In your fitness journey, taurine has been known to have anti-neurotoxic and anti-inflammatory effects meaning you’ll feel less fatigued during and after your workout.


Glucose, often synonymous with sugar, is one of our body’s main energy sources. Glucose can be commonly found in most of the carbohydrate-based food we consume. In your pre-workout, glucose can help add energy and elevate blood sugar levels for an active workout. That said, increased glucose levels can result in high blood pressure.
