This is not a question but some helpful information.
I normally get my Vitamin D3 from Holland and Barrett when its on offer but have just found a real bargain on Amazon. They are called Vita Premium Vitamin D3 4,000 IU High Strength so only need to take one a day. They cost me £12!!!! Even in the penny sale Holland and Barrett charge £18 for 250 and get another for a penny, so say 500 tablets (2,000IU). I normally take 2,000 IU a day but 4,000 should be fine from what i've read up on. They are softgel capsules as well.
