Iron 65 mg offers a low-cost way to supplement iron, with fatigue and hair benefits most relevant when iron stores are low.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality40

Iron is identified as ferrous sulfate, making the ingredient form clear. Its absorption and quality cannot be judged confidently from the available detail.

Ingredient Transparency100

The iron amount is stated, making the serving quantity easy to check. The named form also supports a more precise comparison with other iron supplements.

Value For Money100

The serving cost is low in the relevant iron comparison. Good value does not establish whether the amount suits an individual’s iron needs.

Customer Satisfaction92

Customer ratings are favorable across a very large number of reviews. The extensive feedback supports a broad picture of satisfaction without establishing benefits for people with adequate iron.

Product Focus73

Iron may help fatigue and hair shedding when iron stores are low, but extra benefit with adequate iron is not established. The serving exceeds the comparison range without establishing additional benefit or suitability at that amount.
