Before you read on — a word about potassium and prescriptions

Cream of tartar is a concentrated source of potassium. That is the point of it, and for most people it is unremarkable. But potassium is one of the few minerals where more is not automatically better, and a handful of common prescriptions change how your body holds on to it.

Talk to your doctor or pharmacist before adding Tarsul if you take a potassium-sparing diuretic (spironolactone, triamterene, amiloride), an ACE inhibitor (lisinopril, enalapril, ramipril), an ARB (losartan, valsartan, irbesartan), a potassium supplement or salt substitute, or regular NSAIDs — and if you have reduced kidney function or have been told to watch your potassium, ask first. It is a five-minute conversation and worth having.

And please do not stop, reduce, or replace a prescribed medication on your own. Nothing on this page is a reason to change what your doctor put you on. If you want to discuss it, discuss it with them. Fuller detail on serving sizes and precautions is on our dosage and precautions page.

Gut Health and High Blood Pressure: The Hidden Connection

Explore the cutting-edge science linking digestive dysbiosis to cardiovascular tension, and discover how a dual-action mineral approach supports both systems.

The Unexpected Source of Vascular Inflammation

When treating high blood pressure, the focus is almost exclusively on the heart, the kidneys, and the blood vessels. However, emerging cardiovascular research is increasingly pointing to a different origin point for systemic inflammation and hypertension: the gut microbiome.

If you have struggled to manage your blood pressure despite dietary changes and exercise, the missing link may reside in your digestive tract. A compromised gut lining—often driven by a modern diet high in sugar and processed foods—allows toxins and invasive organisms to enter the bloodstream. This triggers a body-wide inflammatory response that directly damages the delicate lining of your blood vessels.

Are you trying to lower your blood pressure while ignoring the chronic digestive inflammation that is driving it up?

The Endothelial Impact

The inner lining of your blood vessels, called the endothelium, is responsible for producing nitric oxide—the molecule that tells your arteries to relax and dilate. When toxins from a leaky or imbalanced gut enter the bloodstream, they cause endothelial dysfunction. The vessels become inflamed, stiff, and unable to produce sufficient nitric oxide, resulting in chronic high blood pressure.

Cream of tartar and MSM sulfur powder, the two ingredients in Tarsul, in the context of blood pressure and circulation — Tarsul is a fine white powder — potassium bitartrate (cream of tartar) combined with MSM sulfur — stirred into water rather than swallowed as a tablet.

To truly support cardiovascular health, you must address this inflammatory cascade at its source.

Tarsul: A Dual-Action Approach

Tarsul was originally formulated with a very specific, aggressive goal in mind: to eradicate the overgrowth of invasive organisms in the gut caused by excess sugar intake. Its ability to support cardiovascular health is a direct result of this powerful digestive cleansing action, combined with essential mineral replenishment.

Addressing Gut Dysbiosis: Organic MSM Sulfur acts as a powerful agent against unwanted gut pathogens. Much like caprylic acid targets excess yeast, the sulfur in Tarsul helps clear out the invasive organisms that drive chronic gut inflammation. By supporting a cleaner digestive environment, Tarsul helps halt the flow of inflammatory toxins into the bloodstream, protecting the vascular lining.
Restoring Vascular Balance: Once the inflammatory burden from the gut is reduced, the cardiovascular system can begin to heal. The Potassium Bitartrate in Tarsul then provides the essential electrolyte needed to reactivate the cellular pumps, allowing the blood vessels to naturally relax and regulate pressure.

Healing from the Inside Out

You cannot separate the health of your heart from the health of your gut. If your digestive system is inflamed and overrun by invasive organisms, your cardiovascular system will bear the brunt of that toxic load.

Tarsul 60-capsule, 600 gram and 150 gram bottles, the sizes referred to in this gut health and high blood pressure connection — Tarsul is sold in a 150 gram bottle, a 600 gram bottle and a 60-capsule bottle. Dosing guidance is on the ingredients page.

By utilizing Tarsul, you are addressing the problem at both ends of the spectrum. You are providing the sulfur needed to support the gut and reduce systemic inflammation, while simultaneously delivering the potassium required to support vascular relaxation. It is a comprehensive, root-cause approach to long-term health.
