Immune System Booster

Posted by Reviewer2001922 on Sep 30, 2008

Fights and prevent colds. I use mega doses, recommended by my doctor & haven't had a cold in years. If cold systems begin, take more Vitamin C & in a few days, cold symptoms are gone. Can't recommend dosage as varies per person.

Doesn't cause diarrhea like regular c

Posted by MGG-ThreeTwoFour on Jul 22, 2015

I wanted a vitamin C with bioflavonoids and this one fit the bill. Have been taking it for a year now and it works very well. Part of my detox. Ester C one of the most potent vitamins that keeps you healthy. Doesn't leave your body until its entirely consumed. Doesn't cause diarrhea. this is the best I've found yet.. ** For new customers of iHerb, please also visit my page for more product reviews **

Ester-C is the only Vitamin C to take

Posted by Reviewer1337399 on Aug 26, 2008

Just love Ester-C. Regular vitamin C can mess with your pH balance and stomach, but not Ester-C. Easy to take. Vegetarian friendly. Good product.

This is a great product! The Ester-C formulation doesn't give me the acid reflux problems that regular Vitamin C does.

Regular C kills my stomach; these are fantastic. Don't notice any acid feeling.

A good vitamin C

Posted by 5238752515546516415 on Jul 24, 2012

The best vitamin C I've ever used. No more acid stomach! The Exter-C is much more absorbable than others!It also can enhance the ability of the body against a flu pandemic
