First of all: it's probably not a good idea to be dispensing (or receiving) medical advice on HN.
That being said-- Vitamin D is fat soluble, and too much vitamin D is definitely harmful. Take a look here:http://en.wikipedia.org/wiki/Hypervitaminosis_D http://en.wikipedia.org/wiki/Hypervitaminosis_D
Vitamin C, on the other hand, is water soluble, and much harder to overdose on.
- burgerbrain 16y agoDid anyone else find themselves clicking on that link very cautiously? Wikipedia should really institute some sort of official warning system for articles with shocking medical images. (this article does not have images)
- pjscott 16y agoThe biggest Vitamin D supplements I've seen have 1000 IU per tablet, and the bottle suggests one tablet per day. According to the article you linked, 10,000 IU/day is safe (we can get that much from sunshine in a day), and long-term overdose has been observed at 77,000 IU/day. You'd have to go pretty hog-wild with the Vitamin D supplements to overdose.
- gregwebs 16y agoThat article is just about Hypervitaminosis D, other harmful effects are possible (depending on the individual) when supplementing at high levels like 10,000 IU/day.
- nkurz 16y ago2000 and 5000 IU are quite common and can be bought at any US pharmacy and many grocery stores. It looks like 10000 to 50000 IU pills are easily available online: http://www.amazon.com/s/?url=index%3Dblended&keywords=vitamin+d3+10000 http://www.amazon.com/s/?url=index%3Dblended&keywords=vi... For what it's worth, I supplement using the 5000 IU pills taken at about 7/week (irregularly, making up doses as necessary). I recently had my blood tested for D3 levels, and found it was close to but not exceeding the standard recommended level.
