Vitamin C
别名: ascorbic acid
Vitamin C is a water-soluble antioxidant needed for immunity, collagen formation and iron absorption. Humans cannot make it, but a varied diet with vegetables and fruit usually covers it.
用途
- Normal immune function and collagen formation – strong evidence (EFSA)
- Better absorption of iron from plant foods – strong evidence (EFSA)
- Shorter colds with regular use – moderate evidence, small effect; weak evidence when started only once ill
- Reduction of tiredness – EFSA-approved claim when intake is low
剂型及区别
ascorbic acid
standard, inexpensive form, high doses may irritate the stomach
sodium or calcium ascorbate (buffered)
gentler on the stomach
liposomal
slightly better absorbed but more expensive; practical benefit is unclear
powder
easy to dose into a drink
适合搭配
Iron (improves its absorption), zinc.
不宜同服 / 需错开
Do not take high doses at the same time as copper supplements.
注意事项
Take care if you are prone to kidney stones, have kidney disease or haemochromatosis. If you take medicines (e.g. chemotherapy), consult your doctor.
安全性
EFSA has not set an upper limit; doses above 1 g/day may cause diarrhoea and raise kidney stone risk in susceptible people. Do not exceed the label dose.
实用建议
For everyday needs 100–200 mg a day is enough; peppers, broccoli or kiwi easily cover it.
