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

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

I have used this for a long time at two capsules per day. It helps me stay calm in a high stress job so I can perform better.

I wanted to try this supplement in an attempt to replace my ADHD meds. Initially I felt no difference day to day. However, after taking this consistently, I've noticed that I wasn't getting frustrated or overwhelmed as easily at work. I really loved this supplement, but I had to stop taking it because it gave me chest tightness and pain. I experimented and took a break from polygala, after including it again in my daily stack the chest pain returned. Really sad that this didn't work out for me.

I find this great for mood boosting, being an anti-depressant, and a overall enhancer to my stack.

I do believe these help my memory and productivity. No flavor as they are small capsules and swallow easily. I had a Chinese herbal doctor give me a mixed blend that had this for a main ingredient (for sleep and memory/cognitive). The doctor's herbs were expensive and I wondered if it would work to just buy the Polygala tenuifolia alone. I think they are definitely effective for the brain and being alert. I am 66 years old and still working. I will continue taking these. For sleep, I don't notice that I sleep better because of them but I only take 1 a day and before lunchtime for my work habits.

Took one pill and it messed up my stomach for over a week: bad cramping and diarrhea.Of course I can’t be sure it was this pill specifically, however, this was the only new thing added into my system & I will not be taking the chance of trying the pill again. I still have not made a full recovery.

Really was expecting something better, gave in 2 separate chances on 2 separate bottles. I’m only giving it a 3 because it does tend to do a little bit of something but in the end it wasn’t worth keeping in my supplement rotation.

Look, I'm only a few days into this, so have limited experience and can't say how soon tolerance might develop etc (my guess would be soon), but I got excited enough to write a review this soon anyway because energy/nootropic supplements literally never effect me. Caffeine doesn't effect me either. Theacrine did once and then quit. I've tried dozens of energy/nootropics and they've done nothing. I take 3-4 of these and I can definitely feel the energy and light mood improvement. I thought the reviews might be fake, because a LOT of nootropic reviews say similar things and they've never worked for me, but I was desperate. Doesn't mean it will work for you, but I can say with confidence, the positive reviews are not fake
