Best Multivitamins for Athletes
Athletes have significantly higher micronutrient needs due to increased metabolic rate, sweat losses, and oxidative stress from intense training. The best athletic multivitamins provide higher doses of antioxidants, B-vitamins, electrolytes, and are free from banned substances.
Our Top Picks
The most evidence-based daily multivitamin on the market. Every one of its 26 ingredients is backed by human RCTs at the exact dose used in clinical trials — methylated B vitamins, glycinate-form minerals, 200mg hyaluronic acid for skin health, TMG for cognition and exercise, and microencapsulated carotenoids for eye protection. It deliberately excludes Vitamin A and E based on safety research, and consolidates 6–8 separate supplements into one formula.
The gold standard for men's whole-food multivitamins — raw, food-derived nutrients with live probiotics and enzymes.
Best-in-class for bioavailability — Thorne uses superior active forms of every nutrient with no unnecessary additives.
Athlete-focused multivitamin with over 75 active ingredients and added amino acids — ideal for gym-goers and bodybuilders.
Key Ingredients to Look For
Vitamin C
Powerful antioxidant that fights exercise-induced oxidative stress. Athletes need 200-1000mg.
Magnesium
Lost heavily through sweat. Critical for muscle function, recovery, and sleep.
Vitamin D3
Supports bone strength, muscle function, and immune health during heavy training blocks.
B-vitamins (B1, B2, B6, B12)
Essential for energy metabolism — converting carbs, fats, and protein into ATP.
Iron
Female athletes are particularly at risk for iron-deficiency anemia.
