提高VitD有3种方法:
1.晒太阳(Sunshine - the best source of vitamin D),但注意防晒;
2.食物;
3.from supplements.
只有足够的VitD,才能更好地帮助吸收牛奶或酸奶里的钙,减少osteoporosis的风险,尤其对中年女性.
我前年2010冬天也查出VitD低.家庭医生建议我吃1000IU.老实坦白,一开始我挺注意吃的,后来常常忘了.去年复查,刚好合格,医生还是让我接着吃,等一年后再测VitD水平.所以你不妨吃一段,只要不超过以下的最高限量(UL),应该是安全的.
The IOM's recommendations are summarized below:
| Age | Daily Vitamin D, in IUs | |||
| AI | EAR | RDA | UL | |
| 0-6 Mths | 400 | - | - | 1000 |
