Effervescent tablets (Fizzy tablets) have the active ingredients in solution before you drink them, thus allowing for rapid absorption and often a faster onset of action compared to swallowing a solid tablet.

NAD+ precursors such as Nicotinamide Riboside are the building blocks of NAD. Studies show that Nicotinamide Riboside efficiently and consistently raises blood NAD+ levels and is more readily converted by your body than other NAD+ precursors. 

Active B Vitamins play critical roles in many body processes. They serve as cofactors for enzymatic reactions, and are necessary for gene expression, oxidation-reduction reactions, energy production, detoxification, and formation of other biologically essential compounds. All the B Vitamins play a role in mitochondrial function, and deficiencies may be associated with oxidative stress and mitochondrial damage. Although many of the B Vitamins are present in the diet particularly in an era of “food fortification,” a large portion of the population still experiences deficiencies, particularly of Vitamin B6, Vitamin B12, and Folate.
