OPC nutritional supplements have been around for over 50 years, yet they are only now coming into the antioxidant nutritional forefront.

OPCs are a molecular compound extracted from pine bark and grape seeds. Jacques Masquelier from France received his first patent in 1951 and got his final OPC patent in 1985.

Why should you care about the history of OPCs? Because whenever a beneficial thing is discovered, there are always novel products developed that claim to be the same thing, but really aren't. More about that later.

As expected with any investigation on nutritional supplements, there are widely conflicting reports on what OPCs can do. Here is a listing of some of the claims I read:

" Averts heart attacks and strokes

" Strengthens capillary walls

" Reduces varicose veins

" Relieves leg cramps & pains

" Preserves smokers from oxidative stress (lowered risk of heart attacks)

" Reduces swelling and edema

" Improves collagen and helps with the following ailments

" Lupus

" Liver Cirrhosis

" Hypertension

" Cancer prevention

" Asthma

" Allergies

" Diabetes

" Periodontal disease

" Impotence

" Hemorrhoids

" Impaired vision & macular degeneration

" ADHD

" PMS symptoms

Seriously, can it REALLY do all that? How come everyone isn't taking this miracle supplement? Here's what the sources DO agree on:

OPCs are powerful antioxidants.

There is plenty of debate on the health remedies of antioxidants. I won't go into that here. If you believe in antioxidants to help combat the damage of free radicals, then OPCs should be on your shopping listing of nutritional supplements. This is one supplement you'll have to pop the pill for. I doubt you can eat enough pine bark and grape seeds to get the full remedy of OPCs.

Varicose Veins

They seem to furnish relief from problems associated with varicose veins. This was one study that seemed pretty undeniable.

Swelling from surgery or injury

OPCs seemed to reduce the swelling from surgery in breast cancer patients, facial surgery patients and sports injuries. You can see the possibilities here.

Gingivitis and plaque development

They used an OPC gum for this study, but it seemed to work pretty well on the test subjects.

Blood clots after long plane rides

They produced it significantly reduced the risk of blood clots on plane rides around 8 hours long.

What about all the other claims? Although testing has been done on endless of the claims, sometimes the results were in animal studies or evidence SUGGESTS that a remedy may be there but there is no DIRECT evidence. So does that mean it doesn't work on all those other claims? Not at all. Medical testing is a slow and arduous task. As with all supplementation, proceed with caution and follow directions for use.

Are they safe? Apparently, yes. They are considered non-toxic. Side effects are pretty rare and can include digestive distress or an allergic reaction. One thing to note: if you take a blood-thinning drug, you should consult your doctor first. High doses of OPCs may have some anticoagulant attributes.

Are all OPCs the same? Apparently not, although that doesn't mean you won't get some remedy from the various brands of OPCs. I would suggest you look for OPCs endorsed by or with Masquelier's name on them. It is a patented product, so you should be using the original patented formula.
