Research Area: Muscle Health

29 ingredients studied for effects on Muscle Health — sorted by research relevance.

Moderate Evidence

GlyNAC (Glycin + NAC)

GlyNAC combines glycine and N-acetylcysteine (NAC) to support glutathione synthesis. Early clinical data in healthy aging contexts are promising but still limited.

Likely safe
Strong Evidence

Calcium

Essential mineral for bones, muscles, and nerves. Meta-analyses show moderate bone effects in deficiency; high-dose supplements carry cardiovascular risks.

Likely safe EFSA ✓
Moderate Evidence

NAC (N-Acetylcysteine)

NAC is a glutathione precursor with established medical use. As a longevity supplement (especially as GlyNAC), early human data is promising but limited.

Likely safe
Strong Evidence

Omega-3 (EPA + DHA)

Omega-3 fatty acids (EPA + DHA) are among the most thoroughly studied supplements. Evidence is strong for triglycerides and high-risk cardiovascular patients; smaller for healthy individuals.

Safe EFSA ✓
Strong Evidence

Vitamin C (Ascorbic Acid)

Vitamin C is essential for collagen synthesis and other normal body functions, with approved EFSA claims. Megadoses show no clear benefit beyond adequate intake.

Likely safe EFSA ✓
Moderate Evidence

Taurin

Taurine is an amino acid with a central role in energy metabolism. Animal and observational data have sparked aging research interest; robust human evidence is far more limited.

Likely safe
Strong Evidence

Vitamin D3 + K2

Low vitamin D levels are common in northern climates. Supplementation is comparatively well studied in deficiency; K2 is often combined but has weaker standalone evidence.

Safe EFSA ✓
Weak Evidence

Apigenin

Apigenin is a flavonoid from chamomile and parsley that inhibits CD38, an enzyme that degrades NAD+. Complements NMN/NR approaches. Early human evidence.

Likely safe
Moderate Evidence

Ashwagandha (Withania somnifera)

Ashwagandha is an Ayurvedic adaptogen backed by multiple RCTs for stress and cortisol reduction. Sleep and testosterone effects are promising but come from small studies.

Likely safe
Strong Evidence

Beta-Alanin

Beta-alanine elevates muscle carnosine and improves high-intensity exercise performance in 60–240-second efforts; it's a sports tool, not a longevity supplement.

Likely safe
Moderate Evidence

L-Citrullin

L-citrulline may boost nitric oxide production and is linked in studies to improved blood flow and endurance performance during physical exertion.

Likely safe
Strong Evidence

Iron

Essential for oxygen transport, energy metabolism, and immune function. Clearly effective when deficiency is confirmed — do not supplement without a lab diagnosis.

Caution EFSA ✓
Moderate Evidence

Glycin

Glycine is the smallest amino acid, required for glutathione, collagen, and creatine. In GlyNAC form, it shows promise for aging markers in older adults.

Safe
Strong Evidence

Caffeine

The world's most widely consumed psychoactive substance. Hundreds of RCTs confirm effects on alertness, reaction time, endurance, and short-term cognition.

Likely safe
Strong Evidence

Kalium

Potassium is essential for blood pressure, nerves and muscles. Often more important via diet than supplementation—and potentially risky when overdosed.

Caution EFSA ✓
Strong Evidence

Zinc

Zinc is involved in hundreds of enzymes and is essential for immune function, DNA repair, and hormone synthesis. Low intake is not uncommon in older adults and vegans.

Likely safe EFSA ✓
Strong Evidence

Creatine (Creatine Monohydrate)

Creatine is one of the most thoroughly studied supplements for high-intensity muscular work. The strongest evidence is from strength and power sports; further applications are still being explored.

Likely safe EFSA ✓
Strong Evidence

Magnesium

Magnesium is involved in over 300 enzymatic reactions. Low intake is common. The form significantly affects bioavailability and tolerability.

Safe EFSA ✓
Moderate Evidence

Kollagen

Collagen is one of the most popular supplements. Human trials support benefits for skin elasticity and joint markers; broader anti-aging claims remain unproven.

Safe
Moderate Evidence

L-Theanine

L-theanine promotes relaxed alertness via alpha-wave activation. Best evidence for caffeine synergy; moderate effects on stress markers. Alone, cognitive benefits are limited.

Likely safe
Strong Evidence

Vitamin D3

Vitamin D3 is well supported for bone, muscle, and immune function when deficiency is confirmed. Without deficiency, additional benefit is significantly weaker — not a universal upgrade.

Likely safe EFSA ✓
Moderate Evidence

NMN (Nicotinamide Mononucleotide)

NMN is a direct precursor to NAD+. Animal studies are promising — robust human trials are still lacking, and the EU regulatory status is unclear.

Likely safe
Moderate Evidence

Betain (Trimethylglycin)

Betaine is a natural methyl donor that lowers homocysteine and shows modest strength gains in some studies, but evidence is inconsistent and limited.

Likely safe
Strong Evidence

Vitamin A

Essential for vision, skin, and immune function. Clearly useful for deficiency, but high doses are toxic—especially in pregnancy.

Caution EFSA ✓
Moderate Evidence

Urolithin A

Urolithin A is a gut microbiome metabolite from pomegranate polyphenols, emerging in aging research as a mitophagy inducer.

Likely safe
Weak Evidence

MSM

MSM is marketed mainly for joint health and inflammation. The data aren't empty, but significantly smaller than most claims suggest.

Likely safe
Moderate Evidence

L-Tyrosin

L-Tyrosin is an amino acid precursor of dopamine, noradrenaline, and adrenaline. Studies show cognitive benefits under acute stress and sleep deprivation.

Likely safe
Weak Evidence

Fucoidan

Fucoidan is a sulfated polysaccharide from brown seaweed with growing evidence for prebiotic gut effects, muscle health, and cardiovascular markers.

Likely safe
Moderate Evidence

L-Glutamine

L-glutamine is the most abundant free amino acid in the body. Clinically well-supported in critical care; evidence for oral supplementation in healthy individuals is more limited.
