What is Doctor’s Best NAC Detox Regulators? Doctor’s Best NAC Detox Regulators boosts glutathione production in the brain, liver and other organs, supports enzymes that neutralize natural and manmade toxins, and promotes the healthy functioning of numerous important proteins. The three nutrients in this product—NAC (N-Acetyl Cysteine) and the essential minerals selenium, and molybdenum —sustain glutathione. NAC is proven to boost glutathione production. Selenium and molybdenum are essential for facilitating glutathione’s role in supporting energy production, detoxification and other fundamental life processes. How does it work? Doctor’s Best NAC Detox Regulators supports the body’s natural biochemical pathways for neutralizing and excreting toxins. The three nutrients in this product—NAC (N-Acetyl Cysteine) and the essential minerals selenium (Se), and molybdenum (Mo)—sustain glutathione, one of the body’s most important antitoxins, along with many enzymes that use glutathione to neutralize toxins and clear them from the body. These nutrients are all naturally integral to the body’s biochemistry. NAC is the nutrient best proven to sustain the body’s stores of glutathione, which is concentrated in all human cells. Detoxification (“detox”) enzymes in the liver, kidneys, lungs, and other organs use glutathione to bond with (“conjugate”) toxins and thereby make them able to mix into water for excretion (usually via the urine). The detox system has considerable overlap with the antioxidant defense (“antiox”) and redox regulatory (“redox”) systems. The Se and Mo in this formulation each have unique properties that power detox enzymes. Selenium is required by a variety of enzymes that are detox, antiox and redox regulators. Molybdenum is indispensable for enzymes that detoxify sulfur compounds. This product’s combination of NAC plus Se and Mo supports a diverse collection of detox enzymes that dispose of natural and manmade toxins.
