What Researchers Say

Peter Attia
Peter Attia Agrees

Dedicated iron episode. Recommends testing ferritin, TIBC, and transferrin saturation before supplementing.

Rhonda Patrick
Rhonda Patrick Nuanced

Warns against excess iron as an aging accelerant via oxidative stress.

Mark Hyman
Mark Hyman Strongly Agrees

Includes iron bisglycinate in his personal daily stack. Flags it as one of the most prevalent deficiencies.

Bryan Johnson
Bryan Johnson Agrees

Actively supplements heme iron for borderline levels.

Detailed Answer

Iron is uniquely dangerous among supplements because both deficiency and overload cause serious harm. Every expert agrees: test before supplementing.

Attia has a dedicated episode covering iron biochemistry. He recommends testing ferritin, TIBC, and transferrin saturation. Patrick specifically warns that excess iron accelerates aging through oxidative stress.

Hyman includes iron bisglycinate in his daily stack and identifies iron as one of the most prevalent deficiencies. Johnson supplements heme iron for borderline levels.

Never take iron supplements without confirming deficiency through blood work. Men and postmenopausal women rarely need supplementation.
