Biotin is an essential nutrient needed to break down carbohydrates, fats, and protein in the body. However, it is more popular for its role in hair and nail growth and is a common ingredient in most hair and nail products.  

Although biotin is obtained naturally from certain foods we eat, biotin supplements are popular as they contain high doses of biotin.

Biotin supplements are effective in promoting healthy hair and nails. People who use biotin supplements believe it strengthens the hair and prevents nail breakage. Biotin supplements come as capsules, tablets, or gummies.

In this article, you’ll learn about the best biotin supplements for hair growth and nails.

Are biotin supplements safe?

Yes. Biotin supplements are generally safe to use. 

Since biotin is a water-soluble vitamin, it can easily be excreted from the body and does not cause any severe harm.

How many biotin pills should you take in a day?

When taking biotin pills for hair and nail growth, you can take a pill daily.

Biotin supplements usually come in different strengths, which can be as low as 120 micrograms or as high as 10,000 micrograms. Although the recommended daily dose for adults is between 30-35 micrograms, which can be gotten from daily food sources, taking high doses of biotin for hair growth and nails isn’t usually harmful.

However, if you are on a high dose of biotin, it’s best to let your healthcare provider know, as it can interfere with specific test results.

What to consider when buying your biotin supplement

When buying biotin supplements, it’s best to read the labeling to know the strength, as these supplements have different strengths. Also, since most biotin supplements contain other ingredients, it’s best to check the labeling to ensure you are not allergic. You should avoid biotin supplements containing gelatin if you are a vegan.

Aside from pharmacies, you can easily buy biotin supplements from online stores like Amazon, and you won’t need a prescription for that. However, it’s also best to get your biotin supplements from reputable brands.

Lastly, before buying biotin supplements, it is advisable to speak to a healthcare provider to be sure your body needs it and that there won’t be any interactions.
