What is the recommended dosage of biotin supplements for hair loss? And will it cause my metabolism to slow down if it is already fast?

What is the recommended dosage of biotin supplements for hair loss? And will it cause my metabolism to slow down if it is already fast?

None: There is no recommended dosage; biotin deficiency is extremely rare, and most cases are due to chronic consumption of raw egg whites (due to avidin in them). I don't think the supplements will necessarily cause harm, but without documented biotin deficiency, I doubt they will do any good, either. ...Read more

Hair Loss (Definition)

Hair loss, otherwise known as alopecia, can be caused by different reasons, including damage to the hair shaft or follicles or fungal infections. There are two main types of alopecia. Alopecia areata occurs when the body's immune system attacks hair follicles and causes hair to fall out. Androgenetic (or androgenic) alopecia, on the other hand, is an inherited form of hair loss. With alopecia areata, hair can fall out in patches all over the body. With androgenetic alopecia, hair on the head first thins and then falls out. In men, this is called male pattern hair loss; in women, it is called ...Read more

Had major surgery & want to minimize hair loss if it happens. Dr. said take 10 mcg biotin. Is this right dose & does biotin really help with hair loss?

Had major surgery & want to minimize hair loss if it happens. Dr. said take 10 mcg biotin. Is this right dose & does biotin really help with hair loss?

Doubt it: Biotin deficiency is rare, but can occur in persons with genetic mutations, on long-term antibiotics or anti-convulsants, or who eat a lot of raw egg whites. There is no good evidence that this easily available, over-the-counter supplement is the magic potion to grow hair or prevent hair loss. Biotin is safe to take at normal recommended doses (the Mayo Clinic website recommends 30-100 mcg a day). ...Read more

How much biotin is recommended to take? I'm 36yrs old weigh 240 and have noticed my hair thinning and have noticed some hair loss. Have heard a lot biotn

None.: If you simply eat a reasonable diet consisting of fruits, nuts, green vegetables, and lean meat you should not need any extra vitamins or supplements of any kind. Thinning hair can be a sign of several different health issues (including stress), so see your doctor for evaluation. ...Read more

Hypothyroidism. 2500 mcg biotin daily. I just started taking dobble dose. Reason hair loss. Is that too much?! thanks in advance

Biotin: Biotin is a water-soluble vitamin, so excess amounts in your blood get filtered out by the kidneys and don't accumulate, so there is low risk of toxicity. Biotin is unproven in improving hair loss, so increasing doses above standard supplements is unlikely to provide any additional benefit. Biotin occurs naturally in leafy green vegetables, particularly swiss chard, and peanuts. ...Read more

I was told to take 15000 mg of biotin for hair loss. Is that to much should I get a nother oppinon?

See a Dermatologist: Biotin deficiency is rare, but can occur in persons with genetic mutations, on long-term antibiotics or anti-convulsants, or who eat a lot of raw egg whites. There is no good evidence that this easily available, over-the-counter supplement is the magic potion to grow hair or prevent hair loss. Biotin is safe to take, but 15000 mcg per day is over 100 times the usual dose, so is not advisable. ...Read more

I take biotin 10, 000 mcg Solgar. And so far I'm breaking out so much and getting painful itchy back acne. Help? I need biotin for hair loss nd thining

Not the biotin: Biotin is used to help with hair loss and nail growth as well as some skin conditions. It should not cause back acne or rashes unless you are allergic to it. You can try decreasing the dose or holding it for a few weeks to see if your acne improves but if it doesn't you should see your doctor to discuss causes and treatment options. ...Read more

I've been taking 5, 000mcg of Biotin once a day for about 8-9 months for hair loss and haven't seen any significant changes. What should I do? I'm 16.

Worthless: I am sorry you have not had your hair loss evaluated, but were given a "pop" remedy that seldom helps. Get a proper evaluation. If it is hypothyroidism, your life depends on proper treatment. If it is telegen effluvium, perhaps a cause can be found. If it is alopecia areata, Rx will likely fail and you can adapt. ...Read more

I'm taking cellcept and I asked my Rheumi if I could take biotin and she said no. I'm experiencing a lot of hair loss and it's depressing.?

Biotin: Isn't the treatment to your hair loss, and your treating rheumatologist has a logic behind advising against using it. Hair loss can be due to your original disease or another problem, cellcept isn't known for this side effect, kindly ask to be seen by a dermatologist for evaluation, best wishes ...Read more

My age is 24 years now. I am facing heavy hair loss problem. Have family history of hair loss. Some suggested me to use biotin btn 5mg tablets.

Get evaluated: If you're a man with early onset of male pattern baldness, either embrace it or ask your physician about medications and surgery. Otherwise, get evaluated so you'll know whether it's telogen effluvium, seborrhea, alopecia areata, hypothyroidism. or one of the others. Biotin's not the key, and treatment may be easy or impossible depending on the cause. ...Read more

I have been using minox & fin along with biotin (5mg) for my hair loss. Can long term biotin use cause hepatitis? (i came across sources claiming that)

I have been using minox & fin along with biotin (5mg) for my hair loss. Can long term biotin use cause hepatitis? (i came across sources claiming that)

Unlikely: Vitamin b7 is well-tolerated when taken as prescribed. There are no reported cases of adverse drug reactions or toxicity. Biotin is water-soluble and can be flushed out in the urine. Though a vitamin b7 overdose is rare and is quite unlikely to cause serious complications, side effects could be seen in people who have been overdosing on biotin for a long time, but do not include hepatitis. ...Read more

I am 24 year old guy suffering from hair loss. I've been on biotin and rogaine medication for about 2 years, haven't seen noticeable difference. Help!

Often fails: Biotin isn't going to help. If you have alopecia areata, nothing will help. This is probably too long for telogen effluvium. Especially if you're naturally blessed with a lot of great body hair and a thick beard, rogaine may not slow male pattern baldness. Shave your head, grow some great facial hair, hit the gym, and embrace your full masculinity. Nothing looks better than a buffed, balding man. ...Read more
