ChromaDex Corp. (NASDAQ:CDXC) has announced the 11th published human trial on its patented NAD-boosting nutrient Niagen®, further highlighting its potential to support cardiovascular health in humans. A NIH funded study by Cardiology Division and Mitochondria & Metabolism Center at the University of Washington, published in The Journal of Clinical Investigation, found that Niagen supplementation reduced signs of inflammation, specifically inflammatory cytokines in vivo, in a smallgroup of end-stage heart failure patients. A second arm of the study, conducted ex vivo, found improved mitochondrial respiration and reduced inflammatory factor expressions in peripheral blood mononuclear cells (PBMCs) isolated from human subjects and treated with nicotinamide riboside.
“We found that increasing NAD levels with nicotinamide riboside suppressed inflammatory activation in end-stage heart failure patients,” says study co-first author Dennis Ding-Hwa Wang, M.D., Ph.D. “By increasing the mitochondrial health of PBMCs, proinflammatory cytokine production was reduced. These findings further support an important role NR may have in a variety of cardiovascular-related health declines.”
In this most recent study, conducted through the ChromaDex External Research Program (CERP™), patients with the most significant forms of heart failure (Stage D) were supplemented with NR to evaluate for improvements in inflammation. Their blood was analyzed for levels of pro-inflammatory signaling molecules, including IL-6, as well as the respiration rate of PBMCs in both in vivo and ex vivo models. PBMCs have been implicated in the inflammatory response that leads to the decompensation and worsening of heart failure. Mitochondrial health of PBMCs, as evidenced by the respiration rate, could be the culprit and reporter of the inflammatory process.
The pilot study found that both the respiratory rate of PBMCs, as well as levels of pro-inflammatory cytokine gene expressions, were all improved following daily NR supplementation for 5-9 days. In particular, expression of the NLRP3 inflammasome and cytokine IL-6 were reduced in these patients following NR supplementation.
“These new findings build upon a growing body of evidence identifying how Niagen may support cardiovascular health,” says Dr. Andrew Shao, ChromaDex Senior Vice President of Global Scientific & Regulatory Affairs. “We look forward to seeing the results from additional ongoing clinical research to further our understanding of Niagen’s impact on cardiovascular health.”
A previous trial on ChromaDex’s nicotinamide riboside (NR, or Niagen) published in Nature Communications in 2018 found that it reduced systolic blood pressure in pre-hypertensive patients relative to a placebo. While NR seems to have diverse benefits on cardiovascular health, further research is required to establish whether NR could play a role in preventing or slowing the progression of heart disease.
ChromaDex, the exclusive licensee of Dr. Charles Brenner’s patented NR, has since invested over $35 million in investigating, manufacturing and offering NR in the form of Niagen and has secured more than 20 patents. ChromaDex has demonstrated the safety and efficacy of Niagen in eleven published human trials (and over 20 additional ongoing studies further evaluating its safety and efficacy) and has achieved government regulatory acceptance in the United States, Canada, the European Union, and Australia.
