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.
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.
There is no specific antidote for overdosing on biotin. Excess in the body is rare, and since biotin is a water-soluble vitamin, it is excreted in the urine when in excess. Signs and symptoms of biotin overdose may include and are not limited to insomnia, excessive thirst, and urination.
No toxicity of excess biotin intake has been described. “It is a B vitamin, so it is difficult to overdose on it—most people will urinate out what they do not need,” says Johnson. “With that said, I suggest not taking more than the daily recommended dose of 30-100 mcg per day for an adult.”
“In May 2017, in the Journal of Drugs and Dermatology, Dr. Jerry Shapiro and his team did a comprehensive meta‐analysis of the scientific literature and conclusively determined that there is absolutely no scientific evidence supporting the use of biotin for hair loss,” Peralta says.
Strengthens and thickens: Biotin "is well known for its positive effects on hair including growing stronger thicker strands," says Friese. Protects: Because biotin strengthens hair, it is less likely to break off at the ends, promoting and protecting length, explains Friese.
Mayo Clinic states that 10,000 mcg is a safe dose, as no adverse side effects have been noted to date. Reassuringly, even “mega doses” of 300,000 mcg found no side effects in neurological research.
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.
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.
Can You Take Too Much Biotin? Not really! Even at higher dosages, excess biotin has not been shown to cause any harm. Biotin has been used in clinical studies and in the clinical setting in doses as high as 5 mg/day (5,000 mcg/day) for up to two years.
No side effects have been reported for biotin in amounts up to 10 milligrams a day. However, check with your health care professional if you notice any unusual effects while you are taking it.
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.
It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.
Can Supplements Cause Hair Loss? Yes, overdoing vitamins and nutritional supplements can cause hair loss. In addition to excessive selenium, taking too much Vitamin A can also cause hair loss.
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.
Biotin is generally safe even at high dosages. Side effects of biotin are minimal and easily reversed because excess biotin is easily passed by the body through urine. We recommend taking 500 mcg-5,000 mcg of biotin per day to support healthy hair, skin, and nails.
Most brands with biotin for hair growth recommend taking 2,000-5,000 mcg (2-5 milligrams) of biotin each day (many supplements are sold under the name Biotin 5000 which indicates a 5,000 mcg (5 mg) dose), but this is beyond more than doctors recommend.
The normal recommended biotin dosage for adults is 30 to 100 micrograms (mcg) per day. But there's no evidence of high levels of biotin being harmful or causing toxicity, which is why you'll commonly see biotin supplements containing 5,000 to 10,000 mcg.
A: It's referring to the potency of the vitamin. Biotin vitamins with 10,000mg are stronger than Biotin vitamins with 5,000mg.
High-dose biotin was defined as 1 milligram (mg) per day or more, which is many times greater than the recommended dietary intake of 30 micrograms a day.
Can biotin be harmful? Biotin has not been shown to cause any harm. However, supplements that contain biotin above recommended amounts may cause false results in some lab tests, including those that measure levels of certain hormones, like thyroid hormone.
These data indicate that pharmacological concentrations of biotin do not affect classic liver damage tests.
Though its use as a hair and nail growth supplement is prevalent, research demonstrating the efficacy of biotin is limited. In cases of acquired and inherited causes of biotin deficiency as well as pathologies, such as brittle nail syndrome or uncombable hair, biotin supplementation may be of benefit.
