pure, simple Vitamin D

Posted by iHerb Customer on Oct 09, 2011 | Verified Purchase

Most everyone needs more Vitamin D and I did. I feel better when I use it and sleep better too.

Thanks for your feedback!

Look to Superior Source

Posted by iHerb Customer on Dec 03, 2017 | Verified Purchase

It is most often hard to tell if supplements are helping. Working with my doctor I fine tuned my levels of "D". I was taking 5000 units in gel cap form and my vitamin "D" levels were only at 43. My doctor wanted my levels at 100. So I switched to Superior Source 10,000 units. The next time my levels tested at 140! So I dropped back down to 5000 units of Superior Source and I then checked at 89. So the Superior Source were absorbing far better. I since added another 400 Superior Source tab. I expect that next time I will test very near 100. I also use Superior Source B Complex, and my B levels checked good too. I will continue to look to Superior Source.

Thanks for your feedback!

Easy to use

Easy to dissolve and use. Haven't noticed a big change from taking them, but it's an easy way to boost Vit D.
