About The Vitamin D3 500

D-biotin is also often referred to as biotin. It is a water-soluble vitamin that plays an indispensable role in the physiological process of the human body. The following is a detailed introduction about it:

I. Basic Overview

Chemical Structure: The chemical structure of D-biotin is relatively unique. It is composed of a urea ring and a sulfur-containing tetrahydrothiophene ring. This specific structure gives it the corresponding biochemical properties and the basis for its role in the body.

Alias: It is also called vitamin H, coenzyme R, etc. Different names reflect the angle of its cognition in different physiological function research or application scenarios.

II. Food Sources

Animal liver: Animal liver is a very good source of biotin. For example, every 100 grams of chicken liver contains about 100-300 micrograms of biotin, which is relatively rich and has a high bioavailability.

Eggs: Eggs are one of the common foods rich in biotin, especially the yolk. Every 100 grams of egg yolk contains about 30-60 micrograms of biotin. Daily consumption of eggs can help the human body absorb a certain amount of this vitamin.

Milk and its products: Like milk, every 100 ml contains about 2-5 micrograms of biotin. Although the content is not particularly high, it is also a stable way for people who often drink dairy products to intake biotin.

Beans and some vegetables: For example, soybeans contain about 20-30 micrograms of biotin per 100 grams. In addition, vegetables such as broccoli and spinach also contain a small amount of biotin, which provides a certain food choice for vegetarians to supplement biotin.

III. Physiological function

Participate in carboxylation reaction: It is a coenzyme of various carboxylases in the body and plays a key role in carboxylation reaction. For example, in the process of gluconeogenesis, it participates in the reaction step of pyruvate carboxylation to oxaloacetate, which helps maintain the stability of blood sugar levels; in the process of fatty acid synthesis, it can help acetyl CoA carboxylation to malonyl CoA, which is very important for the anabolism of fat.

Maintaining healthy skin, hair and nails: Biotin is closely related to the normal structure and growth and development of skin, hair and nails. It can promote the synthesis of keratin, keep the skin healthy, and reduce the occurrence of problems such as rashes, dryness, and desquamation; for hair, it can enhance its toughness, reduce hair loss, and promote normal hair growth; for nails, it helps maintain the hardness and gloss of nails, and prevents the occurrence of brittle and easy breakage of nails.

Participating in the regulation of the nervous system: It plays a certain role in maintaining the normal function of the nervous system, helps the transmission of nerve signals and the normal metabolism of nerve cells. Although the specific mechanism is relatively complex, it has positive significance for the stability of overall cognitive, emotional and other neural functions.

IV. Deficiency and Excess Manifestations

Deficiency manifestations:

Skin problems: The most common is the appearance of a rash, which may be a small local red rash at first, and then develop into diffuse erythema and desquamation, which is more common in exposed parts such as the face, neck, and limbs, and may also be accompanied by skin itching.

Abnormal hair and nails: The hair becomes sparse, fragile, easy to break, and even hair loss occurs; the nails may become thinner, brittle, and lose their luster, which seriously affects the appearance and normal use.

Nervous system symptoms: Symptoms such as depression, drowsiness, hallucinations, and muscle pain may occur, which have a great impact on daily life and mental state.

Others: It may also cause digestive discomfort symptoms such as loss of appetite, nausea, and vomiting, affecting the normal intake and digestion and absorption of nutrients.

Excessive manifestations: Since biotin is a water-soluble vitamin, it is generally difficult to have an overdose through a normal diet. Even if additional supplements are taken, the excess will be excreted from the body with urine. However, in the rare case of excessive use of supplements and extremely high doses, some potential adverse effects such as metabolic disorders that have not yet been clearly identified may occur, but there are currently few accurate reports on this.

V. Applicable population and recommended intake

Applicable population:

Pregnant women and breastfeeding women: Their demand for biotin will increase during this special physiological period, because biotin is important for the growth and development of the fetus, especially the development of tissues such as skin and hair, as well as the maintenance of the mother’s own physiological functions, and adequate intake is required.

People who take antibiotics for a long time: Some antibiotics may affect the balance of normal intestinal flora, and intestinal flora can synthesize a certain amount of biotin. After long-term use of antibiotics, the synthesis of biotin may be disturbed. Such people are prone to biotin deficiency risks and should pay appropriate attention to supplementation.

People with skin, hair, and nail problems: For those who have rough skin, severe hair loss, and unhealthy nails due to various reasons, appropriate supplementation of biotin may help improve these conditions after excluding other disease factors.

Recommended intake: The recommended intake varies for different age groups and genders. For example, the recommended daily intake for adult men and women is generally about 30 micrograms, the recommended daily intake for pregnant women is about 30-35 micrograms, and the recommended daily intake for breastfeeding women is about 35 micrograms.

VI. Precautions

Influence of drugs and other substances: Certain drugs such as anti-epileptic drugs and avidin (present in raw egg white) can affect the absorption or utilization of biotin.
