What Vitamins and Supplements Are Good for Hair, Skin, and Nails?

Hair, skin, and nails require solid nutrition from protein, essential fats, vitamins, and minerals for strength and integrity. Besides eating nutritious food, supplements offer an easy and convenient way to ensure you’re meeting your daily nutrient needs. Plus, they can help target specific issues with your nails, hair, or skin.

Let’s look at some of the most important and common nutrients found in supplements that support hair, nail, and skin health, including:

  • Biotin
  • Omega-3 fats
  • Zinc
  • Vitamin C
  • Collagen


Biotin is an essential, water-soluble B vitamin necessary for energy metabolism and genetic expression. It’s naturally found in food including eggs, liver, salmon, pork, beef, sunflower seeds, sweet potato, and almonds.

Biotin is essential for amino acid balance; amino acids build the protein structures found in hair, nails, and skin. A biotin deficiency may appear on the skin; deficiency symptoms include rashes, hair loss, and brittle nails.

Hair, skin, and nail formulas, particularly hair formulas, frequently contain biotin in high doses, which helps increase hair strength. Biotin is non-toxic in very high doses; it’s water-soluble, and the body excretes any excess.


The omega-3s include alpha-linolenic acid (ALA) found in flax seeds, walnuts, and chia seeds,  and EPA and DHA from algae and fish. These fatty acids incorporate into the phospholipids that make up our cell membranes and play a role in cell signaling and the anti-inflammatory response.

A deficiency in omega-3 fats can result in rough, scaly skin, dermatitis, and a decline in the skin barrier. Not to mention, these fats are critical for brain, heart, and immune system health.

Consumption of omega-3 fatty acids in the diet and through supplementation have anti-aging benefits and reduce skin inflammation.


Zinc is an essential mineral for protein synthesis and healthy cells found in seafood (especially oysters), red meat, pumpkin seeds, and lentils.

A zinc deficiency impairs growth and affects skin health, resulting in brittle hair, hair loss, and weak nails. Research suggests that supplemental zinc improves blood levels of zinc and nail strength.

Vitamin C

Vitamin C is an essential vitamin concentrated in the skin to provide antioxidant protection. Strawberries, citrus, bell peppers, broccoli, kiwi, and other produce contain vitamin C.

Using vitamin C supplements and topical serums is another way to increase vitamin C in the skin for benefits, including:

  • Increased collagen production
  • Antioxidant protection from sun damage and pollution
  • Improved barrier function
  • Decreased hyperpigmentation (age spots)

Vitamin C supports skin hydration, evens skin tone, and reduces signs of aging, such as fine lines.

Vitamin E

Vitamin E is another antioxidant found in the skin, which is lower in people with skin diseases, such as psoriasis and acne. Vitamin E is found in nuts, seeds, and other dietary sources, as well as multivitamins, supplements, and topical hair and skin treatments. Some evidence suggests that vitamin E increases hair count.


Collagen is the most abundant protein in the body, concentrated in connective tissues, bone, skin, hair, and nails. (Keratin is another vital protein in hair, skin, and nails you may find in supplements).  

Collagen production declines with age, leading to:

  • Decreased skin elasticity
  • Decreased skin thickness
  • Increased wrinkles and fine lines
  • Decreased skin hydration
  • Thin or weak nails and hair

Luckily, collagen supplementation helps improve overall skin health and regeneration, elasticity, hydration, and reduces signs of aging. It also promotes hair growth

Do Hair, Skin, and Nail Supplements Work?

Hair, skin, and nail supplements can certainly work, especially when the root cause of the concern is a nutrient deficiency that the supplement helps correct. All the nutrients listed above, especially collagen protein, have scientific support for their use in various skin concerns, including hair and nail issues.

Choosing high quality supplements from a reputable source is important to ensure the quality and purity of the supplements you purchase. Because dietary supplements aren’t very well regulated, there have been many cases of over-the-counter supplements failing to contain ingredients and dosages as listed on the label or being contaminated with toxins, such as heavy metals.

Are Hair, Skin, and Nail Vitamins Safe?

Generally, yes, quality supplements containing nutrients found in food are safe. However, there may be individual considerations based on a person’s medical history and medication use.

Always discuss new supplements with your doctor, especially if you take a medication or have a medical condition. Your provider can also do testing to identify deficiencies in nutrients such as biotin or omega-3 fats.

In addition, please note that high-dose biotin may interfere with thyroid, vitamin D, and other blood test results. Please discontinue use for a few days before blood testing or work with your doctor for guidance.

How Long Do Hair, Skin, and Nail Vitamins Take to Work?

Unlike some supplements, where you may notice immediate benefits, supplements targeting hair, skin, and nails may take some time to display their full effect.

Skin cells turnover anywhere from 40 to 56 days, depending on your age and other factors. It can take hair and nails several months to grow to the point where you can observe a change. Because of this, we recommend using hair, skin, and nail supplements for around two to three months to gauge the full benefit, although some will notice improvements much sooner.
