Worth knowing about this bottle

Vitamin C and Vitamin E work better together

Vitamin C can regenerate vitamin E after it has neutralised a free radical, so in a test tube the two extend each other. In people the effect has been much harder to show: the one crossover trial to look directly found each vitamin nudged the other’s blood level, and nothing beyond that.
