5g straight L-Glutamine. No secrets. Recovery without the BS.

Core Nutritionals Glutamine keeps it simple with one ingredient: a full 5,000mg scoop of L-Glutamine, no hidden blends, no extra stuff getting in the way. That's a smart move. Lots of products bury glutamine in fancy mixes or hype it up for muscle gains, but Core does it right: one thing, a solid dose, total honesty.

L-Glutamine is the most common conditionally essential amino acid in your body – that means your body makes it, but needs more during tough times. Think heavy workouts, long sessions, dieting, sickness, gut problems, or just pushing hard – that's when demand spikes. It acts as a big nitrogen mover and fuel for fast-growing cells, like those in your gut lining (enterocytes) and immune fighters (lymphocytes). That's why it's still a player in sports supps. Not for packing on muscle if you're healthy and eating right – studies show it's not great for that. But it shines for recovery during stress, keeping your gut barrier strong, and boosting immune function when training ramps up.

That 5,000mg dose is spot on – it's the low end of the 5g to 15g range from studies. No skimpy amount here. It's a real daily scoop for gut and recovery vibes. You probably won't feel a big rush like with caffeine or pump stuff. Glutamine's more low-key. What you'll notice is how it slots into your recovery routine

Key Highlights

  • 5,000mg L-Glutamine per scoop – that's a real dose hitting the start of the 5g to 15g research range. Not some weak add-on; it's solid for athletes grabbing glutamine to help recovery, gut health, and staying strong during intense training.
  • Just one ingredient – no mixes, no mystery amounts, no label tricks. You see exactly what's in every scoop, making it easy to check against studies and stack with your other stuff.
  • Based on a conditionally essential amino – glutamine's the most plentiful in your body, but you might need extra during killer stress or workouts. Adding it helps when training and recovery push harder than your body can handle alone.
  • Helps your gut where it counts – glutamine fuels enterocytes, the quick-turnover cells lining your intestines. Great for athletes whose stomach gets wonky from hard training, trips, or strict dieting.
  • Backs up immune-heavy training – glutamine gets used a ton by lymphocytes and other immune cells. Makes it a smart add when your workouts crank up the body stress.
  • Keeps it real on the science – glutamine's useful, but not for everything. Studies back it more for gut strength, immune help in stressed folks, and recovery in tough spots than for muscle or fat loss in healthy people.
  • No prop blend nonsense – tons of recovery supps hide glutamine in amino piles, so you can't tell if it's enough. Here, the full 5,000mg is right there, standing alone.
  • Stacks easy with protein, EAAs, BCAAs, and hydration gear – glutamine plays nice with branched-chain aminos and electrolytes for better recovery. Use it after workouts or between meals without clashing.

Who Is This For?

  • Bodybuilders in big volume phases racking up damage and fatigue. The 5,000mg L-Glutamine gives a easy daily boost that fits around their training and food without clashing with pre or pump stuff.
  • Endurance athletes putting in long runs, rides, or cardio that stresses the whole body. Glutamine's role in gut and immune support makes this a go-to when miles and time add up.
  • CrossFit and functional folks doing back-to-back intense workouts with short rest. A clear 5g glutamine scoop adds smart recovery when training gets dense and hits digestion or readiness.
  • Lifters cutting calories for a show or shoot. Hard dieting ramps stress and can make gut stuff iffy, and glutamine's a solid pick for those phases.
  • Athletes who like building their own stacks over mystery blends. This gives exact control: a research-level glutamine dose to pair with creatine, EAAs, hydration, or protein without extras.
  • People whose stomach gets shaky in heavy training, travel, or big eating phases. Glutamine fuels intestinal lining cells (enterocytes), so it matches that need.

How to Use

Mix 1 scoop with water, a shake, or drink once a day. Post-workout or between meals is usually best, but consistency beats perfect timing since glutamine isn't a stim with a tight window. If you're new to amino powders or have a touchy gut, try half a scoop first to check it out, but 5g is standard and works for most. Shaker's easiest for mixing, but a spoon in liquid does the trick. Empty stomach or with food – both fine, doesn't mess with how it works. Stacks awesome with protein, creatine, EAAs, BCAAs, and electrolytes since it covers different ground. No need to cycle, especially in tough training stretches where you want it steady. Keep it cool and dry with the lid on tight for best powder.

What to Expect

First 0-10 minutes: mix and down it easy, no stim kick, no big feel expected. 10-40 minutes in: still no rush, since L-Glutamine isn't for energy or pumps; it's about recovery processes, not instant vibes. First few days: it's all about easy routine – nailing that 5g daily without hassle. Days 1-7: slots right into your recovery flow, especially with high volume or diet stress. Weeks 2-4: shines in steady support for gut cells and immune recovery during heavy stress. This is background help, not front-line performance, and that's why the right person will dig it.

Key Ingredients

  • L-Glutamine — 5000mg — Clinically aligned glutamine support for recovery and gut resilience

Frequently Asked Questions

How much glutamine is in each serving of Core Nutritionals Glutamine?

