Biotin, also known as vitamin B7 or vitamin H, is an important water-soluble vitamin in the B complex family. It helps the body turn food into energy by supporting the breakdown of carbs, fats and proteins. Biotin is found in foods like eggs, milk and bananas, and is best known for promoting healthy hair, skin and nails. A lack of biotin can lead to problems like thinning hair and skin rashes.

Biotin supplements help support healthy hair, skin and nails, making them a popular choice for improving appearance. Biotin also plays an important role in the nervous system, helping the body function properly, as well as aiding the breakdown of amino acids, carbs and fats.

Yes, you can take biotin and collagen together; in fact, these two supplements work well together, as biotin supports healthy hair and skin, while collagen helps maintain skin elasticity and bone strength. Collagen also provides extra nutrients, like vitamin C, which biotin doesn’t have, giving you more overall support.

Biotin supplements usually take 3 to 6 months to show noticeable results, though this can vary from person to person. For hair growth, some people may see small improvements within a month, while others might take longer, around 90 days or more, as biotin works with your hair growth cycles. For the best results, take biotin regularly, ideally at the same time each day, without missing doses.
