國人膳食營養素參考攝取量 (DRI)編輯

The Dietary Reference Intake (DRI)(from 20160327wikipedia) is a system of nutrition recommendations from the Institute of Medicine (IOM) of the National Academies (United States).[1]

Vitamins and minerals編輯

EARs, RDA/AIs and ULs for an average healthy 44-year-old male are shown below. Amounts and "ND" status for other age and gender groups, pregnant women, lactating women, and breastfeeding infants may be much different.[2]

• "NE": EARs have not yet been established or not yet evaluated.

• "ND": ULs could not be determined, and it is recommended that intake from these nutrients be from food only, to prevent adverse effects.

脂溶性維生素編輯

看起來脂溶性維生素目前似乎都會有致癌的危險,那尚未發現致癌風險的維生素D是否也只是尚未被發現?考慮維生素D的PK,其實是照光15分鐘左右完以後就足夠,然後會以負回饋機制防止過量,的確是短時間吸收完需要的分量,不像是體外補充A或是E都是短時間大量吸收和正常的PK由食物中緩慢吸收不同。或許維生素D雖然是脂溶性維生素但是不會有不良的影響,只要不要過量。?

要補充B群、C和D(但是要注意劑量),維生素A的輛反而要少。(要注意劑量)(天天吞綜合維他命 小心腎病失控)
