Excellent 4.8

L-glutamine is an amino acid (a building block of protein) that your body can produce on its own. It also occurs naturally in foods like meat, eggs, and dairy. Of all amino acids, glutamine is the most abundant in your blood. You'll also find it in your muscles, gut, and even your immune cells. Since your body uses it in many places at once, there are times it may need more than it can make on its own.

Our L-glutamine is 100% pure, plant-based fermented, and easily dissolves in water or a shake.

✅ 100% pure: Just L-glutamine, with no unnecessary additives.

🌱 Plant-based: Fermented from a natural, non-animal source.

🥄 Easy to mix: Clean taste and easy to use.

It's as if the benefits of coffee come together with the taste of hot chocolate to create a delicious, healthy drink. The Original (sweetened) version has a mildly sweet, natural taste. The Unsweetened version contains no sweetener or salt for a pure flavor experience.

Mix 1 scoop (5 grams) with water, juice, or another drink of your choice. Taking it on an empty stomach may improve absorption, but there’s no solid evidence yet to confirm this.

Your questions
Answered Clearly

We’re here to give you clear and straightforward answers. No fluff, just the facts.

Any questions?

Amino acids are the building blocks of protein. There are 20 in total. Some are considered “essential,” which means you need to get them from food. Others are “non-essential,” meaning your body can produce them on its own. L-glutamine is a non-essential amino acid, but in certain situations, your body may need more than it can make. In those cases, it becomes a “conditionally essential” amino acid: normally not essential, but needed under specific circumstances.

L-glutamine always has a slight taste. If a brand claims it’s completely neutral, that’s not true. We tested many options, and this one had the least aftertaste while meeting the highest quality standards.

L-glutamine is generally well tolerated. At higher doses, some people may experience mild stomach discomfort.

Final production always takes place in the Netherlands, so we stay in full control of quality and safety. We source our ingredients directly from the origin, always from specialists who are best at what they do.

For every ingredient, there’s someone in the world who does it better than anyone else, and that’s who we work with. No middlemen. Only trusted suppliers who meet the strictest European standards.

At Clearly, our mission is simple: to keep searching for the #1, and make it available to you.

Because it’s clearly the inside that counts.

No flashy design or misleading labels, just a transparent pouch, so you can see exactly what’s inside. Too often, we buy things because they look or sound good… but inside? Sugar, fillers, or low-quality ingredients.

At Clearly, we do it Clearly: only #1 ingredients you can trust, and a fully transparent formula.

We use mono-material one single type of plastic, which makes the pouch 100% recyclable. Unlike most packaging that mixes paper and plastic and can’t be properly recycled.

When it comes to health, the inside matters most. That’s Clearly.

Yes. Every ingredient is lab-tested for heavy metals, microbiology, and other potential contaminants.

We only use clean, traceable raw materials from trusted suppliers who meet the highest European safety standards.

If it’s not safe, tested, and the best it’s not Clearly.

We don’t go for “good enough” we go for #1 quality.

We use our own products daily. And just like you, we only want the best.

Because if your health is #1, what you take should be too.

If you’re pregnant or breastfeeding, we recommend checking with your doctor before taking any supplement. During this time, both your health and your baby’s health are clearly #1.

With a Routine, you get 15% off and your products are delivered automatically at the interval you choose. You can pause, cancel, change the frequency, or add products anytime through your account.

Maria R. 5/5 Verified August 4, 2026

Ik voel me fitter.

C. B. 5/5 Verified December 21, 2025

Je l'ajoute chaque soir à ma tisane pour dormir, pour ma digestion et mes intestins. Il est absolument sans goût. Parfait.

Petra F. 5/5 Verified November 6, 2025

My new coffee corner! I love every single add-on to my coffee or should I say NOT coffee, with the mushroom mix? Premium ingredients are such a peace of mind, I feel great after workout and I’m serene, focused and ready for the day 🙌🏼 thank you Clearly.

Lidia E. 5/5 Verified August 27, 2025

Affordable product, easily soluble in water, taste is very pleasant, quite neutral, slightly sweet. I am buying my 3rd package and will continue to use this product.

Ivana T. 5/5 Verified June 15, 2026

I take it mixed with warm water every morning on empty stomach to help my stomach and intestinal lining and to help with leaky gut. I repeat one more time during the day.

Alena S. 5/5 Verified June 3, 2026

Heeft geen rare smaak, lost heel makkelijk op. Ik ben benieuwd hoe goed het resultaat gaat zijn in de toekomst, ik gebruik het voor mijn darmen. De producten zijn allemaal heel kwalitatief dat is iets wat ik 100% zeker ben

Laurens D. 5/5 Verified April 8, 2026

Excellent product, mild, almost neutral flavor, dissolves very well. Delighted with Clearly products, clean and pure ♥️

Candela D. 5/5 Verified April 15, 2026

Makkelijk te mixen en effectief voor darmwand!

