Let’s talk about a crucial element of immune system defense: mucus. The optimal function of the gastrointestinal mucus system2 is integral to gut health and immunity, and omega-3s play a key role in helping promote mucus (aka mucosal) integrity.*
These healthy polyunsaturated fatty acids help protect intestinal cells, support intestinal mucosal thickness, and promote proper barrier function of the intestinal mucosa, all of which are vital for immune function in the gut.*
In a 2019 preclinical animal study published in Food & Function, marine omega-3s EPA and DHA, specifically, were found to aid intestinal barrier function and integrity.*
