The improved effects are thought to be due to an exponential increase in water solubility of Longvida forms versus regular curcumin.

  • Absorption of curcumin into lymph and plasma using an enhanced solid-lipid dose delivery form in rats. 2014. Unpublished. - It is well known that curcumin undergoes extensive first-pass metabolism yielding high amounts of curcumin-glucuronide in the blood after oral administration. The plasma and the lymphatic concentrations of curcumin are about 5-fold and 10-fold higher after administration of Longvida when compared to the standard curcumin suspension, respectively. The high amount of curcumin found in the lymphatic fluid after treatment with Longvida serves as explanation for its increased bioavailability when compared to the standard curcumin suspension.

DOI: 10.1074/jbc.M112.393751 - This National Institutes of Health (NIH) and Veterans Administration (VA) -funded research at UCLA published in this premier journal is believed to be one of the first to show a nutritional intervention can remove the highly toxic type of soluble tau in live models, which directly led to memory improvement. Also believed to be the first paper to show a substance can reduce the creation of new tau by modulation of the creation of ‘sticky’ or phosphorylated tau by heat shock protein in vivo. In this study, therapeutic brain levels of free curcumin were also detected after chronic low-dose Longvida dosing.
