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 a substantial share 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 EatMe Supplements.

Key Benefits

• Muscle recovery — helps replenish glutamine 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, both of 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 rather than synthetic processing. Mutant holds the same quality standard here as across their EAA and BCAA range.
• Micronised for solubility — a smaller particle size means faster, more complete dissolution in water or shakes with no gritty residue.
• 100% pure, zero fillers — no additives, no flavouring, nothing unnecessary. Stacks cleanly with everything.
• Lab tested — Mutant tests ingredients at source.

How to Stack It

Glutamine is unflavoured and virtually tasteless, so it stirs into anything without changing the flavour. The most effective options:

• Post-workout recovery shake — add it to your protein shake straight after training for a combined protein and recovery hit.
• With your aminos — mix it into an EAA or BCAA drink for an intra or post-workout serve that covers aminos, 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 — athletes in heavy blocks often run 2–3 serves across the day, particularly during cutting phases when muscle preservation is the 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 drawn on so heavily by muscles, immune cells and the gut during training that dietary protein alone often can't keep pace with demand. Free-form glutamine replenishes stores faster than the glutamine in food because it doesn't require full digestion — it's 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 one of the most neutral-tasting supplements available, which is exactly why it disappears into any drink without affecting the flavour.

Can I take it on rest days?

Yes, and you probably should. Glutamine's role in immune function and gut health is ongoing rather than purely post-exercise, so consistent daily use is more valuable than dosing only around training.

Do I still need it if my EAA product already contains glutamine?

Many EAA formulas include a small amount of glutamine inside their support amino blend. A standalone glutamine is for people who want a higher dedicated dose on top of that, or who want to take it at specific times — before bed, for instance — without drinking a full EAA serve.
