The Science Behind Biotin And Its Benefits

Biotin, sometimes referred to as vitamin B7 or vitamin H, is an essential micronutrient required for various bodily functions. Although biotin benefits are frequently linked to strong hair and nails, its advantages go far beyond these. In this blog, let's delve into the science of this micronutrient and understand the various health benefits of biotin. We’ll also look at some of the natural sources of biotin. 

What is Biotin?

Biotin belongs to the B complex group of vitamins known for their role in energy metabolism. The word “biotin” is derived from the ancient Greek word “biotos,” meaning “life” or “sustenance.”

Biotin is an essential component of the body's enzymes that break down materials like fats, carbs, and other substances. Low biotin levels are difficult to diagnose and often detected through symptoms. Some of the low biotin symptoms include thinning hair and a red, scaly rash around the mouth, nose, and eyes. 

Health Benefits of Biotin 

This B complex vitamin is often misunderstood, it is not just a superfood for your hair and nails. Biotin benefits can be seen in the overall health, including your nervous system, than just in your hair. 

Here's how biotin benefits your body:

1.Gives Energy 

As a coenzyme biotin helps to break down carbohydrates, fats, and protein for energy production. Biotin ensures that the body is converting the food into usable energy. 

2.Gene Expression

Biotin enhances how genetic information is utilized within cells. According to studies, biotin benefits the transcription of genes encoding cytokines and their receptors, oncogenes. These are genes involved in glucose metabolism and play a role in cellular biotin homeostasis. 

3.Fatty Acid Synthesis 

Biotin benefits the body by synthesizing fatty acids - the essential building blocks for cell membranes and hormones.

4.Amino Acid Metabolism

This micronutrient also helps in the metabolism of amino acids, the building blocks of protein.

5.Nerve Health

Biotin is believed to be beneficial for the nervous system as it aids in the healing of damaged nerves, particularly, in those suffering from degenerative conditions like multiple sclerosis. 

6.Prenatal Care 

Biotin plays a vital role in healthy pregnancy. Expecting mothers are often recommended a diet with biotin-rich foods as the body breaks down vitamins much faster during pregnancy. However, excess of biotin can pose problems for the unborn baby. It is always recommended to follow the doctor’s prescription for the correct dosage of biotin in pregnant ladies. 

7.Reducing Blood Sugar Levels in People with Diabetes

Lack of biotin can cause problems regulating glucose, or blood sugar. According to studies, treating type 2 diabetes with both biotin and chromium picolinate may be beneficial.

8.Biotin Benefits for Skin

Because of its involvement in energy production and nutrient metabolism, biotin may have an indirect positive impact on skin health by enhancing general well-being.

9.Improves the Health of Hair 

The benefits of biotin for hair are the most talked about. Biotin deficiency might result in hair loss and damaged hair. However, having a diet with biotin-rich foods can improve the quality and health of hair considerably. 

10.Improves Brittle Nails 

Biotin supplements aid in improving nail strength and reducing breakage in individuals with weak or brittle nails.
