Nutrients Involved in Skin
Last updated: August 9, 2026
5 nutrients Tavita's library ties to skin, framed as support for normal function — never as a treatment, prevention, or cure.
This grouping is Tavita's own editorial reading of NIH Office of Dietary Supplements fact sheets — it isn't a transcription of a single published table. The established or emerging label next to each nutrient reflects the strength of the evidence behind it, not a guarantee of an effect for you. See the methodology page for how the library is built and verified.
This is educational information, not medical advice. Talk to your clinician before changing your supplement routine, especially if you take medication or manage a condition.
How to read the evidence tier
Human trials support this nutrient moving this system for a typical person, not just a lab or animal mechanism.
A plausible mechanism with mixed, preliminary, or limited-population evidence — often shown mainly in people who were already deficient.
Nutrients involved in skin
Omega-3 EPA Emerging
Skin is your body's largest organ and it rebuilds itself constantly. These nutrients support the collagen-making and repair work that keeps skin looking clear and feeling calm.
Vitamin A Established
Skin is your body's largest organ and it rebuilds itself constantly. These nutrients support the collagen-making and repair work that keeps skin looking clear and feeling calm.
Caution: Preformed vitamin A (retinol, from liver and supplements) builds up in the body. Very high intakes strain the liver, and during pregnancy they can harm a developing baby — if you're pregnant or might become, keep retinol supplements modest and check with your clinician. Beta-carotene from plants doesn't carry the same risk.
Vitamin C Established
Skin is your body's largest organ and it rebuilds itself constantly. These nutrients support the collagen-making and repair work that keeps skin looking clear and feeling calm.
Vitamin E Emerging
Skin is your body's largest organ and it rebuilds itself constantly. These nutrients support the collagen-making and repair work that keeps skin looking clear and feeling calm.
Zinc Established
Skin is your body's largest organ and it rebuilds itself constantly. These nutrients support the collagen-making and repair work that keeps skin looking clear and feeling calm.
