Vitamin C 1000mg
1000mg sounds impressive but your body absorbs only about 50% at this dose versus 90% at 200mg. You're making expensive urine. Nature Made's own 500mg version taken twice daily delivers more actual vitamin C. Sometimes less is literally more.
7.5/10
VERY GOOD1000mg Vitamin C is at the diminishing returns point. Absorption efficiency drops significantly above 200mg per single dose. The ingredient scores a 10, and 1000mg is safe and within the tolerable upper limit. It works, but their 500mg version is more efficient. Not wrong, just not optimal for absorption.
