Can't tolerate Vit. C?
This product has allowed me to take Vit C as a supplement and I believe it is the quercetin which allows me to tolerate it. I have always experienced reactions of joint pain and stiffness after taking supplementary Vit. C. Now at 70yrs my ability to fight infection and my general wellbeing has improved since using this product each morning over the course of a year. A huge relief in these times, especially.
