D-Pantethine, also known as pantetina or pantomin, belongs to the class of organic compounds known as beta amino acids and derivatives. These are amino acids having a (-NH2) group attached to the beta carbon atom. Most vitamin B5 supplements are in the form of calcium pantothenate, a salt of pantothenic acid, with doses in the range of 5 to 10 mg/day. Pantethine is available in the United States as a dietary supplement because of evidence of its health benefits for lowering elevated LDL-cholesterol and triglycerides, and raising HDL-cholesterol (the good cholesterol). In contrast, pantethine is sold as a dietary supplement for lowering blood cholesterol and triglycerides at doses of 500 to 1200 mg/day. These clinical trials were conducted with daily intakes ranging from 600 to 1200 mg/day. Pantethine (bis-pantethine or co-enzyme pantethine) is a dimeric form of pantetheine, which is produced from pantothenic acid (vitamin B5) by the addition of cysteamine. D-Pantethine is a drug. Pantetheine is an intermediate in the production of coenzyme A by the body. In multiple clinical trials of patients with elevated cholesterol and triglycerides, total and LDL cholesterol were decreased by an average of 12\\\%, triglycerides decreased by 19\\\%, and HDL cholesterol was increased by 9\\\%. Pantethine is composed of two molecules of pantetheine linked by a bridging disulfide. Most of the literature on pantethine and lipids is 20 to 30 years old, but recent carefully controlled trials of 600 and 900 mg/d doses have shown similar statistically significant lowering of LDL cholesterol in individuals with greatly or moderately elevated levels of blood lipids. A few trials conducted in Japan tested 300 mg/day and reported decreases in total cholesterol of about 4\\\%, increases in HDL-cholesterol of 5\\\% and inconsistent results for triglycerides. Direct dose-response evidence is not available because no trial tested more than one dose. Within this dose range there is no evidence of a dose-effect relationship, i.e. changes in lipid concentrations overlapped across the range of doses. Pantethine (Bis-pantethine) or "Co-enzyme pantethine" is a dimeric form of vitamin B5, composed of two molecules of pantothenic acid linked by cysteamine bridging groups. The monomer of this compound is known as pantetheine and is an intermediate in the production of Coenzyme A by the body. Pantethine is considered the more biologically active form of vitamin B5, but is less stable than pantothenic acid and tends to decompose over time if it is not kept refrigerated, so most vitamin B5 supplements are in the form of calcium pantothenate.
