However, further research is needed to investigate the appropriate dosing regimen to improve healthy adults cognitive function and physical performance [246,248]
By neutralizing free radicals, it prevents oxidative stress that contributes to hyperpigmentation and skin aging
It effectively stimulates GH release but it also raises cortisol (stress hormone), prolactin (reproductive hormone), and aldosterone (blood pressure regulator), and produces intense hunger (ghrelin-like appetite stimulation). For researchers, these off-target effects create experimental noise
The shift from surface treatments to cellular ones reflects a better understanding of why skin ages
