What Works !!

I have been buying Vitamin C -- Ester-C from the Vitamin Shop for 20 years. The Vitamin Shop is always my first go to store and when I can't get to the store I order what I need. If I feel a cold coming on I'll take an Ester-C and I'll knock it out of my system.

Hands down the best C

I've been taking this product for more years than I can remember and I can testify to its effectiveness. I prefer capsules over tablets because they absorb than tablets. I also prefer Vitamin Shoppe because of their prices and service.I've been a customer for many, many years and will continue for many more years. TAKE IT EASY

Best Vitamin C in the world. Used for over 11 years.

Every pill that is 100 mg will be this size, so for anyone saying it is a horse pill hard to swallow should break it up, or get 500 mg and take the dose you need. This is the BEST vitamin C ever. It is whole food and natural, not so much corn based like another user thought. I have been taking Ester-C for over 11 years with NO issues. I would not buy any other type of vitamin C. The recommended minimum is 2000 mg a day.

Why did you choose this?

A shopperMar 4, 2015

Past research has led me to believe that Ester C is absorbed much better than other forms, and that bioflavonoids add to the benefits.
