No issues. It's just that it's a powerful lipid-soluble vitamin–hormone that can be abused with high-doses. About 2,000 IUs should be great for 99% of people, but you do see very high doses for sale. Even 5,000 IUs can make my joints stiff at times.What do you see as the issues with D3 supplementation? You're not referring to Marshall are you?
Most of the B-vitamins can be chronically-consumed at 100× the RDA, for months, with very little side-effects.
This can even be absorbed transdermally. I bought magnesium chloride in a spray bottle, and a few sprays on the skin has noticeable effects. It is relaxing. You might not expect just a simple mineral to be so powerful, but it is. Everyone seems to be interested in acetylcholine and ATP, but muscle tension is even influenced by simple things such as magnesium and calcium. and they seem to somewhat antagonize each-other inside the cell.I think magnesium is a little hard and so I am told...
