Fresh Mint, 10mg Per mL

USP Grade Methylene Blue (Fresh Mint)

4.4 (16 reviews)

Methylene blue has one job: help your cells make energy.* Ours is USP grade — the highest purity standard you can buy — with 10 mg in every 1 mL dropper. One drop is 0.5 mg, so you can dose it your way, drop by drop. It supports brain function, memory, and clear thinking, with antioxidant support built in.* Every batch is third-party tested, it's made in the USA, and it tastes like fresh mint with a whisper of vanilla. No harsh bitterness. No stimulants. Just drops.

Why a Tincture?

Drops let you pick your dose. One drop is 0.5 mg and a full dropper is 10 mg. Start small, find what feels right, and adjust drop by drop.

Ingredients & Allergies

One active ingredient: USP-grade methylene blue, 10 mg per 1 mL. The rest is just water, organic glycerin, mint-vanilla flavor, citric acid, and a touch of stevia. Free of wheat, gluten, soy, tree nuts, eggs, milk, shellfish, and corn — plus non-GMO and vegan.

Natural Flavors, Citric Acid, Organic Stevia Rebaudiana Extract, Potassium Sorbate.

How do I take this?

Shake well, then take 1 mL (20 drops) on your tongue or in water or juice — mornings are best. New to methylene blue? Start with a few drops and work up slowly. Skip it if you're pregnant, nursing, or on medication — especially SSRIs, SNRIs, or MAOIs.

Science & Certifications

USP grade means it meets the United States Pharmacopeia purity standard — the highest commercially available. It's made in the USA in a cGMP-certified facility, and every batch is third-party tested with a published report.
