18 Benefits Of Biotin


Biotin is a part of B complex vitamins. It is popularly known as vitamin H. This water-soluble vitamin has a lot of health benefits.

It is vital and beneficial for humans to consume adequate biotin. It is also a beauty vitamin broadly popular in the skincare industry.

You might see a lot of cosmetic products using biotin. The massive hype about biotin is that it promotes healthy hair, skin, and nails.

Moreover, it regulates blood sugar levels without many side effects. Even pregnant ladies require biotin for healthy embryonic growth.

You might want to learn more about this crucial vitamin since you landed here to know its benefits.

This article will end your quest to find all the positive effects of biotin on your body. Follow up to find out.

Benefits Of Biotin

Biotin is used as a vital source of producing energy in the body. This simple vitamin property helps sustain the proper functioning and maintenance of our body parts.

Not to miss, overdoing anything could be disastrous; the same is valid with biotin. Hence, if someone consumes biotin in access, they may also go through biotin side effects.

The human body needs this vitamin to stay healthy and fit. The reason is that biotin helps[1] in the functionality of the liver, nervous system, eyes, and more organs.

On the other hand, biotin also helps improve the treatment of certain medical conditions. Given below are a few benefits of biotin –

  1. Might Treat Hypoglycemia

    Hypoglycemia is the condition[2] of low blood sugar in the body. This problem comes when glucose in our body drops below a healthy range.

    Hypoglycemia is quite commonly observed in people with diabetes. It is a cause of excessive medicinal intake for diabetes.

    Biotin might help improve[3] hypoglycemia by boosting blood sugar levels.

  2. Might Help Prevent Or Cure Hyperlipidemia

    Hyperlipidemia is another condition[4] of blood when it has too many lipids. The lipids that the blood may contain in this condition include cholesterol and triglycerides.

    This condition increases the risk of blockages due to the heavy concentration of fatty deposits in your arteries.

    Biotin might lower the risk[5] by eliminating unwanted fatty deposits and lipids which may also lower the risk of cardiovascular diseases.

  3. Glucose Control

    Biotin helps a lot in the control of glucose in obese patients. This impact[6] is witnessed when biotin is combined with chromium histidine.

    It might lower blood sugar levels in cases of diabetes or obesity.

  4. Role In Pregnancy

    There also have been few proofs of biotin becoming successful in prenatal care. Pregnant women usually have a deficiency of biotin in their bodies that can be fatal.

    Both baby and mother need adequate biotin. The deficiency of the vitamin may affect the fetus’s development.

    Hence, it is recommended[7] for pregnant women to keep regulating their biotin-rich food intake.

    That is why they generally consider consuming biotin supplements. On a safe note, avoid these supplements. The main focus should be biotin-rich food during pregnancy.

    Even breastfeeding mothers need higher[8] biotin than usual because the body readily breaks down available biotin.

    Foods like eggs, avocados, and sweet potatoes might serve the purpose.

  5. Skin Health

    Biotin has also been seen as a good source for the maintenance of your skin health and boosting it. It is because people with biotin deficiency tend to have skin problems.

    These skin problems include[9] red or scaly rashes. Since this vitamin has a good hand in fat metabolism.

    Therefore, it could be witnessed to have effects on the skin too. Although, people without dieting deficiency do not seem to improve their skin health with access to consumption of it.

  6. Treating MS

    Biotin has also been connected with the treatment of multiple sclerosis.

    It is an autoimmune disease that damages the protective covering of nerve fibers in the brain, spinal cord, and eyes.

    This covering is called myelin. Biotin plays a major role[10] in the production of myelin.

    People with MS are recommended to consume doses of up to 300 milligrams of biotin regularly. This will help in the reduction of chronic disability.

  7. Good For Diabetes

    Diabetes is a common yet alarming concern. Luckily some studies have found that biotin has some benefits for people suffering from type 1 and type 2 diabetes.

    Biotin might improve[11] insulin resistance by increasing insulin secretion. It helps control glucose by bringing down blood sugar levels.

    Hence type 2 diabetes patients might experience better blood sugar regulation.

    A study[12] suggested that biotin helps prevent kidney problems and damage in people with insulin-dependent type 1 diabetes.

  8. Boosting Hair Health

    A large proportion of people believe that biotin supplements can help improve hair health. It is used in hair care products for the same reason.

    It gives shine, volume, and strength to your hair. Biotin may also regulate blood flow which is a bonus for a healthy scalp.

