D IS FOR SUNSHINE
Vitamin D. Are you getting enough? It’s something that most people are deficient in. It is the vitamin that requires such a great deal of whole-body participation for it to be converted into what’s known as vitamin D3, the most active form and best utilized by the body. The skin, bloodstream , liver, and kidneys all contribute to the transformation of the fully active form, D3.
It all starts with our skin, and the sun. Vitamin D is actually manufactured in our skin when it comes into contact with the u.v. light in the sun’s rays. Hence, the name “sunshine vitamin” (in case you’ve not heard the reference before). From the skin, it’s then sent to the liver for conversion, and then furthermore, to the kidneys. So, really, vitamin D is more like a hormone than a vitamin. This is because it’s produced by one part of the body (skin) and released into the blood to affect other tissues (the bones).
Wintertime, dark skies, smog and darkly pigmented skin can reduce our bodies production of this vitamin.
Vitamin D helps a number of bodily functions. It helps regulate calcium metabolism and normal calcification of the bones. Ladies, this is especially important for us, as we get older, since the most we can do after a certain age is maintain our bone integrity. Vitamin D helps increase the absorption of calcium from the gut, decrease excretion from the kidneys (thats right, we loose it through excretion), can stimulate re-absorption of calcium and phosphorus from bone, and support minerals in teeth. On the other hand, if D is low, blood levels of calcium and phosphorous decrease, our body will pull those minerals from the bones, creating weak, demineralized bones. Blood calcium is very important in connection with the parathyroid glands. If you have further questions regarding this, it’s best to see your holistic nutritional consultant for advise.
If you are currently taking a calcium vitamin without vitamin D3, it’s probably not doing you much good unless you get a lot of sun which can also have it’s cons. So what’s the ideal bone support? Calcium and magnesium, which should be taken in a 2:1 ratio, with vitamin D together, is probably the best. Typically you can buy a cal/mag supplement and it will come in the right ratio. Often, it will include vitamin D, making it an easy supplement to add to your regime.
A-to-the-D. One final point. This is a topic on it’s own, but you can pick up an amazing Weston. A. Price book for an in depth explanation as to why. Just to put it simply though, Vitamin D is best utilized by the body with vitamin A. They are both fat-soluble vitamins that work synergistically together. They long for each other. Vitamin A food sources include, but are not limited to; high quality fish oils, good quality dairy products if tolerated (if not tolerated, perhaps fermented versions of dairy). Green and yellow fruit and veggies are the best sources of beta carotene (the water soluble co-factor). If your liver is healthy, it will have the ability to convert beta carotene into the active form of vitamin A (retinol).
Do the D. Get ample, safe exposure to sun, and supplement if necessary. Always consult your health practitioner before doing so. Love your liver, so that it can love you back, and have a bright, bright sunshiny day!
