Sounds like way too much; recommended is 400-800 units per day. Vitamin K2+D3 (one pill) is better.
It seems that many(most?) people talk about “how much” vitamin D they take. This is nonsense.
The important issue is not how much we take, but how much we have in our blood. Unless you have your blood checked for vitamin D you have absolutely NO IDEA whether you are deficient or not.
And, another thing—the optimal blood level for vitamin D is actually quite a bit higher than the “recommended” level. Don’t be afraid of vitamin D supplements. Do some research and you will learn that overdosing on this vitamin is almost impossible, and has seldom ever been reported—even with enormous supplement intake.
Take this for what it is worth, but you need to know that an optimal vitamin level is absolutely necessary if you want to be healthy.
(The writer is 80 years old, seldom, if never sick, and has been taking thousands of IU of vitamin D3 for many years.)
I also argue that there is a vitamin d mania on Free Republic. People take too much and want a blood level higher than is possible with sun exposure. I made many posts about it, some this month.
