- immune system
I love OPC. I was an original user and stopped for many years. Now I am back using it plus calcium. Both are wonderful
I have been taking all 3 since October 2018, love the products. I also like the bottle they come in, has a wide mouth opening, easy to take with cup and measuring spoon.
I have been using these products for years and I am very satisfied.
It has given me the best results of all the other supplements I have tried, which was very extensive. Results started 3-4 days after taking. Less joint pain & more energy. Very satisfied & placing my 3rd order.
After using these products for over ten years, I buy a six-month supply to keep my immune system at its best, especially now with the Covid-19 everywhere. CALX in this form is much easier absorbed than a pill.
