Glutathione Nasal Spray

Glutathione may support a range of physiological concerns where endogenous levels are depleted due to high oxidative stress, systemic inflammation-related factors, or immune system imbalance. In addition, it plays an independent role in liver detoxification by aiding the elimination of harmful substances. Glutathione may help with the following:

• Cognitive function^1,2
• Lung and airway function^1,2
• Metabolic health²
• Suboptimal immune function^1,5
• Cardiovascular function^1,2
• Ongoing Fatigue-related wellness⁶
• Skin Tone & Overall Skin Health^7,8
• Digestive tract⁹
• Liver detoxification support/Removal of heavy metals from the brain^10,11
• Balanced immune response¹²
• Nerve function¹³
• Gum health¹⁴
• Hallmarks of Aging^15,16
• Mood and mental health^3,4,17
• Post-workout recovery¹⁸

Potential side effects

• Oral forms may cause transient gastrointestinal discomfort
• Excessive glutathione supplementation may impair immune signaling.¹⁹

Precautions

• Individuals with pre-existing kidney disease should avoid high dose glutathione.
• Avoid in pregnant or breastfeeding individuals due to a lack of appropriate data.
• Glutathione may exert a limited mood-regulation effect in patients already on a medication regimen that harnesses anti-inflammatory pathways.³

Handling Requirements

• Keep away from children and pets

Glutathione (GSH) functions primarily as a potent intracellular antioxidant, neutralizing free radicals and reactive oxygen species (ROS) through its sulfur-containing thiol group. GSH is converted to its oxidized form (GSSG) by donating its electrons to neutralize free radicals. By donating electrons, it helps stabilize these reactive molecules and may support cellular defense against oxidative damage to cells. It also plays a key role in detoxification by binding to toxins, rendering them less harmful, and making them more water-soluble and easier for the body to excrete. Additionally, glutathione supports immune function by aiding in the activation and regulation of immune cells. It helps maintain cellular homeostasis by modulating oxidative stress, assisting in protein repair function, supporting mitochondrial function, sustaining DNA integrity, and influencing inflammatory pathways.^1,2,15

Can glutathione impact mitochondrial health?

Mitochondria is a cellular organelle often referred to the "powerhouse" of the cell, regulating a range of functions from energy generation, metabolism and cell survival. Supporting mitochondrial function is the wellspring of efforts to promote physical fitness and longevity at the cellular level. Glutathione plays an important role in the theory of aging that cumulative oxidative stress in mitochondria may determine lifespan. Glutathione helps stabilize the inner mitochondrial membrane, neutralizes reactive oxygen species (ROS) generated by mitochondrial respiration, and maintains mitochondrial DNA fidelity to influence mitochondrial function and cell survival.^2,15,16

What is the role of glutathione in the aging process?

Glutathione levels are believed to rapidly decline after the age of 45. The body has to contend with increased oxidative stress, weakening immunity, and more DNA repair demands as we age. Randomized clinical studies in rodents and older adults show that glutathione acts in concert with the independent actions of two key precursors, glycine and cysteine, to support favorable changes in an array of biomarkers associated with the hallmarks of aging. Biomarkers for endothelial function, insulin sensitivity, intracellular signaling, maintaining DNA integrity, inflammation, metabolic flexibility, mitophagy (recycling old and damaged mitochondria), and cellular senescence (also called "zombie cells" as these cells have lost proper function, harm nearby cells, and do not die off) are all favorably affected. Most of these biomarkers are modulated by glutathione and its precursors at the mitochondrial level. The biomarker changes were shown to correspond with endpoints such as favorable changes in gait and body composition.^15,16
