Best Vitamins for Skin? Try Collagen and Zinc

Best Vitamins for Skin? Try Collagen and Zinc

The skin is the largest organ in the human body and can tell you a lot about your overall health, especially as you age. That’s why it’s so important to support skin health with vital nutrients it needs to thrive. But what nutrients are the most important? Two stand out: collagen and zinc.

Collagen for Skin Elasticity

Collagen is a protein that is a central structural component of skin and other connective tissues throughout the body that supports skin elasticity.1 With age, skin can become thinner because collagen production declines.2

A 2019 review of 11 different studies found that taking a collagen supplement helped support healthy skin.3 This is consistent with a 2021 randomized placebo-controlled clinical trial that found that marine collagen in particular helped support skin elasticity, hydration, and radiance compared to placebo.4

It’s important to remember that not all collagen forms are equally beneficial for the skin. For general wellness and glowing skin, choose marine collagen because it contains type I and III collagen which are the types associated with a more youthful appearance and the types used in many of the studies. 

Zinc for Skin Health

Zinc is also important to skin health. Zinc is used both topically and orally to help support skin health because it is an essential mineral for cellular function, including skin cells.5 The skin contains the third most zinc in the human body and is necessary for healthy skin function.6 As an added benefit, zinc also helps support muscle health and immune function.6 

Because foods high in zinc include oysters, crab, lobster, meat, fish, and poultry, vegans and vegetarians may have difficulty getting enough zinc from their diet alone.7

Support Healthy Skin with This Key Combo

Collagen and zinc work together to support healthy skin. They are a valuable synergistic combination that is available as a dietary supplement.
