It is highly effective in providing me energy, great for my daily fitness training. I'm obsessed with this high quality product so much, thank you iherb.
Works good to enhance mood. Important to balance with other neurotransmitters, as L tryptophan boosts only serotonin.
A really really great product! I use it before and after a night out and feel great!
Excellent product and great quality. Ingredient profile is good and has helped my sleep and wake up feeling better
This has worked for me I take it before bed and helps me sleep
Good product, great quality, I will order more. I recommend it for purchase.
It's pretty hard to tell with supplements like these whether they are working, but I do think I detected an improvement. They seem good quality.
It helps to have a better night sleep.
Great for stress relief and mood regulation. Takes the edge of things somehow. Will buyy again.
I think this is a good product. It helped me to sleep. But the capsule is a little too big for me to swallow comfortably. I will try to finish the bottle by opening the capsule and mixing it with water. I am 70 and maybe my throat is smaller or more sensitive than most people, so others might not have this problem at all. I suggest that they put it in a smaller capule with a serving size of 2 rather than 1. Again, a great product, but the size, though not huge, was slightly too big for me.