Arnold D. 5/5 Verified March 25, 2026

I do feel an improvement with L-glutamine, and now I'm ordering Colostrum. I feel safe with your products. Thank you!

Susy S. 5/5 Verified May 11, 2026

I really like the Product! Good taste dissolves well! And good recovery effects!

Oliver T. 5/5 Verified April 2, 2026

Creo que me ayuda mucho en mi problema con el colón irritable que me da con estreñimiento. Me lo estuve tomando durante los meses de Diciembre y Enero y mis digestiones fueron muy bien... Luego se me acabó a finales de Enero y en Febrero me dio una crisis, entre que pude hacer el pedido de nuevo y me llegó he vuelto a estar estreñida y con muchos gases... Ahora llevo tomándomelo unos días y parece que todo me vuelve a funcionar correctamente. De todas formas sigo investigando... Lo que menos me gusta es que los pedidos tardan mucho en entregarse... En Correos se quedan frenados y a veces tardan varios días.

Anabel G. 4/5 Verified March 8, 2026

Ik slik het nog maar een maand, maar heb al zoveel minder buikpijn. Ook merk ik dat ik meer energie heb. Dit blijft zeker een vast onderdeel van mijn routine.

Vania D. 4/5 Verified March 5, 2026

Zeer fijn product! Ook de smaak is goed! Heel neutraal na andere merken jaren gebruikt te hebben is de L-glutamine van Clearly echt beter

Marja H. 5/5 Verified January 20, 2026

It tasted neutral and I love it

Gloria D. 5/5 Verified March 23, 2026

I'm using this product for a longer period. It is cheap but very good quality, tastes good and dissolves very well in a glass of water.

Ivana T. 5/5 Verified August 18, 2026

Great product. I like that is has no weird taste and I feel I haven't gotten sick since I take it. I'm very satisfied with it also regarding the price

Ira H. 5/5 Verified December 19, 2025

De L-glutamine voelt goed aan, smaakt goed (wat niet bij alle merken het geval is) en laat geen 'gekristalliseerde sterretjes' achter in je glas.

Sophia G. 5/5 Verified December 22, 2025

Perfecte kwaliteit /prijs

Harry Jacobus R. 5/5 Verified August 5, 2026

Good quality, easily soluble in water, affordable, slightly sweet taste.

Amanda H. 5/5 Verified December 22, 2025

Pije juz chyba 2 tydzień rano na czczo żeby pomoc mojemu układowi trawiennemu odbudować się po cięzkim wirusie żołądkowym. Czuje, że mi to pomaga bo nastapiła bardzo szyka poprawa. Jestem fanką produktów Clearly.

Natalia B. 5/5 Verified June 23, 2026

Good product, I use it everyday.

Brian I. 5/5 Verified February 4, 2026

Goede kwaliteit!

Rick V. 5/5 Verified December 20, 2025

Me encanta :)

Jelena K. 5/5 Verified December 29, 2025

I prodotti Clearly sono ottimi, ben presentati e deliziosi😁. L-glutamina mi aiuta molto con l'intestino e mi da una ottima riserva di energia 💪. Not Coffee al contempo mi da una carica e concetrazione che non mi sarei mai aspettato senza parlare del buon umore appena sveglio🤩🥳! Un miracolo. Li consiglio vivamente a chi vuol combattere il brainfog e come me ha bisogno di stare concentrato e di buon umore a lungo ☺️. Chiedo gentilmente allo staff di Clearly se fosse possibile sapere se i prodotti sono con o senza glutine. Grazie per i vostri prodotti, mi aiutano tantissimo 🙏

Ilaria M. 5/5 Verified December 4, 2025

Doet wat het moet doen. Geen toegevoegde supplementen; gewoon puur en van goede kwaliteit

Ir H. 5/5 Verified November 29, 2025

Grote verpakking voor een goede prijs, helpt met IBS :)

Hannah S. 5/5 Verified November 16, 2025

I guess this is supposed to be good for the gut I don’t see a big difference even after taking morning and night for 2 months Hoping it will do something in the long term though

Torja N. 3/5 Verified November 16, 2025

Good support for mussles!

Victor Q. 5/5 Verified November 6, 2025

Felt improvements in just a few weeks.

Erica D. 5/5 Verified November 1, 2025

I am consuming it with colostrum because I had gut issues. Immediately noticed a huge difference in my health

Safa E. 5/5 Verified October 31, 2025

Van mijn orthomoleculair arts kreeg ik het advies om L-glutamine te nemen. Eerst van een ander merk besteld, maar toen kwam ik deze tegen bij Clearly. Een stuk goedkoper dan het andere merk, maar volgens mij met dezelfde goede werking.

Irene V. 5/5 Verified October 18, 2025

M’n buik voelt vele malen rustiger

Aline S. 5/5 Verified October 14, 2025
