NAD+ Salvage Biology: studies examine how blocking nicotinamide methylation alters intracellular NAD+ concentration and downstream sirtuin activity
If levels of oxalate in the glomerular filtrate increase (hyperoxaluria) it can chelate Ca 2+ ions forming the insoluble compound, calcium oxalate
This direct delivery method is particularly beneficial for individuals with conditions that affect nutrient absorption, such as Crohns disease or pernicious anemia
