That seems to be almost too high. Vitamin D is fat soluble and you're taking way more than the RDA of 600 IU. Even at 6000 IU, which you suggest is optimal, you're taking 2x.

I'm not a doctor either but have you consulted your doctor about this (or is this a short time frame for you to get back up to a health level?).

It was actually my doctor who recommended this after a blood test showing I had a Vitamin D deficiency, and initially I was taking 15000 IU for a short period. I have been doing this for at least 6 months now with no ill affects, and many positives ones ( better mood, better sleep, better energy, etc...)

Do any testing of your Vit D blood levels after taking increasingly large doses? Seems like once you hit the normal levels in your blood taking more is a waste of money?

I haven't had blood work done recently tho I do notice the difference if I'm away or forget and don't take the supplements regularly.

Cost isn't really an issue, I pay 15 dollars on Amazon for 360 5000 IU softgels.

Should note that I work in a windowless office room and almost definitely get less sunlight then the average person.

Apparently we synthesize ~10,000 IU just from being outdoors on a sunny day for a couple hours.
