Muscle twitching is caused by minor muscle contractions in the area, or uncontrollable twitching of a muscle group that is served by a single motor nerve fiber. Muscle twitches are minor and often go unnoticed. Some are common and normal. Others are signs of a nervous system disorder.
Yerba mate has a slight astringent bitter taste due to the high tannin content of the leaves. Researchers have found that leaves from younger plants possess more tannins than leaves from older, more mature trees.
The sweetened variety is even more dulled down and does not appeal to my taste buds at all. My preferred brand is Amazon Planet and the packets contain 100% pure acai. You can get an âenergyâ blend with green tea and yerba mate, but I always stick to the purest form.
