ABSTRACT: Dietary factors play an important role in human health.
Specifically, nutritional interventions may have an impact on the
hypothalamic-pituitary axis resulting in positive health outcomes. A
retrospective health status survey of 386 respondents was conducted to
investigate the potential of a dietary supplement, NutrifiiTM Renew, for improving various health outcomes in comparison
to a multivitamin/mineral control group. Among those who ingested Renew, 95%
reported experiencing at least some improvement in one or more health categories. Compared to the multivitamin/mineral group, the
Renew group reported earlier and/or greater improvements in several health
status categories including sleep, reproductive health, memory, energy/stamina,
skin and hair quality, flexibility, exercise recovery and feeling rested in the
morning. A clear majority (84.9%) of Renew consumers reported experiencing
noticeable improvement in some aspect of their health within one month. Among those who felt an improvement in sleep, most
reported experiencing a change within one week. These improvements were likely
due to the synergistic effects of L-arginine, L-citrulline, L-lysine, and
botanical extracts on nitric oxide production, growth hormone (GH) release, and
sleep quality. The observed improvements in skin elasticity and hair growth may
be related to increased GH levels and IGF-1 production. Overall, these findings
suggest that Renew may have potential as a dietary intervention for improving
various health outcomes beyond those provided by multivitamin/mineral
supplementation alone. Further studies are needed to confirm these findings and
elucidate the underlying mechanisms of action.
