STAY HEALTHY THIS WINTER
I’ve been very happy with Ester-C 500 mg. I like that it provides 24-hour vitamin C support and is gentle on my stomach compared to other vitamin C supplements I’ve tried. It’s easy to take, well made, and gives me confidence that I’m supporting my immune health consistently. It's winter stock up!

GOOD PRODUCT.!!
I have been using this product for numerous numerous years since it was placed on the shelf for supplement products. The tablet itself is easy for me to swallow and the taste is good. I like the idea that it helps with immune support (which we need help with). I even give my husband a tablet daily. I will continue to take this product.

A staple in your cold care remedies
I swear by this regime whenever I am getting or am sick: - this product - immunity juice shot - echinacea tea - electrolytes I find this product way better value than purchasing emergenc or other similar products. I swear this shortens my cold and lessens the intensity.

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!!
