Dad & Me Kids Milk Powder With Lactoferrin

Lactoferrin's one where the answer turns more on your situation than on the ingredient, so here's the triage our naturopaths run before anyone buys it.

A good fit if

• Iron tablets have left you constipated or queasy and you want to see what else has been trialled
• You're comparing lactoferrin with colostrum and want the one protein rather than the whole fraction
• You're fine with dairy and you're looking for general immune or gut support
• You'd rather have the evidence and its limits than a marketing line

Check with us first if

• Prescribed iron is already on your list, because lactoferrin binds iron and the measured fraction absorbed went down, not up.
• Pregnancy, or planning one. It's been given in pregnancy trials in women at high risk of preterm birth, and that isn't the same as an established safety position for general use.
• Breastfeeding, where we found no trial in lactating women at all.
• It's for a child. The children's trials were medically supervised, in specific conditions, at 100 mg a day.
• You're being treated for H. pylori, where lactoferrin has only been studied as an addition to prescribed antibiotics.
• Anaemia has been diagnosed, because that one gets managed with blood tests by whoever diagnosed it.
• You're thinking about gram-scale doses. At 3.4 g a day, antibodies to the cow protein rose around threefold, and what that means clinically isn't known.

• Bovine lactoferrin (Schedule 1 item 941). Best known for: The only lactoferrin permitted as an active in an Australian listed medicine, and the one the trials used. Absorption: Degraded by the physical and chemical stresses of digestion; lactoferricin is undetectable in gut contents. Typical use: Permitted listed with no specific requirements, no warning statement, no dose cap and no route restriction.
• Enteric-coated bovine lactoferrin. Best known for: The same protein with a coating meant to carry it past stomach acid intact. Absorption: Stabilisation technologies are reviewed as a response to that degradation, but none is shown to work better clinically. Typical use: The only adult tolerability trial in our register used an enteric-coated 200 mg dose. No head-to-head against uncoated exists, so no superiority claim can be made.
• Apolactoferrin versus holo-lactoferrin. Best known for: Iron saturation state, which is the distinction product pages lean on hardest. Absorption: Nothing in our register measures one against the other. Typical use: Neither name appears in Schedule 1 and no clinical comparison exists, so we don't write one.
• Lactoferricin. Best known for: The fragment pepsin releases from lactoferrin, described as its functional domain, and used in infant formula. Absorption: Undetectable in gut contents. Typical use: Not in Schedule 1, so it can't be the active in an Australian listed medicine.
• Recombinant human lactoferrin. Best known for: A human-sequence protein brewed in yeast rather than purified from milk, trialled at 0.34 and 3.4 g a day. Absorption: Not compared with the bovine protein on absorption in our register. Typical use: Safety and immunogenicity data only so far, and not in Schedule 1, so it can't be a listed-medicine active here. Don't treat it as the same substance.
• Bovine colostrum (Schedule 1 item 940). Best known for: Whole colostrum, which contains lactoferrin alongside many other components. Absorption: A mixture rather than an isolate, so it can't be compared like for like. Typical use: Listed separately and carries a mandatory under-12-months warning that lactoferrin on its own doesn't.

Reference values. There isn't one. Lactoferrin isn't an essential nutrient, so the NHMRC sets no RDI, no Adequate Intake and no Upper Level for it, at any age.

Typical supplemental range. We won't quote a standard Australian capsule strength, because we haven't checked one against a current pack. Read the label in your hand. For scale, the adult trials in our register used 200 mg a day: 200 mg for the inflammation-marker work, and 200 mg enteric-coated in the only adult tolerability trial. The children's iron trials used 100 mg a day for three to four months, all of it medically supervised.

Upper level. Schedule 1 sets no daily dose cap on bovine lactoferrin, and there's no NRV Upper Level either. The highest dose with published safety data in healthy adults in our register is 3.4 g a day for 28 days, which is far above what's sold on a shelf.

Worth knowing. Nobody has tested it with food against on an empty stomach, so there's no evidence-based instruction on timing, and anyone who gives you one is guessing. Your needs depend on your age, diet and health circumstances. Talk to one of our naturopaths.

Food first, where the diet allows it.

• Cow's milk and skim milk: naturally present, and the industrial starting material. No verified milligrams per glass exists, so we won't print one
• Cheese whey: the other industrial source, and where supplement-grade lactoferrin is purified from
• Human breast milk: described as a major iron-binding protein in human milk; an amount per feed isn't established in our register
• Bovine colostrum: contains lactoferrin among many other components, and is sold as an ingredient in its own right
• Infant formula products: fortified with bovine lactoferrin under an express food-law permission in Standard 2.9.1

This list is the part of the page we will not shorten. If any of it applies to you, talk to one of our naturopaths or your doctor before starting.

• Cow's milk allergy. Bovine lactoferrin is purified from cheese whey or skim milk and is a dairy allergen. No lactoferrin product may be described as dairy free or suitable for a milk allergy.
• Vegans and vegetarians. It's an animal-derived milk protein. A suitability exclusion rather than a safety one.
• Pregnancy. Given in trials in women at high risk of preterm birth, whose authors call for adequately powered trials. Not an established safety position for general supplementation. Refer to a health professional.
• Breastfeeding. No trial in lactating women is in our register. Unknown, so refer.
• Prescribed oral iron. Lactoferrin binds iron and fractional absorption measured lower, not higher, in pooled trials and in an isotope study. Don't assume the two add up; raise it with a pharmacist.
• H. pylori antibiotic therapy. Studied only as an adjunct to prescribed treatment, open-label and single-centre. Never a substitute.
• Children. Trials at 100 mg a day reported no adverse effects, but they were medically supervised studies in specific conditions.
• Premature and very low birthweight babies. Hospital territory, not retail. In one trial of 2,203 infants there were 16 serious adverse events on lactoferrin against 10 on control, two of them assessed as possibly related.
• High doses. No daily cap is recorded in Schedule 1. The highest published adult safety data is 3.4 g a day for 28 days, where anti-lactoferrin antibodies rose about threefold with no adverse events identified.
• If you take prescription medicines, check with your doctor, pharmacist or our naturopaths before starting.
