Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Lactoferrin 100% by Symbiotics
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
Lactoferrin 100% contains one active ingredient: bovine lactoferrin, a protein found naturally in milk and other body fluids. The capsule itself is made with gelatin as an inactive ingredient.
Does it work?
Moderate evidence
The evidence for lactoferrin is mixed. It's rated possibly effective for sepsis and pregnancy-related iron deficiency.
However, it's rated likely ineffective for reducing fetal and premature infant mortality and for preventing necrotizing enterocolitis (a serious gut condition in premature infants). The data we have doesn't show it works reliably for those uses.
How safe is it?
Well-documented data
Lactoferrin is generally well tolerated at typical doses. The most common side effects are gastrointestinal — diarrhea, constipation, nausea, and stomach discomfort — though these are less frequent than with other iron supplements.
At higher doses of 7.2 grams daily, you're more likely to experience constipation, diarrhea, fatigue, chills, or loss of appetite. Long-term safety data are limited, so we don't have much information on how safe it is beyond the short term.
In pregnancy, safety isn't fully established, so use only under medical supervision. Lactoferrin occurs naturally in breast milk, but the safety of taking supplements while breastfeeding hasn't been well studied.
Talk with your doctor or pharmacist before using this product if you're pregnant or breastfeeding.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we checked. Before you start, run your specific medications through the checker on this page or confirm with your doctor or pharmacist that it's okay to combine with anything you're taking.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.
Lactoferrin 100% is generally well tolerated at standard doses and has no known medication interactions. If you're considering it for sepsis or pregnancy-related iron deficiency — the uses with the strongest evidence — talk it over with your doctor or pharmacist first, especially if you're pregnant or breastfeeding, since safety data in those situations are incomplete.

IMMUNE SUPPORT*
Lactoferrin helps coordinate the body's immune response through several mechanisms of action. Its iron-binding property robs fuel needed by cells that are not part of the body while delivering iron to body cells in need. It enhances oxygenation of tissues while supporting white blood cell activity. Lactoferrin also acts as an antioxidant to prevent free radical formation.
Lactoferrin promotes intestinal health by scavenging iron and balancing healthy flora in the GI tract. By modulating healthy levels of iron in the body, Lactoferrin plays a key role in maintaining overall health.
Symbiotics 100% Lactoferrin is freeze dried to preserve maximum bioactivity. Extra processing enhances its protein structure to increase effectiveness.
