C What This Stuff Can Do.
Vitamin C is an essential nutrient—meaning your body requires it for physiological function but can't actually produce the stuff itself. So where's your body going to get it? We can help with that. Vit C is absorbed in the small intestine, has natural killer (NK) cell properties, and is a potent antioxidant. Its good work battling infection suggests C is a lead player in immune system health.

Later, vitamin C was found to help with iron absorption, fight oxidative stress, and bolster the immune system. Oh, and orange juice with breakfast? Smooth sailing.
