        What is Biotin and what functions does it provide?

        Biotin is a part of the B-Vitamin complex. Also known as Vitamin B7, Vitamin H and Coenzyme R, the main role of this water-soluble essential nutrient is to act as a coenzyme and help with energy production of your body cells and protein metabolism.

        • Fatty acids – Providing building blocks of healthy cells in your body
        • Glucose – What your body uses for energy, which originally comes from food consumption

        Is Biotin the ultimate hair loss cure? Biotin products are one of the most recommended supplements by doctors for people suffering from hair loss or thinning hair (also known as Alopecia) as well as for those looking for hair growth products.

As a side note, most of them all appear to be taking biotin supplement products on a DAILY basis and swear to have substantial hair growth results.

        Also, a frequently asked question is how biotin for African American hair growth works. In short, it really depends on an individual, not based on a race or ethnicity. Biotin gives faster hair growth results for some individuals, while taking more time for others.

        Biotin dosage: How much Biotin for hair growth?

        First, let’s start with the general recommended dosage.

        General recommendation for biotin supplement dosage:

        The recommended daily dose of biotin is 30 mcg (micrograms) for adults over 19. If you are pregnant, the recommended dosage is 30 mcg (micrograms) and if you are a breast-feeding mother, 35 mcg is recommended.

        Here is a Biotin dosage chart:

        biotin dosage for hair loss

        • 0 – 12 months: 6 mcg
        • 1 – 3 years: 8 mcg
        • 4 – 8 years: 12 mcg
        • 9 – 13 years: 20 mcg
        • 14 – 18 years: 25 mcg
        • 19 years + : 30 mcg
        • Pregnant women: 30 mcg
        • Breastfeeding women: 35 mcg

        But also keep in mind that while the above chart is the general recommended dosage suggestion, what US Food & Drug Administration recommends is higher: 300 mcg of biotin. This amount is 10 TIMES HIGHER than the above general recommendation which is 30 mcg.

        Then, what’s the right biotin dosage for hair loss?

        As you probably already know, most people with hair loss are taking A LOT HIGHER dosage of biotin tablets for hair growth than what is suggested. The good news is there are little to no major side effects reported so far.

        Why high dosages? First, you want to get the maximum benefit out of this hair essential vitamin. Since Biotin is water soluble, any excess amount your body can’t consume will pass it through. Therefore, one should not need to worry about biotin overdose.

        The most common dosages for biotin pills for hair growth are 1000 mcg, 5000 mcg biotin or taking 10000 mcg biotin a day to make hair grow (10000 mcg – the highest dose of biotin – is gaining more popularity recently).

        In fact, one of the best selling biotin (with 10,000+ reviews) has 10000 mcg which appears to be the best amount of biotin for hair growth and shows amazing before and after results for treating thinning hair as well as new hair growth on previously bald spots and receding lines.

        I’m already taking biotin for hair loss: How long to see results?

        This question is tricky, because how fast or how long Biotin takes to see results really depends on individuals and how their body processes nutrients as well as the level of metabolism.

        As a general guide, some people experience decrease in hair loss in as fast as two weeks based on hundreds of reviews we have read so far. Also most people start seeing biotin for hair growth results in 2 months.

        Any Biotin side effects including hair growth?

        Luckily, there are no major or life-threatening side effects when it comes to biotin (vitamin B7 supplement). WebMD also notes that Biotin is likely to be safe.

        But a few side effects that we came across include the increase of acne on the face, nausea, and frequent urination. If you need to take biotin yet have acne-prone skin, make sure to drink a lot of water (We recommend at least one liter a day in order to clear out your system).

        What happens if you have a deficiency of biotin?

        The common symptoms for biotin deficiency may include hair loss, changes in skin tone (dull), fragile nails, irritated skin (rashes), diabetes, nerve pain (tingling sensation in the hands or feet), frequent exhaustion, and even depression.

        What about overdose?

        As mentioned briefly above, Biotin overdose is pretty rare. Since Biotin is water-soluble, the excess amount of biotin flushes out itself from your body through urinating.

        In other words, when it comes to biotin side effects, you need to more worry about biotin deficiency than overdose.

        1. I have been suffering from thinning hair due to menopause and biotin has been a lifesaver. I see a lot of new baby hairs around my frontal hairline and noticed less shedding in the shower. (FYI, I am taking 10000 mcg and multi-vitamin)

        2. Please help. My hair has always been my pride and joy. I figured since it is pretty damn healthy, it could deal with some bleach damage. And I figured the master stylist who did all the color-corrections would know how much would be too much. I was wrong, and now I want to burst into tears every time I look at my hair or touch it. I just don’t know what to do. my hair has also NEVER been shorter than this and it breaks and falls out. What should i do to regrow hair?
