Joint Fuel Liquid Concentrate is a scientifically advanced nutraceutical which contains cartilage and tendon building nutrition and helps maintain healthy joint function. It is in liquid form for easier digestion, absorption, assimilation and utilization.

It also contains Hydrolyzed Collagen Protein and Chicken II Collagen, the richest and most economical source of the amino acids Proline and Arginine. Proline is required for collagen synthesis and Arginine is a precursor of Nitric Oxide (NO). Nitric Oxide modulates tendon repair.
