I have been taking OGF for 15 years. I believe that supplementing with OGF has resulted in an overall health that I would not have otherwise enjoyed. I am not finding out that it has more benefits than I first thought like enhancing longevity and better immune support.

Glutathione Ingredients Diagram

NAC is a precursor to glutathione, a potent antioxidant in the body. It helps support the immune system by replenishing glutathione levels, which plays a crucial role in neutralizing free radicals, reducing oxidative stress, and enhancing immune cell function.

Vitamin C is a well-known immune-boosting nutrient. It supports the immune system by promoting the production of white blood cells, which are essential for fighting off pathogens. Additionally, it acts as an antioxidant, protecting immune cells from damage and enhancing their overall function.

Alpha Lipoic Acid is a powerful antioxidant that helps protect immune cells from oxidative stress. It plays a role in cellular energy production and helps regenerate other antioxidants like glutathione and vitamin C, further supporting the immune system's function.

L-Glutamine is an amino acid that plays a vital role in immune cell regulation and function. It helps strengthen the integrity of the gut lining, enhancing the body's defense against harmful pathogens. L-Glutamine also supports the production of immune cells, promoting an efficient immune response.

Quercetin is a flavonoid with potent antioxidant and anti-inflammatory properties. It helps modulate the immune system by reducing inflammation and supporting immune cell activity. Quercetin has been shown to enhance the body's natural defense mechanisms, making it beneficial for overall immune health.

Milk Thistle contains a compound called silymarin, which exhibits antioxidant and anti-inflammatory properties. It aids in liver detoxification, promoting a healthy liver function. A healthy liver is crucial for proper immune system function as it helps eliminate toxins and supports overall immune health.

Glutathione Boosts Mental Clarity

Brain Fog

Decreases Brain Fog As your body's most important antioxidant, Glutathione is very important in the overall health and peak function of the brain, including memory and mental acuity. The brain consumes more calories per ounce than any other organ in the body, and as a result, is also responsible for an equally high level of free radical formation. In order for the brain to function at optimum efficiency there needs to be adequate levels of Glutathione available to quench and eliminate these free radicals as quickly as they are formed. Daily supplementation with Original Glutathione Formula™ may assist your body in maintaining healthy levels of Glutathione, providing your brain with the resources it needs to operate at optimal efficiency.
Glutathione Boosts Energy Levels

Energy Levels

Increases Energy and Endurance Loss of energy and stamina, though often age related, can also be brought about by poor nutrition, lack of proper sleep, elevated levels of physical or emotional stress and depleted Glutathione in your body. Glutathione increases your cells efficiency; The more efficiently each cell in your body operates, the more ATP (energy) it can produce, the more ATP your cells produce, the more energy you will have available. Daily supplementation with Original Glutathione Formula™ may help to restore normal healthy levels of Glutathione, restoring your ability to work and play at full capacity.
OGF Activates Nrf2

Reduces Effects
of Aging

Reduces Effects of Aging Like a microscopic workforce of a million particles, your cells come in a variety of sizes and each has a unique function. Start by taking a deep breath and exhaling. Through your lungs the oxygen particles have been absorbed and transferred to blood cells, which carry the oxygen to every part of your body that needs it, including major organs, the brain, muscle tissue and nerves. And that breath is just one of hundreds of thousands of similar functions or exchanges that happen at the cellular level each day, to keep you thinking, moving, eating, digesting and in good health. Just as your cells are able to carry oxygen and other materials to your body through your blood stream, they are also susceptible to carrying negative elements, such as oxidants that attach to healthy cells and impede their functioning.
