I tried many types of vitamin D, and also without any addictives. I can take vitamin D2, but not vitamin D3.
So, it seems to understand that also sunbeds with UVB are unsafe.
But... what can be the reason Vitamin D3 trigger my IBS and not Vitamin D2? Also, salmon DO NOT trigger symptoms, even if it contains vitamin D3.
Might it contains additives even if the box just says "vitamin D3" as the only ingredient? There can be a difference in the synthetic formulation?
