Easy on the belly
I can take these on an empty stomach with zero issues. The pills are too big, so I need a lot of water to get them down, but it’s worth it. This is the only vitamin C I’ve found that doesn’t cause upset stomach – and I’ve got a sensitive belly.

Ester C BUT ~ Why is this product so expensive now??
This product looks like it’s made in the USA, so it’s perfect ~ EXCEPT needing it for medical reasons, like most of us is horrible to have to pay double the price!! ~ I get it, we are all fed up with high prices and on a fixed income it’s worse! I think Amazon could be a bit kinder on Supplements. ~ ~ Okay, this is the best Vit C, easy to swallow, doesn’t bother stomach. I’ve been buying this on Amazon for years, BUT, ”the Price” was always $6.97” Not sure I want to shop here for this double price, so very disappointing! ~ The last time I paid $6.97 was Jan/2024 and I stocked up because this happened once before, double cost to us. So, check in folks, hope it comes down to a decent price, stock up!!

Good Value for 500 mg C
I purchased these when I saw them on sale. I’ve been wanting to try this brand because I’ve read alot of good reviews about Ester-C. There are 2 quantities listed- I purchased the 1 bottle of 90 count. It arrived boxed and safety sealed with expiration of 1+ year out which is great. These are large pills, as vitamin C often are. I haven’t had any trouble swallowing them and they did not upset my stomach, even when taking in the morning on an empty stomach. It’s great they are Non-GMO. One thing to note is that these are only 500 mg per dose. So, if you take a higher daily dose, it may just be easier to buy a higher strength 1000 mg pill rather than having to take 2 of these.One recommendation is to compare the cost per vitamin. There is an option for 2 bottles of 60 each (120 total) or a 90 count. I paid just under $7 on sale for the 90 count, and looking at the listing today, they are priced on sale even lower. Currently, it is cheaper per pill to buy the 90 count with each costing about $0.07 per pill, versus the 2 pack being $0.08 a pill. Not a huge saving, but everything adds up. Prices fluctuate, but if this is something you use daily be sure to compare cost per pill because the larger quantities aren’t always the cheapest. 😉 I hope you found this review helpful. Happy Shopping!
