Of the minerals listed (magnesium, iron, phosphorus, and calcium), iron typically has the smallest daily requirement.
For example, the recommended dietary allowance (RDA) for iron varies by age and sex but is generally around 8 mg per day for adult men and 18 mg per day for adult women (due to menstruation). In comparison, the RDAs for magnesium, phosphorus, and calcium are generally higher.
Always check the specific recommendations from health authorities or a healthcare provider for personalized dietary advice.
