My friend Patti Kimler has great info on vitamins D3 and K2. She writes, “Let’s talk about Vitamin D3! First of all, it’s not a vitamin, it’s a hormone. Second, you probably don’t have enough of it floating around in your body. And third, it’s being proven to the be the greatest immuno-regulator that your body has to work with. If you put on a tank top and shorts and go outside for 20 minutes in the sun (without sunscreen), a fair-skinned person’s body will manufacture 10,000 IU’s of Vitamin D3. When your blood is tested, a healthy person should register around 100 units of Vitamin D3, but that number is likely to change. (A person like me with MS should have a D3 count between 150 and 225). The Vitamin D Council (I bet you didn’t know there was one), has been trying to get the FDA to raise the RDA of Vitamin D3 from 600 IU’s to at least 1000, but it’s been slow going. Immuno-regulator? What the heck is that? When you have an auto-immune disorder/disease, like MS, your immune system (usually the T-cells that are manufactured in your lymph glands) attacks some part of your body that it should recognize as part of your body but doesn’t. D3 is being shown to be the light that switches on and shows your body what it’s doing, so it stops! All over the world, D3 is being used to treat everything from autism, rheumatoid arthritis, HIV, ALS and many others.
