By age 50, most individuals show measurable immunosenescence (declining NK cell function, reduced vaccine response, slower pathogen clearance) alongside iron dysregulation (elevated ferritin, increased NTBI, reduced ferroportin expression). Lactoferrin supplementation addresses both simultaneously — making it one of the most mechanistically targeted supplements for the 50+ demographic.

Can lactoferrin help with frequent infections after 60?

Elevated lactoferrin supplementation (300 mg/day) is a reasonable first-line supplement intervention for immunosenescence-related frequent infections. For persistent infection susceptibility, comprehensive immune evaluation (immunoglobulins, lymphocyte subsets) is also warranted.

Does lactoferrin interact with blood pressure medications common in older adults?

No documented interactions between lactoferrin and common antihypertensive medications (ACE inhibitors, ARBs, beta-blockers, calcium channel blockers). Safe to combine.
