Mutant Glutamine

Mutant Glutamine — 100% Pure Vegan Fermented L-Glutamine

Glutamine is the most abundant free-form amino acid in muscle tissue — and one of the first depleted by hard training. During intense sessions, muscles can lose up to 50% of their glutamine stores, undermining recovery, immunity and gut health in the hours that follow. Mutant Glutamine replenishes those stores with 5g of 100% pure, vegan fermented, micronised L-glutamine per scoop — zero fillers, zero flavours, lab tested, 60 serves per 300g tub. In stock at TopDog Nutrition.

Key Benefits

• Muscle recovery — glutamine helps replenish stores depleted during training, supporting repair and reducing breakdown in the recovery window.
• Immune function — glutamine is a primary fuel source for immune cells, which come under particular pressure during hard training blocks and calorie deficits.
• Gut health — supports the integrity of the intestinal lining and digestive function, which can be compromised by intense training and high-protein diets.
• Anti-catabolic — helps reduce the muscle breakdown driven by cortisol release during and after training.

Why Micronised Vegan Fermented Glutamine?

• Vegan fermented source — derived from plant-based fermentation, not synthetic processing. Mutant uses the same quality standard here as with their EAA and BCAA products — no shortcuts on source.
• Micronised for solubility — smaller particle size means faster, more complete dissolution in water or shakes with no gritty residue.
• 100% pure, zero fillers — no additives, no flavouring, no unnecessary ingredients. Stacks cleanly with everything.
• Lab tested — Mutant tests ingredients at source.

How to Stack It

Glutamine is unflavoured and virtually tasteless — stir it into anything without changing the flavour. The most effective stacking options:

• Post-workout recovery shake — add to your protein shake immediately after training for a combined protein and recovery hit.
• With GEAAR — mix into Mutant GEAAR for an intra or post-workout drink that covers EAAs, electrolytes and glutamine recovery support together.
• Before bed — a 5g serve before sleep supports overnight recovery when growth hormone is naturally elevated.
• Multiple daily serves — serious athletes in heavy blocks often run 2–3 serves across the day, particularly during cutting phases when muscle preservation is a priority.

Directions

Add one level scoop (5g) to 240ml of cold water, your protein shake or any other drink. Stir or shake for 5–10 seconds. Use post-workout and/or before bed daily. On heavy training days, a second serve intra-workout alongside your aminos is a common addition.

Frequently Asked Questions

Why does glutamine matter if I'm already eating enough protein?

Protein provides amino acids, but glutamine specifically is so heavily drawn on by muscles, immune cells and the gut during training that dietary protein alone often can't keep up with demand. Free-form glutamine supplements replenish stores faster than the glutamine found in food because they don't require full digestion — they're absorbed directly.

Is it suitable for vegans?

Yes — 100% plant-based vegan fermented glutamine, no animal by-products.

Does it have any taste?

Virtually none — it's genuinely one of the most neutral-tasting supplements available, which is why it disappears into any drink without affecting the flavour at all.

Can I take it on rest days?

Yes — and you probably should. Glutamine's role in immune function and gut health is ongoing, not just post-exercise. Daily consistent use is more valuable than taking it only around training.

How does it compare to glutamine in GEAAR?

Mutant GEAAR includes glutamine as part of its amino support blend. Standalone Glutamine is for athletes who want a higher dedicated glutamine dose on top of their EAA or BCAA product, or who want to stack it separately at specific times (like before bed) without taking a full EAA serve.
