My doc said my D was very very low.....he told me to take fish oil and I said NO THANKS.....so the hunt was on. I did try a number of brands but the blood test day NOT ENOUGH YET......so I kept searching for the RIGHT D-3 Then I came across these and gave them a try.....WOW my next blood my doc said it had come up 10 points and I had not been taking them but a couple of weeks. The other failures I had taken for months. These are easy to take....they are small and do not sit in your stomach like FISHY Omega3's do and also these do not cause indigestion. I am so thankful to find them and so far my Blood count on my D is GOING UP UP and up.....another month and I will be back to THE magic number and it will make my doc smile....and my BONES also. Just to make sure my bones stay healthy I will keep taking the D-3. I mean it is EASY and so very good for you! These were a winning find..... and MY bones will thank you as well............ :-)
