GranV™️ B vitamins help a variety of enzymes do their jobs, ranging from releasing energy from carbohydrates and fat to breaking down amino acids and transporting oxygen and energy-containing nutrients around the body. There are eight B vitamins
- B1 (thiamin)Thiamin (thiamine), or vitamin B1, is a water-soluble vitamin found naturally in some foods, added to foods, and sold as a supplement. Thiamin plays a vital role in the growth and function of various cells. Only small amounts are stored in the liver, so a daily intake of thiamin-rich foods is needed.Thiamin is involved in several basic cell functions and the breakdown of nutrients for energy, a deficiency can lead to various problems in the brain and heart that require a constant supply of energy.
- B2 (riboflavin)
Vitamin B2, or riboflavin, is naturally present in foods, added to foods, and available as a supplement. Bacteria in the gut can produce small amounts of riboflavin, but not enough to meet dietary needs. Riboflavin is a key component of coenzymes involved with the growth of cells, energy production, and the breakdown of fats, steroids, and medications. Most riboflavin is used immediately and not stored in the body, so excess amounts are excreted in the urine. An excess of dietary riboflavin, usually from supplements, can cause urine to become bright yellow. Riboflavin assists many enzymes with various daily functions throughout the body, a deficiency can lead to health problems. Animal studies show that the brain and heart disorders and some cancers can develop from long-term riboflavin deficiency.
- B3 (niacin)
Niacin, or vitamin B3, is a water-soluble B vitamin found naturally in some foods, added to foods, and sold as a supplement. The two most common forms of niacin in food and supplements are nicotinic acid and nicotinamide. The body can also convert tryptophan—an amino acid—to nicotinamide. Niacin is water-soluble so that excess amounts the body does not need are excreted in the urine. Niacin works in the body as a coenzyme, with more than 400 enzymes dependent on it for various reactions. Niacin helps to convert nutrients into energy, create cholesterol and fats, create and repair DNA, and exert antioxidant effects.
- B5 (pantothenic acid)
Vitamin B5, or pantothenic acid, is naturally present in foods, added to foods, and available as a supplement. It is used to make coenzyme A (CoA), a chemical compound that helps enzymes to build and break down fatty acids as well as perform other metabolic functions, and acyl carrier protein, which is also involved in building fats. Pantothenic acid is found in a wide variety of foods. Bacteria in the gut can also produce some pantothenic acid but not enough to meet dietary needs. Pantothenic acid helps to break down fats, it has been studied for a potential role in reducing cholesterol levels in people who have dyslipidemia.
- B6 (pyridoxine)
Vitamin B6, or pyridoxine, is a water-soluble vitamin found naturally in many foods, as well as added to foods and supplements. Pyridoxal 5’ phosphate (PLP) is the active coenzyme form and most common measure of B6 blood levels in the body. PLP is a coenzyme that assists more than 100 enzymes to perform various functions, including the breakdown of proteins, carbohydrates, and fats; maintaining normal levels of homocysteine (since high levels can cause heart problems); and supporting immune function and brain health.
- B7 (biotin)
Vitamin B7 is recognize by its popular name of biotin. It is a water-soluble B vitamin found naturally in some foods and also in supplements. Biotin plays a vital role in assisting enzymes to break down fats, carbohydrates, and proteins in food. It also helps to regulate signals sent by cells and the activity of genes. Biotin supplements are often glamorized as a treatment for hair loss and to promote healthy hair, skin, and nails.
- B9 (folate [folic acid])
Folate is the natural form of vitamin B9, water-soluble and naturally found in many foods. It is also added to foods and sold as a supplement in the form of folic acid; this form is actually better absorbed than that from food sources—85% vs. 50%, respectively. Folate helps to form DNA and RNA and is involved in protein metabolism. It plays a key role in breaking down homocysteine, an amino acid that can exert harmful effects in the body if it is present in high amounts. Folate is also needed to produce healthy red blood cells and is critical during periods of rapid growth, such as during pregnancy and fetal development.
- B12 (cobalamin)
Vitamin B12, or cobalamin, is naturally found in animal foods. It can also be added to foods or supplements. Vitamin B12 is needed to form red blood cells and DNA. It is also a key player in the function and development of brain and nerve cells.Vitamin B12 binds to the protein in the foods we eat. In the stomach, hydrochloric acid and enzymes unbind vitamin B12 into its free form. From there, vitamin B12 combines with a protein called intrinsic factor so that it can be absorbed further down in the small intestine.
