The gap
Mental fog is usually a clearance problem
Your brain runs on oxygen and burns through antioxidants faster than any other organ. When the system falls behind, focus is the first thing to go.
of the body's oxygen is consumed by the brain — despite being roughly 2% of body weight, it's the most oxidatively stressed organ you have.
of the world's population breathes air exceeding WHO pollutant guideline limits.
WHO, 2022Why this formula
Clear the load. Then steady what's left.
Two actives doing two different jobs, in the same capsule.
Glutathione is the antioxidant your cells use to clear oxidative load, and it's made internally — the limiting step is cysteine, the one amino acid your body tends to run short of. Taking glutathione directly doesn't work; most of it is broken apart in digestion. N-acetyl-L-cysteine is the stable, absorbable form of cysteine, which is why it's the form used in the research. That's the clearing half.
L-theanine is the steadying half. It may help promote a settled, alert state without sedation — the difference between quiet focus and wired focus. Neither ingredient does the other's job, which is the reason they're in the same capsule instead of two.
What it supports
What one serving covers
The support this formula is built to give.
Mental Clarity
Supports the antioxidant system your brain depends on most, helping clear the load that shows up as fog.
Calm Focus
200 mg of L-theanine helps promote a settled, attentive state — steady, without the wired edge.
Glutathione Support
NAC supplies cysteine, the limiting building block your cells use to produce glutathione — the antioxidant they rely on most.
Easier Breathing
May help support the body's own airway-clearing processes, so breathing feels less effortful.
Antioxidant Defense
Helps the body manage everyday oxidative stress from air quality, exercise, and normal metabolism.
What's inside
The ingredients doing the work
N-Acetyl-L-Cysteine (NAC)
600 mgThe absorbable form of cysteine — the amino acid your cells need to produce glutathione and clear oxidative load.
More on this ingredient
Cysteine is the rate-limiting building block for glutathione, the antioxidant your cells produce and rely on most. Glutathione taken directly is largely broken down in digestion before it can be used; NAC delivers cysteine in a stable form the body can absorb and put to work.
- 600 mg — the amount used in most research on the ingredient
- Supports the body's own glutathione production
- Stimulant-free
L-Theanine
200 mgAn amino acid from tea leaf that may help promote calm, alert focus without sedation.
More on this ingredient
L-theanine supports a settled, attentive state — steady focus rather than wired focus. It has no stimulant action of its own and no crash.
- 200 mg — the standard single-serving amount studied for calm alertness
- Pairs with morning coffee or works alone
- Non-drowsy
How to take it
How to take it
The whole routine, start to finish.
Take one
One capsule with 6–8 oz of water.
MorningSame time daily
Pick a moment you already repeat — coffee, breakfast, first email. Consistency is what makes it work.
DailyAdjust if needed
Increase only if your practitioner advises it and the label allows it.
As directedPro tips
- Take it with water, not juice — plain water is fine.
- Morning suits the clarity side; afternoon suits the theanine.
- Up to 3 capsules daily if your practitioner advises it.
- Food is optional, but a small snack helps if you're sensitive.
- Consistency beats dose — daily at 1 outperforms occasional at 3.
- Store at room temperature, away from direct sun.

How everything here works
You are what you absorb
You can take the best formula in the world and still get very little from it. Absorption is the part nobody talks about, because the ingredient that solves it costs money.
Every product we make is built around getting nutrients into you rather than just into the tub — enzymes where they help, cold processing that doesn't cook nutrients off, and forms chosen for uptake over shelf price.
Where we started
Recommended in practice, not in ads
BioPharma Scientific formulas were developed for and distributed through doctors, chiropractors and naturopaths for years before anything was sold direct.
Many still stock them today. That channel is why the formulas are built around absorption instead of shelf price.

Questions

Your brain consumes a disproportionate share of the body's oxygen, which means it generates and has to clear a lot of oxidative byproduct. NAC supports glutathione production, the system doing that clearing. L-theanine works on the other side — helping promote a calm, alert state rather than a scattered one.
Glutathione is produced inside your cells, and cysteine is the ingredient that limits how much you make. Taken directly, glutathione is largely broken down in digestion before it can be used. NAC delivers cysteine in a stable form your body can absorb and put to work.
No. L-theanine isn't a sedative — it helps promote a calm, alert state rather than a sleepy one. Most people take this capsule in the morning with no effect on energy.
No. There's no caffeine or stimulant of any kind. L-theanine is often paired with caffeine to smooth it out, but on its own it supports focus without the ramp-up or the crash.
The label allows up to 3 capsules (1,800 mg NAC) per day. Start at one and stay there unless your practitioner recommends otherwise.
Yes. It's a two-ingredient formula with no overlap against our greens, protein, or omega products. Many customers pair it with NanoGreens in the morning.
