L-proline is an amino acid. Scientists call it an “imino acid” or a “secondary” amino acid because of its unique chemical bonding structure as an essential element to collagen — a supportive protein for skin, bones, tendons, and connective tissue, supporting their health and healing. L-proline can develop internally without relying on foods and supplements. Your body generates it from an amino acid called glutamic acid and other amino acids. Because of this, it’s considered a “non-essential” amino acid as “essential” amino acids cannot generate from your body. You need to supplement them or eat foods containing them.

But the “secondary” and “non-essential” labels don’t mean L-proline is unimportant — quite the opposite. L-proline is a beneficial component that plays a crucial role in the human body.

Proline is an essential ingredient in collagen. It makes up about 15 percent of proline. Why is collagen so important? As mentioned earlier, it’s the building block of tendons, bones, connective tissue and skin. Eating protein-rich foods can increase proline and collagen levels, as can supplements. Another critical point is vitamin C needs to be present for your body to assimilate the L-proline. Its benefits include:

  • Healthy, Youthful Skin
  • Enhances Athletic Performance
  • Cardiovascular Repair
  • Healthy Joints
  • A Good Gut
