Comments about GNC Probiotics Ultra 25 Probiotic Complex Plus Energy, Capsules, 30 ea:
As a probiotic, this product does its job. But if you have a sensitivity to caffeine or stimulants, you may experience some side effects. I drink about two to four cups of green tea a day (low amounts of caffeine) and occasionally have a diet soda. I don't typically consume a lot of caffeine, but I'm not caffeine-free either. The first day I took the probiotic with energy, I felt a little anxious and experienced a faster heart rate. The second day was a little more intense. By the third day, it felt like an all out anxiety attack. I threw the entire box of pills in the garbage. I'm sure not everyone would have this same reaction, but I just want to share my experience with others who may be a little more sensitive to caffeine. I've since gone back to the regular GNC probiotics (without energy) and everything is just fine. As a side note, I also posted a similar review on the GNC site, but they opted not to post it and only feature the 3-4 star ratings. I don't find that particularly helpful for the customers.
