I was introduced to Red Bull about 5 years ago by my wife. She was into kick boxing at the time and her trainer turned her on to it. I hated it! It tasted like bad cough syrup to me.
Fast foward 5 years and I have the local distributor deliver to me office. Instead of a coffee service we have a Red Bull service. We buy about 5 cases every 2 weeks. I drink 2-3 a day depending on the day.
I was alarmed to read that Taurine was linked to blood clots. I am searching for some info on it right now and not finding anything about that.
This article actually brings out that Taurine is used to treat heart disease.
