Blue Liquid 12-Pack

⚠️ Important Safety Notice: Do not use if you are on SSRIs, SNRIs, MAOIs, or any serotonergic medication. Do not use if pregnant or nursing. Not for children. Methylene blue is a potent MAO-A inhibitor with documented interactions with serotonergic drugs; combining them creates a risk of serotonin syndrome. Review the full adverse medications list before use and consult a doctor if you are on any medications. Taking in the evening may affect sleep.


This is a case of 12 bottles of Blue Boost Liquid, the same formula sold as a single bottle. Each bottle holds 120 mL (about 4 fl oz). Blue Boost Liquid is methylene blue in liquid form, dissolved in purified water, at 1% concentration (10 mg per mL), in an amber plastic bottle with a graduated dropper so you can measure exactly what you take.

What's in each bottle of Blue Boost Liquid:

✔ USP-grade Methylene Blue, 1% (10 mg per mL): our manufacturer states in a signed attestation that the raw material conforms to the United States Pharmacopeia (USP) monograph for identity, purity, and contaminants. USP grade here means conformance to the monograph, not USP certification or endorsement

✔ Purified water: alcohol-free

✔ 12 bottles, 120 mL each: amber plastic bottle with a 0.05 mL graduated dropper; about 1,200 mg of methylene blue per bottle

Quality & Manufacturing:

✔ Our manufacturer states in a signed attestation that batches are tested for identity, potency, heavy metals, microbial limits, and residual solvents. Third-party lab reports for our capsule formulas are available at nutricel.store/pages/certs

✔ Manufactured in the USA in a GMP certified facility (21 CFR Part 111)

Dosage: At 1%, each drop contains about 0.5 mg of methylene blue (based on 20 drops per mL), so amounts can be measured in small increments. Use the graduated dropper for the most precise measurement.

VolumeMethylene Blue
1 drop (~50 µL)~0.5 mg
5 drops (~250 µL)~2.5 mg
10 drops (~500 µL)~5 mg
20 drops (1 mL)10 mg
120 mL (about 4 fl oz)~1,200 mg total

Drop volume varies with viscosity, dropper angle, and squeeze pressure.

Will it stain? Methylene blue stains surfaces, fabric, and skin on contact. Use the dropper carefully over a sink and rinse any spills immediately with water.

How should it be stored? Store at room temperature in the original amber bottle, away from direct sunlight and heat. Keep tightly sealed. Do not freeze. See the best-by date printed on each bottle.

Capsules or liquid? Capsules (for example Blue Boost, 12mg) are simpler: one capsule, a fixed amount, no measuring, no staining. The liquid is an option if you want to measure smaller amounts than a capsule contains or mix it into water or juice. If you are new to methylene blue, capsules are the easier format to start with.
