Ingredients list

Complex L-Glycine

Made in the EU

All our supplements are manufactured in the European Union, where they meet the strictest standards and regularly undergo rigorous quality control.

We do all of this so that you can always rely on your supplements one hundred percent.

Complex L-Glycine is a naturally calming amino acid especially useful for athletes who want to fall asleep faster and wake up more recovered.

By supporting a gentle drop in core body temperature (a key signal that it’s time to switch into sleep mode) it helps you slow down at night, release tension, and quiet your head after a hard day. Each serving supports easier sleep onset and more stable rest, so you’re more likely to wake up with less fatigue and feel ready to perform again. 

The result is a clean, simple nightly tool that helps your body shift from stress to recovery - and makes sleep feel natural, not forced.

How does L-Glycine work?

L-Glycine acts in the brain as a calming neurotransmitter, helping to soothe the nervous system and relax the body before sleep.

It also lowers body temperature, which can help you fall asleep faster and achieve deeper, higher-quality sleep. As a result, you can wake up feeling more rested, with a clearer head and better recovery.

Can I take L-Glycine long-term?

Yes. L-Glycine is completely safe for long-term use, and your body does not build tolerance to it.

Will L-Glycine help me if I have trouble sleeping?

Yes, it can. L-Glycine helps calm the brain, relax the body, and improve sleep quality, making it easier to fall asleep and wake up feeling more rested.

However, it does not replace professional help or treatment for sleep disorders - if your issues are more serious, consult a doctor.

Will L-Glycine calm me down during the day too?

Yes. L-Glycine helps reduce nervous system tension and can make it easier to handle stress. You can take it during the day too if you feel overwhelmed or need to "switch your mind off" without losing energy.

Does L-Glycine have any side effects?

No. At the recommended dose, it’s completely safe. Unlike some sleep medications, it does not cause dependence, fatigue, or daytime drowsiness.
