There are approximately 75 trillion cells in the human body. Each of these cells has its own unique purpose and function within the body. If for any reason these cells become malnourished or otherwise impaired, our health rapidly deteriorates. The health of all living organisms begins at the cellular level.

Each cell has an organelle, which is a subunit of that cell and has its own specific function to help the cell. Those organelle cells all contain mitochondria, often referred to as the "powerhouses" of the cell because these supply the chemical energy our cells need to function and regulate our metabolism through the conversion of energy. Every single cell in all organisms has metabolism. This is what gives the energy to provide all body functions, including brain function, heartbeat, respiratory and circulation. As nothing can survive without metabolism, it is necessary that we keep our metabolism functioning as well as possible.

This is why glutathione is important. Glutathione is a peptide that normally occurs in the tissues of animals and plants. It plays a direct role in the neutralization of free-radicals, which are the things that cause illness, problems with aging and DNA. It also detoxifies the many carcinogens and neurotoxins that impact our health, including from lead, mercury and arsenic.

Glutathione therefore plays a fundamental role in metabolic reactions, protein synthesis and DNA repair. Every single cell in our bodies and body functions is affected by the glutathione system, including the central nervous system, gastrointestinal system, immune system and lungs. Glutathione may even reduce the risk of cancer and aid in repairing traumatic injury.

To keep our glutathione system running well and performing all of these fundamental tasks, Vitamin D and milk thistle should be incorporated into the diet as these boost glutathione production. Many of the immunological claims about Vitamin D are due to its role in making glutathione and its role in preventing cancer. Vitamin D also helps the body maintain blood sugar levels and builds strong teeth and bones. The benefits of milk thistle are also enormous, especially in terms of how it heals and supports the liver. Anyone who wishes to improve his health should consider eating foods rich in Vitamin D or taking a Vitamin D and/or milk thistle supplement. Foods that are high in Vitamin D include: Wild salmon, mackerel, herring, catfish, sardines, cod liver oil, organic egg yolks, shitake mushrooms and button mushrooms. Daily doses of sunshine can also boost Vitamin D production.
