BioStacksHow Iron supports skin
When it comes to skin, Iron is one of the most supporting nutrients to consider. 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. Vitamin C taken alongside iron substantially boosts absorption.
How much iron do you need
Research points to 15–45 mg as the effective range for 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. Lower doses may provide some benefit, but most studies showing clear results used this range.
Which form absorbs best
Avoid ferrous sulfate — common gi side effects. Avoid ferrous fumarate — significant gi side effects. Avoid ferrous gluconate — low elemental iron (12%). The most bioavailable options are iron bisglycinate (ferrochel).
Clinical research
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
