improve libido without changing hormone levels
An essential mineral involved in 300+ enzymatic reactions, crucial for sleep, stress, muscle function, and cognitive health.
Supports muscle contraction and ATP production for strength
A versatile neuromodulator derived from arginine that supports mood, neuroprotection, pain management, and nitric oxide regulation.
Improved muscle pumps via NO modulation
Recovery-optimized form of carnitine with evidence for muscle recovery, androgen receptor upregulation, and exercise performance.
Supports recovery from resistance exercise via androgen receptor upregulation
Adrenal hormone precursor that declines with age, supporting hormone balance, energy, and body composition.
Modest anabolic effects via androgen precursor activity
Proven ergogenic aid that buffers lactic acid, extending high-intensity exercise capacity by 1-3%.
Buffering capacity extends high-intensity work sets
Fat-soluble vitamin that directs calcium to bones instead of arteries, supporting cardiovascular and bone health.
Activates osteocalcin for bone mineralization and density
