No side effects but no noticed benefits

Posted by PurplePegasus on Apr 03, 2016

Just I think it's because I was diagnosed as low on vitamin D. My doctor wanted to put me on a 50000 IU pill once a week and that would have been too much for my system. So I take this as maintenance, 1 a day. I guess it's good enough.

Seem to work fine

Posted by Herbal-Andy on Feb 21, 2012

My wee turns conspicuously orange so they're surely going through my system. I am left wondering if vitamin D can be readily absorbed this way- bulldozing huge quantities down your throat instead of getting out in the sunlight.

Good product but...

Posted by Reviewer2827458 on Jul 05, 2011

I found this vitamin affected my digestive system . There were rumblings and gas. A bit constipating for me. I cut back to every other day and it worked better.

I take these every morning and when I don't I recognize the difference.

I take the Vita-D for a mood booster during the no sunshine winter months. I think they help for a happier disposition.

NOW Vitamin D-3

Posted by Reviewer2927672 on Jun 05, 2010

I like the NOW D3. I think I will move up to a higher potency. I thought I had purchased 2000IU.

NOW Foods, Vit. D-3

Posted by Reviewer2996308 on Apr 28, 2010

My blood test for Vit. D was low; therefore, I am now on this vitamin for a short period to determine the affect of same. Hopefully, my level will increase. Price is excellent.

Easy to swallow

Posted by Reviewer2012393 on Apr 02, 2010

My doctor told me I am low on vitamin D. I feel calmer and more energetic after I started with this product. Can't wait to see my blood result next time. I will then know for sure if this is really working.
