How Biotin Works- Pharmacology
Biotin is a cofactor for carboxylase enzymes that catalyze critical steps in the metabolism of fatty acids, glucose, and amino acids.[3]
Biotin also plays an important role in histone modification, gene regulation and cell signaling. [4]
Health Benefits of Biotin
Biotin may help in the treatment of brittle nails and is also required for maintaining healthy hair and skin.
It may also help in reducing triglyceride as well as blood glucose levels and in the treatment of multiple sclerosis.
Biotin helps in Maintaining Healthy Hair and Skin
Biotin may help in maintaining healthy hair and skin and its deficiency leads to skin problems such as skin rashes and infections as well as hair loss.
Although biotin helps in maintaining the health of hair and skin and its deficiency may lead to problems.
But there is no evidence that biotin supplementation improves the health of hair and skin in normal individuals who do not have a biotin deficiency.
Confidence level: Moderate
According to a review article published in 2002, biotin deficiency leads to skin infections and hair loss. [5]
Another study also proved that biotin deficiency leads to scaly dermatitis and the symptoms could be reversed by supplementation with biotin. [6]
A study of 2016 showed that hair loss was observed in women with low biotin levels and treatment with 5 mg biotin daily for 3 months helped in hair growth. [7]
There are many studies that have shown that biotin deficiency is related to hair and skin problems. [8] [9]
However, the role of biotin in improving skin and hair health in normal individuals is not clear.
Biotin may Help in the Treatment of Brittle Nails
Biotin may help in increasing hardness, firmness and thickness of nails. However, more research is required to confirm the role of biotin in the treatment of brittle nails.
Confidence level: Moderate
According to a study of 1989, supplementation with 2.5 mg per day biotin helped in the treatment of brittle nails. [10]
According to another study of 1993, biotin supplementation increases nail plate thickness and helps in the treatment of brittle nails. [11]
Another study of 1990 also proved that biotin supplementation increases the thickness of nails and reduces their splitting. [12]
Biotin may Help in Reducing Triglyceride Levels
The increase in fatty acid oxidation by biotin might be a possible explanation for the decrease in triglyceride levels.
However, more research is required to confirm the effect and the exact mechanism of how biotin decreases triglyceride levels. [13]
Confidence level: Moderate
According to a study of 1980, biotin supplementation increased plasma biotin levels and reduced the level of circulating triglycerides. [14]
According to another study of 2006, biotin supplementation helps in reducing triglyceride levels and may be helpful in the treatment of hypertriglyceridemia. [15]
Biotin may help in Reducing Blood Sugar
Biotin improves glucose metabolism and promotes glucose utilization and may help in reducing blood glucose levels.
Confidence level: Low
According to a study of 1993, biotin administration helps in reducing blood glucose levels in patients of type 2 diabetes. [16]
There are many studies that have proved that biotin in combination with chromium helps in reducing blood glucose levels. [17] [18] [19]
However, more research is required to understand the role of biotin alone in the reduction of blood glucose levels.
Biotin may help in the Treatment of Multiple Sclerosis
Multiple sclerosis occurs due to damage in the protective covering of nerves. Biotin may help in repairing the protective covering of nerve fibers and also helps in preventing the degeneration of nerve fibers. [20]
Confidence level: Low
According to a study of 2015, high doses of biotin may have some impact on disease progression and permanent disability in patients with progressive multiple sclerosis. [21]
According to another study of 2016, a high dose of biotin helps in reversing multiple sclerosis-related disabilities in patients with progressive multiple sclerosis. [22]
Dosage
The following doses have been studied in scientific research.
- For treating biotin deficiency: 10 mg per day. [23]
- For the treatment of brittle nails: 2.5 mg per day for 6 months. [24]
- For reducing triglyceride levels: 20 mg per day for 28 days. [25]
Precautions
Biotin is possibly safe when taken by mouth in appropriate doses. Biotin may interfere with the results of certain blood tests which may lead to an incorrect diagnosis. [26]
Drug Interactions
Biotin might weaken the effect of certain medications. Consult your doctor before taking biotin if you are taking any drugs regularly. [27]
Overdose
There is no evidence in humans that biotin is toxic at high intakes. However, high doses may interfere with laboratory tests and may lead to an incorrect diagnosis. [28]
For children
Biotin is possibly safe for children when taken by mouth inappropriate manner. [29]
Pregnancy and Breast Feeding
Biotin is possibly safe during pregnancy and breastfeeding when taken in appropriate doses. [30]
Existing Bodily Conditions
If you have any medical conditions check with your doctor before taking biotin. [31]
