Not the same as Vinpocetine
I tried this because it is hard to find Vinpocetine, which is derived from the great periwinkle. However, Vinpocetine is much more effective and easier to swallow. A daily dose of 30 mg of Vinpocetine is great for the circulation and synapses in the brain. I have taken it 25 years.

Recommended, BUT don't expect much when used by itself & as directed.
No noticeable effects when used by itself and as directed on the bottle. However, when combined with a small amount of caffeine and a little healthy fat (i.e. 1tbl spoon of MCT or a daily dose of fish oil), the positive effects seem to be in line with most of the good peer-reviewed research on periwinkle supplements. Overall, I would probably recommend this particular brand over others out there at the moment.

I like this Product!
I ordered the periwinkle supplement in hopes that perwinkle would be truly 900mg. I think this is a good periwinkle supplement.
