Minerals
Iron
In plain language
An essential mineral. Only actually helps if you are deficient - won't boost energy in someone with normal iron levels.
Is it an approved medication?
No — not an approved medication
No - sold as a food/OTC supplement, not a prescription medication in its general form
How strong is the evidence?
Strong, but only if you are genuinely deficient (best confirmed with a blood test)
The main thing to know
Can cause constipation; don't take unless you know you are low, since excess iron isn't harmless.

Essential component of hemoglobin and myoglobin; required for oxygen transport and cellular respiration.
Potential benefits
- Correction of iron-deficiency anemia
- Restoration of energy levels and cognitive function in deficient individuals
