Although high doses are unnecessary, it's considered harmless if you take more than the RDA. However, human trials have not supported the efficacy of many of these remedies for this purpose. The Food and Nutrition Board has not set an RDA (Recommended Dietary Allowance) for biotin. You can typically get this amount of biotin from a healthy and balanced diet. If you want to increase your biotin intake, most supplements contain a much higher level of biotin than 30mcg.

Although there is little evidence of direct health consequences of biotin supplementation, excessive intake may interfere with laboratory test results.

However, the range of required supplementation may differ depending on individual circumstances.

Increasing biotin in your diet or via supplementation can be vital in correcting your deficiency. According to the National Institutes of Health, the average person in a western population consumes 35–70 mcg of biotin daily from foods they eat. For most people, a supplement will not be necessary as long as they are eating a healthy, varied diet. Further research is needed to support the use of biotin supplements for this purpose in healthy individuals. And while most people can take biotin supplements without any adverse reactions, Phipps says that it's best to pay a visit to your doctor before adding any supplements to your daily routine. Another consensus among the experts interviewed for this story is that there is not enough research to prove that biotin actually aids hair growth.
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. Biotin can be used topically—most commonly as an ingredient in shampoo—or taken orally as a supplement. But keep in mind that taking supplements should only be done if you're not getting all of the vitamins you need from your diet. "You can maintain a healthy biotin level by eating meat, eggs, fish, seeds, nuts, and some vegetables like spinach, broccoli, and sweet potatoes," says Friese. "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."

Do Thyroid Medications Contain Iodine? The Answer is Yes
This effect helps improve the structural integrity of both your skin and your hair. For instance, seizure medications like carbamazepine (Tegretol), phenytoin (Dilantin), primidone (Mysoline), and phenobarbital (Luminal) may lower levels of this vitamin in your body (1). Biotin supplements are known for interacting with certain diagnostic tests that use biotin-streptavidin technology, and this can lead to incorrect results (14, 15, 16). “Inflammation interferes with signaling molecules that control the biological clock of the hair growth cycle, pushing follicles into the resting phase, telogen,” Peralta says. At WellnessVerge, we only use reputable sources, including peer-reviewed medical journals and well-respected academic institutions. You may also want to consider increasing biotin intake from food before considering supplement use.
Because of this many patients may walk around with so-called “normal” nutrient levels, when in reality they are actually suboptimal. You can also use this as a brief guide to help you figure out what is at the root cause of your hair loss. These conditions result in changes to both the absorption and the metabolism of biotin in the body.
Sometimes conditions that may seem inconsequential could indicate a bigger issue, which is why you should consult a professional. Samolitis breaks down one condition, telogen effluvium, which causes you to lose more hair than normal, but typically it remedies itself. You may take a biotin supplement to help with regrowth or length and attribute any growth to the biotin, when it may have nothing to do with the growth. It is important for individuals experiencing unexpected or unusual hair loss to speak with a doctor.
Herein, with the help of experts, you’ll get the lowdown on biotin for hair growth and what you need to know before investing your time and money in biotin-based supplements to treat thinning. Without further ado, keep scrolling to read more about what biotin is, how it interacts in the body, potential side effects, and more. Biotin (vitamin B7) is a micronutrient vital to energy production, nervous system health, and other bodily functions.
Let your doctor know if you've been taking biotin, especially if you need routine hormone tests. More research is needed, but there is also some evidence that biotin may improve symptoms of peripheral neuropathy and help people with diabetes gain control of their blood sugar. While the use of biotin is generally safe, the vitamin may interfere with some lab tests and medications, so you should tell your healthcare provider if you plan to use it.
This is one of the reasons that women often report an increase in hair growth once they start taking prenatal vitamins. If you have suboptimal levels (this doesn’t mean an overt deficiency) then taking these supplements WILL help with hair growth. Therefore, if you’re taking a biotin supplement and receive any diagnostic tests, it’s important to tell your healthcare provider.
