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.

WHY PEOPLE REACH FOR POTASSIMAX

Built around the everyday potassium gap

Daily mineral support*

Closing the gap most adults walk around with, as part of routine nutrition.

Hydration & electrolyte balance*

Potassium is one of the body's primary intracellular electrolytes.

Mental clarity & everyday energy*

Supporting the cellular signaling and hydration systems behind feeling sharp.

Around active days & long ones

Some customers like having it on hand around physical activity and at the end of long days.

*These structure/function statements describe how potassium supports normal cellular and electrolyte function. They have not been evaluated by the FDA. Potassimax is not intended to diagnose, treat, cure, or prevent any disease.

Sound familiar?

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.

What the research actually says

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.

01 — Cellular signaling

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.

02 — Population studies

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.

03 — Blood pressure link

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

Why we're not overpromising

The science is promising — and still developing

We want to be straight with you: not every study agrees. At least one well-designed long-term study found no clear cognitive effect from potassium intake, and there are no clinical trials proving a supplement clears brain fog or boosts memory.

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.

1 You fall short. Like ~97% of adults, your daily potassium likely lands well below the target.

2 You bridge the gap. Potassimax adds a measured, clean dose of potassium to your routine.

3 Your cells stay supplied. Adequate potassium supports the signaling, hydration & blood-pressure systems behind clear thinking.*

Why potassium matters as we age

More than mental clarity

Inadequate potassium intake has been associated with a range of age-related health concerns in research.*

Inadequate intake of potassium linked to heart disease, hypertension, kidney disease, osteoporosis, stroke, and kidney stones.
