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.

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.
