It’s winter, how’s your Vitamin D?

Vitamin D3: Vitamin D3 is a pro hormone and is vital to immunity and to other physiologic functions. Vitamin D3 is an important neuro-steroid hormone responsible for many elements in brain development and behavior as well. Vitamin D3 increases brain levels of glutathione, a powerful natural antioxidant that is the body’s most important tool for detoxifying and excreting heavy metals and one that is rapidly consumed during oxidant stress from toxins and other sources. Vitamin D3 is made from LDL cholesterol in the steroid chain. Most vitamin D3 in the American food chain is added and is D2 not D3. This is especially true in dairy products. The active form of vitamin D is D3 and is made in our skin by sunlight. The best dietary source is from fatty fish or other animal products. Few people have good dietary sources of vitamin D3. Vitamin D3 can also be made from sun exposure but the dermatologists have done a masterful job of convincing many they will succumb from skin cancer if this is their major source. So most americans do not get vitamin D3 this way either. This is why we have an epidemic in patients with low vitamin D levels. Most americans fail to even get the low RDA of 400 IU from all sources.  For this vitamin I suggest a basal dose of 5000IU for most patients. For those who are suboptimal I will push this big time. And I am no fan of 50K of Vitamin D2 a week…….its suboptimal dosing with a suboptimal form of Vitamin D for humans.

  1. Great post! I’m still figuring out what the optimal dose for me is, and trying to get sun every day in addition to supplements. I have noticed I don’t burn as much as I used to–just get tan without the burn! I posted on weighing the supplements/sunlight on my blog… http://www.grassfedgeek.com/2013/05/vitamin-d-optimization-sunlight-or.html
