Why Iron for Skin

Iron plays a supporting role in skin. Essential for oxygen transport via hemoglobin and energy production in mitochondria. Iron bisglycinate (Ferrochel) offers 2–4x higher bioavailability than ferrous sulfate with significantly less GI distress—it's the preferred supplemental form.

What dose to look for

Clinical studies typically use 15–45 mg of iron. 15-25 mg for prevention/maintenance, 25-45 mg for deficiency treatment. RDA is 8 mg (men) / 18 mg (premenopausal women). Bisglycinate forms effective at lower doses due to 2-4× bioavailability. Products below this range may not deliver meaningful results.

What form to look for

Avoid ferrous sulfate — common gi side effects. Avoid ferrous fumarate — significant gi side effects. Avoid ferrous gluconate — low elemental iron (12%). Look for iron bisglycinate (ferrochel) for better absorption.

What the research says

Iron has strong clinical evidence for skin benefits. Essential for oxygen transport via hemoglobin; bisglycinate form has 2-4x better absorption than ferrous sulfate Learn more

Clinical research on Iron

MODERATE for skin in deficient populations · 18–65 mg/day (when deficient)

•Iron deficiency causes pallor and poor skin complexion — supplementation restores skin color when ferritin is low
•Required for oxygen transport to skin tissue and collagen hydroxylation via prolyl hydroxylase
