I use potassium chloride and I switched from magnesium citrate to magnesium glycinate to avoid "loose stools" caused by the former. Also D3, K2, C, B12, zinc, nattokinase, L-lysine, N Acetyl-L-Cystein, turmeric & black pepper and sea salt, combined with a diet of healthy meat, fish, eggs, lettuce, vinegar and herbs. No refined carbs.

The magnesium prevented migraines, muscle-cramps, leg muscle "ripples" and "restless legs". The potassium cured tachycardia and arrhythmia. The rest of the stuff boosts the immune system. I take methylene blue occasionally. Also Hydroxychloroquine.
