Glutathione

The body’s core endogenous antioxidant, researched for cellular protection, liver detoxification pathways, and skin quality.

Typical bottle: 1500 mg

Research note: Glutathione is naturally produced by the body and central to normal cellular function — “detox” framing should not be interpreted as glutathione single-handedly removing toxins; it is one component of the liver, kidney, lung, and GI systems’ broader detoxification function.

What It Is

Glutathione is one of the body’s most important endogenous antioxidants, playing a central role in protecting cells from oxidative stress. It participates in antioxidant defense, liver detoxification, immune function, cellular protection, and mitochondrial health, and helps recycle other antioxidants including vitamins C and E.

Glutathione levels can be influenced by age, stress, poor sleep, intense exercise, alcohol consumption, environmental exposures, and illness — making it a popular research area for recovery, cellular health, healthy aging, and skin quality.

What to Expect

Glutathione is generally approached as a supportive antioxidant protocol rather than something expected to produce a dramatic immediate effect — the primary goal is supporting the body’s existing antioxidant and detoxification systems.

Some report improvements in energy, recovery, skin clarity, and reduced fatigue; these are individual reports and should not be considered guaranteed outcomes.

What to Pair It With

NAD+

Cellular energy production and mitochondrial function complement glutathione’s antioxidant role.

MOTS-C

Mitochondrial function and metabolic signaling provide a complementary cellular-health angle.

GHK-Cu

Collagen production and tissue remodeling complement glutathione’s skin-health research angle.

Reconstitution

Vial

1500 mg

Standard Diluent

5 mL Bac. Water (300 mg/mL)

Alternative Diluent

7 mL Bac. Water (≈214 mg/mL)

100 units = 300 mg (standard mix)46 units = ~100 mg (alt. mix)

Suggested Research Dosing Strategy

Standard Protocol

200–400 mg

Subcutaneous or intramuscular · 3× per week · suggested cycle 4–8 weeks, then ~4 weeks off.

Lower-Dose Daily Protocol

100 mg (≈46 units, alt. mix)

Once daily, 6 days per week · maximum suggested cycle 4 weeks, then ~4 weeks off.

Always calculate the final concentration from the actual diluent volume used — the two protocols above use different reconstitutions and are not interchangeable unit-for-unit.

Administration Notes

May be administered subcutaneously or intramuscularly. A fasted state (roughly 2 hours after the last meal) may be incorporated.

Injection comfort varies with concentration and route — a larger dilution can improve comfort if using a more concentrated preparation.

Adequate hydration and nutrition remain important components of any antioxidant-focused protocol.

Research Considerations

Common everyday factors that increase glutathione demand include alcohol, poor sleep, intense training, chronic stress, smoking/vaping, poor nutrition, environmental exposure, illness, and aging.

Injectable glutathione is only one approach — quality sleep, adequate protein intake, regular (non-excessive) exercise, cruciferous vegetables, and NAC (a glutathione precursor) all support the body’s natural glutathione system as well.
