What is L-Proline?
L-Proline is a Amino Acid supplement available in 1 form.
Not all forms of L-Proline are equal. The form you choose determines how much L-Proline actually reaches your tissues, and the difference between the best and worst forms can be substantial. L-proline is a conditionally essential amino acid and the primary component of collagen's triple helix structure, serving as the substrate for hydroxyproline synthesis that stabilizes collagen fibers. Research supports L-proline supplementation for promoting healthy collagen production, wound healing, and connective tissue integrity.
Forms of L-Proline Compared
L-Proline Preferred (Preferred Form) has a bioavailability rating of good absorption.
What the Research Shows
L-Proline is a non-essential amino acid that constitutes approximately 10% of total collagen content. Along with glycine and hydroxyproline, it forms the characteristic triple-helix structure of collagen. Research supports supplemental proline for wound healing, skin elasticity, and cardiovascular health via arterial collagen maintenance.
How to Choose the Right Form
