Polygala tenuifolia Capsules | 100mg | 180 Count | 20:1 Extract | Yuan Zhi | Promotes Cognitive Function, Learning and Memory | Supports Healthy Stress Levels | Adaptogen Supplement

NootropicsDepot is provably the best supplement company in the industry... Want proof? Ask other companies for their COA's and advanced testing. Only one company has the integrity to publish all of their results - that's Nootropicsdepot (ND). If it's not ND, it's an inferior product. I will only take ND supplements because I have seen the LACK of testing that goes into other brands, (which I won't name here, but unfortunately includes almost every other supplement company in the market). If you care about your health, your families health, the integrity of a company and the purity of its product, NootropicsDepot is the only choice.As for this particular product, I noticed an almost immediate positive result within 45 minutes after taking it on an empty stomach. I noticed greater clarity and recall, which has continued to improve with daily usage. My cognition seems sharper, I type faster and more accurately and I feel as though I am learning quicker. I have noticed fantastic quality across all of the ND supplements I have tried. For those that care about their health, this is the only option.

This product is great for relieving stress

Great

very good for you

I think it helped my sleep.. let's see. I do have a pretty serious sleep problem, likely coupled with anxiety

Mood showed definite signs of improvement. Worth giving a try if you are curious. I’ve bought numerous products from nootropics depot and I can say that the quality is always great

First and foremost, Nootropics Depot is an exemplary brand that utilizes third party testing and produces only the highest quality supplements. I’ve trusted them for years (I am a dietetics researcher, if that lends my opinion any credit).As for the supplement itself, Polygala tenuifolia (sometimes referred to as Yuan Zhi) is one of the most potent ‘nootropic’ supplements I’ve tried. A good amount of scientific evidence supports polygala as an antidepressant, anti-anxiety, and cognition improving plant. Clinical studies show evidence of reuptake inhibition of serotonin, dopamine, and norepinephrine. Polygala has been shown to help mild depression very quickly, as well as chronic stress. Another mechanism of action seems to be related to NMDA antagonism (similar to newly available ketamine therapy). Polygala also shows evidence of increasing BDNF, or brain-derived neurotrophic factor, increasing cognition, memory, and anti-inflammatory neuroprotection. I recommend trying the supplement, it seems to have helped quite a bit with brain fog and chronic anxiety.

I would've loved to have tried this product longer to see if they would work for me, but it gave me horrible headaches.
