*Percent Daily Values are based on a 2,000 calorie diet. Your daily values may be higher or lower depending on your calorie needs.

The Core Ingredient Is: L-Glycine

L-Glycine is a basic amino acid used by your body for everyday functions and as a building block for proteins. This product uses a plant-based capsule containing pure L-Glycine.

The capsule shell is plant-based, and the product is made in Germany under vegan, allergen-free standards with non-GMO ingredients and independent verification, ensuring ingredient transparency

What Does L-Glycine Do?

L-Glycine helps to support collagen formation, antioxidant status through glutathione synthesis, and muscle recovery by contributing to protein synthesis and serving as a creatine precursor. It also helps to support DNA, red blood cell, and heme synthesis, and can act as a calming neurotransmitter to support sleep and cognitive function, with evidence discussed in accessible reviews.

Scientific insights suggest these roles help to maintain normal connective tissue health, antioxidant defences, and metabolic function in everyday wellness. Glycine’s functions align with widely recognised nutrient roles in collagen-related processes and cellular protection.
