Laktoferrin 350mg by Allergy Research Group

If your Ferritin (the iron storage marker) stays low despite taking oral iron, lactoferrin is a smart add-on. It’s helpful for menstruating adults with low Hemoglobin, athletes with heavy training loads, and postpartum women rebuilding iron. It also fits people with sensitive digestion who don’t tolerate high-dose iron. If your Ferritin is already high or you have hemochromatosis, skip lactoferrin for iron and talk with your clinician.

Lactoferrin is an iron-binding protein from milk. In the gut it escorts iron to where it’s absorbed, while tying up excess “free” iron that feeds harmful microbes. Human studies suggest it can lower hepcidin (the liver hormone that blocks iron absorption), which is one reason Ferritin and Hemoglobin can rise over 4 to 12 weeks. By limiting iron to pathogens, lactoferrin also helps with microbiome balance and modestly lowers hs-CRP (an inflammation marker) in some responders.

The suggested use is 1 to 3 capsules at night before bed. That timing keeps it away from large calcium-rich meals that compete with iron handling. If you’re repleting iron, pairing lactoferrin with a lower-dose iron supplement earlier in the day often improves tolerance versus pushing iron alone. Recheck Ferritin and Hemoglobin after 8 to 12 weeks, then taper to a maintenance dose once your levels are solid.

Avoid lactoferrin if you have a true cow’s milk protein allergy. It’s typically very low in lactose, but strict dairy-free vegans may still prefer to avoid it. If your Ferritin or Transferrin Saturation (how full your iron carriers are) is high, or you have hemochromatosis or are on iron chelation, do not use it for iron. Pregnancy and nursing: commonly used, but confirm dosing with your OB before starting.
