    Science

    The need to know

    Interesting facts

    Glutathione is known as the master antioxidant and is present in every cell in the body.
    Synergy: Glutathione can help to regenerate vitamin C, which in turn can regenerate vitamin E, amplifying the body's overall antioxidant capacity.
    Unlike other mammals humans cannot make vitamin C. Goats, which are of a similar weight to a human around 2-5g per day

    What are the benefits?

    This is not a daily supplement. It is a 14-day protocol designed for specific moments: when you feel something coming on, when you are travelling, when you are under sustained pressure, or when the people around you are getting ill and you would rather not join them.

    The formulation centres on glutathione, which the body uses as its primary internal antioxidant and detoxification agent. Every cell produces glutathione, but production drops under stress, poor sleep, illness and ageing. When levels fall, immune cells lose their ability to respond effectively and oxidative damage accumulates faster than the body can clear it. Supplementing glutathione directly, in a liposomal form that survives digestion, restores the baseline your immune system needs to work from.

    Vitamin C at a meaningful dose supports neutrophil function and antibody production. Quercetin adds antioxidant and anti-inflammatory activity while also enhancing the absorption of other compounds in the formulation. These are not exotic ingredients. They are well-studied compounds that most people do not consume in adequate quantities, particularly during the periods when their body needs them most.

    The 14-day duration is intentional. This is a burst protocol, not a maintenance supplement. You take it when the demand is elevated, then you stop. If you want ongoing immune support, the Longevity Stack provides that as part of a broader daily formulation.

    The science

    This combination of supplements offers a multi-faceted approach to boosting the immune system. It provides a balance of antioxidants, anti-inflammatory agents, and essential vitamins that collectively support and enhance immune function.

    Synergistic Effects:
    Antioxidant Amplification: Glutathione and Vitamin C work synergistically to regenerate each other, enhancing their antioxidant capabilities. Vitamin E can also be regenerated by Vitamin C, creating a potent antioxidant network.

    Anti-Inflammatory Action: Quercetin and Vitamin E have anti-inflammatory properties, which can help to modulate the immune response.

    Enhanced Immunity: Vitamin A is crucial for maintaining the integrity of the skin and mucous membranes, which are the body's first line of defense against pathogens.

    Cellular Support: Glutathione enhances the function of lymphocytes, the white blood cells responsible for immune responses, while Vitamin C supports various cellular functions of both the innate and adaptive immune system.

    Broad-Spectrum Support: The combination covers various aspects of immunity, from cellular health to free radical neutralization and anti-inflammatory action.
