High Quality, and Convenient package Size

Nutricost’s Pterostilbene has excellent, safe ingredients, with a composition of only rice flour as a filler. I love that it’s third-party tested for quality and purity. The 120-serving size of 100 mg is convenient and perfect for regular use. I open the capsules and consume just the contents, which have a neutral taste, making it easy to incorporate into my diet. The benefit of this supplement is its support in managing oxidative radicals. Highly recommended!

Good value and high dose!

Verified purchase

This is a good option if you want a 100mg dosage, will last for 4 months to ends up being a very good value compared to other options. 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.

Powerful Antioxidant Great for Focus, Energy, and Longevity

Verified purchase

I’ve been taking Nutricost’s Pterostilbene for about a month and I’m very impressed with the quality. Pterostilbene is a natural compound similar to resveratrol but more bioavailable and longer-lasting in the body. It supports cellular health, antioxidant defense, and healthy aging. Since starting it, I’ve noticed clearer focus, steadier energy, and overall better mental sharpness. The capsules are small, easy to swallow, and have no taste or side effects. I like that each capsule contains a full 100 mg dose perfect for stacking with NAD+ boosters or other longevity supplements. It’s also great for cardiovascular support and oxidative stress protection. The bottle arrived quickly from iHerb, sealed and fresh. Nutricost delivers solid value here clean ingredients, no fillers, and a large 120-capsule supply. Definitely worth trying if you’re building a well-rounded anti-aging or brain-health stack.

Nutricost’s Pterostilbene is high quality and clean composition - made just rice flour as filler ingredient. The 120 capsule size is really convenient and lasts a long time. I like to open the capsules since the powder has a neutral taste, which is a nice benefit for mixing into my diet. Good quality and third-party tested, so I feel comfortable using it.

This is one of the best vitamin C supplements I've tried! The absorption is noticeably better thanks to the liposomal form, and it's very gentle on the stomach—no discomfort or acidity at all. I felt a clear boost in my immunity after just a few days of use. The antioxidant benefits are real, and I love that it's high quality with clean ingredients. The taste is surprisingly pleasant, and the individual packets are super convenient for travel. Great mg dosage and well thought-out package size. Highly recommend!|