Each scoop provides 5,000mg of L-Glutamine. That matches the low end of the clinically used 5g to 15g range, making it a legitimate standalone dose rather than a token amount hidden inside a blend.

Is 5 grams of glutamine an effective dose?

Yes. Five grams is a research-relevant serving and a common starting point for athletes using glutamine for gut support, recovery support, and resilience during physically stressful training phases.

Will Core Nutritionals Glutamine help build muscle?

Not directly in the way creatine or adequate total protein intake do. The evidence does not support glutamine as a strong standalone muscle-building ingredient in healthy athletes, but it can still be useful for recovery support, gut lining support, and immune-demanding training periods.

What does glutamine actually do in the body?

L-Glutamine is the most abundant conditionally essential amino acid in the body and is used heavily by gut lining cells and immune cells. It also plays a role in nitrogen transport and whole-body amino acid metabolism, especially when physical stress is high.

When should I take Core Nutritionals Glutamine?

Post-workout is a common and practical option, but the most important factor is daily consistency rather than exact timing. It can also be taken between meals, with a protein shake, or at another convenient time in your routine.

Can I stack this with creatine or protein?

Yes. Core Nutritionals Glutamine stacks very well with creatine monohydrate, whey or isolate protein, EAAs, BCAAs, and hydration formulas because it serves a different role and does not duplicate their primary mechanisms.

Will I feel anything right away from this formula?

Probably not, and that is normal. Glutamine is not a stimulant, nootropic, or pump ingredient, so its value is in consistent recovery-oriented support rather than an immediate buzz or performance sensation.

Does this product contain a proprietary blend?

No. This is a fully transparent single-ingredient formula with 5,000mg of L-Glutamine per serving and no proprietary blend hiding the dose.

Is this a good option during a cut or contest prep?

Yes, that is one of the more sensible use cases. During calorie restriction and hard training, recovery stress and digestive fragility often increase, and glutamine is often used to support those systems.

Do I need to cycle glutamine?

No standard cycling protocol is required. Since glutamine is an amino acid used for recovery support rather than a stimulant or hormone-active ingredient, it is generally used continuously during demanding training blocks.

Clears breakout without playing around
Size: 5.5 Ounce (Pack of 1)
This face wash means business. It lathers up nicely and you can actually feel it working on your skin. After a few uses, my breakouts looked calmer and less angry, and my skin felt way cleaner overall. It can be a little drying if you overdo it, so moisturizer is a must, but if you’re dealing with stubborn acne, this one gets straight to the point. No fluff, just results.

Gave me hope again for my back acne
Size: 5.5 Ounce (Pack of 1)
I’ve been struggling with acne on my back since I was a teen and I’m now in my 30s and still struggling. I had taken accutane (several times) and it was the only thing that has cleared me but it always came back. I decided that I’m not gonna risk potentially hurting myself over that medication again and consistently (no matter if I didn’t feel like it!) started washing my back with this every night (even if I didn’t wash my hair). I would leave it on for at least 5 minutes and then rinse it off, then moisturize. After a month this has been the CLOSEST to clear my skin has ever gotten besides accutane. I’ve tried virtually everything. I was honestly surprised, and although it’s not perfectly clear, it’s made a significantttttt difference. It’s worth a try if you plan to be serious about it. I wish I would have taken a before picture, I just didn’t have high expectations at first!!

Can do wonders but also can completely strip your healthy skin barrier
Size: 5.5 Ounce (Pack of 1)
Awesome product ONLY IF YOU HAVE SEVERE BREAKOUTS AND OILY SKIN. STAY AWAY IF YOU HAVE SLIGHTLY DRY SKIN AND/OR MINOR BREAKOUTS- not worth the risk. I used it for back acne and it really helped. DO NOT MIX WITH OTHER ACNE PRODUCTS. But HUGE HUGE HUGE HUGE WARNING!!!!!—— This is NOT a great play for your face or truly anyone who doesn’t have severe acne and oily skin. Yes, it eliminates acne. If your face is extremely oil and acne prone, every few days would be fine. I, myself, always thought my face was a mix of oily and dry- but I had a lot of hormonal acne from birth control. At first, I would use this every few days (every other, every 3, depending), and I noticed it improving my facial acne as well. I used it for 3+ months. THEN *TRIGGER WARNING* I suddenly one day broke out in HIVES. It completely STRIPS YOUR SKIN BARRIER IF YOU OVERUSE IT OR IF YOUR SKIN IS NOT SEVERELY BROKEN OUT. Red, swollen, bumps, all over my face for a week straight. My face burned so bad I couldn’t even cry it hurt. I couldn’t sleep good. Couldn’t touch my face. Couldn’t even put on moisturizer. Not even an ice pack helped. I had to stop hot showers and every single facial product/makeup for multiple weeks to heal my face. I noticed after I stopped using it, it almost made my acne better on my face- like it truly did strip my skin barrier. I will no longer be putting this on my face UNLESS I have severe acne breakouts, and if that is the case it would be a ONE TIME use. I also DO NOT use it everyday on my back or chest, it’s more of an every other- every few days type of deal. BE ADVISED- does the job, but can also make things worse.
