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.
