Good questions.
Clearer answers.

A thoughtful product starts with information you can understand. What it is. What’s in the bottle. What to ask before you buy.

01

Ask for the evidence.

Every bottle label carries a lot number. Send us that lot number — or ask before you buy — and we will email the batch report for that specific lot.

What to check in any batch report

  • The lot number on your bottle
  • Identity of the material
  • Measured concentration
  • Contaminant results
  • The test method used
  • Results, not just a grade name
Request the batch report About batch reports

A grade description or clear-looking solution does not replace those results.

02

Know the concentration.

2% w/v means 2 grams per 100 mL — 20 mg of methylene blue per millilitre.

  1. 2%w/v
  2. 20mg per mL
  3. ×30mL in the bottle
  4. 600mg per bottle

Concentration describes the solution only. It is not a dose, and it is not a dosage recommendation.

03

Handle with care.

Methylene blue is a strong dye. Read the label and .

  • Follow the label and safety data sheet.
  • Keep out of reach of children.
  • Protect surfaces from staining.

Health information

The TGA advises: “Do not use oral methylene blue products unless advised or prescribed by a healthcare professional.” Methylene blue can cause serotonin syndrome when taken with some painkillers and SSRI antidepressants. It should not be used during pregnancy, and people with G6PD deficiency may experience haemolysis.

What’s in a
30 mL bottle.

Bottles look alike. Concentrations don’t. Many 30 mL methylene blue solutions commonly contain 150–450 mg. A 2% w/v solution contains 600 mg.

2% w/v is 2 grams per 100 mL, or 20 mg per mL — 600 mg in a 30 mL bottle. Concentration describes the solution only. It is not a dose, and it is not a dosage recommendation.
Is this a supplement or medicine?
No. This product is supplied as a research reagent. It is not a supplement or a medicine, and it is not for human or animal consumption or therapeutic use. The TGA advises: “Do not use oral methylene blue products unless advised or prescribed by a healthcare professional.” Read the TGA safety alert ↗ (opens in new tab)
Do you give directions for use?
No. Bluegum is supplied as a research reagent. This site does not provide dosing, treatment or usage directions, and nothing here is a health claim. Methylene blue can cause serotonin syndrome when taken with some painkillers and SSRI antidepressants; it should not be used during pregnancy; and people with G6PD deficiency may experience haemolysis.
