Choline (from rice fiber and rice bran)

Choline is a nutrient related to the water-soluble B-complex vitamins that is necessary for the structure and function of all cells. It is important for the structural integrity of cell membranes and proper functioning of the brain, as well as required for a number of metabolic reactions that take place in the body. Humans can synthesize choline themselves, or they can consume choline through the diet. It can be found in high amounts in foods such as egg yolk, peanuts, fish, milk and a variety of meats and vegetables. Dietary choline is absorbed from the small intestine and travels through the bloodstream to all organs and tissues of the body. No adverse effects have been seen with choline intakes at the amounts present in our products 1.

Rice fiber is the soluble and insoluble fiber obtained from the bran layer of the rice kernel.

Rice bran is made from the bran layer, underneath the hull layer, of rice, Oryza sativa. Rice bran is high in dietary fiber, and is an excellent source of protein, vitamin E, thiamin, niacin, vitamin B6, pantothenic acid and a number of minerals, such as iron and magnesium. It is also a good source of folate and riboflavin 2. Rice bran also contains beta-sitosterol and other phytosterols, along with the essential omega-3 fatty acid alpha-linolenic acid (ALA) 3.
