- Santos-Parker JR et al. Geront. Dec 2015. 55(Suppl 2): 195. DOI:10.1093/geront/gnv554.01 - Longvida® administered at a dose of 2000mg/day (n=16), or placebo (n=13) for 12 weeks increased brachial artery flow-mediation dilation (FMDba) by 34% and forearm blood flow in response to incremental brachial artery infusions of acetylcholine (FBFach) by 44% in middle-aged and older (MA/O) adults (45-74 yrs). Findings support supplementation with Longvida improves endothelial-dependent dilation (EDD) in MA/O adults mediated, in part, by an increase in nitric oxide bioavailability.
- Rafii MS et al. Front Behav Neurosci. 2015. 9: 1-11. - When there has been no way to look directly at amyloid in the brain, retinal amyloid imaging, retina being part CNS, could be a tool to demonstrate presence of plaques in the brain. In line with previous findings, this study supports Longvida® quickly labeling retinal beta amyloid and inducing fluorescent plaque in the neural layers of the retina of humans.

The trial recruited 60 subjects aged 60-80, and found daily Longvida® (400mg) led to significant improvements in cognitive function versus the placebo group. Excellent safety was reported, including no dropouts or reports of gastrointestinal upset. Significant improvements were observed in measures for memory, attention, fatigue, stress and mood as soon as one hour after the first dose.

DOI: 10.1155/2017/4164872. -Longvida showed greater permeability compared unformulated 95% curcumin and significantly decreased A𝛽-induced reactive oxygen species (ROS) production, phosphorylated tau, and prevented apoptotic 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, ability to cross BBB and other tissues in the body in 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.

Poster in 252nd ACS National Meeting: Philadelphia, PA. 2016 Aug. P55. - Longvida® enters the lymphatic system via chylomicrons; from lymphatic circulation, free curcumin is released into systemic circulation. Five times higher relative bioavailability of free curcumin in plasma and10-fold higher concentrations of free curcumin in lymph after administration of Longvida® when compared to the standard curcumin, further confirms lymphatic transport.

- Nahar PP et al. University of Rhode Island, J Med Food. 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 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.

- Ma et al. J Biol Chem. 2013 Feb 8. 288(6): 4056-65. 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.
- Dadhaniya et al. Food Chem Toxicol. 2011 Aug. 49(8): 1834-42. - This study is one of the few published long-term dosing trials looking at the safety of enhanced forms of curcumin.

Unpublished. - Early data from this ongoing study funded by the Singapore government showed improvement in brain cell health marker glial-fibrillar acidic protein (GFAP) after 1 week of feeding Longvida in p25 mice, which are bred to exhibit chronic neuroinflammation and tau abnormality. GFAP is the key marker for gliosis occurring as a result of brain damage, head trauma, inflammation and neurodegeneration.
- Frautschy SA et al. 39th Annual Meeting of the Society of Neuroscience. Chicago, IL. October 2009. - This study, also 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.”
- Frautschy SA et al. 39th Annual Meeting of the Society of Neuroscience. Chicago, IL. October 2009. - 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.
