@yerrag - Potassium bicarbonate powder may be the answer. Home wine makers use it to reduce acid in their ferments.

Dr. Peter Rogers explains some interesting things about the role of potassium in the body.

I sampled the kindle version. It is indeed worth buying and learning from. While it may be somewhat flawed in its ideas on pumps, it still has a lot of empirical data to back up its claims on the K/Na relationship.
It may just be the answer (or if not a key piece to solving the puzzle) to my 2 decade long quest to lower my blood pressure naturally.
I am reminded of Dr. William Kelley, a dentist who invented the metabolic typing diet, which for many years before discovering Peat I relied to improve my metabolism, with success. He relied on empirical evidence but his basis was not as solid as Peat's, as he explained that people take to food differently depending on their metabolic type, and that the metabolic is largely dependent on the parasympathetic and symphatetic responses which vary according to metabolic types. I held on to these ideas until I encountered Ray Peat's ideas and found Peats's ideas more coherent while still finding more connecting dots in Peat's ideas than those of William Kelley's. Kelley's is very empirically based, and Ray Peat goes further by explaining the biochemical connection to what basically couldn't explain beyond empiricism.
I liken Rogers using pumps to explain away his observations to Kelley's use of parasympathetic/sympathetic activity to explain his take on metabolism. Both may need more discovery which the passage of time and effort by real scientific approaches eventually bridges, and for people like Ray Peat to connect and put into a more coherent whole of understanding.
Following is Peat's persona in the Delphi persona explaining potassium sufficiency as helpful in lowering blood pressure:
Increasing your potassium intake to meet or exceed the RDA of 4,700 mg could indeed have a significant impact on lowering your blood pressure, Michael, especially when combined with other pro-metabolic lifestyle changes. Potassium plays a central role in regulating blood pressure by balancing sodium levels, relaxing blood vessels, and supporting kidney function. Let’s explore how this works and what you can do.
Potassium and Blood Pressure
Sodium-Potassium Balance: Potassium works in opposition to sodium to regulate fluid balance and blood pressure. While sodium is essential for maintaining blood volume and metabolic function, an imbalance—too much sodium relative to potassium—can contribute to hypertension. Increasing potassium intake helps the kidneys excrete excess sodium, reducing blood pressure [1][6].
Vascular Relaxation: Potassium directly relaxes the walls of blood vessels, improving their flexibility (compliance) and reducing vascular stiffness, which is often a factor in hypertension, especially with aging [8].
Kidney Function: Potassium supports healthy kidney function by reducing the activation of the renin-angiotensin-aldosterone system (RAAS), a hormonal system that can drive hypertension when overactive. Sodium restriction, ironically, can worsen this system, while adequate potassium helps to regulate it [7][8].
Lifestyle Changes to Support Blood Pressure Reduction
Increase Potassium-Rich Foods: Focus on potassium-dense, metabolically supportive foods:
Fruits: Bananas, papaya, cantaloupe, and oranges are excellent sources.
Dairy: Milk and cheese provide potassium while also supplying calcium, which is critical for blood pressure regulation.
Coconut Water: A great source of potassium, though moderation is key to avoid excess phosphate.
Cooked Greens: Spinach, kale, or chard are rich in potassium and magnesium, both of which support vascular health.
Maintain Adequate Sodium: Contrary to conventional advice, restricting sodium can worsen blood pressure by activating stress systems like RAAS and increasing vascular stiffness. Adequate sodium intake, paired with sufficient potassium, helps maintain blood volume and metabolic rate while preventing the maladaptive stress responses associated with low sodium [6][7].
Magnesium and Calcium: Magnesium acts synergistically with potassium to relax blood vessels and prevent spasms, while calcium helps regulate vascular tone and counteracts the effects of phosphate and parathyroid hormone (PTH) on blood pressure [1][4]. A diet rich in milk, cheese, and cooked greens can provide these minerals in balance.
Thyroid Support: Hypothyroidism can contribute to hypertension by increasing vascular resistance and reducing metabolic rate. Supporting thyroid function with adequate protein, carbohydrates, and thyroid-friendly nutrients like vitamin A and selenium can help normalize blood pressure over time [5].
Reduce Stress Hormones: Chronic stress elevates cortisol and adrenaline, which can drive hypertension. Ensuring stable blood sugar with frequent meals that include protein, carbohydrates, and fat can help reduce stress hormone production. Avoiding excessive caffeine and ensuring adequate salt intake are also important.
Potential Impact on Blood Pressure
The degree to which increasing potassium and making these lifestyle changes will lower your blood pressure depends on the underlying causes of your hypertension. If your high blood pressure is primarily driven by factors like low potassium, high stress hormones, or thyroid dysfunction, these changes could lead to significant improvements. In some cases, dietary and lifestyle adjustments alone can normalize blood pressure without the need for medication.
Practical Steps
Track your potassium intake to ensure you’re consistently meeting or exceeding the RDA of 4,700 mg. Apps or food diaries can help with this.
Pair potassium-rich foods with adequate sodium and calcium to maintain mineral balance.
Monitor your blood pressure regularly to observe how these changes affect it over time.
