Jarrow Ultra Policosanols, rice Policosanols are a family of aliphatic (non-ring) alcohols that have diverse beneficial effects. The original Japanese research was based on rice wax policosanols. The main policosanols are Octacosanol, Triacontanol, Dotriacontanol, Tetracosanol, Hexacosanol, Tetratriacontanol, Hexatriacontanol and Docosanol. Rice is the richest source of Docosanol. Animal experiments have shown policosanols improve cholesterol metabolism and reduce circulating triglycerides.

Octacosanol has been studied for its effects on improving physical performance and reducing fatigue.

Triacontanol is an alcohol. It is a naturally occuring plant hormone that promotes and regulates growth. Triacontanol can be found in plant cuticle wax and beeswax.

Docosanol protects the prostate gland and is considered a primary active component of the herb Pygeum africanum, which is used to maintain prostate health.

Tetracosanol is a policosanol, a mixture of alcohols. Policosanol is refined from the form of waxes found in sources such as sugar cane, rice bran, beeswax,broccoli, spinach, alfalfa and oats

Hexacosanol may have neuroprotective activity and neurotrophic activity, and it may increase phagocytic activity of macrophages.

Lecithin protects cells from oxidation and largely comprises the protective sheaths surrounding the brain. It is composed mostly of B vitamins, phosphoric acid, choline, linoleic acid and inositol. Although it is a fatty substance, it is also a fat emulsifier. Hence, it supports the circulatory system.

Medium-chain triglycerides are a class of fatty acids. Their chemical composition is of a shorter length than the long-chain fatty acids present in most other fats and oils, which accounts for their name. They are also different from other fats in that they have a slightly lower calorie content1 and they are more rapidly absorbed and burned as energy, resembling carbohydrate more than fat.
