Autoimmune diseases involve excessive immune activation against self-tissue. Lactoferrin's anti-inflammatory mechanisms (NF-κB inhibition, IL-10 and Treg promotion) potentially reduce pathological immune activity without compromising overall immune surveillance — distinguishing it from immunosuppressive drugs that broadly reduce immune function.

Is lactoferrin safe with autoimmune medications (biologics, DMARDs)?

No documented pharmacokinetic interactions with common biologics (adalimumab, etanercept) or DMARDs (methotrexate, hydroxychloroquine). However, combined immunomodulatory effects should be monitored by your rheumatologist.

Does lactoferrin help with Crohn's disease?

Some case reports and observational data suggest benefit. Lactoferrin's gut barrier support, bifidogenic microbiome promotion, and NF-κB inhibition are all relevant to Crohn's pathophysiology. Controlled human trials are lacking.
