Product Reviews

  • When I turned 50 (18 years ago) and had a list of complaints and was put onto OPCs. The difference was so noticeable that people commented.


    I had sore joints, red eyes, skin that when pinched would stay that way, restless legs, poor heath (when I never used to get sick) and other things I cannot remember now as it was 18 years ago. I now take them 2-3 times a year as maintenance but when I first started taking them I took them for 9 months continually and every symptom disappeared. For me they are the best antioxidant on the market and they are NZ made.
    When I first went to the health shop with a list of my complaints he asked me if I had tried antioxidants and I showed him all the different ones I had tried but not the OPCs as they were more expensive. Well I could have saved myself all that money and put it towards OPCs. I have put them onto other people but not all antioxidants work the same on others but they certainly work for me and today I am totally pain free.



  • very good cant go without it!!


    This definitely helps me ease menstrual cramps and headaches with change of diet a little bit. I have also noticed that I feel bit warmer after taking it..



  • OPC was recommended to me years ago...


    OPC was recommended to me years ago and I can feel the difference if I don't replace it after a relatively short time. It has helped my chest as an asthmatic. Won't stop using it :)
