Double Wood Supplements Pterostilbene Review

Pterostilbene is a methylated stilbene molecule that is very similar in structure and effects to resveratrol, but is much more well absorbed when taken orally and has more potent antioxidant benefits. Pterostilbene supplementation may help support cognitive function, healthy cholesterol levels, and cardiovascular health. The product is marked Soy-Free, Gluten-Free and Non-GMO. The benefits section describes Pterostilbene as a potent antioxidant that may bind to PPAR receptors and support the production of the compound, may help support cognitive function and brain cell health, may support a healthy body and mind during healthy aging, and is manufactured right here in the USA from globally sourced ingredients. Double Wood states that its products are pure, potent, deliver exceptional value and are backed by careful sourcing and rigorous third-party testing. The directions state that commonly recommended dosages vary between 100 and 200 mg per day, that 250 mg per day has been found to cause no signs of toxicity and no significant adverse side effects, and that Pterostilbene is fat soluble and best taken with food. It also notes that doses as high as 3000 mg per day have failed to show signs of toxicity in animal models, but due to a lack of research at high doses in humans it is not recommended to exceed 600 mg per day. The certificate of analysis for lot 2530103 lists a capsule weight of 395 mg against a 375 to 415 mg specification, pterostilbene at 98.24 mg against a 90 to 125 mg specification, passed disintegration, heavy metals and microbial tests. The product is offered as a subscription or one-time purchase, with a backorder notice for the one bottle option.
