Swanson Pterostilbene 50 mg Review
Swanson Pterostilbene 50 mg is offered as 30 veggie capsules, with one veggie capsule per serving and 30 servings per container. The page describes pterostilbene as a phytonutrient similar to resveratrol but with enhanced absorption. It is presented as a way to support long term metabolic health and vitality and to deliver antioxidant defense against free radicals. The product page explains that resveratrol was discovered in grapes, which led researchers to examine similar compounds in other foods. Pterostilbene is described as an antioxidant phytonutrient found in certain berries, especially blueberries. The page states that, though related to resveratrol, pterostilbene differs in key ways: it appears to be better absorbed and delivers stronger metabolic support. In other words, more of it gets into the system and remains active longer. Preliminary research is said to suggest that pterostilbene offers antioxidant benefits that may be both independent of and complementary to those of resveratrol. The page says this means pterostilbene offers enhanced defense against free radicals that form in the body as a result of exercise, stress or exposure to certain daily pollutants. Each serving delivers 50 mg of this antioxidant, which the page links to promoting healthy aging and lasting wellness. The FAQ describes pterostilbene as a naturally occurring polyphenol antioxidant found in blueberries and certain other plants, structurally similar to resveratrol, that helps protect cells from oxidative stress. The page states the product is vegan, vegetarian friendly and non-GMO, but not certified dairy free or gluten free. The Supplement Facts list 50 mg of pterostilbene per serving with no established Daily Value. Other ingredients are hypromellose vegetarian capsule, microcrystalline cellulose, magnesium stearate and silica. Suggested use is one veggie capsule per day with water. The label warns that it is for adults only and advises consulting a healthcare provider before use if pregnant or nursing, taking medication, or having a medical condition. Storage instructions say to keep out of reach of children, not to use if the seal is broken, and to store in a cool, dry place. The page notes that these statements have not been evaluated by the Food and Drug Administration and that the product is not intended to diagnose, treat, cure, or prevent any disease.
