Winter Sunshine and Vitamin D Synthesis

November 11, 2019 3 By Stanley Isaacs


hey it’s dr. Jory so what’s the deal with vitamin D synthesis in the wintertime well if you live in a northern climate anywhere in Canada a lot of the US Europe Asia Siberia a lot of these places do not have any vitamin D synthesis from the months of november to march it doesn’t matter that it’s a beautiful sunny day in February I’m out here on Lake Huron but I can’t get any vitamin D synthesis from all that sunlight the reason is the Sun is too much on an ecliptic it’s not straight overhead even though it’s noontime it’s on quite an angle which reflects the ultraviolet B radiation off the atmosphere and then we can’t get that vitamin D that is why it’s crucial to supplement with vitamin D through the winter months there is no better supplement than the Sun so even though the Sun is blazing out here I could stand here naked and get no vitamin D synthesis whatsoever as usual subscribe to my channel leave a comment hit the like button and until next time get your health on!
