Potassimax.
Brain fog, mid-afternoon fade, the name on the tip of your tongue — these are signals from cells running short on a mineral nearly all of us under-consume. Potassimax is the doctor-formulated potassium supplement built to bridge that gap.
You're sharp. You're capable. So why does your brain feel one step behind?
Brain fog rarely announces itself — it shows up as small frustrations that quietly stack up. These are the everyday signals that often point back to one quiet shortfall: not enough potassium. Potassimax is built specifically to bridge that gap.
At work
You re-read the same paragraph three times. The name of a colleague vanishes mid-sentence. By mid-afternoon, simple tasks feel like wading through wet sand.
At home
You walk into a room and forget why. Conversations drift. The mental energy you used to spend on the people you love gets eaten up just getting through the day.
In your energy
It's not sleepiness exactly — it's a flatness. A dimmer switch on your clarity that no amount of coffee seems to turn back up.

Potassium and your brain
Potassimax is built on a simple premise: the brain is an electrical organ, potassium is one of its key electrolytes, and most of us don't get enough. Here's the research that shaped the formula.
Powering neuron-to-neuron communication
Potassium helps maintain the electrical gradient that lets neurons fire and reset. This signaling is fundamental to how the brain processes information — which is why electrolyte balance is considered important for normal cognitive function.
Reviewed in electrolyte & cognitive health literature. NIH ODS ↗Higher intake, better cognitive scores
In large observational studies, older adults with higher dietary potassium intake tended to score better on cognitive tests than those with the lowest intake. These findings show an association — not proof of cause — but they're consistent across several populations.
NHANES cross-sectional analysis, 2025. ScienceDirect ↗A pathway that touches the brain
Randomized trials show potassium can help support healthy blood pressure already in the normal range, and healthy blood pressure is closely tied to long-term brain health. It's one of the better-understood ways the mineral and the mind connect
AHA & clinical trial reviews. Circulation ↗The science is promising — and still developing
What's well established is that potassium is essential, most people don't get enough, and adequate intake supports the cellular and cardiovascular systems your brain relies on. That's the gap Potassimax is built to help close.
More than mental clarity
Inadequate potassium intake has been associated with a range of age-related health concerns in research.*

WHAT MAKES POTASSIMAX DIFFERENT
Not just more potassium — a smarter way to take it.
Most potassium supplements give you a single form in a small token dose. Potassimax was engineered around how potassium actually behaves in the body.
Four bioavailable forms of potassium
Single-form potassium supplements ask the body to absorb one molecule, one way. Potassimax delivers potassium across four complementary, well-studied forms — each absorbed and used a little differently by the body, so more of what you take gets where it needs to go.
Citrate
well-studied, well-tolerated
Gluconate
gentle on the stomach
Bicarbonate
alkalizing form
Chloride
classic electrolyte form
pH 8.0 alkalizing formulation
Most diets skew acid-forming. Potassimax is formulated at pH 8.0 to support your body's normal pH balance and electrolyte function — part of the cellular hydration story behind feeling clear and steady.*
Physician-formulated
Developed by Dave Clayton, MD — a board-certified physician, translational researcher, and health educator. Not a marketing claim: the formulation choices are anchored in clinical thinking.
Made in the USA, GMP-certified facility
Manufactured in the United States in a GMP-certified facility — the quality standard that governs how dietary supplements are produced, tested, and documented.
Clean ingredient list
No fillers, gluten free, no artificial colors. Lightly flavored with coconut and vanilla in the powder formats.
