Easy Vitamin C2000
Verified Purchase
It contains a lot of vitamin C, but I feel like it's better absorbed in a drink than in a supplement, so I'm not taking it right now. It might be good for people who aren't too tired and want to take it easily.

very good product tablet too big
Verified Purchase
Great product tablet big but easy to swallow. When I skip a day I can feel the difference. The tablet size is understandable since it is a slow release.

High potency but the body cant absorb it all so no worries about hitting the daily limit
Verified Purchase
Since the body cant absorb it all there is no worry about taking such a high dosage in fact the high dosage is perfect to get more vitamin c naturally in the body.
