Great mood stabilizer
Amber Kilburn✓ Verified Purchase•November 8, 2023
Easy to swallow, not too big. No GI upset noted. I do feel like my mood has stabilized some taking this supplement. I didn't notice much improvement in sleep or pain.
FAST mailing!

I waited a month after buying these to make sure I had adequate time to make an assessment. I started by looking for just l-theanine, but found this mix instead and it is fantastic. I wanted to try this instead of other pills for my ADHD and it certainly works. I have more energy, I have more fun, I'm snacking less, and I get the perfect boost to continue on with my day! I tend to sing when I'm happy and my family has noticed "hey, you're singing again." 🥹🥰
I have found the perfect stack (for me): 1 Gotu Cola first thing in the morning, then 2 True Focus after breakfast, then 2 5-HTP after dinner. It has been *life changing*!! Side note- I've lost 8 pounds in a month without trying! 😀
I am in no way giving medical advice, just sharing what works for me. 😘

Fine. Nothing to write home about. Same product as all the others. Just look at price and quantity to decide which ones you want lol
Feeling cognitively energized while in a good mood, able to cope with stress and prevent negative thoughts in my mind.

This is my 1st time writing a review on Amazon, and I am only doing it because this product actually worked astonishingly well. Although I liked the fact that it is mainly used for people to improve depression, the reason I got this was to help my anxiety which it did. However, I will note that both my mood and anxiety took more than 1 day of doses to start to take in effect. And I noticed when taken at bedtime with melatonin to upgrade the quality of sleep, the supplement was better absorbed in my body and utilized when crossing blood-brain barrier than if I took it without a melatonin supplement.
Advice to users of 5-HTP:
I would highly recommend taking 60mg of 5-HTP instead of the 100. I found that at 100mg starting dose, it would make my cognition very foggy; however, if I opened up the capsule and poured/disposed the powder in the smaller half of the capsule, not only did I have improved mood but because my mind wasn't foggy it sort of made me feel like my cognition was not only significantly enhanced but also energized instead if that makes sense. A second reason I recommend a lower dose in general is because if your brain builds a tolerance to serotonin, then that can become dangerous/problematic in the future due to 'de-sensitization' of the serotonin receptors, making serotonin less effective towards your brain because it is adjusting to a sudden change in serotonin levels in order to maintain a sort of mental homeostasis.
I noticed when my mind was foggy due to the 100mg dose, I would still have the problem of having negative thoughts in my head or pessimistic thoughts. But when I lowered it to about 50-60mg, my mind felt much more clear and I was able to prevent/block myself from the thought of forming those negative thoughts while maintaining an optimistic mood and positive cognitive/behavioral thoughts.
Now I am not entirely sure of the 'energized feeling may be from another supplement I take, but I happen to take arginine and lysine supplements before bed which is important for protein synthesis and prevents a groggy feeling when waking up in the morning. I also take melatonin 1-3mg due to the noisy household environment that occurs in the mornings.
Feel free to ask me any questions or comment on any supplement synergistic combinations to suggest.
