3 Ways Omega-3s Promote Gut Health, Function & Integrity*
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.*
3 ways omega-3s promote gut health
Here are three of the most impactful ways these unique fats promote gut health:
1. Influence gut microbiota
Our gut microbiota are made up of a diverse, complex community that's affected by a myriad of nutrients and bioactives—including omega-3 fatty acids. It turns out omega-3s play a part in regulating both the diversity and abundance of gut microbiota (specifically, the beneficial bacteria).*
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 review1 published in the International Journal of Molecular Sciences found that the gut microbiota of adults positively changed after taking omega-3 supplements.*
(Another reason to take high-quality fish oil every day, if you aren't already!)
2. Support gut function & immunity
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.*
3. Bolster anti-inflammatory actions
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.
If you are pregnant, breastfeeding, or taking medications, consult with your doctor before starting a supplement routine. It is always optimal to consult with a health care provider when considering what supplements are right for you.
