D-Biotin Vitamin B7

What is Biotin (Vitamin B7)?

Biotin is a water-soluble B vitamin, also called vitamin B7 and formerly known as vitamin H or coenzyme R.

Biotin is essential for the synthesis of vitamin C and is an essential substance for normal metabolism of fats and proteins. Biotin can be found in all living cells. It is a nutrient to maintain the body’s natural growth, development and normal body functions.

Biotin is also required for the catabolism and utilization of the three branched-chain amino acids: leucineisoleucine, and valine.

What’s the role of Biotin (Vitamin B7)

The human body needs about 100 to 300 mg D-Biotin per day. In raw egg white, there is an avidin protein (avidin) that binds with D-Biotin, and the combined D-Biotin cannot be absorbed by the digestive tract which will lead to the deficiency of D-Biotin in the animal body, that results in loss of appetite, glossitis, dermatitis, hair loss and so on.

However, the deficiency of D-Biotin have not yet be noticed in human beings, probably due to the fact that we intake foods high in Biotin or Biotin food sources; and intestinal bacteria can also synthesize D-Biotin. Biotin is a coenzyme of various enzymes in the human body, the role of Biotin involved in the metabolism of fatty acids and carbohydrates in the body; promoting the synthesis of proteins; also involved in the metabolism of vitamin B12, folic acid, pantothenic acid; and promoting urea synthesis and excretion.

Role of Biotin (Vitamin B7) and what it do?

  • Fat metabolism: help fat, liver sugar and amino acids in the human body for normal synthesis and metabolism;
  • Growth: promote the normal operation and growth of sweat glands, nerve tissue, bone marrow, male gonad, skin and hair, reduce eczema, dermatitis symptoms;
  • Prevent:  Biotin prevent white hair and hair loss, help to treat baldness;
  • Ease muscle pain;
  • Promote urea synthesis and excretion, purine synthesis and oleic acid biosynthesis.
  • Treatment: help treatment of arteriosclerosis, stroke, lipid metabolism disorders, hypertension, coronary heart disease and blood circulation disorders.

Is Biotin (Vitamin B7) natural?

Biotin can be found in food, the type of Biotin is natural. Actually there are eight different forms of Biotin, but only one is naturally occurring — the kind found in food sources. This type is called “D-biotin” and is believed to be the only type that has full vitamin capabilities.

How many Types of Biotin (As raw material) in the market?

Depends on Biotin is food grade or feed grade or pharmaceutical grade, commonly in the market the types of Biotin are: 1%, 2%, 10% and pure as raw material. As a D-Biotin manufacturer and supplier, we sell the main types in the market:

  • 2% D-Biotin feed grade (Maltodextrin as carrier)
  • 1% D-Biotin feed grade (Dicalcium Phosphate as carrier)

How is Biotin (Vitamin B7) absorption in body?

By oral intake, Biotin is quickly absorbed from the stomach and intestine. 80% of the Biotin in the blood is present in free form. It is distributed throughout tissues of the body and the content will be more in the liver and kidneys. It is excreted through the urine and only a little quantity is metabolized to Biotin oxides and double-lowering biotin.

What is (Vitamin B7) Biotin deficiency?

Biotin deficiency means the low biotin intake, and the deficiency symptoms would be as follows:

  • increase the risk of dandruff, easy hair loss, juvenile white hair;
  • dull complexion, blush, dermatitis;
  • depression, insomnia, easy to sleep and other neurological symptoms;
  • fatigue, lazy weakness, muscle pain.
    Signs of biotin deficiency: including dermatitis, eczema, atrophic glossitis, hyperesthesia, muscle pain, burnout, anorexia and mild anemia, hair loss

What is D-Biotin (Vitamin B7)

There are eight different forms of Biotin, but only D-Biotin is naturally occurring found in food sources. D-biotin is believed to be the only type that has full vitamin capabilities. The form of Biotin that your body can use is D-biotin.

The D, refers to chirality. Two molecules that are chiral isomers of each other will have the same chemical formula and structure; the only difference is the arrangement of groups around certain carbon atoms. It’s often easiest to think of chirality as “handedness”, so your left and right hands are chiral isomers of each other. Same structure, mirror images. Chirality does cause some difference in function.

