2000 is per day is like nothing

I take 50,000iu per day for other things

50,00 is is 1.2 milligrams or about 1/1000 of the dose of vitamin c

Pregnant women in the 1940’s were given 1 million in per day for 9 months with no side effects

Look up vitamin D on PubMed

do not take massive amts of anything including vitamins until you at least talk to your doctor.....

I am familiar with all that. The problem is that 2,000 to 5,000 i.u. per day marks the limit of my capacity for shingles pain.
