Out of all the antioxidants found in nature, few can match stilbenoids in their capacity to neutralize free radicals. The most famous of the stilbenoids is resveratrol, which is found in red wine and in the root of Polygonum cuspidatum, but there is another member of the stilbenoid family, found in blueberries, that surpasses even resveratrol in antioxidant capacity. It's called pterostilbene, and while it has many similarities to resveratrol, it also has some key advantages. For one, pterostilbene's unique structure makes it more oil-soluble than resveratrol, which increases its absorption and cellular uptake while reducing the rate of elimination from the body. Research has shown that pterostilbene has seven times the half-life of resveratrol and has a greater bioactivity in reducing the effects of oxidative stress. The two stilbenoids are synergistic, however, with improved ability to protect against oxidative damage when taken together. Our Pterostilbene Plus with Resveratrol features 50 mg of 99% pure trans-pterostilbene to promote heart health and support healthy blood pressure levels. Combined with 250 mg of trans-resveratrol, it delivers a potent one-two punch to knock out free radicals and protect your cardiovascular health.
