In terms of your hair and scalp, taking too much biotin won't result in drastic damage. But while your magnificent mane might not be in danger, biotin could have adverse effects on your skin. “What I see most often is breakouts on the face, chest, and back,” Breana cautions.
While 5,000 mcg of biotin may work well for some people, for the most part, that may be too high for others who find that 200 mcg of biotin helps their hair grow. Look for a biotin vitamin that doesn't contain a ridiculously high dose amount like 10,000 mcg – this is usually excessive.
Regular intake of excessive quantities of certain nutrients can cause hair loss in some cases due to a temporary condition known as Telogen Effluvium. However, the effects of too much vitamin B7 - also known as biotin toxicity - remain unconfirmed.
But for strengthening hair, a minimum dose of at least 2000 mcg is often advised. To encourage faster hair and nail growth, some supplements are available with 10,000 mcg biotin. Mayo Clinic states that 10,000 mcg is a safe dose, as no adverse side effects have been noted to date.
Increasing your intake of biotin may help make your hair stronger and more resistant to falling out. Biotin is a common over-the-counter supplement that is touted to promote healthy hair growth.
How fast does biotin work for hair growth? Research pertaining to how quickly vitamins work in the body is limited, however, we have found that some begin to see and experience benefits approximately 30 days after you start taking biotin. It may take up to 90 days or longer for some individuals.
The bottom line. There's no strong evidence to support using biotin for hair growth or to prevent hair loss in people without a deficiency. Because hair thinning and poor hair growth are sometimes associated with a biotin deficiency, correcting a deficiency can help restore hair growth in some people.
Recommended Amounts
Instead, there is an AI (Adequate Intake) level, which is assumed to ensure nutritional adequacy. AI: The AI for biotin for men and women 19 years and older and for pregnant women is 30 micrograms daily. Lactating women need 35 micrograms daily.
Still, people who support its use often recommend taking 2 to 5 milligrams (mg) of biotin in supplement form daily in order to strengthen hair and achieve results.
Studies on biotin use and hair quality have been limited, but promising. For instance, a study published in The Journal of Clinical and Aesthetic Dermatology found that women with thinning hair who took biotin supplements had thicker hair than those who took a placebo after 90 days, and experienced no side effects.
An initial increase in shedding occurred during the first 31 days of biotin supplementation. After this initial period, shedding began decreasing over time. As the above graph displays, we can see an initial increase in shedding counts for the first 31 days of biotin supplementation.
Takeaway. Your body makes enough biotin on its own through your dietary intake each day. Therefore, you shouldn't take biotin supplements unless directed by your doctor. There are some rare health conditions that can cause some people to need biotin supplements on a regular basis.
So which supports hair growth more: collagen or biotin? Based on scientific studies, it seems that collagen has a better claim to improving the condition of your hair. However, both can actually be used together for well-rounded nutrition and countless health benefits, aside from promoting hair regrowth.
Sources of Biotin
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
A whole, cooked egg (50 grams) provides approximately 10 mcg of biotin, or approximately 33% of the DV ( 4 ). You should always cook eggs fully, both to reduce your risk of Salmonella poisoning and improve biotin absorption.

Biotin. Biotin, also known as vitamin B7, is a complex B vitamin that is often touted for having hair growth benefits. And some of that hype may actually be worth it. Biotin has functions in “creating red blood cells, which carry oxygen and nutrients to the scalp and hair follicles,” says Dr.
If you have a condition that's associated with biotin status, such as alopecia or intestinal malabsorption of biotin due to a variety of factors, supplementing with the nutrient may improve hair and beard growth, though it has limited effectiveness in healthy men ( 9 ).
