Why L-Glutamine Might Be the Gut Repair Supplement You Never Knew You Needed

Let’s talk about gut health.

If your digestion has been off, you feel bloated after every meal, your mood is low for no obvious reason, or your energy just doesn’t bounce back the way it used to…


Your gut could be the culprit.

As a Nutritional Medicine Practitioner with over 11 years of experience specialising in gut health, I’ve seen it again and again: people chase symptoms like anxiety, fatigue, and food intolerances, but never realise their gut lining is damaged — until we test.

Now, one of the most underrated but powerful tools I use to support that healing?
👉 L-Glutamine

 

What is L-Glutamine?

L-Glutamine is an amino acid — a building block of protein — and it’s also the

primary fuel source for the cells lining your intestines

In simple terms:
- It’s like bricks and mortar for your gut wall.
- If your gut lining is damaged or inflamed, glutamine helps rebuild it.

Your body does make glutamine naturally, but when you're under stress, eating poorly, or dealing with inflammation (hello, modern life), your demand often outweighs your supply.

Signs your gut might need help:

  • You feel bloated, gassy, or heavy after eating

  • You’ve developed new food sensitivities or skin flare-ups

  • You’re often anxious, foggy, or fatigued

  • Your immune system feels weak

  • You’ve taken antibiotics, antacids, or the pill in the past

  • Those with histamine intolerance

If any of that sounds familiar, supporting your gut lining is step one — and L-Glutamine is often a game-changer.

Any L-Glutamine Supplement Recommendation?

BioActiv’s L-Glutamine

Not all supplements are created equal. I only recommend L-Glutamine to my client when it’s pure, easily absorbed, and clinically dosed.

That’s why BioActiv is my go-to. It’s pharmaceutical-grade, unflavoured, and contains no fillers or additives. Making it gut-friendly, even for sensitive clients.

I’ve seen BioActiv’s L-Glutamine help with:
✅ Calming gut inflammation
✅ Reducing bloating
✅ Supporting gut healing after food poisoning or antibiotic use
✅ Easing sugar cravings
✅ Improving mental clarity through gut-brain connection

But don’t self-diagnose!

Here’s the thing: bloating doesn’t always mean a leaky gut. And fatigue doesn’t always mean a supplement is the solution.

That’s why I never recommend guessing, especially when it comes to your gut. I always start with a personalised conversation and, if needed, recommend testing to get to the root cause.
