What are you actually worried about from vitamin D?
As a natural source one small serving of fish will give you 100-200% of the RDA for vit D.
...and MD's are never wrong?
RESULTS: In spring, 60.3% of the women had 25(OH)D(3) <or=50 nmol/l, and the target of 75 nmol/l was reached by 9.1%. For supplement users, the respective numbers were 52.1 and 11.9%.
So the average Vit D supplement user had lower 25(OH)D(3) than those who did not supplement.
Supplemental D3 is probably also a metabolite and does not actually address the bodily needs of the parent compound (in the same way that DHA and EPA can not replace the functions of ALA/LA)
