Men with high levels of anabolic hormones less likely to develop worsening frailty

The researchers found that having higher baseline levels of vitamin D, insulin-like growth factor-1 (IGF-1) and its binding protein 3 (IGFBP3) was associated with a lower risk of worse frailty status four years later. "Vitamin D, besides maintaining bone health, regulates muscle function, and low vitamin D levels are linked to lower muscle mass and strength. IGF-1 affects muscle growth and repair, and its action and levels are modified by its carrier protein IGFBP3," Swiecicka said.
Also linked to a lower likelihood of frailty status worsening were higher baseline levels of the hormone dehydroepiandrosterone sulfate (DHEA-S), but only in the oldest men. Several potential pathways could link DHEA-S with frailty. Swiecicka said, "DHEA-S may have direct anabolic effect on muscle, and, more recently, its neuroprotective and immune system-modulating effects have been described."

Nelson where do you aim to keep your vitamin d levels at when measuring ng/ml?
