Hey everybody, it's been a little while since I did a video for you. So today it's been on my heart, what would have the most impact for you? And a lot of people are asking me, "What should I do about supplements? What's a good supplement?" Recently I was asked, "I need some fat loss supplements, because I want to burn fat faster," and so, not that that's what I want to talk about today. I really want to talk about supplements, the purpose behind nutrition, and why we need to be healthy. Specifically, one of the most powerful, most impactful substances that the human body needs is vitamin D.
Vitamin D is what prevents osteoporosis, but also, believe it or not, it prevents heart disease, high blood pressure, and cancer. Many types of cancer are because of low vitamin D, including skin cancer. But also it can cause dementia and Alzheimer's. So if you think about all those things that vitamin D can prevent, why aren't more people supplementing with vitamin D? Well first off, a lot of people are, but they're not supplementing with enough vitamin D or the right type of vitamin D.
I also want to tell you what vitamin D is. Vitamin D is actually a type of cholesterol, believe it or not. When your skin gets exposed to sunlight, it converts cholesterol into vitamin D. So a lot of people are on cholesterol-lowering medication, and their cholesterol's really low. That leads to vitamin D deficiency. We also probably don't have the right parameters for how much vitamin D we really need. I've read in different articles that if you're spending a lot of time in the sun, you can produce up to 8,000 international units, IUs, of vitamin D per day. When we supplement, the recommended daily allowance is only 400. So if we don't need 8,000 IU, why does the body produce that much? And if we DO need 8,000 IU, then why are we only supplementing with 400? Now, vitamin D in high doses is very, very toxic, so don't start taking 8,000 IUs of vitamin D on your own, it should be under supervision of a doctor.
Mainly what I wanted to tell you today is that cholesterol becomes vitamin D in the body and also becomes many other things. We'll talk about that on another video, but vitamin D needs you to have cholesterol in your body, and it's required for all these systems in your body- your heart, your bones, your immune system, your skin, everything. A lot of people say you get cancer from the sun, but if you look at the data and the research, countries in areas of the world where you don't get a lot of sun have higher instances and incidences of melanoma, skin cancer, than they do around the equator, where people are in the sun a lot more. So that can't possibly be true. So make sure, if you're going to use sun screen, use an organic, safe sun screen, because that can be more harmful than the sun. And unless you're burning your skin, unless you're staying outside long enough that your skin burns, you're not really doing damage to your skin, so keep that in mind as well.
I appreciate your listening. We'll talk soon.
