What is mitochondria and what does it do?

Mitochondria is a kind of organelle, which exists in many cells and is the main place for cells to carry out aerobic respiration. The biggest function is to provide energy for the body. With the increase of age, mitochondrial function is also unbalanced. After the age of 30, people's physical condition is slowly declining. Some time ago, insomnia was serious and energy was poor? Some friends recommend pro, which can not only resist aging against mitochondria, but also improve metabolic aging and delay inflammatory aging. I have eaten it for a month now, which is good for improving energy and sleep.
