How much biotin should someone take per day?

According to an analysis, most biotin-related false results occur in thyroid disease-related tests. The FDA reported an increase in adverse effects due to falsely high or low results. A high concentration of biotin in samples can compromise diagnostic tests in which biotin is a key component. An essential nutrient is one that your body can't produce or can't produce enough of and needs to function correctly.

If you're looking to grow your hair or increase thickness, instead of heading directly for a pill or chewable supplement, it's important to determine what could be causing the lack of growth. Sometimes conditions that may seem inconsequential could indicate a bigger issue, which is why you should consult a professional. By Regina C.

It's important to discuss your biotin use with your healthcare provider, especially before getting your labs done.

Supplements and diabetes

If considering biotin for your hair, consult your doctor to determine if it's right for you. Biotin can also have an interaction with other medications, such as anticonvulsants, which can decrease the levels of biotin in your body. Long-term antibiotic use may also negatively impact the biotin levels in your gut. Studies found no adverse effects in 10 to 50 mg/day to as much as 200 mg/day. But, it's important to keep dosage below 5 mg a day, says Elizabeth Damstetter, MD, a dermatologist and assistant professor at Rush Medical Center. That's because biotin absorbed in your bloodstream may interfere with test results for hours or days after the fact, such as thyroid hormone tests or a troponin test, which helps diagnose heart attacks.

However, keep in mind that dietary supplements are not regulated the way drugs are in the United States. That means some supplement products may not contain what the label says. You can easily meet these recommendations by enjoying a balanced diet. In fact, it’s estimated that people living in the United States get about 35–70 mcg per day of biotin (2). Those who received the hair growth supplement reported a visible increase in overall hair volume, scalp coverage, and thickness after the treatment period.

Biotinidase deficiency

Food should be the first choice when looking for sources of biotin. Biotin supplements are available alone, combined in a supplement with other B vitamins, or included in a multivitamin. About half of pregnant women in the United States have a mild biotin deficiency. If you have any unusual symptoms while taking a supplement, stop using it immediately and be sure to make an appointment with your doctor ASAP. Additionally, biotin has been shown to interfere with some lab results, so be sure to tell your physician you're taking the supplement before getting any bloodwork done. The metabolic requirements of pregnancy may also lead to biotin deficiencies in some cases.

What are the side effects of biotin?

Biotin (also known as vitamin B7 or vitamin H) is a water-soluble vitamin that serves as an essential cofactor for carboxylase enzymes in multiple metabolic pathways. Due to its relatively low cost and abundance of availability in cosmetic products, biotin has become the new trend for consumers wishing to have longer, healthier hair and nails. Current recommendations for biotin by the Institute of Medicine state that the daily adequate intake (AI) for adults is 30 μg/day [1]. Most healthy individuals meet these requirements through a well-balanced diet, though many still take up to 500–1,000 μg of biotin supplementation daily.

"Smoking causes inflammation throughout the body, which makes so many things worse, and hair loss is no exception," says Colaco. "Eating too few calories or not getting enough nutrients like iron or protein every day can cause hair loss as well." Hair supplements promising "longer, stronger" hair often contain more than the typical RDA of biotin.

First, you may consider working some biotin-rich foods into your diet. And you may already have some items in your pantry or fridge that fit the bill. But biotin has been shown to help with preventing balding and hair loss. Anything that disrupts your gastrointestinal (GI) tract can also affect hair growth, she adds. For instance, seizure medications like carbamazepine (Tegretol), phenytoin (Dilantin), primidone (Mysoline), and phenobarbital (Luminal) may lower levels of this vitamin in your body (1). Excess intake of this vitamin has also been linked to the measurement of false troponin levels — used to indicate heart attacks — leading to delayed treatment and even death (14, 15, 16).

And oral supplements may have more systemic side effects and interactions with other medications, so it’s especially important to check with your doctor before taking a supplement. Therefore, if you’re taking a biotin supplement and receive any diagnostic tests, it’s important to tell your healthcare provider. Biotin is found in many foods, such as egg yolks, liver, cauliflower, mushrooms, soybeans, beans, lentils, almonds, nuts, and whole grains. It’s also widely available in supplement form, either by itself or combined with other vitamins and minerals (3, 4). Biotin is also important in protein synthesis, specifically keratin production, among other processes.

But finding the right formula isn't a matter of simply choosing a product off the shelf and hoping that it works. High levels of biotin can interfere with numerous diagnostic tests, leading to false results. Be sure to speak with your healthcare provider if you’re taking these supplements. A study of 100 people found that a spermidine-based nutritional supplement prolonged a phase of active hair growth called the anagen phase.

If you're nurturing your hair and are still experiencing hair loss, there are in-office treatments to consider — specifically laser and platelet-rich plasma (PRP), which is recommended by Gross and Bhanusali. Samolitis suggests blood tests to indicate if you have a hormonal imbalance that may require something like a DHT (dihydrotestosterone, a metabolite form of testosterone) blocker that can be applied topically. "This is why I recommend when you have hair loss that you see a dermatologist because finding the correct diagnosis is really important," says Samolitis. Another consensus among the experts interviewed for this story is that there is not enough research to prove that biotin actually aids hair growth.
