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.
Lisinopril, Amlodipine, and Beta Blockers: How They Affect Minerals
If you are experiencing the side effects of standard blood pressure medications, discover how supporting your body’s natural mineral balance offers a different approach to cardiovascular health.

The Reality of Standard Prescriptions
When you are prescribed a medication like Lisinopril (an ACE inhibitor), Amlodipine (a calcium channel blocker), or a beta blocker, the goal is straightforward: force the blood pressure numbers down. These drugs are highly effective at doing exactly what they are designed to do. However, they achieve this by chemically interrupting your body’s natural regulatory systems.
This interruption often comes with a significant cost to your quality of life. The chronic dry cough associated with ACE inhibitors, the swelling in the ankles from calcium channel blockers, and the profound fatigue and sexual dysfunction often linked to beta blockers are not just minor inconveniences—they are signs that your body’s normal functions are being artificially suppressed.
How These Medications Work (And What They Miss)
To understand why a natural approach is necessary, it helps to understand what these drugs are actually doing:

- Lisinopril (ACE Inhibitors): Blocks the production of angiotensin II, a chemical that narrows blood vessels.
- Amlodipine (Calcium Channel Blockers): Prevents calcium from entering the muscle cells of the heart and blood vessels, forcing them to relax.
- Beta Blockers: Blocks the effects of the hormone epinephrine (adrenaline), causing the heart to beat more slowly and with less force.
Notice what is missing? None of these medications address why your body felt the need to constrict those vessels or increase the heart rate in the first place. They do not repair stiff arteries, and they do not correct the severe mineral deficiencies that drive hypertension.
The Tarsul Difference: Restoring the Foundation
If you are looking for a natural alternative to Lisinopril, Amlodipine, or beta blockers, you need a solution that addresses the root cause of vascular tension rather than just masking the symptoms. Tarsul provides a foundational approach through two essential minerals:
- Potassium for Natural Vasodilation: Instead of chemically blocking calcium (like Amlodipine), Tarsul provides highly bioavailable potassium (Cream of Tartar). Potassium is the body’s natural counterbalance to sodium. It reactivates the sodium-potassium pump in your cells, allowing your blood vessels to naturally relax and widen without the need for chemical intervention.
- Sulfur for Structural Integrity: Instead of just blocking the signals that cause constriction (like Lisinopril), Tarsul provides Organic MSM Sulfur to rebuild the structural health of your arteries. Sulfur is crucial for the production of elastin and collagen, the proteins that keep your blood vessels flexible. Stiff arteries force blood pressure up; flexible arteries accommodate blood flow naturally.
A Path Toward Natural Regulation
Transitioning away from reliance on pharmaceuticals requires rebuilding the health of your cardiovascular system. By addressing the critical deficiencies in potassium and sulfur, you are giving your body the tools it needs to regulate blood pressure naturally.

Tarsul supports the health of the endothelial lining, promotes natural vasodilation, and helps restore the flexibility of your blood vessels. It is a comprehensive approach to cardiovascular wellness that focuses on healing rather than suppression.
