I have been buying this vit c by Sisu for many years, and have always been satisfied with results. My family takes vit c during winter to boost our immunity. Highly recommend.
I have been using this for years and product is excellent!!
I've been taking this vitamin C supplement for some time now and have only recently tried the "supreme" version. Am happy with it
I feel much more protected using this supplement, especially during the flu season. I'm very satisfied with this product, since it also contains no citrus.
Great product and great value!
We use this product often...great!
My wife has been using SISU Ester-C Supreme for years and she swears by this brand of vitamin C. It is non acidic and the quality of this product is excellent. Will continue to purchase!
Vitamin C has been a staple in my vitamin regime for many years now. I take it year round to increase iron absorption, improve my thyroid function (I'm hypothyroid), and to increase immunity and energy..just to name a few. After discovering I had a sensitivity to citrus, I was so happy to find SISs Ester-C Supreme which is citrus-free!
