Three formulas, one daily ritual
There is no powder to mix and no program to follow. You take two capsules a day, and one jar lasts a month.
Each formula uses well-studied ingredients such as L-theanine, CoQ10 and NAC instead of stimulants, so there is nothing to crash from.*
Methylene blue is a compound researchers study for its role in how cells make energy. We use 14 mg a day in Refocus and 10 mg in Recharge and Restore, and explain clearly who shouldn’t take it.*
The science, briefly
Inside your mitochondria, electrons from food pass along a chain of proteins to make ATP, the energy every cell runs on. CoQ10 is one of the carriers in that chain. Methylene blue, first made in 1876, can carry electrons along it too, which is why researchers study it for cellular energy.

The people who shouldn’t take NueBlū are listed beside every Add to cart button.
Methylene blue is a compound first made in 1876. Researchers have studied it for its role in how cells produce energy inside the mitochondria. NueBlū uses a small, measured amount per daily serving: 14 mg in Refocus and 10 mg in Recharge and Restore, alongside well-known ingredients such as L-theanine, CoQ10 and NAC.
It isn’t right for everyone, which is why we list the exceptions clearly. Please do not take NueBlū if you take antidepressants or other serotonergic medicines (SSRIs, SNRIs, MAOIs, some pain and migraine medicines, St. John’s Wort or 5-HTP), if you have G6PD deficiency, or if you are pregnant, nursing or under 18. If you take any prescription medicine, check with your doctor first.
Your urine may look blue or green. This is expected and harmless. It’s simply the methylene blue leaving your body.
Everyone is different, so we don’t promise a timeline. Many of our ingredients were studied over several weeks of daily use. We suggest taking it every day with food for the full 30 days of one jar before you decide.
No. A one-time order is one jar with one payment. Nothing renews automatically.
