Vitamin B7, more commonly known as biotin, is a water-soluble nutrient that is part of the B vitamin family. B vitamins help support adrenal function, help calm and maintain a healthy nervous system, and are necessary for key metabolic processes. Biotin is essential for the metabolism of carbohydrate and fat.
Functions and benefits of Vitamin B7
People with diabetes may find Biotin beneficial because it has been known to increase the body's reaction to insulin. It plays a role in energy metabolism, and has been used to treat alopecia, cancer, Crohn's disease, hair loss, Parkinson's disease, peripheral neuropathy, Rett syndrome, seborrheic dermatitis, and vaginal candidiasis.
Vitamin B7 has a number of important functions and benefits. For example it:
* It helps to relieve muscle pain. * Biotin helps in the synthesis of fatty acids * It helps in energy metabolism * Biotin helps in the synthesis of amino acids and glucose.
Recommended Dosage for Vitamin B7
Its estimated minimum daily requirement is between 30 mcg to 300 mcg for both man and women. In people without disorders of biotin metabolism, doses of up to 5 mg/day for two years were not associated with adverse effects.
Food sources of Vitamin B7
Biotin is found in many foods, but generally in lower amounts than other water-soluble vitamins. Natural sources of biotin include egg yolk, liver, kidney, cooked oats, soybeans, unpolished rice, brewer's yeast, nuts and milk. Egg whites contain a chemical that binds to biotin very strongly and prevents it being absorbed into the blood from the intestines.
Deficiency Symptoms of Vitamin B7
Vitamin B7can be induced in humans by feeding them raw egg whites, which contain a protein that binds biotin and prevents its absorption. Long-term antibiotic use can interfere with biotin production in the intestine and increase the risk of deficiency symptoms, such as dermatitis, depression, hair loss, anemia, and nausea. Long-term use of anti-seizure medications may also lead to biotin deficiency. Biotin deficiency results in fatigue, depression, nausea, muscle pains, hair loss, and anemia. Biotin is necessary for both metabolism and growth in humans, particularly with reference to production of fatty acids, antibodies, digestive enzymes, and in niacin metabolism.
Vitamin B9 is one of eight water-soluble B vitamins. All B vitamins help the body to convert carbohydrates into glucose, which is "burned" to produce energy. These B vitamins, often referred to as B complex vitamins, are essential in the breakdown of fats and protein. B complex vitamins also play an important role in maintaining muscle tone along the lining of the digestive tract and promoting the health of the nervous system, skin, hair, eyes, mouth, and liver.
Functions and benefits of Vitamin B9
Folic acid has played several important roles in the metabolic processes in the body. It is essential for the normal growth and maintenance of all cells because it acts as a coenzyme for normal DNA and RNA synthesis. Pregnant women who are thinking of becoming pregnant or who are pregnant often require additional supplementation of folic acid. Folic acid also assists in digestion, and the nervous system, and works at improving mental as well as emotional health. This nutrient may be effective in treating depression and anxiety. Folic acid may play an important role in prevention of certain cancers: lung, colon, and cervical. Synthetic folic acid supplements may be used in the treatment of disorders associated with folic acid deficiency and may also be part of the recommended treatment for certain menstrual problems and leg ulcers. People who are at high risk of strokes and heart disease may greatly benefit by taking folic acid supplements.
Recommended Dosage for Vitamin B9
For everyone whose are 11 years and older the Recommended Daily Allowance is 400 micrograms. Women need an additional 400 micrograms of folic acid each day during pregnancy, and an extra 100 micrograms while breastfeeding. Check with a medical professional before giving Vitamin B9 to an infant or child, or if prescription medication is taken regularly.
Food sources of Vitamin B9
Rich sources of folic acid are spinach, dark leafy greens, asparagus, turnip, beet and mustard greens, Brussels sprouts, salmon, orange juice, avocado, and milk, whole grains, wheat germ, bulgur wheat, kidney beans lima beans, soybeans, beef liver, brewer's yeast, root vegetables, , white beans and lima beans.
Deficiency Symptoms of Vitamin B9
A deficiency of folic acid limits cell function (cell division and protein synthesis) and affects the normal growth and repair of all cells and tissues in the body. The tissues that have the fastest rate of cell replacement are affected first.
