Beetroots are rich in the nutrient betaine, which is important for cardiovascular health. It functions by acting with other nutrients to reduce the concentration of homocysteine, a homologue of the naturally occurring amino acid cysteine, which can be harmful to blood vessels and thus contribute to the development of heart disease, stroke, and peripheral vascular disease. Betaine functions in conjunction with S-adenosylmethionine, folic acid, and vitamins B6 and B2 in order to carry out this function. No preservatives
