Biotin is a vitamin B,is essential for human nutrition

Biotin
Biotin Vitamin, a member of the B-vitamin family, is an essential nutrient in
human nutrition. It is involved in the biosynthesis of fatty acids,
gluconeogenesis, and energy production, the metabolism of the branched-chain
amino acids (L-Lucien, L-isoleucine, and L-valine) and the de novo synthesis of
purine nucleotides. Recent research indicates that biotin supplements plays a
role in gene expression, both at the transcriptional and translational levels,
and that it may also play a role in DNA replication.
Biotin Vitamin, also known as vitamin H, is of great importance for the
biochemistry of the human organism. As a prosthetic group of mitochondrial
enzymes (carboylases), biotin supplements plays a central role as a CO2-carrier
in important metabolic reactions such as gluconeogenesis, synthesis of fatty
acids and metabolism of amino acids. Furthermore, biotin nutrition influences
the growth and maintenance of blood cells, sebaceous glands, skin, hair and
nails. Next to the free form of biotin vitamin, the biotin linked to lysine,
also known as biocytine, can also be utilized as a vitamin source by the body,
after cleavage from the protein by the enzyme biotinidase.
Biotin Vitamin, as referred to as Vitamin H is part of the Vitamin B complex
group and might be interesting to some people since one of the most visible
symptoms of shortage of this vitamin is thinning of hair which can lead to total
hair loss.
Biotin supplements helps your body process the foods you eat, especially fats,
into glucose energy the cells can use. It is important for fat production and
synthesis of fatty acids. It helps to incorporate amino acids into protein and
is involved in DNA and RNA (the genetic material in cell nuclei) synthesis.
Food sources
Biotin Vitamin is present in cheese, beef liver, cauliflower, eggs, mushrooms,
chicken breasts, salmon, spinach, brewer's yeast, nuts and can be manufactured
in the body should a small shortfall occur. Good dietary sources of biotin
include organ meats, oatmeal, egg yolk, bananas, peanuts, and brewer's yeast.
What does biotin do for you?
Biotin supplements enables your body to process the fats, carbohydrates and
proteins into energy that its cells can use. Biotin plays an important role in
the production of the fatty acids that ensure healthy hair, skin and nerves.
It's even said to help prevent hair turning grey
How much biotin do you need?
The current RDA is 150–300 mcg, which is easily met by eating a balanced, mixed
diet and by using a combination B-complex vitamin supplement.
What is the function of biotin?
Energy Production
Biotin Vitamin is involved in the metabolism of both sugar and fat. In sugar
metabolism, biotin helps move sugar from its initial stages of processing on to
its conversion into usable chemical energy. For this reason, muscle cramps and
pains related to physical exertion, which may be the result of the body's
inability to use sugar efficiently as fuel, may signal a biotin deficiency.
Synthesis of Fat (Fatty Acids)
Many of the classic biotin supplements deficiency symptoms involve skin-related
problems, and the role of biotin nutrition in fat synthesis is often cited as a
reason for this biotin-skin link. Biotin Vitamin is required for function of an
enzyme in the body called acetyl Co-A carboxylase. This enzyme puts together the
building blocks for the production of fat in the body. Fat production is
critical for all cells in the body since the membranes of all cells must contain
the correct fat components to function properly.
Support of Nervous System Activity
Because glucose and fat are used for energy within the nervous system, biotin
Supplements also functions as a supportive vitamin in this area. Numerous
nerve-related symptoms have been linked to biotin deficiency. These symptoms
include seizures, lack of muscle coordination (ataxia), and lack of good muscle
tone (hypotonia).
What health conditions require special emphasis on biotin?
Biotin may play a role in the prevention and/or treatment of the following
health conditions:
• Hair loss (alopecia)
• Intestinal imbalances, including inflammatory bowel syndrome, irritable bowel
syndrome, Crohn's disease, ulcerative colitis, and chronic diarrhea
• Neuromuscular-related conditions, including seizures, ataxias (movements
characterized by lack of muscle coordination), and hypotonias (posture and
movement characterized by lack of muscle tone)
• Skin conditions, including cradle cap in infants and seborrheic dermatitis in
adults
• Pregnancy, as there is an increased demand for nutrients placed upon the
mother by the growing fetus.
Best used with
Biotin supplements should be taken with the B-group vitamins, but Vitamin C,
Vitamin B 5 (pantothenic acid), Vitamin B12 and sulfur are good companions to
it. A tricologist will sometimes add biotin to the diet of a patient suffering
from alopecia, to help with severe hair loss, but it must be in the right
quantities to satisfy the inter-dependence of other nutrients
