When it comes to healthy habits<\/a>, my motto is simple: less is more. But it hasn\u2019t always been that way. It\u2019s taken years of unraveling unnecessary wellness \u201cnoise\u201d to realize that at the heart of it all, simplicity reigns supreme. Prioritizing fundamental, time-tested rituals<\/a> is what fosters genuine well-being. One practice that never gets old? Incorporating intentional supplements<\/a>. Specifically, those that target multiple bodily functions. Enter L-glutamine! It\u2019s the dynamo nutrient that goes the extra mile. We\u2019re diving into what it is, how it helps (everyone), and where to get it. Plus, get the specifics on L-glutamine and gut health. In the realm of practical wellness, it\u2019s one of the best-kept secrets.<\/p>\n

What is L-glutamine?<\/h2>\n
L-glutamine<\/a> is a powerhouse nutrient. It plays a crucial role in gut health, including building and repairing tissues. More specifically, it\u2019s a type of amino acid (the foundation of proteins<\/a>). L-glutamine acts as a crucial ally, involved in many functions\u2014especially as it pertains to digestive wellness, brain health, and immunity. It keeps intestines working properly and supports the body\u2019s ability to fight off infections and illnesses.<\/p>\n
Do we need L-glutamine?<\/h2>\n
Yes, but it\u2019s a non-essential amino acid<\/a>. Meaning (under normal circumstances), our bodies create enough L-glutamine to meet its basic needs. But in the event of stress, illness, or intense physical activity, we require more. Fortunately, certain foods and supplements fit the bill.<\/p>\n

Recommended Daily Allowance (RDA) for L-Glutamine<\/h2>\n
Fun fact: there isn\u2019t an established RDA for L-glutamine. That said, for general maintenance and gut health, a typical daily dose is 5-10 grams. If you engage in intense physical activity<\/a>, you may benefit from a higher dosage, like 10-20 grams per day (split into multiple servings). For specific conditions\u2014like IBS or during recovery from surgery or illness\u2014your healthcare provider might recommend doses ranging from 15-30 grams per day.<\/p>\n
Reasons to Increase Your L-Glutamine Intake<\/h2>\n
Sickness and exercise aside, there are plenty<\/em> of reasons to up your L-glutamine intake. We tapped Jewel Zimmer\u2014the founder of supplement brand, Juna<\/a>\u2014to get the low-down on why everyone benefits from L-glutamine.<\/p>\n

Why is L-glutamine important?<\/h3>\n
Because\u00a0of its reputation\u00a0for strengthening and repairing the gut lining! And this is vital for our daily exposure to environmental pollutants (which lead to bloating and digestive discomforts). L-glutamine also provides fuel for our metabolism, boosts immune health, modulates inflammation and\u00a0gut microbiota, and helps regulate cortisol. On top of all of this, it assists in collagen synthesis<\/a>. Last but not least, it\u2019s a\u00a0precursor\u00a0to GABA, the neurotransmitter that calms the brain.<\/p>\n
What do you wish more people knew about L-glutamine?<\/h3>\n
L-glutamine\u00a0(and other amino\u00a0acid supplementation) were key to my postpartum\u00a0mental health, and I don\u2019t\u00a0think we talk\u00a0about them enough.\u00a0<\/p>\n
Which Juna supplement is rich in L-glutamine?<\/h3>\n
Juna\u2019s Gut Therapy. We always say: change your gut, change\u00a0your brain, change your\u00a0life.<\/p>\n

How does L-glutamine support gut health?<\/h2>\n
While L-glutamine plays a multifaceted role in the body, let\u2019s hone in on gut health. After all, it\u2019s crucial for keeping our digestive system running optimally. <\/p>\n
\n
It\u2019s fuel for intestinal cells.<\/strong> The cells that line our gut use L-glutamine for energy. In turn, L-glutamine helps maintain the integrity of our intestinal lining, which is crucial for preventing conditions like leaky gut<\/a>.<\/li>\n
It supports immune function.<\/strong> Our gut houses a significant <\/em>portion of the immune system<\/a>. L-glutamine aids in the proper function of immune cells in the gut, enhancing our overall immune response.<\/li>\n
It promotes tissue repair.<\/strong> During times of stress<\/a> or injury, the body\u2019s demand for L-glutamine increases. This is particularly important for those with inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), or other gastrointestinal disorders.<\/li>\n
It balances mucosal barrier.<\/strong> L-glutamine maintains the first line of defense in the gut. And a healthy mucosal barrier is necessary for everything from nutrient absorption<\/a> to protecting against pathogens.<\/li>\n<\/ul>\n

