Why L-Glutamine Deserves a Spot in Your Stack

June 04, 2025

If you’ve been training hard, sweating more, or just feeling run down lately, there’s one supplement that might be missing from your routine, and it’s probably not what you think.

Enter: L-Glutamine. This unflavored amino acid might not have the hype of pre-workout or creatine, but when it comes to recovery, gut health, and performance, it’s a quiet powerhouse. And you definitely need it.

Let’s break down what it is, why it matters, and how to easily add it to your daily stack.

What Is L-Glutamine, and Why Should You Care?

L-Glutamine is the most abundant amino acid in your body. It plays a major role in:

Muscle recovery after training
Immune system support during stress
Gut health and digestion
Cell repair and overall resilience

Even though your body produces glutamine naturally, intense workouts, illness, stress, or dieting can naturally deplete it, which is where supplementation comes in.

5 Reasons to Add L-Glutamine This Summer

1. Better Muscle Recovery

Glutamine helps reduce post-workout soreness and speeds up repair so you can bounce back faster between sessions. This can be especially helpful during outdoor runs, lifting, or summer training programs.

2. Supports Gut Health

Glutamine helps maintain the lining of the intestinal wall, making it essential for digestive health, especially if you deal with bloating, irregularity, or a high-protein diet.

3. Boosts Immunity During Travel or Stress

Traveling this summer? Your immune system can take a hit with long flights, changing time zones, or inconsistent eating. Glutamine helps your body stay strong and resilient.

4. Unflavored = Stack-Friendly

You can mix BioHealth Nutrition’s unflavored L-Glutamine into any shake, smoothie, or even just water. There's no weird taste and no clash with your other supps.

5. Supports Lean Muscle Goals

If you’re in a cutting phase or working toward lean gains, glutamine helps preserve muscle tissue while supporting fat loss. A subtle but strategic edge in your stack.

How to Use L-Glutamine

Suggested use:
Take 1 scoop (5g) post-workout or before bed. It can also be taken during fasting windows for added recovery and gut support.

Pro tip: Stack with your post-workout protein like Precision ISO protein or Creactive for a powerful recovery combo.

Why Summer Is the Best Time to Start

Higher temps = more sweat = more nutrient loss. If you're active outdoors, attending events, or dialing in your diet, now is the perfect time to give your recovery system a boost.

And if you're feeling run down, inflamed, or sluggish? Glutamine might just be the recovery reset your body is asking for.