    It may also promote[13] fast hair growth and reduce breakage. Normally, dietary biotin is enough to maintain healthy skin and hair, some people suggest supplementation.

    Still, there isn’t much medical evidence to prove it right. Supplementation may or may not help to reap these benefits.

    However, if you have bad hair health due to biotin deficiency, you are likely to see good results.

  9. Keep Nail Health Intact

    Nails are prone to damage. They might crack or get rough over time. To avoid brittle nails, keep your diet rich[14] in biotin.

    It might additionally give a glossy and smooth look to the nails. They might grow faster, healthier, and stronger.

  10. Boosts Metabolism

    Biotin is an essential vitamin for improving[15] metabolism. It uses up fats, carbohydrates, and proteins present in the body to release the required energy.

    Accelerated metabolism may also aid the process of weight loss.

  11. Tissue Repair

    Biotin is required by the body for muscle growth and development. Biotin has dual benefits for muscles and tissues.

    Firstly, it has anti-inflammatory and antibacterial properties. This helps to reduce[16] the risk of muscle damage and other threats to growth.

    Secondly, it works actively to repair damaged tissues and muscles. Thus, the repair of muscles takes very less time.

  12. Boosts Brain Function

    Just like other body parts, biotin is required for healthy brain function. Vitamin H( biotin) is used by the brain for the formation of the myelin sheath[17].

    It is a protective cover that prevents damage and injuries to the brain. As biotin also promotes better blood flow, it might improve[18] cognitive function.

    It boosts neurotransmitter activity and keeps your nervous system intact. It aids in transmitting nerve signals.

    Like other B vitamins, biotin works wonders for memory power. People with a good biotin intake might be more resistant to neurodegenerative disorders.

  13. Vital For Thyroid Function

    Key glands of the body regulate normal functioning. Biotin is required to sustain healthy thyroid function.

    Sleep, hunger, pain, weight, and energy are also regulated by biotin. If you experience unhealthy weight gain or fatigue, increasing the biotin dosage might help[19].

  14. Refreshes Mood

    Fatigue and sadness strike in the absence of good metabolism. Biotin provides energy which also rejuvenates the mood.

    A study[20] has shown that it could also help in lowering the occurrence of anxiety, depression, and stress symptoms.

  15. Important For Healthy Cell Growth

    Biotin is essential for the formation of DNA. It ensures that genetic information is precise and equally distributed among the cells.

    Therefore, biotin is important for healthy cell development. That is why it is recommended to take more biotin during pregnancy. It improves[21] the chances of healthy embryonic growth.

  16. Antiallergic And Anti-Inflammatory

    B complex vitamins are a source of energy. Additionally, they keep harmful bacteria away.

    The anti-inflammatory properties help promote better heart health and muscles. It also prevents the recurrence of several allergies.

  17. Immunity Booster

    Biotin is required for the formation of white blood cells. Thus, biotin-rich foods are the best way to get enough biotin.

    It strengthens immunity. A deficiency of biotin makes you prone to several health issues.

  18. Little To No Risk Of Overdose

    There have been studies about biotin supplements carrying very little risk which is possible even in high doses.

    Biotin is water soluble which makes it quite impossible to overdose on it. This is because the water-soluble property flushes out the excess biotin in your body through urination.

    So, there can be a few worse impacts of excess consumption of biotin in your body.

Dangers Of Biotin Deficiency

Biotin deficiency can be very hazardous[22]. Common symptoms of such deficiency include

  • Brittle nails
  • Rashes
  • Hair thinning
  • Disturbing the glucose metabolism

Taking precautions such as fresh and healthy biotin foods might eliminate the risk of deficiency.

An intake of 30- 100 micrograms of biotin every day is sufficient for a healthy person. The recommended daily allowance is more for pregnant and lactating ladies.


Biotin or vitamin H belongs to the class of B complex vitamins. It is a key component for healthy body functioning.

It works wonders for the body, both internally and externally. The brain, heart, and nervous system work efficiently when you keep up with the required daily amounts of biotin.

It might even help you manage weight and get your desired body shape. It is best to avoid supplements and eat biotin-rich food till the doctor prescribes supplementation.

Excess biotin is removed by urine as it is water soluble. So, it is largely safe and has no major health hazards.

Nausea or digestion problems are rare symptoms to be seen. Overall, biotin is a safe and healthy vitamin to consider.