Sources of L-Glutamine: Diet and Supplements<\/h2>\n
So, where can you get L-glutamine?<\/p>\n
Dietary Sources. <\/strong>Good news! L-glutamine is available in various foods\u2014particularly those high in protein<\/a>. Rich sources of L-glutamine include both animal and plant-based ingredients.<\/p>\n
\n
Animal products:<\/strong> Meat (beef and pork), poultry, fish, dairy products (milk, cheese, and yogurt), and eggs.<\/li>\n
Plant-based sources:<\/strong> Beans, lentils, spinach, cabbage, beets, parsley, and carrots.<\/li>\n<\/ul>\n
Supplements.<\/strong> L-glutamine supplements come in various forms, including powders, capsules, and tablets. They are widely available and can be a convenient way to ensure adequate intake\u2014especially if you have increased needs or follow a predominately vegetarian or vegan diet.<\/p>\n
Are you deficient in L-glutamine? <\/h2>\n
Unfortunately, identifying an L-glutamine deficiency is a bit complex. That said, certain signs and symptoms may indicate a potential deficiency. Here\u2019s how you can identify if you might need more L-glutamine in your diet:<\/p>\n
1. You have digestive issues.<\/h3>\n
\n
Frequent diarrhea:<\/strong> Chronic or recurrent diarrhea can deplete L-glutamine levels.<\/li>\n
Leaky gut syndrome<\/strong>: Symptoms such as bloating<\/a>, gas, cramps, and food sensitivities may be indicators of a compromised gut lining, where L-glutamine is crucial for repair and maintenance.<\/li>\n
Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD):<\/strong> Flare-ups of these conditions can be exacerbated by low L-glutamine levels.<\/li>\n<\/ul>\n
2. Your immune system isn\u2019t as robust as it used to be.<\/h3>\n
\n
Frequent infections:<\/strong> If you find yourself getting sick often, it might be due to a weakened immune system, which relies on L-glutamine to function properly.<\/li>\n
Slow wound healing:<\/strong> L-glutamine is essential for cell regeneration and repair, so slow healing of wounds can be a sign of deficiency.<\/li>\n<\/ul>\n3. You\u2019re losing muscle mass, coupled with fatigue.<\/h3>\n
\n
Muscle loss:<\/strong> Unexpected loss of muscle mass, particularly if you\u2019re engaged in regular physical activity, might indicate that your body is using more L-glutamine than it can produce.<\/li>\n
Chronic fatigue:<\/strong> Persistent tiredness and fatigue<\/a> (especially if it doesn\u2019t improve with rest!) can be a sign of low L-glutamine, as it\u2019s a critical energy source for many cells.<\/li>\n<\/ul>\n
4. You feel chronic stress and anxiety.<\/h3>\n
\n
Stress and Anxiety:<\/strong> L-glutamine plays a role in brain function and neurotransmitter production. Low levels can contribute to increased feelings of stress and anxiety.<\/li>\n<\/ul>\n5. You\u2019ve recently undergone a serious injury or physical trauma.<\/h3>\n
\n
Post-surgery recovery:<\/strong> If you\u2019ve recently undergone surgery or suffered from a serious injury, your body\u2019s demand for L-glutamine increases significantly.<\/li>\n
Intense exercise:<\/strong> If you\u2019re an endurance athlete or engage in heavy physical training, you likely have higher L-glutamine needs<\/a> and can become deficient if your intake doesn\u2019t meet demand.<\/li>\n<\/ul>\n
\n

Testing for L-glutamine Deficiency<\/h2>\n
While there\u2019s no standard test for L-glutamine deficiency\u2014as it\u2019s not typically included in routine blood tests\u2014chat with your healthcare provider about the following two options: amino acid profiling (a blood plasma test) or clinical assessment (medical history, dietary analysis, etc.).<\/p>\n
How to Address an L-Glutamine Deficiency<\/h2>\n
Whether you\u2019ve noticed certain signs and symptoms\u2014or you\u2019ve had a clinical assessment done, there are a few different ways to address an L-glutamine deficiency.<\/p>\n
1. Dietary adjustments<\/h3>\n
\n
Increase your protein intake:<\/strong> Ensure you\u2019re consuming enough high-protein foods<\/a> such as meat, fish, dairy, eggs, beans, and legumes.<\/li>\n
Include glutamine-rich veggies:<\/strong> Foods like spinach, parsley, and cabbage can also boost your L-glutamine intake.<\/li>\n<\/ul>\n2. Supplements<\/h3>\n
\n
L-Glutamine powder or capsules:<\/strong> Consider taking L-glutamine supplements<\/a>, particularly if you have increased needs due to stress, illness, or intense physical activity. Consult with your healthcare provider to determine the appropriate dosage<\/em>.<\/li>\n<\/ul>\n3. Manage stress and recovery<\/h3>\n
\n
Stress reduction:<\/strong> Implementing stress management techniques is key to reduce the body\u2019s L-glutamine depletion. Incorporate meditation<\/a>, yoga, and prioritize sleep.<\/li>\n
Post-exercise nutrition:<\/strong> Ensure you\u2019re getting adequate nutrition and recovery support after intense workouts, which can help maintain L-glutamine levels.<\/li>\n<\/ul>\n\n
