- Fatty acidsα-Linolenic Acid2026.10.13
Alpha-linolenic acid, together with linoleic acid, is an essential fatty acid that the body cannot make, and each is converted into other fatty acids that serve many functions, such as brain and vision development and maintaining skin and reproductive function.
- Fatty acidsLinoleic Acid2026.10.13
Linoleic acid (an omega-6 fatty acid) and alpha-linolenic acid are essential fatty acids that the body cannot make, so they must be obtained from the diet.
- MineralsChloride2026.10.13
Chloride contributes to the body's charge balance and to the formation of stomach acid.
- MineralsPhosphorus2026.10.13
Phosphorus contributes to how cells use energy, regulation of the acid-base balance of body fluids, cell membrane structure, signaling in the body, and formation of hard tissues, among other things.
- Other nutrientsCholine2026.10.13
Choline is a core component of cell membrane phospholipids and an essential nutrient involved in methyl metabolism, acetylcholine synthesis, lipid transport, and signaling.
- MineralsMolybdenum2026.10.13
Molybdenum acts as a cofactor that helps body enzymes such as xanthine oxidase do their work, and it takes part in the making of uric acid.
- Fatty acidsEicosapentaenoic acid, Docosahexaenoic acid (EPA, DHA)2026.10.13
DHA is a component of the membrane lipids of the cerebral cortex, and omega-3 fatty acids are especially abundant in nerve cells and the retina.
- VitaminsVitamin K2026.10.13
Vitamin K is involved in helping blood clotting proteins (clotting factors) do their job so that blood can clot.
- MineralsIodine2026.10.13
Iodine is an essential trace element and a main component of thyroid hormones.
- MineralsCopper2026.10.13
Copper is a trace mineral that is essential for many enzyme reactions and physiological functions in the body.
- Other nutrientsTotal Fiber2026.10.13
Soluble fiber forms a gel in the gut and slows the absorption of cholesterol and glucose, and insoluble fiber adds bulk in the gut and helps the bowel move.
- Other nutrientsProtein2026.10.13
Protein supplies the amino acids and nitrogen compounds needed for normal growth and maintenance of the body, and is also used as a source of energy.
- MineralsChromium2026.10.13
Chromium is known to play an important role in controlling blood sugar and maintaining insulin sensitivity.
- MineralsManganese2026.10.13
Manganese is a component of many enzymes, and through the activity of these enzymes it is involved in antioxidant reactions, nutrient metabolism, bone formation, blood clotting, blood sugar regulation, synthesis of sex hormones and nucleic acids, and immune responses.
- MineralsPotassium2026.10.13
Potassium is an electrolyte that is essential for body functions such as water and electrolyte balance, nerve impulse transmission, muscle contraction, and blood pressure control.
- VitaminsBiotin2026.10.13
Biotin acts as a coenzyme for four enzymes essential to mammalian cell metabolism.
- MineralsSelenium2026.10.13
Selenium is present in the body in only tiny amounts, but it is an essential nutrient for powerful antioxidant action, thyroid hormone metabolism, immune function, and reproductive function.
- VitaminsFolate2026.10.13
Folate has essential roles in the body in DNA synthesis, amino acid metabolism, and cell division, and it is especially important in early pregnancy for the formation of the baby's neural tube.
- MineralsSodium2026.10.13
Sodium takes part in nerve transmission, muscle contraction, and the cotransport of glucose and amino acids with sodium in the small intestine.
- VitaminsPantothenic Acid2026.10.13
In the body, pantothenic acid is a central precursor of coenzyme A and plays an essential coenzyme role in major metabolic processes, including glycolysis, the TCA cycle, fatty acid beta-oxidation, and lipid metabolism. It is also involved in the synthesis of fatty acids, phospholipids, steroid hormones, vitamin D, the porphyrin component of hemoglobin, and the neurotransmitter acetylcholine, playing an important role in regulating cell metabolism and maintaining health.
- VitaminsRiboflavin2026.10.13
Riboflavin takes part in energy metabolism, cell function, growth and development, and the metabolism of lipids, steroids, and drugs.
- VitaminsVitamin E2026.10.13
Vitamin E is a main part of the body's antioxidant defense system, and it works to remove peroxyl radicals.
- VitaminsThiamin2026.10.13
Most thiamin in the body is in the form of thiamin pyrophosphate, a coenzyme, and it plays a key role in carbohydrate metabolism and more.
- VitaminsNiacin2026.10.13
Niacin is converted into coenzymes in the body, takes part in oxidation-reduction reactions, and plays an important role especially in energy metabolism.
- VitaminsVitamin B122026.10.13
Vitamin B12 is a nutrient needed for red blood cells to form and mature, for the nervous system to work normally, and for making DNA.
- VitaminsVitamin B62026.10.13
Vitamin B6 acts as a coenzyme for a very large number of amino acid metabolism enzymes, and it is involved in lipid and carbohydrate metabolism, neurotransmitter synthesis, and more.
- MineralsZinc2026.10.13
