Increased anxiety
8 people found this helpful
While many rave about this product, it wasn't for me. After taking just one capsule, my heart began racing, and I felt anxious—definitely not a calming effect! I'm fortunate I started with a small dose; otherwise, I might have faced serious consequences. I can't conclude it lacks efficacy for everyone, but it's certainly not suitable for all.

Heart palpitations
1 people found this helpful
This product is great value, but I found it increased my energy levels too much, resulting in heart palpitations that are unusual for me. I won't use it again; however, if you regularly consume caffeine, it may suit you.
