**Iron** at 25mg per capsule, delivered in a gentle, well-absorbed bisglycinate form — landing in the 15–45mg range clinical work uses to maintain levels and correct deficiency. This bisglycinate chelate (Ferrochel) absorbs far more readily than standard iron salts and is much easier on your gut, with far less of the constipation and nausea that make iron pills miserable.
To get the most from it, take the capsule with a meal plus a source of vitamin C, and keep it away from coffee, tea, and calcium, which all blunt absorption.
One caveat matters more than the dose: iron is the one mineral you shouldn't take just in case. Only supplement if you're genuinely low — menstruating women, pregnancy, or a diagnosed deficiency — because excess iron builds up and turns harmful. And since iron is a leading cause of poisoning in young children, keep it well out of their reach.
