What it does
For the afternoon fog most of us learn to live with: reading the same paragraph twice, losing the thread. Refocus is a daily capsule for focus and mental clarity, made with L-theanine (the amino acid found in tea), bacopa and a small, measured amount of methylene blue.*
Inside Refocus
Clear, steady focus.

The research behind each ingredient
Bacopa
In research
Delayed word recall and attention scores improved compared with placebo.[9]
- Study:
- Randomized, double-blind, placebo-controlled trial
- Who:
- 48 adults
- Dose studied:
- 300 mg a day
- How long:
- 12 weeks
The extract was standardized differently from ours. The most common side effect was stomach upset.
In research
Learning new words and recalling them later improved compared with placebo.[10]
- Study:
- Randomized, double-blind, placebo-controlled trial
- Who:
- 81 adults
- Dose studied:
- 300 mg a day
- How long:
- 12 weeks
A different bacopa extract from ours. Participants reported more digestive side effects than with placebo.
In research
Speed of visual information processing, learning rate and memory consolidation improved compared with placebo.[11]
- Study:
- Randomized, double-blind, placebo-controlled trial
- Who:
- 46 healthy adults
- Dose studied:
- 300 mg a day
- How long:
- 12 weeks
A different bacopa extract from ours. The strongest effects appeared at 12 weeks, not at 5.
In research
Retention of newly learned information improved compared with placebo.[12]
- Study:
- Randomized, double-blind, placebo-controlled trial
- Who:
- 76 adults
- Dose studied:
- 300 mg a day
- How long:
- 12 weeks
A different bacopa extract from ours. Learning rate, attention and short-term memory did not change.
Suntheanine® L-theanine
In research
Sleep quality scores improved compared with placebo. Stress-related scores and some measures of attention improved during the L-theanine period.[13]
- Study:
- Randomized, placebo-controlled crossover trial
- Who:
- 30 healthy adults
- Dose studied:
- 200 mg a day of Suntheanine®, the same form and amount as Refocus
- How long:
- 4 weeks
Cognitive changes were not significant against placebo overall. The ingredient maker supplied the product and employs two of the authors.
In research
A single dose shortened reaction time on attention tasks and improved working-memory accuracy.[14]
- Study:
- Randomized, placebo-controlled trial
- Who:
- 69 adults
- Dose studied:
- About 100 mg a day
- How long:
- 12 weeks, plus single-dose tests
Half the amount in Refocus. Twelve weeks of daily use did not change attention scores.
In research
Compared with placebo, L-theanine eased the rise in heart rate and in a salivary stress marker (s-IgA) during the task.[15]
- Study:
- Double-blind, placebo-controlled crossover study
- Who:
- 12 adults
- Dose studied:
- A single serving of L-theanine
- How long:
- One session with a demanding mental arithmetic task
A small, one-off laboratory study. Two authors worked for the ingredient maker.

The science
The science behind Refocus
How methylene blue relates to the way your cells make energy, and what the research shows.
Methylene blueHelps shuttle electrons
from foodCellular
energy
Methylene blue, first made in 1876, can carry electrons along the chain your cells use to make energy, which is why researchers study it for cellular energy.
What the research shows
- Laboratory research describes how methylene blue can carry electrons along the mitochondrial energy chain.[1]
- In a randomized, placebo-controlled brain-imaging study of 26 healthy adults, a single dose was followed by more activity in brain regions linked to attention and memory, and better short-term memory scores.[8] That study used a single 280 mg dose, about 20 times the 14 mg in a 2-capsule serving of Refocus, so its results can’t be assumed for a daily supplement.

How to take it
- 1
1–2 capsules with breakfast
Take 1 to 2 capsules daily, preferably with food, or as directed by a healthcare professional. Take it first thing in the morning, with breakfast, and avoid late evenings so it doesn’t get in the way of your sleep.
- 2
Every day, for the whole jar
One jar is 30 days. Give it the full 30 days before deciding how it works for you.

Don’t be surprised by blue
Your urine may turn blue or green. This is harmless. It is simply the methylene blue leaving your body.
Your first order arrives in our gift box with a pocket pill case, so a week of capsules fits in a bag or pocket.

FAQ
One capsule or two?
The label allows 1 to 2 capsules a day with food. You can start with one and move to two. Each capsule has 7 mg of methylene blue, so the full 2-capsule serving has 14 mg. At two capsules a day, one jar lasts 30 days; at one a day, up to 60.
What is methylene blue?
Methylene blue is a compound first made in 1876. Researchers have studied it for its role in how cells produce energy inside the mitochondria. Each NueBlū formula pairs a measured amount with well-known ingredients such as L-theanine, CoQ10 and NAC.
How long until I notice anything?
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.
Is this a subscription?
Only if you choose one. A one-time order is one jar with one payment, and nothing renews automatically. If you subscribe instead, you choose how often a jar is delivered, and you can skip or cancel anytime.
