A Functional Medicine Doctor’s Guide To The Essential Supplements for Optimal Skin, Hair, And Nail Health

From my years of experience consulting with patients all over the world at my telehealth functional medicine clinic, I know that it’s a struggle to maintain healthy skin, hair, and nails. You want your health to be reflected not just on the inside of your body, but on your outside, too. 

Our skin, hair, and nails are not just superficial adornments; they are windows to our internal health. By nourishing our bodies from within, we can unlock the secrets to a glowing complexion, luscious locks, and strong, beautiful nails. In this article, I'll guide you through the essential supplements that may make a difference for you.

1. Collagen

This is a true beauty powerhouse, as a structural protein that forms the foundation of our skin, hair, and nails. Over time, our natural collagen production declines, leading to signs of aging. To combat this, I recommend incorporating a high-quality collagen supplement into your routine. Not only does collagen support skin elasticity, but it also promotes hair strength and nail resilience.

2. Omega-3 Fatty Acids

These are essential for maintaining skin health and promoting a glossy shine to your hair. Fatty acids also contribute to strong, healthy nails. These fatty acids help to nourish and protect the skin's lipid barrier, which retains moisture and protects against environmental stressors. Additionally, omega-3s have anti-inflammatory properties, which can help reduce redness and irritation in the skin. Incorporate sources of Omega-3s into your diet, such as fatty fish or flax seeds, and consider a high-quality fish oil supplement.

3. Vitamin E

A powerful antioxidant, Vitamin E acts as armor for your skin, protecting it from oxidative stress and free radical damage. These damaging molecules can accelerate the aging process, leading to wrinkles and a dull complexion. By incorporating vitamin E into your skincare routine, either through diet or supplementation, you provide your skin with the tools it needs to maintain its youthful elasticity. Studies suggest Vitamin E supplementation can improve your skin’s texture and reduce the appearance of fine lines. (1)

4. Biotin

Also known as vitamin B7,  biotin is a key player in promoting healthy hair and nails. It supports the keratin infrastructure, the protein that makes up your hair, skin, and nails. Adequate biotin levels contribute to stronger, shinier hair and resilient nails. While biotin is naturally found in foods like eggs and nuts, a targeted supplement can ensure you're getting the optimal amount for your beauty goals. In fact, research indicates that supplementing with biotin can improve both nail thickness and nail splitting. (2)

5. Vitamin A

This vitamin plays a vital role in the renewal of skin cells, contributing to a smoother and more radiant complexion. It supports the production of sebum, the skin's natural oil, preventing dryness and flakiness. Including Vitamin A-rich foods or supplements in your diet can promote skin cell turnover, reducing the appearance of fine lines and wrinkles. 

6. Vitamin C

Did you know that Vitamin C is a collagen booster? Collagen synthesis relies on Vitamin C, making it essential for maintaining skin elasticity and firmness. Additionally, this vitamin is a potent antioxidant that combats free radicals, contributing to a more youthful appearance. Whether obtained from citrus fruits, bell peppers, or supplements, Vitamin C supports your body's collagen production, positively impacting your skin, hair, and nails. Vitamin C supplementation has been linked to increased collagen synthesis and improved skin texture. (3)

7. Zinc

Zinc is an essential mineral that plays a crucial role in skin repair and renewal. It supports the immune system, contributing to a healthier complexion. Zinc is also involved in collagen synthesis, so it’s deeply intertwined with your skin health. Including zinc-rich foods or supplements in your routine can aid in maintaining the integrity of your skin, hair, and nails. According to studies, zinc supplementation can accelerate wound healing and promote skin health. (4)

8. MSM and phytoceramides

These are two of nature’s most formidable ingredients, designed not only to enhance your skin but to support your overall health. That’s why I worked with Agent Nateur to create a curated supplement that contains both, : h o l i ( r a d i a n c e ). The MSM contained in this formula is OptiMSM®, a high-grade antioxidant with clinically proven benefits. 

It plays a crucial role in building keratin and collagen, promoting not just healthier skin but also contributing to the vitality of your hair and nails. Furthermore, OptiMSM® is recognized for its ability to enhance immune function and provide support to joints and muscles.

When paired with a concentrated source of phytoceramides, specifically digalactosyl diglycerides (DGDG), the combination becomes a powerful force in skin restoration. As we age, ceramides, vital for skin health, naturally decline, leading to issues like tightness, dryness, and the formation of wrinkles. Oral ceramides, like those found in holi ( r a d i a n c e ), have been shown in studies to hydrate the skin through the bloodstream, restoring the skin’s water barrier and promoting optimal hydration and plumpness.

The synergy between MSM and phytoceramides has been clinically demonstrated to mitigate signs of aging, significantly enhancing skin firmness, tone, hydration, texture, and addressing concerns such as fine lines, wrinkles, and acne. holi ( r a d i a n c e ) is not just a skincare supplement; it's a revolutionary approach to nurturing your skin at the cellular level.
