Think I'll get out on the deck without a shirt the next nice day, shorts if it's warm enough, in late morning my back deck get lots of sun and is much warmer than the outside because its sheltered. Time for some sun and natural vitamin D at the first opportunity.

D is for Debacle - The Crucial Story of Vitamin D and Human Health
From 2014
Leveraging the knowledge of the foremost experts in the field, I can now release what I believe is a comprehensive explanation of the Vitamin D story. It's benefits are difficult to disentangle from those of healthy Sun Exposure though - the beneficial effects of D status may be hugely due to the sun exposure that got your D up! I use sun and UV sources to achieve my D levels as a result, not supplementation. Other key elements like K2, A, Mg, Ca etc are inextricably linked also, but here we focus mainly on D. Reverse Causality applies also - people who have inflammatory issues and are obese may drive down their D status, but data on this is sparse - but keep it in mind. Also important is that DAILY supplementation rather than big bolus dosing is used - the half-life of D3 is only a couple of days.
This Seminar is of interest to Mothers & their Children particularly (e.g. see 15:00:00 to 21:00:00 segment), to avoid probability of serious chronic diseases, in childhood and beyond. The main message is that blood levels of D should be targeted towards healthy evolutionary levels, ideally through access to UVB / healthy sun exposure (NO burning). So to stress again: there is a lot of associational "correlation but possibly not causation" data in this, and there is every possibility that Sun exposure delivers more benefits than D3 supplements (by the production of many other photoproducts in the skin), and also the modern carb-inflamed/diseased population may be causal in driving down 25(OH)D status (e.g. the obese people with low D - is it their fat sequestering away the D, or is their inflammation driving down their status?) Anyway, thanks for watching! Ivor Cummins BE(Chem), CEng MIEI December 2014
