I came down with the flu last week and a friend mentioned taking Vitamin D three days in a row and also putting hydrogen peroxide in the ear. I went a few days later when I was feeling better to Whole Foods and the only kind I could find was Vitamin D3. Most of the brands were made from liver sources, which I thought might be high in mercury, so I settled for vitamin D3 from Lanolin - also cholecalciferol. Anyway, I have been taking 1-2 softgels (2500 IU) a day with food. Immediately the raspy cough that I can't quite kick disappears. The amazing thing is that my psoriasis around my nose disappeared after taking the first dose. But both the cough and the psoriasis came back when I stopped a few days later. My thought is that I am not taking enough D3.
Question to those who know about Vitamin D3 -- How much is a good daily dosage? If it takes 30 minutes to get 10,000 IU from sitting out in the sun, I imagine you can take at least that amount. I am seeing that some people take up to 50,000 IU a day, but that seems a little high to me!
