Here are the roles of magnesium complex in these areas:Magnesium is an important element in maintaining bone structure and function. It is involved in a variety of biochemical processes related to bone health:Calcium and phosphorus metabolism: Magnesium helps the absorption and utilization of calcium and phosphorus, two major minerals that make up bones. By promoting the balance of these minerals, magnesium helps maintain bone density and strength.Sleep QualityNervous System Regulation: Magnesium can help relax nerves, reduce tension and anxiety, and thus improve sleep quality. It promotes sleep by acting on neurotransmitters in the brain, such as gamma-aminobutyric acid (GABA).Muscle FunctionEnergy Metabolism: Magnesium is involved in the energy metabolism process within cells, especially the generation and utilization of ATP.
