“I started taking Vitamin D3 supplements,”
Two years ago, doc checked my Vit. D3 and I was at the bottom. He put me on 2000 units Vit. D3 a day and I have been out of it for weeks, kept forgetting it. That is one thing I remembered to get at Walgreens. It happened to be on sale, get one bottle at regular price and another at half price and I did that so I now have a total of 600 gelcaps. Won’t have to think about that for a long time.
Many people are deficient in Vitamin D. It does seem to be important to a person’s immune system.
I’m on a capsule of 50K IU every 3 weeks or so. It’s a prescription. I supplement with 1K pills on weeks 2 and 3.
