Knowledge expansion: matters needing attention in vitamin C supplementation
1. Vitamin C should be supplemented from food as much as possible, while artificial vitamin C is a pure pharmaceutical preparation, which is far less effective than natural vitamin C, and the amount of artificial preparation is often large, which can form oxalic acid in the body for a long time, which is a potential threat to the formation of stones. However, vitamin C in fruits and vegetables does not easily lead to high oxalic acid content in urine.
2. Supplement should not be excessive. According to 20 16 dietary guidelines for China residents, the recommended daily intake of vitamin c for women in the first trimester is 100㎎, and for women in the second and third trimesters is 1 15㎎, so as to meet the needs of mothers and fetuses.
