How Supporting Your Gut Health Can Boost Immunity*

More than ever, we are recognizing how the state of our gut and microbiome is connected to our immune system and overall quality of life. The gut lining is one of the body’s most essential defense barriers, and when this barrier is compromised it becomes more permeable. As a result, the immune system – of which 70% is located in the gut – reacts and requires additional support. Therefore, to maintain a healthy immune system, gut and microbiome health are the first things to get on track to help your body’s immune system.*

We know the importance of frequent handwashing, nutritious diets, regular exercise, and plenty of rest to support your immune system. Still, these might not be enough if you lack the nutrients needed for a robust immune system.

When taking proactive steps to protect your immunity, follow these steps to nourish the gut-immune connection:

1. Identify and remove triggers of gut inflammation

• Processed food and foods high in sugar have been shown to compromise the gut lining and impact the balance of the gut microbiome, contributing to a “leaky” gut. [1] his increase in permeability leads to systemic inflammation, putting a strain on the immune system. Consider giving your gut a break by eliminating highly processed food and those lacking healthy fibre. Cutting out sugar, gluten, dairy, corn, and soy for 4–6 weeks is an ideal amount of time to clear these common triggers of gut inflammation and help your immune system stay strong.

2. Balance stress

• Occasional stress can impair gastrointestinal function and immune function. [2] Altering digestive enzyme and stomach acid secretions will impair your digestive and absorptive abilities, ultimately impacting your microbiome and hence your immune system.

3. Nourish the gut lining

• The amino acid glutamine is the main fuel for the cells that line the digestive tract. Studies have shown that this amino acid can positively affect gut health by supporting the gut microbiome and the gut lining’s integrity. [1] In order to provide benefit, look for a powdered and micronized L-glutamine, providing a highly absorbable form and an easier way to take the recommended 5 g per day.

4. Rebalance the microbiome

• The gut microflora signals the immune system during times of occasional stress. It also helps maintain healthy and balanced microflora within the digestive tract.* [3] Probiotic supplements have been shown to temporarily modify gut flora, helping to support healthy immune system function. [4]

5. Try a fiber supplement

• Fiber has been touted for several health benefits, including satiety, cholesterol and blood sugar balance within the normal range, and healthy bowel function.* A 12-week randomized, placebo-controlled, double-blinded trial published in 2022 showed that partially hydrolyzed guar gum supports healthy immune system function in healthy adults.* [5] This water-soluble dietary fiber is thought to influence immune function through the production of short-chain fatty acids (SCFAs), which regulate immune functions through their receptors.* [6]

Supporting gut health and implementing these tips can profoundly impact immune function and help support overall wellness!*
