IgG Protect Ingredients & Drug Interactions
What is this page for?

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 IgG Protect by Ortho Molecular Products
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
IgG Protect contains two active ingredients: Lactoferrin and Immunoglobulin G (IgG), both naturally occurring proteins found in milk and colostrum. Lactoferrin is an iron-binding protein, and IgG is an antibody that plays a role in immune defense.
The product also contains a small amount of inactive ingredients — a vegetable capsule and magnesium stearate — to hold the formula together.
Does it work?
Moderate evidence
The evidence for lactoferrin is mixed and depends on what you're using it for. It's possibly effective for sepsis (a severe blood infection) and pregnancy-related iron deficiency.
However, it's been rated likely ineffective for reducing fetal and premature infant mortality and for preventing necrotizing enterocolitis (a serious intestinal condition in newborns). We hold no effectiveness data on Immunoglobulin G or the overall formula in our current system.
How safe is it?
Well-documented data
Lactoferrin is generally well tolerated at typical doses. At higher doses — around 7.2 grams daily — constipation, diarrhea, loss of appetite, fatigue, and chills have been reported.
Gastrointestinal side effects like these are less common with lactoferrin than with other forms of supplemental iron. Long-term safety data are limited.
In pregnancy, lactoferrin has been studied but safety is not fully established; use only under medical supervision. While lactoferrin occurs naturally in breast milk, the safety of supplements while breastfeeding hasn't been well studied — talk with your doctor or pharmacist before using it.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That said, we could not verify Immunoglobulin G — if you take any medications, use the interaction checker on this page or ask your pharmacist to be certain.
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.
IgG Protect is a milk-based immune support formula. If you're pregnant, breastfeeding, or take regular medications, check with your pharmacist before starting — especially since we haven't checked Immunoglobulin G for drug interactions and long-term safety data on lactoferrin are sparse.
