Vinpocetine is well researched and proven to enhance our brain function. It is generally less unheard of, as compared to other brain boosters such Ginkgo Biloba. Vinpocetine increases blood flow and oxygenation to our brain. In the process, more nutrients are accessible by our brain as well. The benefits are improved memory, increased alertness, sharpness and concentration power, improve mental energy and helps to lift brain fog. It can reverse some of the symptoms of neurodegenerative diseases. Personally, I take 4 daily so this bottle can last for a month. As for the price, it’s fairly expensive as compared to other brands. This is highly recommended to take this product with other brain enhancers such Ginkgo Biloba, Gotu Kola, Rosemary for additional benefits (as compared to standalone). The capsule is small, easy to swallow and is made of gelatine (not suitable for vegetarians). The product also does not contain magnesium stearate which the reason I try this brand. It does contains rice flour as filler as there is only 10mg of vinpocetine. Check out my page for more reviews!
