Research further shows that Lactoferrin and CoQ10, whether administered alone or in combination, were discovered to restrain the progression of sarcopenia by inhibiting both protein metabolism and mitochondrial energy metabolism, and compared to groups treated with lactoferrin or CoQ10 alone, the combined treatment demonstrated varying degrees of improvement across all evaluated metrics, such as Lean Mass (2.273 ~ 5.365%), Fat Mass (−1.058 ~ −0.359%), GAS index (0.259 ~ 0.335%), Maximum Limb Muscle Strength (6.83 ~ 53.498 g), Inverted Grid Time (563 ~ 859 s), Exhaustion Time (386 ~ 468 s). Here, LTF is linked to sarcopenia.
