Recover-Me stimulates the bone metabolism and growth
“Osteoporosis” literally means “porous bones.” The bones become weaker, increasing the risk of fractures, especially in the hip, spinal vertebrae, and wrist. Bone tissue is constantly being renewed, and new bone replaces old, damaged bone. In this way, the body maintains bone density and the integrity of its crystals and structure. Bone density peaks when a person is in their late 20s. After the age of around 35 years, bone starts to become weaker. As we age, bone breaks down faster than it builds. If this happens excessively, osteoporosis results.
The amino acid arginine is a crucial factor for bone creation as among other things, it supports the production of collagen. Collagen is a protein which is the basic component of various connective tissues (such as cartilage) and bone. In this way, arginine supports growth of the osteoblasts where bone mass is formed.
As studies show (see below) essential amino acids, such as L-arginine (Arg) and L-lysine (Lys), are involved in bone metabolism and growth.

Arginine supplementation in the prevention and treatment of osteoporosis.
Oral administration of L-arginine in pharmacological doses induces growth hormone and insulin-like growth factor-I responses and stimulates nitric oxide synthesis. Growth hormone and insulin-like growth factor-I are important mediators of bone turnover and osteoblastic bone formation, while nitric oxide is a potent inhibitor of osteoclastic bone resorption. Because of this dual effect on physiological regulators of bone remodeling, L-arginine could potentially increase bone formation over bone resorption, and, consequently, increase bone mass. It is, therefore, hypothesized that oral supplementation of L-arginine may be a novel strategy in the prevention and treatment of osteoporosis. Studies of this simple, safe, and inexpensive therapy seem warranted.
Arginine and Lysine Have Positive Effect on Osteoblasts In Vitro
Human osteopenic bone-derived osteoblasts: essential amino acids treatment effects.
The development of in vitro cell culture methods has made it possible to study bone cell metabolism and growth and obtain a deeper insight into the pathophysiology of common orthopedic diseases such as osteoporosis. After analyzing the effect of two essential amino acids, L-arginine (Arg) and L-lysine (Lys), in previous in vitro and in vivo studies, the present authors investigated the administration of Arg and Lys in osteoblasts derived from human osteopenic bone. After isolation, osteoblasts were cultured in DMEM supplemented with either Arg (0.625 mg/ml/day, Arg Group) or Lys (0.587 mg/ml/day, Lys Group), or both of them (Arg-Lys Group), whereas the Control Group was sham-treated. After 7 days the following parameters were tested in all groups: MTT proliferation test, Alkaline Phosphatase (ALP), Nitric Oxide (NO), Calcium (Ca), Phosphorus (P), Osteocalcin (OC), C-Terminal Procollagen type I (PICP), Interleukin-6 (IL-6), Transforming Growth Factor-beta 1 (TGF-beta 1), Platelet Derived Growth Factor (PDGF) and Insulin-Like Growth Factor-I (IGF-I). Results were compared with those obtained from human healthy bone to verify the effect of the amino acids on osteoblasts derived from pathological tissue. In addition, a comparison was also made with the results obtained from rat osteopenic bone to assess reliability of the in vitro model. The current results support previous findings and indicate that Arg and Lys stimulation has a positive effect on osteoblast proliferation, activation and differentiation. Therefore, administration of these amino acids may be useful in clinical treatment and prevention of osteoporosis.
