Rated 5 out of 5 by from Ester-C Tabs Although this is a great product I really prefer the same product in the capsule form. I have recently changed to the capsule form and it seems to work better for me.

Rated 3 out of 5 by from Too Big I love Ester C and in my desire to be more efficient and get a better bang for my buck I decided to try the 1000mg vege tablets, but they're really big and can be hard to swallow. The 1000mg capsules are also a big big, but I don't have any trouble swallowing them.

Rated 4 out of 5 by from Huge Tablets I actually wanted capsules and ordered tablets in error. And boy was it an error. The tablets are so huge I was afraid to take 'em so I broke them up before swallowing. Effective, yes, but I'll be careful the next time and order capsules. I'd rather have a bigger bottle and smaller tablets.

Rated 5 out of 5 by from Excellent Vit C This is easy note stomach and it supposed to stay in the body longer then regular vit c.
Date published: 2013-04-30
Rated 4 out of 5 by from pills just too big The size of these pills create a choking hazard.Breaking or splitting them leaves jagged edges, which will irritate your to find a better way to get my vit C.

Rated 4 out of 5 by from Long acting C I use this product for it's longer affect in the body. I have to take a prescription iron and vitamin c aids in the absorption of iron. Ester C is said to last 4 times longer than regular Vitamin C in the body and it doesn't upset your stomach because the calcium in it acts as a buffer in your stomach. I've been using it on and off for many years and am happy with the result. Would like to see a 1000mg cap. :)

Rated 5 out of 5 by from Best in Class! Of all the Vitamin C products out there, this is my top choice. Never any stomach upset with this, and the inclusion of the Citrus bioflavinoid complex enhances the value of the product immensely.

Rated 5 out of 5 by from I've been taking this product for some time. I always bought the 500mg bottle. But when my doctor told me to up my dosage, I got this 1000mg bottle, just to find out that the tablets were so big. I have difficulty swallowing them. you may want to get the 500mg ones and double the dose that way. If you fear choking, stay away from that size.

Rated 2 out of 5 by from Ester-C Produst Name Because of the product name; e.g.; Ester-C vitamins called "Veg Tab" I ordered 2 180 unit bottles thinking it was Capsules. Unfortunately I opened one of the bottles and found I could not swallow these horse size Pills, -not capsules. The 2nd bottle is unopened, and I am stuck with over a years supply of vitamin C tablets I can not swallow.

Rated 2 out of 5 by from Ester C I ordered 4 bottles of Ester C and the capsules were not filled up. About a quarter of an inch of ingredient was missing so I don't know if they will be effective. I have purchased Ester C for years and this is the first time its happened. Very disappointed with this product and Swanson was not helpful either, they just told me to send it back, well I didn't want to go through the hassle.

Rated 2 out of 5 by from Giant tablets I think the product is good but the tablets are just so huge they're hard for both my mom and I to swallow. Had to return them. Will try the 500mg - hopefully they'll be easier to get down!

Rated 5 out of 5 by from The Ester-C does not irritate the stomach, & yet is very effective product. Convenient flip-top to the container is nice. Easy to swallow capsules.
Date published: 2012-03-29
Rated 5 out of 5 by from SAFE Product I only buy supplements that are gmo free and this product is one of the least expensive that fits that criteria. Also, it's easy on the stomach. Vitamin C is one of the supplements our family takes every day and it makes a positive difference in our immune systems.
Date published: 2012-03-27
Rated 5 out of 5 by from Ester-C I think this is an outstanding product. Was looking for a Vitamin C in capsule form with calcium ascorbate as the Vitamin C instead of ascorbic acid, and also wanted bioflavonoids in it. This one fills the bill! Price also can't be beat. They also offer you a choice of regular gelatin capsules, or the same product in veggie capsules.

Rated 5 out of 5 by from If you want a Vitamin C supplement this is it! I have taken a few different Vitamin C supplements over there years and settled on this one! It is gentle and has the dosage. I have taken this a long time and will continue to do so for years to come! Vitamin C may have a lot of hype but I believe long term is does a LOT of good.
Date published: 2011-11-11
Rated 5 out of 5 by from Great Product I spent hours online looking for a vitamin C product that is gmo free and, of only a few available, this one is the best value for what you get.
