Doesn't cause diarrhea like regular c

Posted by MGG-ThreeTwoFour on Jul 22, 2015 | Verified Purchase

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 **

Thanks for your feedback!

Immune System Booster

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.

Thanks for your feedback!

Ester-C is the only Vitamin C to take

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.

Thanks for your feedback!

Great product!

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

Thanks for your feedback!

A good vitamin C

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

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

Excellent when taken at the time of an infection. Definitely cuts it down to a minimum
