But there's one other supplement that is as important as minerals that's intimately tied with minerals in a way that people don't understand. And that is vitamin Dake. Have you heard of that? No. Max, you have. D-A-K-E. This is all of the fat-soluble vitamins all together. So, we all know about vitamin D. I've been hitting that one, geez, since I started my first blog post. Vitamin D3 is so important. But if you're not taking vitamin K2 with it, you can actually have vitamin D drive calcium into scar tissue, into your arteries. So, it's critically important you get vitamin K2 and a little bit of K1, probably, with your vitamin D3. But if you do that and you don't have enough vitamin A, vitamin A is part of what drives minerals into your cells, including iodine. And plant-based vitamin A doesn't work. Beta carotene is not vitamin A. No matter how many times you call it plant-based vitamin A, it doesn't magically transform into retinol, which is the substance you need. So, when you take vitamin Dake, which is something I'm making for Upgrade Labs, but you don't have to take it. You can buy a vitamin E here and a vitamin K2. You can do all these things. And when you do that, magically, the minerals you take will go into your cells and stay there where they belong. But if you take minerals and you don't have your fat solubles, the minerals don't work.
