If you take supplements, make sure you take gelcaps and not dry tablets. Vitamin D is fat-soluble, so it is absorbed much better in gelcap format.

Personally, I take 6000 IU/day during winter and 4000 IU/day during summer (in Canada).

Wow, you're really taking 10x the recommended dosage [0]. You're in fact, very close to overdosing or according to some studies, already overdosing.

The studies I've seen have shown have very different numbers, and show that our bodies are very good at dealing with lots of Vitamin D but very bad at dealing with too little. From what I know, there is no known negative side effects under about 14,000 UI a day, and based on blood tests, Dr. William Davis, a cardiologist, has been recommending amounts in the range of what I take (even a bit higher). The official recommendations have been too low for a long time.

It's quite possible that too much vitamin D could be bad for you, so going overboard might not be a great idea either.

Pretty much all formats are preferable over tablets, yeah. Drops, kids' “candy” versions &c.

Indeed, but I believe - based on the research that I did - that these amounts are quite safe, and with a good margin of safety too.

I've been taking mine as a dry pill. In lay terms, can someone explain why this is worse than gelcaps?

8000 iu daily here following blood levels with my MD. Dosing should probably be weight based.
