Mitochondria are the powerhouses of every cell. They turn our food into usable energy. Mitochondrial function can be disrupted by taking common prescription drugs which prevent mitochondria from communicating with the cell's nuclear genome.
Statins and blood pressure medications interfere with mitochondrial energy levels. This might explain the cause of muscle fatigue when taking these drugs.
Some drugs actually increase mitochondrial function and decrease toxic load. One of these compounds is found in Green Tea. That would explain why Green Tea has for a long time been anecdotally credited with normalizing blood sugar and increasing energy levels. Type 2 diabetes is associated with a decrease in mitochondrial genetic expression and may be helped by regularly drinking Green Tea.
