Take Vitamin D

Vitamin E = bad
Vitamin C = no effect
Echinacea = no effect
What good is any supplement? A slew of recent good data is supporting taking vitamin D. Recent studies have shown vitamin D supplementation might reduce breast cancer, colon cancer, and prostate cancer by as much as 50%.
What dose to take. It seems that the USRDA of 400 IU of vitamin D per day is too low. It is just enough vitamin D to prevents rickets. It is early to say but it appears that we should be getting 1000 IU per day to get sufficient anticancer effect.
Is this just another premarin or vitamin E that doctors are pushing today and will be pulling tomorrow? I cannot say for 100% certainty, but I believe that vitamin D will likely emerge as one of the few supplements you can take that is likely to make you live longer.
Now how to get all that vitamin D? It's actually hard to find just vitamin D supplements on the shelf. I comes in Oscal & similar calcium tablets. But you'd have to take 5 such tablets typically to get 1000 IU. I think we will be seeing more ready availability in the near future.