Whenever you see “Biotin” in the supplement label or website or other place, it’s commonly means D-biotin. And the Biotin we talk in this article is D-Biotin which has full vitamin capabilities.

It is a B Vitamin, other B vitamins are Vitamin B1 (Thiamine Hcl), Vitamin B2 (Riboflavin), Vitamin B3 (Niacin, Niacinamide), Vitamin B5 (Pantothenic acid), Vitamin B6 (Pyridoxine Hydrochloride), Vitamin B9 (Folic acid) and Vitamin B12 (Cyanocobalamin).

Vitamin B7 D-Biotin Use

In Food

D-Biotin can be used in many dietary supplements, infant milk formulas and baby foods – as well as various dietetic products. D-Biotin is often used in combinations of the B vitamins. It can be used for human nutrition fortification, used for solid preparation, suitable for dry infusion with water.

What is biotin used for in the body?

Why do people take D-Biotin? Biotin can be used for promoting the synthesis of certain proteins by helping the production of energy; at the same time, it can help cells grow, produce fatty acids, metabolize carbohydrates, fats and proteins, and help the use of vitamin B; promoting sweat glands, nerve tissue, The health of bone marrow and male gonads maintains the normal operation and growth of skin and hair, relieves eczema and dermatitis symptoms, prevents white hair and hair loss, helps to treat baldness, eases muscle pain, and definitely helps melancholia and insomnia. Participate in the metabolism of vitamin B12, folic acid, pantothenic acid; promote urea synthesis and excretion; improve the body’s immune function.

In Cosmetics

D-Biotin market for cosmetics is developing and the beauty and cosmetics industry is one of the major international industries. As a D-Biotin manufacturer and supplier, our customers are mainly in the field of cosmetics and feed.

D-Biotin has an excellent cosmetic effect, it can keep skin white and nails smooth. The total international sales of cosmetics and cosmetics related products are much higher than the sales of pharmaceuticals. New applications of biotin in the skin, nails and hairdressing will inevitably lead to pharmaceutical-grade organisms.
D-Biotin as a nutritional supplement, can be used as a B Vitamin in the food industry. It has the function of preventing skin diseases and promoting lipid metabolism in cosmetics use.

It can increase the blood circulation speed in skin blood vessels. It is easy to mix the oil phase in the formula with concentration range from 0.1% to 1.0%. It can be used in skin creams, sports liquids, foot antiperspirants, shave lotions and shampoos in cosmetics use.

In Feed

D-Biotin is one of the B vitamins necessary to maintain normal physiological functions in the animal’s body. D- Biotin can be widely seen in feed additives plus animal intestines can synthesize D-Biotin, it was previously thought that it’s okay if animals feed do not add D-Biotin. However, D-Biotin deficiency often occurs especially under intensive production conditions, and D-biotin deficiency symptoms are more likely to occur.

The deficiency of D-biotin in livestock and poultry results in slow growth, reduced feeding, decreased breeding performance of female animals, and meat quality as well.  Carcass week, dermatitis, and even death will also happen. The intake of D-biotin can improve the above symptoms. As a result, people re-emphasize and study the nutritional effects of D-biotin and its mechanisms. In recent years, D-biotin has become one of the most popular water-soluble B vitamins.

D-Biotin Properties

d-Biotin can be found in plants and animals, and naturally occurring D-biotin exists mainly in combination with other molecules. Its chemical structure includes a carboxyl side chain containing five carbon atoms and two five-membered heterocycles, which binds to the ε-lysine residue of the enzyme protein in the body and acts as a coenzyme. Biotin may have 8 different isomers, of which only D-biotin has biological activity. In animals, cells often exist in the free state or in combination with proteins.

