Yes. Every gummy is manufactured in an NSF-certified facility in the United States under strict cGMP (current Good Manufacturing Practice) conditions.

Every single batch is third-party lab tested for purity, potency, and contaminants before it ships. We use an independent, accredited laboratory — not our own — so the results are unbiased. Certificates of Analysis are available on request.

NSF certification is one of the highest quality standards in the supplement industry. It means our manufacturing partner has been audited for ingredient sourcing, batch traceability, sanitation, equipment calibration, and product testing.

Made in the USA. Tested by an independent lab. Transparent every step of the way.

At the cellular level, methylene blue acts as an alternate electron carrier inside your mitochondria — the energy factories of every cell in your body. It donates electrons directly to the electron transport chain, helping your cells produce ATP (your body's energy currency) more efficiently — even when normal cellular respiration is stalling.

It's also a powerful antioxidant, cycling between oxidized and reduced forms to neutralize free radicals at the source.

The everyday result: clearer thinking, sustained energy without a stimulant crash, and cellular-level support for long-term vitality. It's one of the most studied molecules in biology — first synthesized in 1876, with over a century of research behind it.

Most customers report a noticeable lift in mental clarity and steady energy within 30–60 minutes of their first gummy. Cumulative benefits — sharper focus, better recovery, more sustained daily energy — typically build over 2–4 weeks of consistent daily use.

Methylene blue is not a stimulant, so you won't get a caffeine-style spike or crash. Think of it less like a jolt and more like turning up the dimmer switch on your cells.

Methylene blue is generally well-tolerated, but you should avoid it (or speak with your doctor first) if you are:

• Taking SSRIs, SNRIs, or MAOI antidepressants (e.g., Prozac, Zoloft, Lexapro, Cymbalta) — combining methylene blue with serotonergic medications can trigger serotonin syndrome, a rare but serious reaction
• Diagnosed with G6PD deficiency (a rare genetic enzyme condition)
• Pregnant or nursing — not enough safety data exists for this population
• Taking blood thinners or other prescription medications — methylene blue can interact with various drugs; always check with your doctor
• Under 18

When in doubt, consult your physician before starting. We're a supplement company — not a substitute for medical advice.

Honest answer: maybe a tiny bit, briefly. Pure methylene blue is famously good at staining things — that's how it earned its name in the first place.

But because our gummies use a precise 5mg dose embedded in a blueberry gummy matrix, the dye is almost entirely absorbed during digestion before it has a chance to color anything noticeably. Some customers report a very faint blue tint on the tongue right after chewing — it rinses off in seconds with water.

Compared to liquid methylene blue drops — which are infamous for blue tongue, blue teeth, blue countertops, and blue fingers — our gummy form is dramatically cleaner. You can take it on the go: no droppers, no spills, no stained shirts.

Each gummy contains 5mg of USP-grade methylene blue, well within the safe range for daily use.

We recommend 1 gummy per day, taken in the morning with or without food. Some users take 2 (10mg total) on demanding days, but we don't recommend exceeding that without speaking to a healthcare provider.

A note on dosing: with methylene blue, less is more. At low doses (1–10mg) it acts as a pro-energy antioxidant. At high doses (50mg+) the effect can actually reverse and become pro-oxidant. Consistency at the right dose beats taking more.
