Vol 2017(Art ID 4164872): 13 pgs. doi: 10.1155/2017/4164872. -Longvida showed greater permeability when compared to unformulated 95% curcumin and significantly decreased A𝛽-induced reactive oxygen species (ROS) production, phosphorylated tau, and prevented apoptotic (cell) death at lower doses. These conclusions are supported by a previous pK study on Longvida and preclinical studies which showed enhanced bioavailability and permeability of Longvida compared to unformulated 95% curcumin extract, its benefits on neuroinflammation, and the ability to cross the BBB and other tissues in the body in the free form. This study showed additional evidence that Longvida has neuroprotective effects and might be more effective in controlling A𝛽42-exposed neuronal death, relative to 95% curcumin extract.

July 2015. 18(7): 786-792. doi: 10.1089/jmf.2014.0053 - As part of the Verdure Botanical Active Testing System (VBATS™), Longvida and Longvida® SD (Solution Dispersible) both reduced inflammatory markers NF-kB, TNF-a, and cytokines in immune-compromised cells (macrophages). The improved effects are thought to be due to an exponential increase in the 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 Unpublished.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.

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.

  • Frautschy SA et al. Omega 3 DHA and a bioavailable curcumin formulation (Longvida) synergize. 39th Annual Meeting of the Society of Neuroscience. Chicago, IL. 2009 Oct. Poster Presentation. - This study, NIH and VA funded, found a synergy existed when DHA and Longvida were taken in combination. UCLA authors wrote: “While DHA alone is very effective in vitro and with early interventions in vivo, effective late stage cocktail interventions in AD model mice with significant pre-existing pathology, neuron loss, and cognitive deficits are clearly dependent on the inclusion of the bioavailable lipidated curcumin.”

Efficacy of curcumin formulations in relation to systemic availability in the  brain and different blood compartments in neuroinflammatory and AD models. 39th Annual Meeting of the Society of Neuroscience. Chicago, IL. 2009 Oct. Poster Presentation. - Based on NIH funding, UCLA neuroscientists found that Longvida exhibited the best absorption after comparing different formulations including the use of lipids, antioxidants, nanoparticles, and cyclodextrins. Low-dose Longvida prevented the loss of hippocampal synaptoshysin, suggesting a role for Longvida in neurogenesis, the creation of new brain cells. This study established blood compartments other than plasma that are better indicators of tissue levels of free curcumin after Longvida dosing.
