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.

Natural Support for Stage 1 and Stage 2 Hypertension

Understanding your diagnosis is the first step. Discover how addressing foundational mineral deficiencies can support your cardiovascular health regardless of your current stage.

Decoding Your Diagnosis

Hearing a doctor classify your blood pressure as “Stage 1” or “Stage 2” hypertension can be an intimidating experience. It moves the issue from a vague concern to a clinical diagnosis. Stage 1 (typically readings between 130-139 systolic or 80-89 diastolic) is often the tipping point where doctors begin strongly recommending lifestyle changes. Stage 2 (140/90 or higher) is usually when prescription pads come out.

However, these stages are not just numbers; they represent the degree of tension and resistance within your cardiovascular system. Whether you are in Stage 1 and trying to reverse course before medication is mandated, or in Stage 2 and looking for comprehensive natural support to complement your care, the underlying physiological needs of your body remain the same.

Regardless of your stage, are you addressing the fundamental mineral depletion that is causing your arteries to stiffen and constrict?

The Progression of Vascular Tension

Hypertension progresses when the body’s natural regulatory mechanisms begin to fail. This failure is rarely spontaneous; it is usually the result of long-term nutritional deficiencies, specifically the severe imbalance between sodium and potassium, combined with a lack of the structural minerals needed to keep blood vessels flexible.

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.

In Stage 1, the vessels are beginning to lose their elasticity and the cellular pumps are struggling to maintain fluid balance. By Stage 2, the arterial walls have often become rigid and inflamed, forcing the heart to pump with significantly more force just to circulate blood.

How Tarsul Supports Cardiovascular Function

Tarsul is formulated to provide the exact foundational minerals your cardiovascular system requires to regulate itself, addressing the root causes of vascular tension at any stage:

  1. Potassium for Cellular Regulation: Tarsul provides highly bioavailable Potassium Bitartrate. Potassium is essential for reactivating the sodium-potassium pumps in your cells, which allows the smooth muscle lining of your blood vessels to relax. This natural vasodilation is critical for reducing the resistance that defines both Stage 1 and Stage 2 hypertension.
  2. Sulfur for Arterial Flexibility: The Organic MSM Sulfur in Tarsul provides the building blocks for collagen and elastin. As hypertension progresses, arteries become stiff and rigid. Sulfur helps restore and maintain the youthful elasticity of your blood vessels, allowing them to expand and contract naturally with each heartbeat.

A Proactive Approach to Heart Health

A diagnosis of Stage 1 or Stage 2 hypertension is a clear signal that your cardiovascular system requires immediate, foundational support. While medications can artificially force the numbers down, they do not repair the stiffening arteries or correct the mineral imbalances driving the condition.

Tarsul 60-capsule, 600 gram and 150 gram bottles, the sizes referred to in this natural support for stage 1 and stage 2 hyper
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 integrating Tarsul into your daily routine, you are taking a proactive, root-cause approach. You are providing your body with the potassium it needs to balance sodium and relax vessels, and the sulfur it needs to maintain arterial flexibility and reduce inflammation.

Take Action for Your Cardiovascular Health

Don’t just monitor the numbers. Support your body’s ability to naturally regulate blood pressure with essential mineral nutrition.
