Biotin: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Biotin deficiency is very rare in the United States. Biotin helps turn the carbohydrates, fats, and proteins in the food you eat into the energy you need. For more in-depth information, see our health professional fact sheet. Women who cannot get pregnant and men should be able to get all the folate they need by eating a varied and balanced diet.
It’s recommended to consult your doctor if you develop any of these symptoms or suspect you have a deficiency. Pregnant or breastfeeding women should consume between 30 to 35 mcg per day. They also contain minerals like potassium and fiber to support your overall health. Although nuts are generally considered healthy, they are also high in calories and should be consumed in moderation — especially if you’re trying to lose weight. However, it’s important to avoid consuming too much organ meat as this can cause vitamin toxicity.

What is biotin and what does it do?

In the US, biotin as a non-prescription dietary supplement is sold in amounts of 1 to 10 mg per serving, with claims for supporting hair and nail health, and as 300 mg per day as a possibly effective treatment for multiple sclerosis (see § Research). Anyone who has a deficiency can increase their biotin intake by consuming foods rich in the vitamin or taking biotin supplements. It is important to note that no evidence shows that biotin improves skin health in people who do not have a deficiency of the vitamin. In some cases, fortified foods and dietary supplements are useful when it is not possible to meet needs for one or more nutrients (for example, during specific life stages such as pregnancy). Dietary supplements that contain biotin are often promoted to improve the health of your hair, skin, and nails, but there is little scientific evidence to support these claims.
However, research so far has shown no conclusive results to back up the claim that biotin is directly related to the improvement of skin and nail condition or in increased hair growth. Although biotin may be present in certain cosmetics, it is important to remember that it cannot actually be absorbed through skin, hair or nails. Biotin deficiency symptoms include hair loss, skin issues including rash, an appearance of cracking in the corners of the mouth, dryness of the eyes and appetite loss. Other foods that contain this vitamin are whole meal bread, salmon, pork, sardines, mushroom and cauliflower.

Good sources of vitamin B12

Food and Drug Administration (FDA) issued a warning based on reports of biotin supplements interfering with laboratory blood tests, causing incorrect results. Healthcare professionals are advised to instruct patients to stop taking biotin supplements for 48 h or even up to weeks before the test, depending on the specific test, dose, and frequency of biotin uptake. Treatment of partial biotinidase deficiency is also recommended even though some untreated people never manifest symptoms.

Managing Your Biotin Intake: Precautions and Considerations

You should be able to get all the vitamin B6 you need from your daily diet. Pantothenic acid cannot be stored in the body, so you need it in your diet every day. Taking 40mg or less a day of riboflavin supplements is unlikely to cause any harm. Taking 100mg or less a day of thiamin supplements is unlikely to cause any harm. No evidence in humans has shown a toxicity of biotin even with high intakes.
