The Blu — methylene blue sublingual
Everything you need to know about your sublingual methylene blue — mitochondrial support you can take at home.
What is The Blu?
The Blu is a sublingual (under the tongue) methylene blue formula designed for at-home use. Same mitochondrial benefits as the IV — in a convenient daily format.
Methylene blue supports your mitochondrial electron transport chain — the process your cells use to create energy. Sublingual delivery allows faster absorption than oral capsules, getting into your bloodstream quickly and efficiently.
What methylene blue does
Cellular energy and cognitive support in every drop.
Mitochondrial Support
Supports the mitochondrial electron transport chain — helping your cells produce energy more efficiently, even when normal pathways are impaired.
Brain Clarity
Crosses the blood-brain barrier for direct cognitive support. Many patients report sharper focus, better memory, and reduced brain fog.
Antioxidant Defense
Acts as an antioxidant, protecting cells from oxidative damage. Supports neuroprotection and cellular longevity.
ATP Production
Supports ATP production — the energy currency every cell needs. More efficient energy production means better performance across your entire body.
How to use The Blu
Simple daily use — takes less than a minute.
Place Drops Under Tongue
Place the prescribed number of drops under your tongue as directed by your provider.
Hold for 30–60 Seconds
Hold under your tongue for 30–60 seconds before swallowing. This allows sublingual absorption directly into your bloodstream.
Take in the Morning
Take in the morning for best results. Methylene blue may be energizing — taking it later in the day could affect sleep.
Expect the Blue
Your lips, tongue, and mouth will temporarily turn blue. Blue-green urine is also normal. Both are harmless and expected.
What to expect
Benefits build with consistent daily use.
First Use
Some notice improved focus and alertness within hours. Your cells are getting immediate mitochondrial support.
Week 1–2
More consistent energy and mental clarity. The cumulative effect of daily mitochondrial support begins to show.
Month 1+
Cumulative mitochondrial support. Sustained improvements in energy, focus, and cognitive performance.
