In my opinion, there are higher quality products out there than this. I'm not really a fan of this brand.

Ester-C 1000s w/ Citrus Bioflavonoids

Other than the size (I need my esophagus stretched) which I find a challenge to swallow, I love that this supplement is a more complete Vit C than you usually find. Would buy it again.

I am a teacher and every year the kids get me sick. This year, I have been taking Thrive multivitamins and this vitamin C supplement. Knock on wood, I have not been sick yet this school year.

good bargain

This is the vitamin C that I take every day. Capsules are on the large side but they go down easily. Not hard on the tummy. I believe they are partly why I have not had a cold in the past years.

C-up fellow Winterites!

I jam in this Esther C every winter and have gotten through each year with just a bit o' sniffles here & there ...just to allow myself to pass as "just another ol' dude" amongst the amidst the passing throng! I feel good at 71 and often. just being "Vertical & ventilating" at this time of life is quite good enough! (when I add a dose of whimsy and a heap of Joyful Gratitude)! Feels good to have this Vita Insurance in my veins!
