Vit.d3 supplements

Im in a quandry. My gp has given me 1000IU to take daily plus calcium & vit.d3 supplements for osteoporosis. He took bloods and found my levels of vit.d3 to be low. Ive joined the osteo site and some have been told to not take the extra load when its sunshining but take the supplements. Those who take extra can you please advise whether to continue when its sunshining or leave alone until the bad days? bren x

Thank you Paul, Ive had so much conflicting advice I dint know whether to take all Ive been given. Now youve put my mind at rest Ill start tomorrow. Cheers, bren
