A recent metaanalysis (2024) found that oral collagen supplements increased skin hydration (SMD 1.25) and elasticity (SMD 0.61), with a common dose of 4 g/day
(2017) conducted a randomized, double-blind, placebo-controlled crossover trial in 40 healthy adults, showing that 15 mg/day HTY for 3 weeks significantly increased plasma thiols, total antioxidant status, and SOD1 expression while reducing nitrite, nitrate, and MDA, and modestly lowering body fat mass, supporting HTYs anti-atherosclerotic and cardioprotective potential via improved redox balance and gene expression modulation [77]
