Standard Process OPC Synergy - Supports Antioxidant Activity - Aids Cellular Function & Brain Health - Aids a Healthy Heart - Supplement for Eye Health - 150 Tablets

It seems to be effective.

I am absolutely satisfied with quality of OPC Synergy. It works great. I feel more focused and my memory is improved since I started to take this supplement for the last 2-3 weeks. It really helps me to study for a very difficult exam.The delivery of OPC Synergy was very prompt.

The product was recommended to me by my naturopath, and I've yet to be disappointed by any of her recommendations. She also recommends a lot of the Standard Process brand, so I trust it. OPC Synergy is a whole food with green tea, and the good parts of wine in it(I'd still rather drink the wine, but I can only down so much green tea), so I'm certain that's in doing me good. I believe in prevention, and so far I have yet to get any kind of illness, and haven't for years. The thing about using food for your health is that you can't see immediate results like you would with a pharmaceutical. The trouble is, pharmaceuticals also come with a boat-load of side affects, while nutritional supplements don't, unless you count having more energy than your friends of the same age, a side affect. This is one supplement that's going to be ongoing in my life.

Good for those with ADD or ADHD. My son takes this with mini-Tran, tuna omega chewable and inositol.You can tell the difference when he doesn’t take them or if you try to substitute with another brand.

haven't used it long enough to know

Standard process makes the best products, hands down. This one was recommended by my doctor for slight ADD problems. Helped me tremendously.

Good product and give me a boost when I need it.

Ok
