Fact Meets Function

This animal study tested a combination of NMN (which boosts NAD+ levels) and apigenin (which prevents NAD+ breakdown) in aging mice. The combination helped preserve muscle mass, bone density, and cartilage health while improving exercise capacity. The treatment worked by maintaining cellular energy levels and supporting healthy gut bacteria that produce beneficial metabolites.

Researchers tested different formulations of hyaluronic acid sheets loaded with NMN to treat severe mouth sores that occur during cancer treatment. They found that 800 kDa hyaluronic acid sheets provided the best healing results in animal studies. The NMN-loaded sheets stayed in place well and released the compound steadily, showing promise as a safe treatment for painful mouth ulcers in cancer patients.

This study found that sepsis patients often develop persistent muscle weakness even after recovery, which is linked to damaged cellular powerhouses (mitochondria) in muscle tissue. Researchers discovered that NMN supplementation helped preserve muscle strength in septic mice by protecting these mitochondria. The treatment worked by supporting a key protein called SIRT3 that helps maintain healthy muscle cell energy production.

Researchers developed a targeted drug delivery system that uses NMN (a compound that boosts cellular energy) to treat kidney damage caused by reduced blood flow. In mouse studies, this system successfully delivered NMN directly to injured kidney cells, restored their energy production, and prevented both immediate kidney damage and long-term scarring. The treatment works by boosting NAD+ levels in kidney cells, which helps repair their cellular powerhouses (mitochondria).

This study found that aging causes an energy crisis in the intestines that disrupts production of HDL3, a beneficial cholesterol that protects the liver from inflammation. Supplementing with NMN restored intestinal energy production and HDL3 levels, which helped reduce liver damage and inflammation associated with aging. The research suggests NMN may help maintain healthy gut-liver communication as we age.

This animal study found that a high-fat diet increases alpha-ketoglutarate levels, which triggers a chain reaction that depletes NAD+ and NMN levels in immune cells. This depletion disrupts cellular energy production and increases inflammation, contributing to atherosclerosis (plaque buildup in arteries). The research suggests that maintaining adequate NAD+ and NMN levels may be important for cardiovascular health and controlling inflammation.
