What Are the Symptoms of a Biotin Overdose?

Biotin, also known as vitamin H and coenzyme R, is a water-soluble vitamin and also belongs to the vitamin B family, B7. It is an essential substance for the synthesis of vitamin C and is essential for the normal metabolism of fats and proteins. It is a nutrient necessary to maintain the natural growth, development and normal human health.

1. Constitutes light-sensing substances in the optic sink cells.

Biotin is oxidized in the body to produce cis-retinal and anti-retinal. There are two types of photoreceptor cells in the human retina, of which rod cells are sensitive to low light and are related to dark vision, because rod cells contain the light-sensitive substance rhodopsin, which is composed of egg cells and cis-retinal. When vitamin H deficiency, cis-retinal is not adequately supplemented, and rod cells cannot synthesize sufficient rhodopsin, which causes night blindness. ^[2]

The human body needs about 100 to 300 micrograms per day. There is an avidin protein (ovin, avidin) in raw egg white that can be combined with biotin, and the combined biotin cannot be absorbed by the digestive tract; resulting in a lack of biotin in the animal body. At this time, loss of appetite, glossitis, Dandruff dermatitis, hair removal, etc. However, no cases of human biotin deficiency have been seen, probably because intestinal bacteria can synthesize biotin in addition to food sources. Biotin is a coenzyme of various enzymes in the human body, participating in the metabolism of fatty acids and carbohydrates in the body; promoting the synthesis of proteins; also participating in the metabolism of vitamin B12, folic acid, pantothenic acid; promoting the synthesis and excretion of urea.

Help the normal synthesis and metabolism of fat, glycogen and amino acids in the human body;

Promote the normal operation and growth of sweat glands, nerve tissue, bone marrow, male gonads, skin and hair, and reduce symptoms of eczema and dermatitis;

Preventing white hair and hair loss helps to treat baldness;

Relieve muscle pain;

Promote urea synthesis and excretion, purine synthesis and oleic acid biosynthesis.

For the treatment of arteriosclerosis, stroke, lipid metabolism disorders, hypertension, coronary heart disease and disorders of blood circulation.

If biotin is used together with vitamin A, vitamin B2, vitamin B6, and niacin (vitamin B3), they will complement each other and have a better effect. Supplementation cycle: Vitamin H stays in the human body for only 3 to 6 hours, so it must be supplemented daily. ^[1]

Biotin, known as vitamin H, enables the body to convert food into its own energy. Biotin is good for cell health and regeneration.

1. Lack of biotin increases dandruff in humans, leading to hair loss and white hair in teenagers;

2. Lack of biotin will cause dull complexion, blue complexion and dermatitis;

3. Lack of biotin can easily lead to neurological symptoms such as depression, insomnia, and drowsiness;

4. Lack of biotin can cause fatigue, laziness, and muscle pain.

Signs of biotin deficiency: include dermatitis, eczema, atrophic glossitis, hypersensitivity, muscle pain, burnout, anorexia and mild anemia, hair loss. ^[2]

The toxicity of biotin seems to be very low, and the treatment of seborrheic dermatitis with large doses of biotin did not reveal abnormal protein metabolism or genetic errors and other metabolic abnormalities. Animal experiments have also shown that biotin is rarely toxic. ^[2]

Recommended daily intake: Adults recommend 25 to 300 g daily. Biotin works better with vitamins (vitamin foods) A, B 2, B 6 and niacin.

Supplement cycle: Vitamin B7 stays in the human body for only 3 to 6 hours, so it must be supplemented daily.

People in need: those who eat raw eggs and drink alcohol need biotin supplementation; those who take antibiotics or sulfa drugs should consume at least 25 g per day; men with thin hair (male food) consume biotin to prevent hair loss; During this period, biotin will be obviously lost and should be supplemented reasonably under the guidance of a physician.

Biotin (vitamin H) deficiency: The main manifestations of biotin (vitamin H) and biotin (vitamin H) deficiency are mostly skin symptoms, showing thinning hair, loss of gloss, dry skin, scaly dermatitis, red rash, In severe cases, the rash can persist around the eyes, nose, and mouth. In addition, it is accompanied by anorexia, nausea, vomiting, atrophy of the tongue and nipples, graying of the mucosa, numbness, depression, fatigue, myalgia,

Folic Acid (Folic Acid) Function: Makes red blood cells and white blood cells, and enhances immunity. Deficiency: redness and swelling of the tongue, anemia, indigestion, fatigue, graying of the hair, memory loss. Main food sources: vegetables, meat, yeast, etc.

Vitamin C (ascorbic acid) function: fight against free radicals, help prevent cancer; reduce cholesterol, strengthen the body's immunity, and prevent scurvy. Deficiency: bleeding gums, tooth loss; fragile capillaries, slow wound healing, subcutaneous bleeding, etc. Main food sources: fruits (especially oranges), green vegetables, tomatoes, potatoes, etc.

Vitamin D function: assist calcium transport, help children develop teeth and bones; supplement calcium needed for adult bones, and prevent osteoporosis Deficiency: children with osteomalacia, loss of appetite; diarrhea, etc. Main food sources: cod liver oil, dairy products, eggs.

Vitamin E (tocopherol) function: antioxidants, help prevent cancer; fertility related. Deficiency: damaged red blood cells, damaged nerves, trophic muscular atrophy, infertility, irregular menstruation, uterine function decline, etc. Main food sources: vegetable oil, dark green vegetables, milk, eggs, liver, wheat, and nuts. ^[2]
