Looking into vitamin C one more time

Linus Pauling brought vitamin C to the world’s attention

Vitamin C has been repeatedly investigated since Linus Pauling focused on vitamin C. TET enzymes and JmjC domain-containing proteins are vitamin C and iron dependent enzymes which demethylate DNA and histones respectively. .Vitamin C is being investigated as a way to reprogram the epigenome..

There are various difficulties with supplementation with vitamin C. First of all vitamin C is poorly absorbed. Secondly vitamin C can affect mineral absorption. The adverse affects on mineral absorption of vitamin C has not been sufficiently stressed as an important limiting factor in vitamin C supplementation. As iron must be available in the gut forming vitamin C-iron complexes in the gut may not be desirable.

Getting vitamin C to work could be as easy as not taking trace minerals such as iron and copper at the same time as vitamin C. What one would be looking for is whether activity of TET enzymes and JmjC domain-containing proteins could be be increased by supplemental vitamin C and carbonyl iron taken at different times of the day. Activity of TET enzymes and JmjC domain-containing proteins in the gut would be investigated. A combination of immediate release vitamin C and liposomal vitamin C where the vitamin C is taken away from trace minerals could be optimal.
