Evidence-based supplements similar to Vitamin C, ranked by shared goals and clinical evidence. Compare any of them head-to-head below.

1
ZincLikely helps
Involved in 300+ enzymatic reactions — supports immune defense, testosterone production, wound healing, and sleep quality.

2
Vitamin D3Probably helps
Hormone-like vitamin that regulates 1,000+ genes — deficiency is widespread and linked to poor immunity, depression, and bone loss.

3
CollagenLikely helps
Hydrolyzed peptides that rebuild skin elasticity, reduce joint pain, and strengthen bone density — results build over 8-12 weeks.

4
L-GlutamineToo few graded studies
Primary fuel for intestinal and immune cells. Best evidence is for sickle cell disease (FDA-approved); gut, immune, and recovery benefits in healthy people are weak or unproven.

5
TaurineToo few graded studies
Concentrated in heart, brain, and muscle — best-supported for cardiovascular and metabolic health, with modest endurance benefits and emerging (mostly animal) longevity data.

6
Vitamin ALimited support
Fat-soluble vitamin that maintains night vision, drives immune cell differentiation, and regulates skin turnover and cellular growth.
7/10/10

7
EAAsToo few graded studies
Complete essential amino acid blend that maximizes muscle protein synthesis — superior to BCAAs alone.
6/10/10
evidence

8
MultivitaminToo few graded studies
Nutritional insurance that fills micronutrient gaps. In the large COSMOS trial, a daily multivitamin improved memory and slowed cognitive decline in older adults — but it did not reduce total cancer, cardiovascular disease, or mortality.
