Thanks to a cat owner who tripled its sea salt and got rid of its diabetes, it triggered me to up my salt intake to that of a saline IV. That is 1.5 tsp. per quart of water consumed. I confirmed that requirement with an energy test by a chiropractor. That change cut my episodes of AFIB 75% and far less severe. I now have a near normal life & it did not cost me one cent.
Yes sea salt makes all the difference. I grew up with adrenal fatigue which turned into exhaustion/burnout 3.5 years ago. During this phase the adrenals don't produse aldosterone (anti-diuretic hormone) so the kidneys leak salt. As a result the potassium you eat is not absorbed - or very little of it - so that the balance is maintained in the body. When your levels are so low the heart cannot work properly. Until you start salting your water and food your potassium will remain very low. The heart problems - unless there is a physical malformaton or damage - are pure de-hydration.
In the morning drink a glass of water with a little salt in it. Experiment with the dosage. Shouldn't overdo it to start with. Try to eat at least one big green salad a day sprinkled with salt. Avoid in the evenings as you may get very thirsty in the middle of the night. I use Celtic Sea Salt, completely unprocessed and very tasty. Eat bananas too. You should see the difference in a couple of days.
Finally, I cant praise magnesium chloride enough. Magnesium is notoriously difficult to absorb. The absolute best & fastest way to replenish the body is transdermally. It's like balm for the adrenals.