D-biotin nutrition mechanism

D-Biotin has both bound and free forms. The bound biotin cannot be used directly by the animal and must be decomposed by the biotin-degrading enzymes of the intestine to release free biotin before it can be used by animals. Biotin is well absorbed in the small intestine and is absorbed in intact molecules in the 1/3 to 1/2 segments of the small intestine. The porcine stomach cannot absorb biotin, the small intestine is the main site of absorption, and the colon can also absorb biotin, while chickens absorb biotin mainly in the small intestine. Almost all cells have biotin and the content in the liver and kidneys is relatively high.

The content of biotin is related to the biochemical effects of cells. Isotope markers indicated that the content of biotin in the proximal epithelial cells, hepatocytes, intestinal villus epithelial cells, and adipocytes of the kidneys is high, while the contents in some rapidly proliferating cells such as renal cortical cells, bone marrow cells, and lymphocytes are low. When pigs are fed diets supplemented with biotin, the concentration of biotin will increase in the liver, kidneys and heart. When the D-biotin intake is more than necessary, the exceeded will are excreted through the urine. Unabsorbed biotin in feed will be discharged from feces.

D-biotin Function

D-Biotin is a coenzyme component of sacetyl-CoA carboxylase, pyruvate carboxylase, propionyl-CoA carboxylase, and 3-methylcrotonyl-CoA carboxylase four carboxylase. It also play an important role in glucose, amino acid and fatty acid metabolism in animals, like in human beings.

D-Biotin and Carbohydrates metabolism: In gluconeogenesis, pyruvate carboxylase, which uses biotin as a coenzyme, is a key enzyme in pyruvic acid to produce butanion acid. Therefore, when the supplement of D-Biotin in the feed is insufficient, the glycogen will be quickly depleted or reduced, and hypoglycemia will occur. Especially, the glycogen stores in the chicks are relatively small and often leads to death.

D-Biotin and fat metabolism: In the process of fat metabolism, biotin acts as a coenzyme for acetyl-CoA carboxylase and catalyzes the formation of malonyl-CoA from acetyl-CoA. In the deficiency of biotin, abnormal lipid metabolism results in changes in the body’s fatty acid composition, reduced synthesis of saturated fatty acids, and increased synthesis of triacylglycerols, resulting in significant increases in lipids in the liver and kidneys.

Biotin and proteins, nucleic acids metabolism: biotin plays an important role in protein synthesis, amino acid decarboxylation, purine synthesis, carbamoyl transfer, and leucine and tryptophan catabolism, and is also required for the transfer and decarboxylation of many amino acids. Biotin not only participates in the carboxylase metabolic pathway, but also affects gene expression. The deficiency of biotin in animals will lead to slow cell proliferation, impaired immune function, and abnormal embryonic development.

How much D-Biotin is safe?

The recommended daily intake of Biotin is 30 micrograms (0.03 mg). For most individuals, supplementation is not necessary to avoid deficiency as biotin is found in most commonly natural foods.

However, biotin supplementation in large doses, sometimes over 50 times the recommended daily intake, is very popular to support hair, nail and skin growth. While evidence is mixed regarding just how well biotin works in this regard, studies show that biotin is extremely safe, even in large doses, and is unlikely to cause serious adverse events.

How much D-Biotin daily for hair growth?

Keratin is a basic protein that makes up your hair, skin, and nails. It’s clear that biotin improves your body’s keratin infrastructure. But beyond that, researchers aren’t really sure what biotin’s role in hair or skincare is.

Research on the effects of biotin on hair growth is sparse. To date, there’s only limited evidence to suggest that increased biotin intake may help promote hair growth.

How much D-Biotin should i take for hair loss?

The current recommended dosage of Biotin in Europe is set at 50 mcg/day. And how much Biotin should you take for hair growth may be some sort of a confusion regarding reference values because Europe and the USA have different numbers. The average intake from foods that contain Biotin in most western populations is about 35–70 mcg/day, showing that most people in these countries consume sufficient amounts of Biotin.

Biotin is a popular supplement for hair, skin, and fingernails, though there is little evidence to suggest that taking biotin supplements can stop hair loss or stimulate hair or nail growth. Similarly, using biotin shampoo or other hair products is unlikely to produce any benefit. There is some evidence that taking biotin supplements with other medications may help control hair loss that’s associated with childhood alopecia.
