That is a perfectly reasonable amount of vitamin D to take weekly. If taken orally not all of it will be absorbed anyway.
I was of the understanding that D3 is lipophillic to the extent that it would likely just be absorbed into and leeched from fat over time. I'm not well read on the literature
Before vitamin D can be stored in fat it must first be absorbed from the digestive system into the bloodstream. The absorbtion efficiency varies by individual but no one absorbs 100%. After making it into the blood some excess vitamin D can be stored in fat cells for later use.
So I safe?
