Lactoferrin

Tier 2 — promising · Iron absorption · Immunity · Gut

A gentle way to improve iron levels without the stomach side effects of standard iron pills. Several RCTs in pregnancy (Paesano 2014, Rezk 2016) found bovine lactoferrin raised haemoglobin and ferritin comparably to ferrous sulphate with significantly fewer GI side effects. Also supports immune function via modulation of gut inflammation. Can be combined with iron supplements. Very well tolerated. Avoid if severely allergic to dairy.

Dose: 100–250 mg/day bovine lactoferrin; can be combined with iron for enhanced absorption
