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.
6.0/10
GOOD1000mg vitamin C is above what most people need. Your body maxes out absorption around 200-400mg per dose. The excess gets excreted. Their 500mg version is actually the smarter buy.
