If Your Gut Health Isn’t Ideal, You May Be Lacking These Nutrients

Omega-3s offer incredible benefits that extend beyond heart and brain health support.* One unexpected perk of consuming omega-3s? Gut health.

It turns out a high-quality probiotic isn’t the only supplement that supports a healthy gut; evidence shows that getting sufficient omega-3s regularly via diet and supplementation bolsters gut function and overall health to promote healthy digestion, detoxification, immunity, and mental well-being.*

A 2021 scientific review titled Associations among Dietary Omega-3 Polyunsaturated Fatty Acids, the Gut Microbiota, and Intestinal Immunity outlines the ways omega-3s can help modulate the gut microbiome and promote gut immunity.* 

Here are three of the most impactful ways these unique fats promotes gut health.

In fact, higher concentrations of omega-3s in the blood are correlated with an elevated abundance of microbiota in the gut—and not just from diet.* A 2017 review published in the International Journal of Molecular Sciences found that the gut microbiota of adults positively changed after taking omega-3 supplements.*

Let’s talk about a crucial element of immune system defense: mucus. The optimal function of the gastrointestinal mucus system 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.* 

Omega-3s have some seriously potent anti-inflammatory properties that help promote gastrointestinal, cardiovascular, neurological, joint, and whole-body health.*

In addition to modulating the production of anti-inflammatory compounds, omega-3s are known to modulate critical immune responses and combat pro-inflammatory pathways in the gut.*

Thanks to their anti-inflammatory and antioxidant actions, omega-3s also help combat oxidative stress in immune and intestinal cells to help support the body’s immune defenses and protect the gut.* Omega-3s truly take the term “healthy fat” to another level!

Given their widespread benefits, it’s pretty obvious that omega-3s are vitally important to gut health and function—but the relationship goes the other way too.* 

Microorganisms in the GI tract are crucial for the biotransformation of fatty acids. In other words, a healthy gut is key for optimal absorption and metabolism of omega-3 fatty acids.

Consider pairing a high-potency, sustainably sourced fish oil supplement (like mbg’s omega-3 potency+) with a targeted, high-quality probiotic (like mbg’s probiotic+) to comprehensively support gut health, bolster intestinal barrier function, and elevate gut microbial abundance and diversity.*
