Lactoferricin vs Semaglutide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Lactoferricin
Lactoferricin is an antimicrobial peptide derived from lactoferrin, a protein found in milk and other secretions. It has potent antibacterial, antiviral, and antifungal properties.
Full details →Semaglutide
Semaglutide is a GLP-1 receptor agonist that has revolutionized weight management and diabetes treatment. FDA-approved as Ozempic (diabetes), Wegovy (weight loss), and Rybelsus (oral form), it has become one of the most prescribed peptides worldwide.
Full details →Side-by-Side Comparison
| Aspect | Lactoferricin | Semaglutide |
|---|---|---|
| Mechanism | Binds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects. | Mimics glucagon-like peptide-1 (GLP-1) to stimulate insulin secretion, suppress glucagon release, slow gastric emptying, and reduce appetite through hypothalamic signaling. The result is significant reduction in food intake and improved glycemic control. |
| Typical Dosage | Research applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily. | Wegovy (weight loss): Start at 0.25mg weekly, titrate up to 2.4mg weekly over 16-20 weeks. Ozempic (diabetes): 0.25mg to 1mg weekly. Research protocols vary. |
| Administration | Available through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings. | Subcutaneous injection once weekly, typically in abdomen, thigh, or upper arm. Rybelsus is taken orally on empty stomach. Dose titration is essential to minimize GI side effects. |
| Side Effects | Lactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies. | Common: nausea, vomiting, diarrhea, constipation, abdominal pain. These typically decrease over time. May cause injection site reactions. |
