Review: 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
Review: 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.

## Questions & Answers

**Q: If each pill is a 100mg and contains a 20:1 extract, does that mean each pill is equivalent to 2g of Polygala root?**
A: Correct

**Q: Can you feel a difference within several hours of taking it?**
A: It's not a noticeable difference but definitely
feel like it's working. It's almost as if it just makes your day 5-10% better. No, it's not like taking a klonopin. The half life is relatively shorts so you're supposed to take it 3 times a day if that's what you need. I've only been taking it once as needed if I'm stressed because it's supposed to ASSIST you with stress. Remember to avoid dependency of needing it to cope.

**Q: This product uses corn Ethanol (an oxidizer) as an extractor and two fillers. Of the 180 caps,18 grams, 2/3rds are fillers. Is this worth it??**
A: Yes. Nootropics Depot is very reputable, and uses scientifically-backed extraction methods (alcohol in this case), formulas, and is third-party verified. They have quite the following on Reddit. I trust them above most supplement companies. I found this supplement very effective for brain fog, stress, and general mood boosting effects.

**Q: Size of pill compared to a dime?**
A: It's about the length of a dime. A little larger than a vitamin D pill.
