## 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.
