In the US, you can get 50000 IU on Amazon, good enough for weekly supplementation if you're low (same as prescription strength).

The amount of fraud and fakes on amazon is surreal. I wouldn't trust something from amazon to open a can of beans that was already open.

I'm certainly not going to put something from amazon in my body. God only knows what you're actually getting

When you buy from reliable brands with a wide range of supplements in their own store on Amazon, you get what that store offers on Amazon as well as elsewhere. If you don't know the brand, Amazon is a bad place to learn about them.

I get gummies at 2000000000 IU and that's not even the final form of my vitamin

Also what's an IU. Apparently it's meant to normalize impact across vitamin D species of which there are multiple. Part of me can see the reasoning but it runs contrary to how much of medicine/pharma operates, generally in such form as either mg per time interval or mg/kg per time interval. It would be like taking the whole armada of blood pressure drugs and dictating their doses in mmHg instead of milligrams. If only things were so simple!

I recall reading some research which indicated that daily dosage resulted in slightly better protections against cancer. Though better than not taking it at all.

I just got more 5000IU at Walmart which was a nice surprise. Normally I take two 2000IU tablets.
