Why I Built CoreSalt™. Notes on a clean electrolyte.

The most ordinary clinical moment in my practice is the one I built CoreSalt™ around. A patient — usually one with hypermobility, POTS, or a job that puts them in the heat for hours — hands me back a half-finished bottle of electrolyte powder. They have tried. The taste, the grit, the artificial sweetness, the bright color of the water. They couldn’t get there. And they quietly stopped.

You cannot supplement what you will not take. That sentence has done more clinical damage in my office than I think most physicians realize. It is the gap between the protocol I write and the one the patient lives.

What was wrong with the bottle.

Most electrolyte products are designed to be mixed into water. That works for the patient with a neutral palate and a high tolerance for sweetness. It does not work for several of the populations I see every week.

Hypermobile and EDS patients often have layered sensory sensitivities — foods, smells, textures — that the rest of the medical world tends to under-weight. Mast cell patients react to the additives in many sports drinks before they react to the minerals. Clean eaters who have spent years removing artificial sweeteners from their diet are not going to drink an electrolyte powder that tastes like a candy aisle. And the athletes — the ones I see who are losing significant sodium in training — have usually figured out that no commercial drink is replacing what they sweat out, and that the alternative is salt tabs that taste like salt tabs.

The clinical consequence is uniform: the patient stops taking it. And then the patient is undertreated. Lightheadedness, cramping, brain fog, exercise intolerance, fatigue that doesn’t match their sleep or training — symptoms that are often, at the root, a mineral problem — persist because the supplement on the shelf is unusable to them.

What I wanted on the shelf.

I wanted what I have always wanted on my own shelf. Clean. Well-dosed. Manufactured to a real third-party standard. Taste-free. Available through the clinician who was going to follow up on it.

Specifically, the brief I wrote for myself was this:

• No artificial sweeteners or colors. The same patients who can’t tolerate salty drinks usually can’t tolerate the sweeteners either.
• A real dose of the core three. Sodium, magnesium, and potassium — in amounts that move the needle, not in trace quantities.
• A capsule, not a powder. No mixing, no flavor, no aftertaste, no negotiation with the palate.
• A small set of intentional partners. Tyrosine for focus under stress. Taurine for fluid balance and recovery. Ginger for stomach comfort and the body’s normal inflammation response.
• Manufactured to a recognized standard. No mystery facility, no proprietary blends, no inability to answer a patient’s questions about what they are actually taking.
• Available through the clinic. So that the formulation, the dosing, and the clinical context arrive together — not as a one-way Amazon transaction.

CoreSalt™ is the formulation that came out of that brief. The capsule is small enough to take with water, food, or whatever else you already drink in a day. The dosing is determined in clinic according to your diet, your training, your climate, and your physiology — not by a sticker on a tub.

The core three. And three partners.

The name is intentional. Sodium, magnesium, and potassium are the core electrolytes. They are the minerals your body cannot manufacture and cannot function without. They are responsible for the core pressures your physiology runs on — blood pressure, vascular tone, intracellular fluid balance, the osmotic gradients that move water through every cell. When the core is off, everything that depends on it follows: energy, cognition, cramping, mood, recovery.

The three partners are not filler. Tyrosine is the amino-acid precursor to dopamine and norepinephrine, and the literature on its support of cognitive performance under stress and fatigue is genuinely robust. Taurine is a clinical favorite in athletic and recovery protocols and participates directly in fluid balance and cardiovascular function. Ginger is included for the most ordinary reason in clinical pharmacology: the capsule should sit easily on the stomach, and ginger helps make that the case.

For the patient who wants the published literature behind each ingredient, the full citation list lives on the CoreSalt™ overview page.

The name. On purpose.

I chose the name CoreSalt™ deliberately, on two axes at once.

The first axis is scientific. Sodium, magnesium, and potassium are the core electrolytes — the minerals your body cannot manufacture and cannot function without. They are responsible for the core pressures your physiology runs on: blood pressure, vascular tone, intracellular fluid balance, the osmotic gradients that move water through every cell of your body. Salt is the most clinically honest word for what we are replacing. Core is what we are replacing it for.

The second axis is phonetic. My last name — Courseault, pronounced core-so — sits between core and salt. The alignment is convenient. It lets the name carry the science and a small reminder of where the formulation came from, which felt appropriate for something that lives on our clinic shelf and not in a retail aisle.

Where it’s made.

CoreSalt™ is manufactured by VitaminLab in Canada — a clinician-grade custom supplement manufacturer that produces in a facility certified by NSF International, the independent public-health organization whose standards govern supplement manufacturing in North America. That certification means the facility has been audited for ingredient identity, label accuracy, contaminant testing, and Good Manufacturing Practices. We chose this standard because the patient who picks up a bottle from my clinic deserves to know exactly what is — and is not — in the capsule.

Where to find it.

For now, CoreSalt™ is available exclusively through our New Orleans clinic. It is not yet sold online or in retail. That decision is deliberate. I wanted to launch it the way I approach everything else at FIT — with a real clinical conversation, a real dosing discussion, and a real clinician on the other side of the bottle. Broader availability may follow. For now, it lives with us.

If you would like to learn more, the full overview — ingredients, dosing context, who it’s for, FAQ, and references — lives on the CoreSalt™ page. Or simply reach out: my team will walk you through it, and if it makes sense for your situation, we will add it to your next visit.

One last thing. The point of CoreSalt™ is not to be a louder marketing claim. It is to be the boring, reliable, well-made thing the patient actually takes — the foundation the rest of the protocol can stand on. Get the core right, and the rest follows.
