Good to start or just to try out
Verified Purchase
This is a decent option if you want a low dosage just to try out for a month, otherwise there are better options in the market. Personally I think 50mg is a low dosage but for many its enough for maintenance, I do better with 100mg but it might be because I am a large individual. Pterostilbene may improve cognitive function, lipid metabolism, and glucose regulation and has potential anti-aging effects via SIRT1 activation (similar to resveratrol). It also may support cardiovascular health by reducing LDL oxidation.

Swanson Pterostilben
Verified Purchase
A dietary supplement containing pterostilbene, a natural antioxidant phytonutrient similar to resveratrol, found primarily in blueberries. Unlike resveratrol, pterostilbene may be more readily absorbed and longer-lasting in the body.

Pterostilbene provides enhanced protection against free radicals that form in the body, which reduces inflammation. Has an anti-aging effect, the skin looks better, adds energy in general. The quality is good, the size of the capsules is small, the taste is not felt.

When used in combination with resveratrol
Verified Purchase
As expected from Swanson's pterostilbene, I think it's of the highest quality. (The bottle is quite small since it contains 30 capsules)...I'd like to continue taking it somehow.

Preliminary research suggests that pterostilbene has antioxidant properties that may be independent of and complementary to resveratrol. This means that pterostilbene provides enhanced protection against free radicals that are produced in the body as a result of exercise, stress, or exposure to certain everyday pollutants. Swanson Pterostilbene contains 50 mg of this beneficial antioxidant in each serving to support healthy aging and long-term well-being.

Swanson, Pterostilbene, 50 mg , 30 Veggie Caps
Verified Purchase
This product offers decent and reliable quality with a simple and straightforward formulation that focuses on the core active ingredient without unnecessary complexity The ingredients are clean minimal and easy to understand which can be a positive choice for those who prefer a basic approach to supplementation The capsule size is standard comfortable to swallow and suitable for daily use without discomfort The bottle size is on the smaller side but works well for trying the product or for shorter cycles Overall the quality feels consistent and stable making it a reasonable and practical option especially for users who want a gentle introduction to pterostilbene supplementation.

Cardiovascular Health 50 mg Per Capsule Dietary Supplement Experience the antioxidant support of Swanson pterostilbene for improved well-being. With the discovery of resveratrol in grapes, researchers began studying similar compounds found in other foods. One of the most promising to date is pterostilbene, an antioxidant phytonutrient found in some berries (especially blueberries). Pterostilbene is related to resveratrol but has some key advantages. It is better absorbed and provides more potent metabolic support. In other words, when you take pterostilbene, more of it enters your body and remains active longer. Preliminary research suggests that pterostilbene has antioxidant properties that may be both independent and additive to resveratrol. This means that pterostilbene provides improved protection against free radicals that form in the body as a result of exercise, stress, or exposure to certain everyday pollutants. Swanson Pterostilbene provides 50 mg of this beneficial antioxidant in each serving to promote healthy aging and well-being.
