Document Summary
Rate and extent in which a nutrient is absorbed and used by the body. Primary excretory route for water-soluble vitamins is the kidney. Other foods consumed at the same time. Inactive forms of vitamins (converted to active form in the body) (betacarotyne is a precursor for vitamin a) Organic (can be destroyed during storage or cooking) Toxicity (more is not necessarily better, levels higher than ul) Without b vitamins, the body would lack energy (help body use macronutrients for fuel) Rdas (niocin, collate, vitamin b6, b12, vitamin c) (only niocin, collate, vitamin c, vitamin b6 have ul) Recommendation- based primarily on its role in enzyme activity. Nicotinamide (major form of niacin in blood) Nicotinamide adenine dinucleotide (nad) (carries hydrogen and their electrons) 60mg of dietary tryptophan is needed to make 1mg of niacin. Only occurs after protein synthesis needs have been met. Potential health benefits from high dose of niacin (raises hdl, protects heart, lowers cholesterol and triglycerides)
