Glutathione Nasal Spray: What a Month Costs and What Four Small Studies Found

A glutathione nasal spray is a compounded product, which means a pharmacy prepares it to a prescription rather than a drug maker selling an approved version. Pharmacies may compound glutathione because FDA lists it in 503A Category 1, the substances under evaluation^[1]. Under its interim policy, FDA does not intend to take action against a pharmacy compounding from a Category 1 substance when the policy’s conditions are met^[2]. That policy covers bulk substances that are not a component of an FDA-approved drug^[2].

That policy is an enforcement choice, not a finding that the product works. The rest of this page covers what a spray costs a month, what has been studied, and what to ask before a refill.

What a month of spray costs

Spray prices run from $83 to $249 a month across 16 sellers, each counted once at its lowest monthly spray price, and they were read through September 2026. That is a small market, so a single seller changing its price can move the typical figure.

The two figures price different amounts of medicine, so they cannot be compared directly. A seller that states the milligrams per spray and the sprays per day lets you convert both to a cost per milligram with the cost-per-mg calculator. The injection route is priced in detail in glutathione injection cost, and clinic drips in glutathione IV cost.

Four studies, in the order they were published

Almost everything known about glutathione sprayed into the nose comes from one team, led by the same first author, working mostly with people who have Parkinson’s disease. Read in sequence, the studies show how far the evidence has come and where it stops.

The 2013 survey went to people drawn from a pharmacy database who had been prescribed the spray between 2009 and 2011, and its authors wrote that no literature then supported this route^[3]. Of 300 people sent the survey, 70 replied; the most common reasons for the prescription were multiple chemical sensitivity (29) and allergies or sinusitis (25)^[3]. A self-selected survey like this cannot show that the spray works.

The 2015 trial randomized 30 people with Parkinson’s disease to saline, 300 mg a day or 600 mg a day of intranasal glutathione, in three divided doses, for three months^[4]. It was a safety study, and it found no substantial differences between groups in adverse events^[4].

In 2016 the team measured brain glutathione by magnetic resonance spectroscopy in 15 people with mid-stage Parkinson’s disease after one 200 mg dose^[5]. Levels were not higher at 8 minutes but were above baseline at every later time point, for at least an hour^[5].

The 2017 phase IIb trial randomized 45 people to saline, 100 mg or 200 mg three times a day for three months^[6]. Every group improved, placebo included, and neither glutathione dose was superior to placebo^[6]. The authors called for longer and larger studies before any conclusion about lasting benefit^[6].

What these studies do and do not cover

None of the trials studied skin, energy or general wellness uses. They studied people with Parkinson’s disease, at stated doses, for three months at most. Doses on this page are what the trials used, not a recommendation, and no label sets a dose for home use.

Before a refill

Ask the seller which pharmacy compounds the spray, how many milligrams each spray delivers, and how many sprays a day the monthly price assumes. A bottle that runs out early costs more than the price advertised. Then add any membership or consult fee with the all-in monthly calculator. If you are weighing the injection instead, the glutathione all-in list orders injection sellers by the whole monthly charge, and each seller’s price is on the glutathione price board. The same question for NAD+ is answered in NAD nasal spray.
