That is a plant that is used for supplements, and itindeed has stimulatory effects. However, I would not expect much of akick from it. On the other hand, it also has lots of other benefits,such as vitamins (A, C, B, E), minerals (calcium, iron, manganese,magnesium, zinc, and many more) and antioxidants (polyphenol). Add tothis some amino acids, and you get an all-round great supplement totake. You can use it as a pre-workout, but it will also help you getrecovered faster, and fight fatigue among many other things.Personally, I would just get some N2Guard – it has this yerba, andmany ingredients more – for me it is just more convenient to haveit all in one supplement.
