Potassium is an essential electrolyte crucial for maintaining fluid balance, nerve signals, and muscle contractions, including heart rhythm. Adequate intake is strongly linked to lower blood pressure, reduced risk of stroke, and improved cardiovascular health, all critical factors for extending healthspan and reducing age-related disease burden. It also plays a role in bone health and kidney stone prevention.

Protocol
- Aim for adequate dietary intake, typically 3,500-4,700 mg/day, from whole foods like fruits, vegetables, and legumes.
- Supplementation may be considered under medical supervision for confirmed deficiency or specific conditions.
Flags
- High doses or supplementation can cause hyperkalemia, especially with impaired kidney function.
- Interacts with ACE inhibitors, ARBs, and potassium-sparing diuretics, increasing hyperkalemia risk.
- Symptoms of hyperkalemia include muscle weakness, fatigue, and potentially life-threatening heart arrhythmias.
- Always consult a physician before supplementing, especially if on medication or with kidney disease.
