CAUTION FOR ASTHMA / LOW IRON - depletes other nutrients and *causes* asthma

Posted by Health-Is-Wealth on Dec 17, 2012 | Verified Purchase

Vit A increases transferrin - higher doses can be detrimental to anyone low in iron, asthmatics, etc. I do not recommend vit A in this dose because it is too effective - used regularly, it causes me to get breathless (in a very unpleasant way) and I end up having to supplement other things to compensate (when they're normally not necessary). Suggest limited/occasional use only. I want a natural vit A, however it seems impossible to find one in lower doses, especially one that isn't cod.
