Pro biotin from NAKA contains 10, 000mcg of this important B complex vitamin. Biotin is a water-soluble vitamin necessary for normal growth and body function. Naka's pro biotin is a key regulatory element in gluconeogenesis, fatty acid synthesis, and in the metabolism of some amino acids.

“No studies have proven that biotin supplements will change the appearance of your hair, skin or nails,” Barth says. “But some people find that taking a biotin supplement helps them boost hair and nail growth. It's usually not harmful to try biotin for thicker hair or healthier nails.”

Biotin, also known as vitamin B7, supports many of your body's systems, including your nervous system, liver, eyes, hair, and skin. It helps the enzymes in your body carry out their jobs and keeps cells working as they should. Studies show that biotin supplements may help manage symptoms of diabetes.

But there's no evidence of high levels of biotin being harmful or causing toxicity, which is why you'll commonly see biotin supplements containing 5,000 to 10,000 mcg. (These levels ensure your body gets as much biotin as it needs and absorbs it in the small intestines.)

Although the evidence to support biotin alone for hair growth is weak and limited, the evidence is slightly stronger for preventing hair loss. Still, biotin supplements are only likely to prevent hair loss and promote hair growth in people with a biotin deficiency.

For now, there isn't enough research to definitively state that biotin can help grow hair. But biotin has been shown to help with preventing balding and hair loss. In fact, biotin is primarily used for alopecia - a condition that causes hair loss in all sexes.

It may take up to 90 days or longer for some individuals. The reason for the length of time before it starts working is by understanding your hair growth cycle. After 90 days, you will have formed new hair as well as faster growth to then compare your results from the days before taking biotin.

Biotin is also known as vitamin B-7. It forms fatty acids and glucose. It also helps metabolize carbohydrates and amino acids, and it aids in breaking down fat in your body. These functions make biotin an important part of creating the energy your body needs.

Biotin supplementation has been touted to improve skin texture, hair and nails. However, some people can experience side effects such as skin rash following biotin intake. Skin rashes are rare in those who take biotin.

Regular intake of excessive quantities of certain nutrients can cause hair loss in some cases due to a temporary condition known as Telogen Effluvium. However, the effects of too much vitamin B7 - also known as biotin toxicity - remain unconfirmed.

Biotin is safe to take - even at high doses. But taking too much can sometimes cause side effects like stomach ache, trouble sleeping, and excessive thirst. Talk to your healthcare provider if you think you've taken too much biotin. You can also contact Poison Control if you're having trouble reaching your provider.

No side effects have been reported for biotin in amounts up to 10 milligrams a day. However, check with your health care professional if you notice any unusual effects while you are taking it.

What is the most important information I should know about Biotin (Hair, Skin & Nails)? You should not use this product if you are allergic to biotin. Before using biotin, talk to your healthcare provider.

When taken by mouth: Biotin is likely safe for most people when taken in doses up to 300 mg daily for up to 6 months. But it is more commonly used in lower doses of 2.5 mg daily. When applied to the skin: Biotin is likely safe for most people when applied in cosmetic products that contain up to 0.6% biotin.

Studies on biotin use and hair quality have been limited, but promising. For instance, a study published in The Journal of Clinical and Aesthetic Dermatology found that women with thinning hair who took biotin supplements had thicker hair than those who took a placebo after 90 days, and experienced no side effects.

For the most part, biotin supplements are safe to take. “It likely will not be harmful if taken in excess - over and above daily recommended levels - as it is water-soluble, but it also may not be beneficial, especially if not needed,” says Richard.
