In the UK we are unable to get vitamin D3 from the sun most of the time, a lot of parts of the UK receive very little sun and the sun has to be
atleast a UV index of 3 rating for there to be D3, and usually when its really hot people wear sun cream which blocks the D3 which you need
for instance, the whole of the UK throughout winter is UV0 to UV1, and only very southern parts of the US has UV rating of 3, it easy to say just go
out in the sun but you need to understand what the process involves for humans to acctually get D3 from the sun, thats why taking suplaments is the
best way to make sure your allways getting a decent amount of D3.
research has found about 85% americans are D3 deficient during winter months and even during summer, a lot of people still do not receive the amount
they need due to our ever evolving lifestyles of driving, staying in doors, wearing sun cream.... etc
Take a look at this link: www.metoffice.gov.uk...
Keep in mind, for D3 to accour, the UV index has to be at least 3.
