You’ve come to know ANX-P3 as a great pre-workout product that gives you a great pump. But it’s also got some other great properties, including a healthy dose of OPCs (oligomeric proanthocyanidin complexes) that specifically help with vascular function and the prevention of swelling and other blood-flow abnormalities.

Since ANX-P3’s primary function is to promote improved blood flow for that crazy workout pump, it stands to reason that OPCs would be included in its proprietary blend. Sure enough, a closer look at ANX-P3 shows them in the formula, in the form of Grape Seed Extract, PowerGrape Whole Grape Extract and Pine Bark Extract Concentrate. The early uses of OPCs for treatment actually were derived from the extract of French maritime pine.

OPCs are, according to the NYU Langone Medical Center, a family of closely-related compounds that has been used for years to treat myriad symptoms, including chronic venous insufficiency (similar to varicose veins), erectile dysfunction (when paired with arginine) and PMS swelling, on top of improving cholesterol and serving as a fat- and water-soluble antioxidant. From the Center’s website:

OPCs are strong antioxidants. Vitamin E defends against fat-soluble oxidants, and vitamin C neutralizes water-soluble ones, but OPCs are active against both types. … Regular use of OPCs has been proposed as a measure to prevent cancer, diabetic neuropathy and diabetic retinopathy and heart disease.

A double-blind, placebo-controlled study … reported that use of OPCs from pine bark produced benefits in all symptoms of menopause.

On top of the inclusion of OPCs, you’ll also note the Beet Root Extract Concentrate in ANX-P3’s main blend — it is known to be key for lowering blood pressure, another significant benefit when it comes to vascular health.
