Vitamin D - 6,000 IUs per day? 10,000 IUs???

My study indicates that there are toxic effects that set in above 5,000 IUs.

Mind you, this is using vitamin D by pill. From skin exposure to sun light, there are no known toxic effects, and thus - apart from sunburn and obviously cancer risk - no maximum dose.

I haven't looked it up in a while, but I believe the risk is to your liver and kidneys.

On the other side, I have only read of 3,000 IUs as a maximum used by researchers on Vitamin D who supplement their own dosage, seeking to maximize its pro-health effects.

Therefore, my dosing is 1,000 in the summer months, 2,000 IUs in the rest of the year, even in sunny Colorado (yes, sunnier than Miami and San Diego).

I've been taking 10k IUs every day for over a year now. Bloodwork confirms my vitamin D levels are within normal range after chronically being subpar for years.

Don't listen to those studies. Go to your GP and get the bloodwork, add or decrease the dosage as needed, and request more bloodwork. When it's all normal, stick with that dosage.

Hey, I can't argue with blood work. (Others, though, going and self-supplementing without it are fore warned - you may or may not be an exception!)

Agreed, start at 5k IUs and see where you end up. Just be mindful of any strange symptoms popping up when supplementing
