I buy Resveratrol from PureClinica. I noticed an improvement in my breathing (I had shortness of breath after Covid) after taking it. I tried cutting down to one tablet every second day and the breathing problems returned. That shows that the tablets are helping.
Great friendly service..plenty of info on all vitamins...will definitely be using again and again..
I have been purchasing all different products of this company for years and found all to be excellent
Excellent product can fault the quality I will be buying more
