SAFE and ADVISABLE: The recommended daily intake is the amount that will prevent obvious deficiency symptoms in most healthy people. They have nothing to do with the optimal levels for maintaining good health and preventing disease. See http://blissfulwriter.Hubpages.Com/hub/recommended-dietary-allowance-rda-is-too-low for example, the rdi of vit d is 600 iu/day but most adults need 5-8000 iu/day for optimal levels.
