This is usually not a problem, but there can be some unintended side effects from taking too much biotin. The Food and Nutrition Board has not found sufficient data to set an RDA for biotin, which is why you’ll only see AIs for this nutrient. The Food and Nutrition Board sets either an RDA (Recommended Dietary Allowance) or an AI (Adequate Intake) for vitamins and minerals.

However, while a person may get an upset stomach, there is no evidence to suggest these high doses are dangerous. "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. But having an excess of biotin doesn't necessarily provide hair with the benefits you may be seeking. Bhanusali, Samolitis, and board-certified dermatologist Shanthi Colaco all say that biotin is water-soluble, meaning what your body doesn't use, you urinate out.

May help to manage blood sugar

If you have noticed an INCREASE in hair loss after taking biotin, make sure to discontinue your dose immediately. The trick here is that giving this person thyroid replacement medication won’t fix the iron deficiency problem – for that problem the patient would need to also take iron. Those with hypothyroidism tend to have hair loss as one of their main symptoms. Women who suffer from conditions such as insulin resistance or PCOS often suffer from hair loss which mimics the male pattern (8) of hair loss. If you have hypothyroidism (up to 15-20% of women in the US do) then it will be necessary to fix this problem if you want your hair to grow back.

The Best Hair Products With Biotin

This article looks at why people need biotin, the recommended intake, sources, and any possible health risks. 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. 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.

Here is what you need to know about biotin, its relationship to healthy hair, and possible side effects. 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. The AI is an intake level that is assumed to be nutritionally adequate for most people, but the available evidence is insufficient to develop an RDA.

Bell peppers are chock full of vitamins C and A and biotin, essential for keeping hair healthy. Bell peppers come in various colors, including red, yellow, green, and orange. Legumes, such as chickpeas, lentils, black beans, and peas, are a good alternative for people who follow a vegetarian diet and want to consume more protein.

Biotin and hair growth

With its natural ingredients and easy-to-use formula, it's an excellent choice for anyone looking to improve the health of their hair. To help us get to the bottom of biotin and hair growth, we enlisted Annie Chiu, MD, board-certified dermatologist and founder of The Derm Institute. Los Angeles-based Dr. Chiu specializes in overall skin health (and just so happens to have great hair!) Here’s everything you’ve wanted to know about biotin for hair growth.

Is Biotin as Good as Advertised for Your Hair Loss?

You can read more about my own personal health journey and why I am so passionate about what I do. This side effect can be avoided by complexing biotin to other nutrients such as choline, B vitamins, silica, zinc, and/or selenium. Most people who experience this side effect tend to have hair loss if they use biotin by itself. When you eat foods that contain nutrients you will ALWAYS get several different types and doses of nutrients. Another very common reason for hair loss among women is hypothyroidism.

Of course, like any supplement, there are a few potential downsides to consider. It may take some time to see results, so you'll need to be patient and consistent with your use. Additionally, the product contains porcine hydrolyzed collagen, which may not be suitable for everyone. Finally, it's only available in one flavor, so if you're not a fan of berry, you may want to look elsewhere. For best results, apply 2-4 drops to slightly damp hair after washing or rinsing for best absorption. Biotin plays an important role in converting carbohydrates, fats and proteins into energy.

With 30–50% of men experiencing some degree of MAA by the age of 50, many are looking for ways to prevent further hair loss (10). I don't practice medicine anymore and instead specialize in helping people like YOU who have thyroid problems, hormone imbalances, and weight loss resistance. I also happen to formulate the best supplements on the market (well, at least in my opinion!) and I'm proud to say that over 80,000+ people have used them over the last 7 years.

Most people get adequate amounts of biotin from internal production and diet. Many foods — including egg yolks, nuts, and legumes — contain small amounts of biotin. Biotin supplements are generally safe to take, but they can interfere with certain lab results.

It is rare for a person to have a biotin deficiency, and most people in the U.S. naturally get enough from gastrointestinal bacteria and a balanced diet. Although some studies have suggested links between biotin deficiencies and alopecia, further analysis has not found conclusive proof of benefit among healthy individuals. 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). For example, researchers in one study prescribed a biotin supplement to 22 patients with low biotin levels for hair loss following gastric sleeve surgery (6).

Look for carrier oils that are lightweight and easily absorbed by the hair, such as argan oil, jojoba oil, or coconut oil. One thing to note is that the scent of this hair oil may be overpowering for some people. Additionally, the bottle may leak during shipping, so be sure to check it carefully when it arrives. One of the things we love about this hair oil is that it's weightless, so it doesn't leave our hair feeling greasy or weighed down. It's also easy to apply and doesn't require a lot of product to see results. We love that the serum is packed with natural ingredients, including Castor Oil, Caffeine, Rosemary Oil, and Biotin.

Meat has a lot of protein and iron, which are involved in the hair growth cycle. However, overeating red meat has been linked to other health issues, such as cardiovascular (heart) disease. Oysters are a good source of zinc, a mineral that supports the hair growth cycle.
