How to reconstitute Glutathione
Glutathione is sold as a freeze-dried powder, most often in 200 mg, 600 mg, 1,500 mg vials. Add bacteriostatic water, let it dissolve without shaking, and the concentration is the vial amount divided by the water: 600 mg in 6 mL is 100 mg/mL. On a U-100 insulin syringe one unit is 0.01 mL, so each unit carries 1,000 mcg, and a 200 mg dose is 200 units.
Compounded glutathione injections are commonly 100 to 400 mg per dose; volumes are large, so a 3 mL syringe is usual. Nothing on this page is a dosing recommendation; the calculator converts a dose you already have into syringe units.
Glutathione doses in syringe units (600 mg vial, 6 mL water)
| Dose | Units | mL | Doses per vial |
|---|---|---|---|
| 100 mg | 100 | 1 | 6 |
| 200 mg | 200 | 2 | 3 |
| 400 mg | 400 | 4 | 1 |
Vial sizes at 200 mg per dose
| Vial | Water | Concentration | Units per dose | Doses |
|---|---|---|---|---|
| 200 mg | 6 mL | 33.33 mg/mL | 600 | 1 |
| 600 mg | 6 mL | 100 mg/mL | 200 | 3 |
| 1,500 mg | 6 mL | 250 mg/mL | 80 | 7 |
The dose column is in mg. Doubling the water halves the concentration and doubles the units per dose; the number of doses in the vial never changes. If a dose comes out under 5 units, use less water so it is easier to measure. If it exceeds the syringe, use more water or a bigger syringe.
Worked example
600 mg / 6 mL = 100 mg/mL = 100,000 mcg/mL. One unit = 0.01 mL = 1,000 mcg. 200,000 mcg / 1,000 mcg per unit = 200 units. The vial holds 600,000 / 200,000 = 3 doses, which at 3 per week is about 7 days.
