Sun, Sand, Sea… And Vitamin D!
This year, some of us at ISS have been fortunate enough to be working with clients in Europe, “forcing” us to soak up the rays of European summer!
Although technically a hormone and not a vitamin, vitamin D is produced by the body in response to sunlight exposure. Dr Stasha Gominak, a neurologist at the East Texas Medical Center has found that most of her patients had improvement in sleep, but only when vitamin D3 blood levels were between 60-80 ng/ml (which is 2-3 times higher than most official recommended levels).
In order for the majority of people to reach stable levels of vitamin D in this range, daily use of a supplement is required. To absorb vitamin D3 research has shown vitamin K2 is also needed, and are often found together in supplements.
