Research shows that decreasing the level of deuterium in the tissues and organs is a natural biological process. However, the body’s ability to deplete deuterium decreases as we get older, sicker and get less exercise or sunlight. The easiest way to influence the deuterium content of our body is to decrease the deuterium concentration of drinking water. This can be complemented by consuming deuterium-depleted foods. Animal fats are low in deuterium and burning fat helps your mitochondria make deuterium depleted water.
