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.

Good Mental Boost - helps dopamine balance up in the Hippocampus in the Brain
Verified purchase
I use ONLY 10mg, taken with Trans-Resveratrol 50mg. Both reduces ROS. But I don't use it on exercise days because I want a little oxidation for potential muscle growth on training nights. Taken with 1 tsp coconut fat in the EVENING 30mins AFTER taking 500mg Agmatine sulfate in water ON AN EMPTY STOMACH 1 HOUR AFTER DINNER.. Honokiol 200mg at the same time for sleep.

Nutricost Pterostilbene 100mg,120 capsules
Verified purchase
Nutricost Pterostilbene 100mg is a premium antioxidant,from a well known, trusted brand,that is using quality ingredients at a good price. Pterostilbene is more bioavailable than resveratrol and I can feel the difference in my mental clarity and overall energy throughout the day. Pterostilbene is improving insulin sensitivity by regulating glucose metabolism, activates AMPK pathway and reduces oxidative stress.

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!|

I'm taking 100mg daily - I open the capsule and mix into my yoghurt. You need to take this with a fat for better bioavailability. I also take it with bioperine. Better than resveratrol.

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.
