Provided are methods for improving exercise performance and endurance of a mammal, comprising administering to the mammal in need thereof a composition comprising dihydroberberine (DHB), or an analog or derivative thereof, and a physiologically acceptable carrier. DHB in the composition can serve as an antioxidant to defend red blood cells against oxidative stress damage, by scavenging reactive oxygen species generated during to increase the deformability and the survival of red blood cells.

Methods for improving exercise performance and endurance thereof

The present invention provides novel methods for anti-glycation, especially mitigating or preventing skin aging in a mammal, the method includes administration to the mammal of a composition including an effective amount of dihydroberberine (DHB) or its analog or its derivatives. The present invention also provides a composition including an effective amount of dihydroberberine (DHB) or its analog or its derivatives, for mitigating or preventing 'Maillard reaction' in a mammal by controlling blood glucose, scavenging chronic ROS, reducing a level of MDA and expression of MMP-1. In addition, the present invention provides method for preparing any compositions disclosed herein.

Use of dihydroberberine or its derivatives for anti-glycation

Among others, the present invention provides methods and compositions for controlling blood glucose or weight, including a combination of (i) a therapeutically effective amount of berberine (BBR), or a pharmaceutically acceptable salt, acid, ester, analog or derivative thereof, including dihydroberberine (DHB); and (ii) vitamin B12. The combination effectively ameliorates BBR or DHB side effects, including VB12 reduction, gastrointestinal discomfort, and slowed bowel movements, by promoting transcobalamin II receptors synthesis, decreasing homocysteine levels and maintaining intestinal balance, including short chain fatty acids content, gut microbiota diversity and richness.

Combination of berberine and derivatives thereof, and vitamin B12

The present invention provides compositions and methods for promoting glycogen synthase activity and augmenting glycogen storage capability in muscle tissue and/or liver tissue in a mammal, relating to administration to the mammal of an effective amount of β-aminoisobutyric acid (BAIBA), an analog or derivative thereof, or a pharmaceutically acceptable salt, ester, acid, polymer, analog or derivative thereof.

Compositions and methods for promoting glycogen synthase activity and augmenting glycogen storage capability

The present invention provides methods, compositions (e.g., eyedrop or spongarion composition), and uses for alleviating and preventing age-associated vitreous degeneration in a mammal, comprising administrating to the mammal in need thereof a therapeutically effective amount of L-ergothioneine, an analog or derivative thereof, or a pharmaceutically acceptable salt, acid, ester, polymer, analog or derivative thereof, as an active ingredient. In particular, L-ergothioneine is capable of scavenging chronic reactive oxygen species directly and radically to mitigate and prevent HA depolymerization and HA decreasing-viscosity in the mammal's vitreous body; and/or improving vitreous liquefaction in the mammal.

Use of L-ergothioneine to ameliorate and prevent age-related vitreous degeneration

The present invention provides novel methods for enhancing muscle function in a mammal, the method includes administration to the mammal of a composition comprising therapeutically effective amount of dihydroberberine (DHB) or a pharmaceutically acceptable salt, acid, ester, analog or derivative thereof. The present invention also provides a composition including therapeutically effective amount of dihydroberberine (DHB) or a pharmaceutically acceptable salt, acid, ester, analog or derivative thereof, for enhancing muscle function. In addition, the present invention provides methods for preparing any compositions disclosed herein.
