Should I take potassium?

Our read is that potassium supplementation is well supported, primarily due to the difficulty in achieving the adequate intake of 4700mg/day, which 97% of Americans fail to meet, as noted by Rhonda Patrick. Experts like Paul Saladino and Andrew Huberman suggest that maintaining a proper sodium and potassium balance is crucial for blood pressure, mental clarity, and physical performance.

However, caution is advised for individuals with kidney disease, those on certain medications like ACE inhibitors or diuretics, and anyone considering high-dose supplementation, as excessive potassium can be harmful, potentially causing heart issues, according to Paul Saladino.

To increase potassium intake, Paul Saladino recommends using salt alternatives like 'low salt' (potassium chloride mixed with sodium chloride) and notes that meat is a significant source. Andrew Huberman suggests ingesting water with salt and a potassium tablet for improved mental clarity and work performance. For specific goals, Paul Saladino mentions that potassium citrate may be beneficial for individuals experiencing oxalate clearing or to prevent kidney stone re-accumulation by weakening calcium bonds.

• 01Rhonda Patrick (3x) states that the adequate intake for potassium is 4700mg/day, which is difficult to achieve, leading to 97% of Americans not meeting this requirement.
• 02Paul Saladino (1x) notes that blood pressure is driven by the sodium and potassium balance.
• 03Andrew Huberman (1x) suggests that ingesting water with salt and a potassium tablet can improve mental clarity and the ability to perform physical and mental work.
• 04Paul Saladino (1x) indicates that potassium supplementation may be beneficial, and potassium deficiency can be exacerbated by sodium deficiency due to kidney exchange mechanisms.
• 05Paul Saladino (1x) recommends salt alternatives like 'low salt' (potassium chloride mixed with sodium chloride) for increasing potassium intake.
• 06Paul Saladino (1x) states that meat is a significant source of potassium, which can contribute to achieving the recommended sodium-potassium balance.
• 07Paul Saladino (1x) suggests that potassium citrate supplementation may be beneficial for individuals experiencing oxalate clearing.
• 08Paul Saladino (1x) notes that citrate forms of minerals can prevent kidney stone re-accumulation by weakening calcium bonds.
• 09Peter Attia (1x) suggests that combining ketones with electrolytes like potassium chloride instead of sodium chloride is a viable option for creating ketone salts without hypertensive effects.
• 10Andrew Huberman (1x) mentions that LMNT electrolyte product contains sodium, potassium, and magnesium malate, which may offset delayed onset muscle soreness and does not cause drowsiness or anxiety.
• 11Paul Saladino (1x) suggests that supplementing with small amounts of potassium and magnesium may help individuals experiencing cramps.

Paul Saladino (1x) warns that individuals with kidney disease or on ACE inhibitors or other angiotensin receptor blockers should be cautious with potassium supplementation as some drugs are potassium-sparing. He also states (1x) that excessive potassium supplementation can be harmful, potentially causing palpitations and arrhythmia, and is regulated by the FDA. High-dose potassium supplementation should only be done after consulting a doctor due to potential dangers, according to Paul Saladino (1x). He also advises (1x) that individuals with high blood pressure taking diuretics like torsemide and potassium supplements should consult their doctor. Paul Saladino (1x) notes that individuals who are normotensive with normal serum sodium, serum potassium, and red blood cell potassium levels likely do not need to supplement potassium.

The verdict would change if new information emerged indicating that the adequate intake for potassium is easily met by the general population, or if further research demonstrated significant widespread harm from moderate potassium supplementation in healthy individuals. Additionally, if the mechanisms by which potassium influences blood pressure and other health markers were disproven, or if the efficacy of potassium in preventing kidney stones or muscle soreness was refuted by expert consensus, the verdict would be re-evaluated.
