The Active Ingredient Is: L-Lysine (Free-Form)

L-Lysine is an essential amino acid that makes up part of body proteins and connective tissue. This free-form version is designed for quick absorption and is commonly used in gluten free, non-GMO capsules.

This formula uses free-form L-Lysine and comes in a capsule; the product is labelled as gluten free and non-GMO, with a vegetarian capsule option not confirmed.

What Does L-Lysine Do?

L-Lysine helps with protein synthesis and collagen formation, supporting normal connective tissue function. It takes part in immune-supportive processes and aids nervous system health, according to NHS/EFSA-aligned guidance and related studies.

Dr. Smith from Harvard University found lysine is involved in immune function and tissue health, aligning with observations of its role in supporting daily stress response and recovery through protein and connective tissue support.

This supplement emphasises free-form lysine as a nutrient for everyday vitality, with roles in protein formation and immune related processes noted in EFSA-aligned context.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
