At the same time, autophagy helps to remove dysfunctional mitochondria, which would otherwise produce harmful reactive oxygen species.

The resulting drop in glutathione production and intracellular glutathione concentrations compromises the mitochondria's ability to scavenge reactive oxygen species (ROS), producing a vicious cycle that drives the progressive increase in ROS - mediated structural damage and its corollary, the progressive decline in energy production and repair that accompanies aging.

As a general rule, the shorter the carbon chain, the more efficiently the MCT will be turned into ketones, which are an excellent source of energy for your body — far preferable to glucose, as ketones produce far less reactive oxygen species (ROS) when they are metabolized to produce ATP.
