Overview
HMR's 4-in-1 chewable combines lignan, melatonin, biotin and milk thistle in a natural beef flavor, aimed at supporting normal cortisol levels and adrenal function in dogs, with secondary claims around skin, coat and digestive health.
With no seller description or spec sheet attached to this listing, the title is the only detailed source here, naming adrenal and cortisol support as the primary use and skin, coat and digestive health as additional benefits. The 90-tablet count suggests roughly a three-month supply at one tablet daily.

Who it's for
Owners looking for a single chewable that addresses adrenal support alongside general skin, coat and digestive wellness, rather than buying separate single-ingredient supplements.
