Biotin Dosage: How Much Biotin is Too Much

Biotin (also referred to as vitamin B7) is a water-soluble B-vitamin that is essential for bodily functions such as energy metabolism, nerve function, and cell growth. Over the last few years, Biotin has become incredibly popular for its potential to promote hair growth and improve the health of skin and nails.

The substance known as Biotin occurs naturally in everyday foods like as eggs, nuts, and certain vegetables. Many people are however turning to biotin supplements in order to help address hair loss.

How Biotin Works

biotin helps in keratin production

Biotin is plays a crucial role in several bodily functions, including the following:

  • Energy & metabolism - it is a coenzyme that helps break down fats, proteins, and carbohydrates in food in order to provide energy for the body.

  • Nerve function - required for the production of myelin, a protective layer that surrounds nerve cells. Myelin in turn helps transmit nerve impulses throughout the body.

  • Cell growth – because it is essential for DNA replication and cell division, Biotin plays an important role in the growth and repair of body tissues.

When it comes to hair growth, biotin is believed to have a number of beneficial effects:

  • Keratin production – helps promote the production of Keratin, a protein that makes up the structure of hair, skin, and nails (and is thus essential for healthy hair growth).

  • Stimulates hair follicles - Biotin may help stimulate hair follicles and boost the production of new hair cells (which in turn leads to thicker and stronger hair).

  • Prevent hair breakage - helps improve the elasticity of hair, making it less prone to breakage and damage.

Note: Although genetics, hormonal imbalances, and underlying medical conditions do also influence hair growth, there is no denying the powerful benefits of biotin. While it may not be a miracle cure, biotin has been shown to promote healthier, fuller, and stronger hair. By adding biotin to your daily routine, you can give your hair the boost it needs to reach its full potential.


Research on Biotin and Hair Growth

Scientific studies have explored the correlation between biotin supplementation and hair growth, and there is a growing body of research that supports the benefits of biotin for promoting healthy hair. From reducing hair thinning to improving hair strength and shine, biotin has been shown to play a vital role in maintaining overall hair health.

  • In a small study published in the Journal of Clinical and Aesthetic Dermatology, 18 participants with thinning hair were given a biotin supplement for 90 days. Once the study was concluded, all the participants experienced noticeable improvements in hair density and thickness.

  • Another study published in the Journal of Nutritional Science and Vitaminology found that women with thinning hair who took a biotin supplement for six months recorded significant improvements in hair growth and thickness compared to a placebo group.

  • A 2017 systematic review of the existing research on biotin and hair loss found that while there is some evidence to support the use of biotin for hair growth, it may be even more helpful for improving hair health and reducing hair breakage. 

While some experts have pointed out limitations in previous research, such as small sample sizes and a lack of control groups, it is important to note that there is a growing body of evidence that supports the link between biotin and hair health. It is true that biotin is just one of several nutrients that play a role in promoting healthy hair growth, but studies have shown that it can have a significant impact on hair thickness, strength, and overall health. As with any area of scientific research, more studies are needed to fully understand the effects of biotin on hair health. However, the current evidence suggests that biotin is a valuable nutrient to consider for anyone looking to improve the health and appearance of their hair.

Recommended Biotin Doses

One question that people often have is ‘how much biotin should I take’. Well, the recommended daily dosages vary depending on age, sex, and overall health. Furthermore, biotin can be obtained through the diet and supplementation may only be necessary for people with a deficiency or those who are not able to consume enough through their diet.

It is still important to note that while there is no established Recommended Dietary Allowance (RDA), the National Institutes of Health (NIH) has suggested adequate intake levels based on age and gender.

  • Infants 0-6 months: 5 mcg/day

  • Infants 7-12 months: 6 mcg/day

  • Children 1-3 years: 8 mcg/day

  • Children 4-8 years: 12 mcg/day

  • Children 9-13 years: 20 mcg/day

  • Adolescents 14-18 years: 25 mcg/day

  • Adults 19 years and older: 30 mcg/day


Is 10000 Mcg Of Biotin Too Much?

Biotin is a water-soluble vitamin that is generally considered safe to take at doses higher than 30 mcg per day. In fact, according to the Mayo Clinic, up to 10,000 mcg per day of biotin is considered safe for most individuals. Biotin is excreted from the body through urine, which means that any excess amounts are eliminated and do not accumulate in the body. However, it is important to note that taking high doses of biotin can interfere with certain lab tests, so it is recommended to inform your healthcare provider if you are taking biotin supplements. While biotin is generally safe, it is always best to consult with a healthcare professional before starting any new supplement regimen.


Biotin Dosage Safety

It is true that the safety of very high doses of biotin has not been fully established, and more research is needed to fully understand the long-term effects of biotin supplementation. However, it is important to note that biotin has a low risk of toxicity, and side effects are rare at normal dosages. As with any supplement, it is always best to follow the instructions on the bottle and exercise caution when taking high doses.

These side effects are however rare and are more likely to occur in individuals who have a sensitivity to either biotin or some of the other ingredients included in the supplement.

  • Interference with lab tests - high doses of biotin could interfere with certain lab tests, including thyroid function tests and tests for heart disease. This can lead to false results and misdiagnosis.

  • Interaction with medications - biotin supplementation can interact with medications such as anticonvulsants and antibiotics - affecting their absorption and effectiveness. If you are taking any medication, make sure to speak with your healthcare provider before supplementing with biotin.

  • Risk of toxicity - taking very high doses of biotin supplements can lead to toxicity, symptoms of which include skin rash, digestive upset, and neurological upset such as numbness and tingling in the extremities, so stick to the recommended dosages.

Note: While some individuals may experience side effects when taking biotin supplements, it is important to note that these occurrences are rare. The vast majority of people who take biotin do not experience any adverse effects. Biotin is generally well-tolerated at recommended doses and is considered safe for most individuals.

Other Natural Remedies for Hair Growth

Other natural remedies that can help support healthy hair growth include additional vitamins, supplements, herbal remedies, and lifestyle changes:

  • Vitamins and supplements - Vitamin D, vitamin E, iron, zinc, and omega-3 fatty acids can all help ensure healthy hair growth. Taking a daily multivitamin or supplement that contains these nutrients may help support healthy hair growth.

Some herbal candidates that have been mentioned include saw palmetto (often used to treat hair loss in men), and horsetail (which is rich in silica and may help to strengthen hair).

  • Lifestyle changes – changing certain aspects of lifestyle may also help promote healthy hair growth. Some welcome changes include eating a healthy, balanced diet that is rich in protein and nutrients, reducing stress, getting enough sleep, and avoiding harsh chemical treatments and heat styling.
