Insulin resistance is driven significantly by adipose tissue inflammation — SASP from visceral fat senescent cells and M1 macrophage infiltration reduce insulin signaling. Lactoferrin's NF-κB inhibition reduces adipose tissue IL-6 and TNF-α production, while its microbiome bifidogenic effect reduces metabolic endotoxemia — both mechanistically relevant for improving insulin sensitivity.

Can lactoferrin replace metformin for blood sugar control?

No. Metformin has robust evidence for blood glucose reduction and cardiovascular protection in type 2 diabetes. Lactoferrin is a complementary supplement with modest metabolic benefits. Do not replace prescribed medications.

How long does lactoferrin take to improve blood sugar markers?

The 12-week metabolic syndrome study showed significant changes at 12 weeks. Fasting glucose may improve faster (4–6 weeks) than HbA1c (which reflects 3-month average blood glucose).
