Scientific studies have shown that lactoferrin supports the balance of gut microbiota and helps limit the growth of unwanted bacteria in the digestive tract. Research also indicates it may aid intestinal lining regeneration and help relieve issues such as bloating, constipation, or diarrhea – including in individuals with SIBO or IBS⁽²⁾.

Scientific research shows that lactoferrin supports the body’s natural defense mechanisms by helping regulate and maintain a balanced immune response. Studies indicate it may reduce conditions that favor the growth of viruses, bacteria, fungi, and parasites^(1,5). One of its key actions is binding iron – a mineral essential for the growth of many microorganisms – thereby limiting its availability to pathogens⁽⁶⁾.

Scientific studies have shown that lactoferrin may improve iron metabolism^(3,8). It binds free iron ions in the digestive tract, facilitating their absorption and supporting the body’s natural iron balance. Clinical trials have found it can be as effective as ferrous sulfate in improving iron levels in adult women, while being better tolerated by the digestive system⁽⁴⁾ – which is particularly important in times of increased demand or in cases of iron imbalance.

Clinical trials have shown that lactoferrin may have a beneficial effect on skin condition in people with acne. In a randomized study, 12 weeks of lactoferrin supplementation reduced sebum production, decreased the number of inflammatory lesions, and improved overall skin appearance⁽⁷⁾.

Scientific research suggests it may support nervous system health – particularly in the context of aging, cognitive function, and neurodegenerative diseases. Its immunomodulatory, anti-inflammatory properties and ability to bind iron may play a role in preventing or slowing neurodegenerative processes such as Alzheimer’s disease^(9,10).
