Under normal conditions your body produces enough — but intense exercise, catabolic stress and calorie restriction push demand well beyond what the body can synthesise, making supplementation conditionally essential. ATP Science L-Glutamine is 100% pure L-Glutamine, HPLC-verified for purity and potency, tested for allergens, pesticides and heavy metals, vegan, gluten-free and GMO-free. 5g per serve, 500g (100 serves) or 1kg (200 serves), in stock at TopDog Nutrition.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Glutamine Becomes Essential Under Training Stress\u003c\/h3\u003e\n\u003cp\u003eGlutamine is classified as conditionally essential — your body can make it under normal circumstances, but its demand in catabolic conditions (heavy training, calorie restriction, illness or injury) consistently outstrips synthesis capacity. When this happens, plasma glutamine levels fall, and the cells that depend on glutamine as their primary fuel source — intestinal enterocytes, immune cells and liver hepatocytes — begin to compete for limited supply. The result is slower recovery, compromised gut integrity and suppressed immune function, all of which are common complaints among athletes in hard training blocks.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMuscle recovery\u003c\/strong\u003e — glutamine provides nitrogen for protein synthesis, supports tissue repair and helps reduce muscle soreness in the days following intense training.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmune support\u003c\/strong\u003e — immune cells use glutamine as their primary energy substrate. Supplementing during heavy training periods helps maintain immune function when plasma levels are under pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGut health and integrity\u003c\/strong\u003e — intestinal enterocytes (the cells lining the gut wall) depend on glutamine as their main fuel source. Adequate glutamine supports intestinal barrier integrity, which matters for nutrient absorption and reducing gut permeability under training stress.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnti-catabolism\u003c\/strong\u003e — glutamine helps protect muscle tissue during periods of high training load or calorie restriction by supporting nitrogen balance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEndurance support\u003c\/strong\u003e — during prolonged exercise, glutamine participates in gluconeogenesis (glucose production from non-carbohydrate sources), helping to maintain blood glucose when carbohydrate stores are depleted.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eATP Science Quality Standards\u003c\/h3\u003e\n\u003cp\u003eATP Science sources glutamine from a manufacturer that permits audits of their facility and provides full traceability.

ATP Science recommend stacking it with their \u003ca href=\"\/products\/atp-science-noway-collagen-protein\"\u003eNOWAY!® Collagen Protein\u003c\/a\u003e post-training for a comprehensive recovery drink — the collagen provides structural protein for connective tissue and joints while glutamine covers the recovery and immune support angle. It also stacks cleanly with creatine, BCAAs or any protein powder.\u003c\/p\u003e\n\n\u003ch3\u003eDirections\u003c\/h3\u003e\n\u003cp\u003eMix approximately 5g (one heaped teaspoon) with 200–300ml of water or your post-workout shake. For standard recovery support, take once daily before or after training. For high-load training blocks, nutritionists recommend 5g up to three times daily — morning, pre-training and post-training. Stimulant-free and calorie-free; timing is flexible.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003ch4\u003eDo I need to cycle off glutamine?\u003c\/h4\u003e\n\u003cp\u003eNo — glutamine is safe for continuous daily use at standard doses. It's a naturally occurring amino acid, not a stimulant or hormonal compound. There's no evidence that cycling provides any benefit.\u003c\/p\u003e\n\n\u003ch4\u003eCan I take it on rest days?\u003c\/h4\u003e\n\u003cp\u003eYes — and you should during heavy training blocks. Gut and immune function don't stop needing glutamine support on off days, and recovery from the previous session continues well past the training session itself.\u003c\/p\u003e\n\n\u003ch4\u003eIs it suitable for women?\u003c\/h4\u003e\n\u003cp\u003eYes — no gender-specific contraindications. Useful for any athlete in periods of high training load, calorie restriction or recovery from injury.\u003c\/p\u003e\n\n\u003ch4\u003eCan I add it to hot drinks?\u003c\/h4\u003e\n\u003cp\u003eGlutamine is relatively heat-stable compared to some amino acids, but for maximum purity and effectiveness ATP Science recommend mixing into cold or room-temperature drinks rather than hot liquids.\u003c\/p\u003e","brand":"ATP Science","offers":[{"title":"500g","offer_id":44587498537049,"sku":null,"price":44.9,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1513\/5678\/files\/ATPGlutamine.png?v=1787891061","url":"https:\/\/topdognutrition.co.nz\/products\/atp-science-l-glutamine","provider":"TopDog Nutrition","version":"1.0","type":"link"}
