Yep, you’re a chem major. Did you minor in bio chem? or was your major biochem and minor BE (Bio engineering)
I mean, you could have done all the studying yourself but damn, talk about bored!!! Those books aren’t page turners!!!
Concentration of vitamin A was also found to be antagonist to vitamin D absorption (Aburto and Britton 1998). In addition, vitamin A also discriminates dietary D3 (coming from food) and endogenous D3 (synthesized in skin by action of sunlight) in their utilization i.e. negatively affect the utilization of dietary vitamin D3, but not the endogenous vitamin D3 (Johansson and Melhus 2001). Recently a research demonstrated that high concentration of vitamin A reduce bioavailability of vitamin D by 30%. However the mechanisms, how vitamin A hampers the vitamin D absorption, does remain unknown and requires further investigation.
Well, Vitamin A appears to be the only Vitamin considered to be essential for pulmonary function.
If Vitamin A (in some manners or forms) “antagonizes” Vitamin D absorption and/or metabolism, taking just a bit more Vitamin D would seem to be a rational way to cope.
I asked you about your (apparent) assertion that Vitamin D affects Vitamin C. Any clues ?
Sorry, I am not feeling well at all today - and you, sir, (ostensibly) enjoy the nerding-out (on this subject area) more than I do. I’m just a slobbering cretin, myself. …
