Easy on the stomach, assimilates (or at least I think so), and seems to be the best one I've tried. Highly recommend.

Doctor’s Best is one of the supplement brands that I trust. I have seen numerous positive reviews on YouTube. That said, I have recently started taking this “time released” version of vitamin C because of a vein condition I have developed. This replaces a different brand that had questionable efficacy. The one interesting point I can make is about the capsules themselvs. They are not marked in any way, so you have a be careful not to mix them up and other unmarked supplements. I see this as a good thing as no food coloring has been added to this product .

I ordered it, it was shipped, I got it.

This vitamin C is of super high quality, as are all Doctor's Best products. I was taking a lot of different things for my immune system, which were working; however, I would still get a cold or sinus infection at least twice a year during the winter and early spring. Since I have added this vitamin C product into my regimen (for the last 10 months or so), I have not gotten since ONCE. And that says something because my WHOLE office got sick multiple times and I was pregnant during 9 months of that time and therefore more susceptible. I now simply can't live without this amazing supplement.
