Q&A

Frequently Asked Questions

What does Biotin do for your body?

Biotin, also known as Vitamin B7, is an essential water soluble vitamin that supports some of the most important daily processes in your body. It acts as a critical coenzyme in the metabolism of carbohydrates, fats, and proteins, helping your body convert nutrients into usable cellular energy. Biotin is also essential for supporting healthy hair growth, skin vitality, and nail strength by helping your body produce and maintain the keratin structures that keep them healthy and resilient.

Does Biotin really help with hair growth?

Yes. Biotin is one of the most well researched nutrients for supporting healthy hair growth. It plays a key role in the production of keratin, the primary structural protein that makes up your hair. Consistent daily Biotin supplementation helps support stronger, fuller, and healthier hair from the root up, and may help reduce brittleness and thinning associated with Biotin deficiency. Results are best seen with consistent daily use over time.

What is the difference between 5,000 mcg and 10,000 mcg Biotin?

Both NutraBio Biotin formulas deliver high potency Vitamin B7 in a clean vegetable capsule with no artificial colors, flavors, or sweeteners. The difference is simply the potency per serving. The 5,000 mcg option is ideal for those looking to maintain healthy Biotin levels as part of a daily wellness routine, while the 10,000 mcg option provides a higher dose for those looking to more aggressively support hair, skin, and nail health. Both are built to the same uncompromising NutraBio quality standard.

Can Biotin help with nail strength?

Yes. Biotin supports the production of keratin, the structural protein responsible for nail strength and growth. Consistent daily Biotin supplementation has been shown to support stronger, healthier nail structure and may help reduce brittleness and breakage over time. For best results, Biotin should be taken daily as part of a complete nutritional routine.

Is Biotin good for skin health?

Yes. Biotin supports the production of fatty acids that nourish and maintain healthy skin cells. It plays an important role in supporting the skin's moisture barrier, elasticity, and overall appearance. While topical skincare products address the surface, Biotin works from within to support the cellular processes that keep skin looking and feeling healthy, resilient, and vibrant over time.

When is the best time to take Biotin?

Biotin can be taken at any time of day, but taking it with a meal is generally recommended to support optimal absorption and minimize any potential digestive sensitivity. Taking it at the same time each day helps build a consistent routine, which is important for seeing the best long term results from Biotin supplementation for hair, skin, nail, and energy support.
