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.
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.
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.
Biotin is found in many foods and beverages, including milk, carrots, salmon, and nuts. It can also be taken as a supplement if needed. The recommended daily amount is 30 micrograms. However, taking biotin supplements is not recommended unless suggested by your doctor.
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.
Dosage and Safety
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.
Most of the websites touting biotin for hair growth recommend taking 2-5 milligrams (2,000-5,000 mcg) of biotin in supplement form each day, and many supplements are sold under the name Biotin 5000, indicating a 5000 mcg (5 mg) size.
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.
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.
Adults and teenagers—30 to 100 micrograms (mcg) per day. Children 7 to 10 years of age—30 mcg per day. Children 4 to 6 years of age—25 mcg per day.
After you stop using biotin, your nails will likely return to their original condition within 6 to 9 months. Store at room temperature away from moisture and heat. What should I do if I missed a dose of Biotin (Hair, Skin & Nails)? Skip the missed dose if it is almost time for your next scheduled dose.
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.
If no home remedies work for your hair loss, use a daily biotin supplement for at least 6 months to start seeing results.
The most common B Vitamin you might already be familiar with is Biotin—also known as Vitamin B7. If you've been looking into growth vitamins to thicken your hair, you're likely familiar with Biotin at this point. It's an essential growth ingredient often added to supplements that promote healthy hair and nails.
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. 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.
These data indicate that pharmacological concentrations of biotin do not affect classic liver damage tests.
Most commonly, biotin use can result in falsely high levels of T4 and T3 and falsely low levels of TSH, leading to either a wrong diagnosis of hyperthyroidism or that the thyroid hormone dose is too high.
We observed that long-term administration of biotin decreased systolic blood pressure in the SHRSP strain; also, a single dose of biotin immediately decreased systolic blood pressure in this strain.
The most commonly recommended time slot to consume biotin supplements is with your morning meal. The water-soluble nature of biotin will ensure that your body is absorbing it with the other nutrients in your meal.
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
