Why Your Hair, Skin & Nails Need the Right Nutrients—And How Biotin Delivers

Many of us struggle with dull hair, brittle nails, or tired-looking skin simply because our diets and daily routines don’t deliver the consistent nutrients these areas need.

Stress, environmental factors, and even common styling products can strip away essential vitamins over time.

Biotin benefits support your hair and nails in many ways, along with other supportive nutrients, it plays a key role in helping rebuild and strengthen from within—leading to visibly healthier hair, nails, and skin when given the proper dose.

Many people wonder, ‘What is Biotin?'

"We find biotin to be very helpful for hair disorders," says dermatologist Wilma Bergfeld, MD. "It also makes nails thicker, and oral biotin is exceedingly safe, even in large doses. It’s primarily used for alopecia, the medical word for hair loss in men or women." "Biotin improves hair growth and helps with inflammation,” she says. “The hair follicle, the skin and the nails all benefit.

Does Biotin work alongside other supplements?

Early research suggests biotin may work synergistically with collagen, delivering even stronger support for hair growth, nail strength, and skin elasticity.

Preliminary studies and anecdotal reports indicate that combining biotin with collagen peptides can yield more robust improvements than either nutrient alone

Experts say yes—it strengthens brittle nails and reduces splitting. For the best Biotin results, look for high-quality supplements.

How does this help my brittle nails?

Numerous options are available for the treatment of brittle nails, including buffing and moisturizing, application of essential fatty acids, and ingestion of vitamin C, pyridoxine, iron, vitamin D, calcium, amino acids, and gelatin. A nutritional supplement that has been extensively investigated and recently shown promise is biotin, or vitamin H. The present results suggest that MSM could also be a good source of nutrition for nail health.

Still unsure what Biotin is good for beyond hair?

It also supports a clear, supple complexion by aiding healthy fat metabolism in the skin.

Research shows scaly rashes linked to biotin deficiency often clear up once biotin is replenished.

What's inside RenewGlow's Formula?

Biotin

Deficiency of this vital B vitamin (also known as Vitamin H) has been linked to hair loss and loss of hair color, as well as several skin problems. Keeping this nutrient at healthy levels in the body helps ensure full, healthy, strong hair, as well as smooth, radiant skin and stronger nails.

OptiMSM

If you were to lengthen the name of this, it would be “Optimal MSM (methylsulfonylmethane).” It’s “optimal” because it is the purest and only GRAS-designated MSM available. MSM is often contaminated by metals and other impurities, but our variety goes through a multi-stage molecular distillation process, helping ensure purified antioxidants for your body.

 

Benefits of this high-powered form of MSM include reduced fine lines and wrinkles, improved skin texture and elasticity, skin hydration, youthful hair, healthy joints, overall detoxification, and antioxidant and anti-inflammatory properties.

Vitamin c

Humans have no way of producing Vitamin C on their own, so they have to get it by from outside the body, such as by eating oranges. This essential nutrient is most known for boosting the immune system, but it is also a powerful antioxidant vital to skin and overall health. 

 

Studies have shown that Vitamin C has the power to reduce wrinkles and repair sun damage. What’s more: combining Vitamin C with Vitamin E and Zinc (all of which are in RenewGlow) can help prevent age-related vision loss.

Selenium

Another powerful antioxidant that helps protect cells from damage. Selenium is often used against dandruff, graying hair, and supports health skin.

Pantothenic Acid

Also known as Vitamin B-5, Pantothenic Acid is used for a wide range of health-boosting qualities. Most important to us are its effects on hair and skin health. Studies suggest Pantothenic Acid is helpful for thicker hair, skin irritations, acne, dandruff, and several other anti-aging qualities.

Zinc

Zinc is another one of those essential nutrients with a wide range of uses and health benefits. It is included in RenewGlow because of its usefulness in helping to stimulate hair growth and promoting skin health.

 

What’s more: combining Zinc with Manganese and Calcium (all of which are in RenewGlow) can help accelerate wound-healing, suggesting potential skincare benefits.

Vitamin B-6

Not to be confused with Biotin (Vitamin B-7), this nutrient is known for boosting energy and improving circulation. A healthy circulatory system is essential for any anti-aging efforts, as your cells need a steady flow of nutritious fresh blood.

Grape Seed Extract

You may have heard that red wine can help you live longer. That’s because of the grapes! In fact, grapes have been used as traditional treatments for centuries.

 

There’s strong evidence that suggests it is beneficial for cardiovascular and circulatory conditions. Even better: it is loaded with powerful antioxidants that help prevent cell damage.

Calcium

It’s well-known that Calcium is essential for healthy bones. It’s not so well-known that Calcium is also essential for healthy nerves, heart, and blood. All of these are vital to anti-aging efforts.

Silica

From bamboo stem extract, Silica is a premium compound of Silicon and Oxygen that is usually at very high levels when you’re young, because it’s essential to bone growth and body development.

 

It also happens to be the reason why children often have soft skin, perfect nails, and beautiful, full heads of hair. Deficiencies in Calcium are often linked to deficiencies in Silica. RenewGlow aims to solve both problems.

Gotu Kola Extract

This is an herb that’s commonly used in Chinese and Ayurvedic cultures to help against many types of infections and for brain, heart, and circulatory health, but its most relevant use for us is its skin healing and rejuvenation effects.

Frequently asked questions

What are the biotin benefits for hair?

If your hair is getting thin, turning brittle, graying, or if your skin is becoming chronically dry, wrinkly, and loose, then a complex Anti-Aging formula containing Biotin can help strengthen your hair and rejuvenate your skin. With the powerful combination of anti-oxidants, vitamins, and minerals in RenewGlow, can help you restore essential nutrients to youthful levels and neutralize the free radicals in your body that may be causing cell damage and aging.

2) Ample Anti-Oxidants– Antioxidants are absolutely vital to a healthy body, let alone healthy hair. Antioxidants neutralize free radicals, which are primarily responsible for damaged or dying cells in your body. RenewGlow contains high amounts of Vitamin C, Vitamin E, B Vitamins, and several other powerful antioxidants, such as Goji Berry Extract and Grape Seed Extract.

3) Complete Scientific Formula– On top of the high concentrations of Biotin and essential antioxidants, RenewGlow contains several rare, prized ingredients.
