Thank you very much for that link, that was quite interesting. I take 1000 IU daily - but will try the 2000 since I have one very bad knee.
Best to stock up while these are still at a reasonable price. Once the vitamin companies learn about this the price will probably go up.
From that site.
“2,000 IU is now the revised standard. I take 5,000 IU daily. I never get colds and since I increased my intake recently, I no longer have debilitating pain in my knees.”
