You have to be sure that the supplement vitamines don't come out of a laboratory. Studies has shown that for example an 'artificial' Vitamin C connects with the cell but don't enter. The place where this Vitamin C docked at the the cell forbid a 'natural' Vitamin to dock and enter into the cell.
Actually it isn't quiet clear if this is a permanent situation or how long the regeneration process will last. When you have a look, where Vitamin A plays a role, such as: * Vision * Gene transcription * Immune function * Embryonic development and reproduction * Bone metabolism * Haematopoiesis * Skin health * Antioxidant activityit's difficult to say, that it will increase mortality. But it's true that a lack of Vitamin A provoke blindness.
On the other side too much Vitamin A can lead to nausea, jaundice, irritability, anorexia (not to be confused with anorexia nervosa, the eating disorder), vomiting, blurry vision, headaches, hairloss, muscle and abdominal pain and weakness, drowsiness, and altered mental status. Hope this was a little bit helpful.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
