What are the functions and benefits of Vitamin B7?

Vitamin B7 is an important and essential player in our protein, fat and carbohydrate metabolism. Of remarkable significance is its function as a coenzyme. In this form, it supports enzymes in their task to supply and store energy and to convert amino acids, which are the components of proteins. They can work as neurotransmitters in the nerve system and they build body structures, such as muscles, skin, nails and hair.

As we already know, vitamin B7 or biotin helps our body to form a healthy skin, strong nails and bright hair.
It is also able to convert proteins and fats into carbohydrates, which are a supply for our energy metabolism. So, for example it helps our nerves and muscles to function properly.

Another very important task of biotin is the transformation of the DNA, which means that biotin is able to support the expression of genes. That is known for over 2000 genes.

Furthermore, biotin builds a special recycling mechanism in our body. It is stored by being bound to proteins, which can release biotin when they are degraded.

 

What deficiency symptoms of Vitamin B7 exist?

A hypovitaminosis of vitamin B7 is normally seldom, as it takes a long time of a lack to take effect. Some risk groups are people who have gut disorders, pregnant women, people, who are taking anticonvulsants or have a genetic preposition. The symptoms can be as followed:

  • hair loss, dry nails and skin problems
  • muscle pain
  • psychological disorders

 

What overdose symptoms of Vitamin B7 exist?

A hypervitaminosis of vitamin B7 is not known, as surplus vitamin B7 is excreted through the urine. Constant high amounts over 180 μg per day are a limit, but the research has shown that up to 10 mg there aren´t any noticeable side effects.

 

What else may you have to consider about Vitamin B7? 

Sometimes vitamin B7 and vitamin B8 are mixed up. Actually, vitamin B8, or adenyl acid (adenosine monophosphate) isn´t a vitamin but was thought to be a vitamin, when discovered and later to be found out, that it isn´t. Vitamin B7 or biotin can skinclearly be separated from adenosine monophosphate.
Another used name for vitamin B7 is vitamin H, which comes from the German words “Haut/Haar” (skin/hair).

Biotin helps with skin diseases, such as seborrheic dermatitis and other eczemas.

Vitamin B7 is absorbed in the gut through the so-called “SMVT”-channels, which stands for sodium multivitamin transporter.

Vitamin B7 was first discovered in 1898 as vitamin H and in 1901 it was found out that a watery solution contains a substance, which promotes the growth of yeast. In 1943 the first synthetic vitamin B7 was produced.

The word biotin comes from the Greek word “biote + in”, which means life or way of life.

 

Summary:

Vitamin B7, also called biotin, is an important essential vitamin for a proper function in the enzyme metabolism in providing us with high amounts of energy out of protein, fat and carbohydrates and it helps to promote a healthy skin, strong nails and shiny hair. Yeast, seeds, nuts, oat and egg yellow are good sources for your daily amount of vitamin B7.
