People at risk for biotin deficiency include people with BTD, chronic alcohol use, malnutrition, and IBD. Those who are pregnant and lactating as well as those who take certain medications are also at an increased risk. Due to the multiple factors involved in hair loss and thinning, supplementing with biotin without determining the cause can prevent or delay the appropriate treatment in instances where a biotin deficiency isn’t at fault. Despite these claims, though, there’s limited evidence to suggest that supplementing with biotin or lathering it through your hair promotes hair growth in non-deficient people. Signs of biotin deficiency include hair loss and a scaly, red rash around the mouth, eyes, and nose (3, 4).

Benefits and Side Effects of Biotin Supplements

According to Mount Sinai dermatology, biotin is needed in order to metabolize carbohydrates, fats, and amino acids, which are the building blocks of protein. These fish have nutrients, such as omega-3 fatty acids, protein, selenium, vitamin D3, and B vitamins, which may help promote strong and healthy hair growth. Foods high in protein, omega-3 fatty acids, iron, fat-soluble vitamins, and B-complex vitamins aid hair growth.

What are the side effects of biotin?

An ounce (28 grams) of sunflower seeds provides nearly 50% of your daily vitamin E needs, with a wide variety of hair-healthy B vitamins (21). Aim to meet your needs by eating vitamin-A–rich foods like sweet potatoes and avoiding too much supplementation. An RDA (Recommended Dietary Allowance) does not exist for biotin because there is not enough evidence to suggest a daily amount needed by most healthy people. Instead, there is an AI (Adequate Intake) level, which is assumed to ensure nutritional adequacy.

“For example, premenopausal women who bleed excessively may be losing iron, and anemia causes hair loss,” Dr. Bergfeld explains. If you find yourself browsing the hair care aisle or searching the internet for hair treatments, one thing that might pop up is biotin. This B vitamin has a reputation for helping your locks stay healthy, and it’s frequently recommended by dermatologists to help with hair loss. However, with the proper products and techniques, this concern can be addressed. Revamping your wash day routine with targeted shampoos, conditioners, and treatments can help restore strength and shine to your hair. Implementing hair care practices like gently drying with microfiber towels and applying heat protectants before using hot tools can also make a world of difference.

Research suggests that taking biotin supplements, even in high doses, has very little risk. That's due largely in part to the recommended daily amount (RDA) of biotin. According to Bhanusali, it depends on the source you're getting the RDA from, but typically between 30 and 100 micrograms — not milligrams — a day is sufficient. The National Institutes of Health (NIH) reports, for example, that a whole, cooked egg provides 10 micrograms per serving or 33 percent of the recommended daily amount. You can enhance your hair, skin and nail health even without a supplement.

Does Smoking Cause Biotin Deficiency?

For example, an ounce (28 grams) of almonds provides 48% of your daily vitamin E needs (19). Avocados are delicious, nutritious, and a great source of healthy fats. A cup (30 grams) of spinach provides up to 20% of your daily vitamin A needs (7). For example, 1 cup (144 grams) of strawberries provides 85 milligrams or up to 113% of your daily vitamin C needs (6). Create healthy, balanced meals using this visual guide as a blueprint.

They also provide an excellent source of vitamin E, which may support hair growth. One medium avocado (about 200 grams) provides 28% of your daily vitamin E needs (16). Research has shown that vitamin A can affect the production of sebum, which helps keep hair healthy (14). Spinach is also a great plant-based source of iron, which is essential for hair growth. Iron helps red blood cells carry oxygen throughout the body to fuel your metabolism and aid growth and repair (8). However, biotin deficiencies are uncommon if you consume a balanced diet.

For now, there isn’t enough research to definitively state that biotin can help grow hair.

There is little evidence suggesting that people with limited or no health issues benefit from consuming more biotin (1). That said, as with any supplement, speak with a healthcare professional before adding a biotin supplement to your routine. In addition to biotin, Garden of Life Mykind Organic Plant Collagen Builder contains several other vitamins, minerals, and botanicals that may help support healthy hair and skin, such as silica and vitamin C (4).
