Health Benefits of Biotin: What Does the Science Say?

Biotin deficiencies are relatively rare, but they can cause skin, hair, and nail problems. However, some people — such as pregnant women and people who drink high amounts of alcohol — may develop mild deficiencies. Because biotin helps add volume, people with flat, limp hair can really benefit from a biotin shampoo. This shampoo from Hask combines biotin with plumping collagen and caffeine to stimulate the scalp and boost the hair at the root.

Foods and Drinks to Help Soothe COVID-19 Symptoms

Anyone who has a deficiency can increase their biotin intake by consuming foods rich in the vitamin or taking biotin supplements. But because people with a deficiency often show symptoms of hair loss or a scaly red rash, some doctors and supplement companies recommend increasing your intake. No matter your hair type, this OGX shampoo may be a great choice for healthy, shiny hair. It’s formulated with biotin, collagen, and hydrolyzed wheat proteins to support hair growth.

It is the case that you can utilize it to treat a great number of conditions but depending on individuals, this has a personal usage to achieve their goal. Over the years, it has been revealed that using vitamin B7 for hair growth is a common target among a large community of thin hair people. Working more biotin into your system (whether through supplements or diet) is generally safe. In some rare cases, too much biotin from supplements can cause stomach issues, trouble sleeping and skin rashes.

Biotin Side Effects

However, on record, outside of acne which is an understandable consequence after taking some dose, these side effects are tolerable to children and most women who are the two vulnerable subjects. Anything that disrupts your gastrointestinal (GI) tract can also affect hair growth, she adds. The serum is easy to use, and it doesn't feel greasy or heavy on the hair. We apply a few drops to our scalp and massage it gently, and we leave it on for a few hours before washing our hair. Of course, like any supplement, there are a few potential downsides to consider.

An essential nutrient is one that your body can't produce or can't produce enough of and needs to function correctly. Don’t take more than the dosage listed on the package and stop taking biotin if you notice side effects. It’s also worth noting that some antiepileptic drugs — like carbamazepine, primidone, phenytoin, and phenobarbital — can lower biotin levels. Thus, it’s best — both for your safety and nutrition — to avoid raw eggs (2). The AI for biotin is 30 mcg for adults and 35 mcg for women who breastfeed (2).

Based on these promising results, ongoing research is studying how the AminoMar C extract affects hair fiber formation within the hair follicle organ using an ex vivo culture model. Additional clinical studies designed to further assess the use of Viviscal to increase hair thickness and hair counts using larger patient populations are currently under way. Together, these studies will help provide a more detailed understanding of the mechanism of this new drug to promote hair growth and add to the existing body of clinical evidence. Vegan Greens Natural Plant Biotin Powder promises to boost strength and vitality of your strands. Packed with the goodness of 23 wool foods and herbs, including amla, beetroot, bhringraj, hibiscus, tamarind, lemon and more, this powder can promote thicker hair, healthy scalp environment and improved hair growth.

In the viewpoint of scientists, lack of biotin is rare because of the fact that biotin is available in a wide range of food and a necessary amount of biotin that human body needs is pretty small. To be honest, the average person does not have to take biotin supplement. It’s important to understand what’s causing your hair loss, but this can take some detective work.

Popular Supplements That May Have Hidden Dangers

"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. High-dose biotin supplements can also interfere with certain medical test results, so tell your healthcare provider if you’re taking them, advises Barth. Biotin deficiencies are rare, so research into their symptoms is limited. However, a few studies have suggested causal links between biotin deficiency and some conditions.

Hair, nail, and skin health

This ensures that what’s listed on the label, in terms of active and inactive ingredients, is in the bottle, and the supplement is free of contaminants. Those who frequently enjoy raw eggs in recipes for mayonnaise, Caesar dressing, or eggnog may want to reconsider. A protein in raw eggs called avidin can bind to biotin, preventing its absorption.

One of the main reasons you’d reach for a biotin supplement is to reverse a biotin deficiency. “If you’re following a healthy, well-rounded diet, you’re probably taking in more than enough biotin on a daily basis,” adds Kubala. Over time, however, as more scientific research has been done, the question of whether biotin actually has any effect on hair loss and regrowth has been raised. In addition to biotin, the other B vitamins are important for healthy hair growth, including Vitamin B6, B12, and folic acid. In fact, Vitamin B12 helps hair cells and hair growth by promoting healthy hair follicles through the production of oxygen-rich red blood cells. Overall, we would recommend Ethereal Nature Biotin Hair Oil to anyone looking for a natural hair oil that promotes healthy hair growth.

If you're interested in purchasing a biotin supplement, make sure you have the go-ahead from a healthcare provider first. “Before you buy a supplement for a specific reason, like thinning hair or brittle nails, it’s important to rule out potential underlying causes for your symptoms,” says Kubala. “There are a number of common medical conditions that can affect the health of the hair, nails, and skin, including hypothyroidism and iron-deficiency anemia,” she says. Outside of these studies, there is no strong evidence to support taking biotin supplements or using biotin-added hair products to promote hair growth (2). As such, biotin supplements and biotin-added hair products are commonly advertised to support healthy hair growth or promote thicker, voluminous hair.

In fact, biotin has been found to interfere with the diagnosis of Graves’ disease and hypothyroidism (14, 15, 16). Though promising, it’s unknown if the participants had an existing biotin deficiency and if the same results would be found in men (13). 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). However, little is known about biotin’s role in hair health and whether this supplement can truly help.

While there is limited research on the effect biotin has on hair growth, people with a biotin deficiency may see healthier hair if they start supplementing. A biotin supplement can help correct a biotin deficiency and restore hair health and growth. No strong evidence supports using biotin supplements or biotin-added hair products to promote hair growth in non-deficient people. There are many causes for hair loss or hair thinning—pregnancy, medication, stress, tight hair styling, or just plain genetics, to name a few.

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. Although high doses are unnecessary, it's considered harmless if you take more than the RDA. Studies found no adverse effects in 10 to 50 mg/day to as much as 200 mg/day.

Therefore, biotin supplements are not sufficient to make changes in your hair and skin. If there are changes, they are so negligible that you feel discouraged. In spite of toxicity risks you may, unfortunately, be exposed to, it is vital to highlight that there is no official instruction related to the daily intake of biotin. Studies have revealed that two factors should be considered before doctors determine an appropriate dosage. They are also the factors that determine ‘how long does it take for biotin to work’.
