Key Points to Remember

  • Glutamine represents 60% of the free amino acids in muscles.
  • It accelerates recovery after exercise.
  • Stimium offers certified products for optimal quality.
  • This amino acid also strengthens the immune system.
  • Ideal for athletes of all levels.

What is L-Glutamine?

What if a single amino acid could boost your recovery and immunity? Present in large quantities in your body , it acts as an invisible fuel for your cells.

A key amino acid for the body

Classified as "non-essential," it becomes crucial during intense stress. Why? Your body produces it naturally, but not always enough during prolonged exertion.

Its main role:

  • Feed intestinal and immune cells (70% of their energy!).
  • Support muscle repair after training.

Synthesis and natural sources

Your body produces it mainly in the muscles (60% of reserves) and the lungs. But certain contexts increase your needs:

  • Intensive training or competitions.
  • Injuries or periods of stress.

Where to find it? In animal proteins (meat, fish) or vegetable proteins (legumes). At Stimium , we also offer a pure version from organic vegetable fermentation , ideal for filling gaps.

The Benefits of L-Glutamine for Athletes

After exercise, your muscles need a boost to regenerate. This amino acid acts as an invisible ally to optimize your recovery and performance . Here's how it supports you.

Accelerated muscle recovery

A study (PMID 30108163) shows a 23% reduction in muscle soreness. How? By stimulating glycogen synthesis, essential for replenishing your energy stores.

Stimium Tip : Combine 5g of this amino acid with our Instant BCAAs for a synergistic effect.

Performance improvement

Marc, a semi-pro runner, improved his recovery by 30% in two weeks. Timing is key: take it within 30 minutes of your workout.

Compared to BCAAs, it specifically targets cellular recovery , ideal for intense efforts.

Reduction of fatigue

Physical stress and fatigue associated with overtraining are alleviated. Our RGN3 Reload formula combines this amino acid with electrolytes for a complete recharge.

The result? Less muscle aches and more energy to keep going.

L-Glutamine and Gut Health

Did you know that your gut is your second brain? This key organ influences your energy, your immunity... and even your athletic performance. Glutamine acts as an essential fuel for maintaining health, especially during intense exercise.

Strengthening the intestinal barrier

Think of your gut barrier as a protective shield. When you train hard, that shield can weaken. A recent study (2021, PMID 34977110) shows that this amino acid improves its resistance by 40%.

Did you know? Endurance athletes are more prone to leaky gut syndrome. A 10g/day protocol for 6 weeks helps repair tissue.

Role in intestinal permeability

What if your digestive problems stem from an overly porous intestinal barrier ? Glutamine tightens the junctions between cells, limiting inflammation.

Stimium Tip : Combine it with our Absolu Probiopure probiotics for optimal synergy. Sarah, a triathlete, confirms: "No more bloating during races!"

Microbiota support

Your microbiome is home to billions of friendly bacteria. This amino acid feeds the good bacteria, creating an ideal balance for your digestive system .

Caution : Choose anti-doping certified products, such as those from Stimium, to avoid fake supplements.

L-Glutamine and the Immune System

Your immune system is your invisible shield against germs, especially when you push your body to the limit. This amino acid acts as emergency fuel for your immune defenses , crucial when training intensifies.

Fuel for your cells

Immune cells (lymphocytes, macrophages) consume up to 70% of their energy through this amino acid. Without sufficient reserves, they slow down like an engine without gas.

Did you know? A study on marathon runners (2018) shows a 45% reduction in ENT infections with appropriate supplementation.

Protect your body during exercise

Endurance athletes are more vulnerable to viruses. Why? Physical stress temporarily weakens the immune system .

  • Our "Winter Without Virus" program : combines this amino acid with vitamin C and zinc for maximum synergy.
  • Concrete example : Julien, a marathon runner, avoided catching a cold before his race thanks to a preventative treatment.

Stimium Offer : Discover our Immunity Pack with OMG3 and Ashwagandha to strengthen your natural defenses. Pro tip : "Start two weeks before a major competition" – Dr. Lefèvre, Stimium partner.

Food Sources of L-Glutamine

Some foods hide unsuspected nutritional treasures. To maintain your energy levels and support your recovery, here's where to find this key amino acid.

Animal proteins are the queens of the ranking:

  • Chicken (3.6g/100g) – Ideal in a post-workout salad.
  • Beef (2.8g) – Choose lean cuts.
  • Milk (1.2g) – Perfect in a protein smoothie.

L-Glutamine Deficiency: Signs and Solutions

Your body sends signals when it's running low on fuel. After an ultra-trail, your reserves can drop by 50% (2020 study). Here's how to spot the warning signs and respond effectively.

7 signs that should alert you

A deficiency often manifests itself through:

  • Recurring night cramps
  • More frequent infections (colds, flu)
  • Persistent fatigue despite rest
  • Digestive problems after exercise
  • Abnormally long recovery times
  • Unexplained drop in performance
  • Difficulty concentrating

Home test: Rate your fatigue on the Borg scale (1 to 10). Above 7/10 without an obvious reason, monitor your intake .

Express recharge protocol

If you have obvious symptoms , this 10-day program is effective:

  1. 5g in the morning on an empty stomach
  2. 5g right after training
  3. 3g before bedtime

Stimium Solution: Our coaches create a customized program with nutritional monitoring. Pierre, a trail runner, testifies: "In 72 hours, I regained 80% of my energy!"

Safety alert: Exceeding 15g/day requires medical advice. Our premium supplement guarantees optimal dosage without risk.

The secret of athletes

For endurance , needs differ. A marathon runner consumes up to 40% of their reserves. Our BCAA Endurance includes a dose adjusted to last the distance.
