antioxidant.

Glutathione sits at the center of cellular detox — neutralizing free radicals, escorting heavy metals out, and protecting the mitochondria. This formula delivers L-Glutathione with the cofactors the body needs to regenerate it.

PROFESSIONAL GRADE · 60 CAPSULES · L-GLUTATHIONE · SELENIUM · QUERCETIN

GLUTATHIONE

80 mg L-Glutathione per capsule

Feed the master pool.

L-Glutathione is the cell's primary defense against oxidative stress and heavy-metal load. Direct supplementation helps maintain intracellular levels that decline with age, stress, and genetic methylation variants.

COFACTORS

7 recycling nutrients

Regenerate, don't just replace.

Glutathione gets oxidized as it works. Selenium, riboflavin, B6, zinc, and vitamin C are the cofactors that reduce it back to active form — so the same molecule keeps working shift after shift.

DAILY DOSE

2 capsules daily maximum

One to two, with or without food.

Adults take one to two capsules daily. Taurine and quercetin round out the stack — adding antioxidant breadth and helping stabilize mast cells during detoxification.

MAY BENEFIT

Detox is an
intracellular job.

Cellular detoxification

Glutathione conjugates heavy metals, pesticides, and synthetic estrogens for safe excretion.

Free-radical defense

The thiol group in glutathione is the cell's frontline scavenger of reactive oxygen species.

Liver & biliary support

Phase II liver detoxification runs on glutathione conjugation — the bottleneck for clearance.

Immune function

Lymphocytes depend on glutathione to mount oxidative bursts without damaging themselves.

Cardiovascular resilience

Oxidized LDL drives arterial stress; glutathione helps maintain redox balance in vessel walls.

Healthy aging

Intracellular glutathione declines with age — direct repletion supports the biochemistry of longevity.

Questions

Frequently asked.

Why take oral glutathione when the stomach is supposed to break it down?

Research over the last decade has revised that view. Oral L-glutathione paired with the cofactors needed for synthesis and recycling — selenium, riboflavin, vitamin C, B6, zinc — raises systemic glutathione markers over time. The formula is built as a complete recycling system, not a single bolus.

Who should consider this formula?

Adults with heavy toxic-load exposure, MTHFR or GST variants that impair detoxification, chronic inflammation, or compromised liver function. It's also a common choice for practitioners working with patients whose aging, immune, or cardiovascular markers suggest elevated oxidative stress.

How does this differ from liposomal glutathione?

Liposomal delivery encapsulates glutathione in phospholipids for faster absorption and is useful when rapid repletion is needed. This capsule is a more comprehensive formulation — glutathione plus the B-vitamin, selenium, and zinc cofactors that keep the molecule regenerating between doses.

Can I take it with other supplements?

Yes. Glutathione Ultra pairs well with methylation support (SAM-e, methylfolate, B12) because methylation and glutathione synthesis share upstream biochemistry. Many practitioners also pair it with mitochondrial formulas like Mito Cell PQQ.

When will I feel a difference?

Glutathione supports subtle biochemistry rather than delivering an obvious kick. Many people report cleaner energy, steadier skin, and fewer reactive symptoms within four to eight weeks of consistent use. Patients with meaningful toxic load may notice changes sooner.

Is it safe during pregnancy or while breastfeeding?

Consult a healthcare practitioner before use if you are pregnant, lactating, or taking medications. Detoxification support is best managed with professional oversight during these periods.

Methylation and the immune system: how one cycle shapes inflammation

The methylation cycle is not just a mood and detox system — it quietly regulates how your immune cells turn on, turn off, and resolve inflammation. Here's the connection.

Homocysteine is the single most useful functional marker for methylation status. Here's what it is, why MTHFR carriers watch it closely, and what the numbers mean for cardiovascular, cognitive, and pregnancy risk.
