Quick Answer

Context-dependent. Huberman: 1,600-3,200mg for healthy active adults. Attia: restrict if blood pressure >120/80 - high sodium triggers fructose production. Johnson gives no number on the record. Check your blood pressure first.

What Researchers Say

Andrew Huberman
Andrew Huberman Strongly Agrees

1,600-3,200mg for healthy active adults. Sodium is essential for every nerve impulse.

Peter Attia

High sodium triggers fructose production via polyol pathway. Restrict if hypertensive.

Bryan Johnson

Uses sodium-free salt substitutes. Experienced severe cramps from electrolyte depletion during sauna experiment.

Detailed Answer

Sodium intake depends heavily on blood pressure and activity level. Huberman recommends 1,600-3,200mg for healthy active adults, noting sodium is essential for every nerve impulse. He provides the Galpin equation for exercise: body weight (lbs) / 30 = ounces of fluid every 15-20 minutes.

Attia provides the counterpoint: high sodium triggers endogenous fructose production, contributing to hypertension. He recommends restriction as a first-line intervention if blood pressure is above 120/80.

Johnson's own sodium target is not stated on the record; where he does raise sodium it is to criticise the load in ultra-processed and fast food. Hyman warns that over-drinking plain water without electrolytes dangerously dilutes blood minerals.

Should I supplement electrolytes during fasting?

Yes. Huberman recommends electrolyte supplementation especially during fasting and exercise to maintain neuronal function.
