Yes, D3 is miraculous. I hope MetMom can find a way to up hers. If not lying nearly naked in the sun, then maybe the clear tiny drops that have no added cr@p in them. They have 2000 units per tiny drop. But not sure she can take anything by mouth, so it might have to be sun exposure.
We take 5,000 unit drops/day. WHen dad was on the GJ Tube, we opened them up and put them in the feeding tube. Don’t know how/if they taste.
