This is my top choice for vitamin C. Super fast order processing in these crazy times.


Get serious. How can one determine the efficacy of a supplement in such a short while.

Best Ester C is SISU

I am so pleased to have tried Sisu Supreme Ester C some years ago and will NOT go to any other even though the price is somewhat higher than the other brands. Supreme is with berry bioflavonoids and quercetin which are all much better for me than citrus bioflavonoids. If anyone out there has some allergies or at least sensitivities, this is the one to try. I also like the amount in one capsule 500mg. instead of 1000. That means flexibility for me as to how much I need to take in one day depending on the state of health that day. I need more if I have been out in the wind or pollen, or just feel tired, for instance. I have chronic sinusitis as well as several sensitivities so this particular one is best; also the ester C means it is coated with calcium and therefore does not bother my stomach. During this Covid 19 crisis, one day when I accessed the Vitasave site, I did NOT see my favorite Vit C was out of stock. I was so shocked that I even called Sisu to find out when stock would come in. THAT is how much I depend on this product.
