Researchers found that a form of vitamin b3 reduced the inflammation marker interleukin 8 levels by 53% after six weeks and 63% after 12 weeks in COPD patients.
RT’s Three Key Takeaways:
- Vitamin B3 Reduces Lung Inflammation: COPD patients treated with nicotinamide riboside, a form of vitamin b3, experienced a 53% reduction in IL-8 levels after 6 weeks, increasing to 63% after 12 weeks.
- Improved NAD Levels May Slow Cellular Aging: The study found that vitamin B3 raised NAD levels in COPD patients, which are linked to reduced DNA damage and slower cellular aging.
- Further Research Needed for Broader Application: While the results are promising, larger and longer-term studies are required to confirm the effectiveness of nicotinamide riboside as a treatment for COPD.
A new study from the University of Copenhagen and Bispebjerg Hospital suggests that a form of vitamin B3 may be the key to improving quality of life for patients with chronic obstructive pulmonary disease (COPD).
“In the study, we show that nicotinamide riboside, also known as vitamin B3, can reduce lung inflammation in COPD patients,” says associate professor Morten Scheibye-Knudsen from the Center for Healthy Aging at the Department of Cellular and Molecular Medicine, University of Copenhagen, who has co-authored the new study, in a release. “This is significant because inflammation can lead to reduced lung function in these patients.”
COPD patients have an increased risk of respiratory infections and pneumonia. For instance, influenza can lead to serious lung infection and, at worst, death.
The study is published in Nature Aging.
Reduced Lung Inflammation
The double-blinded, randomized, placebo-controlled study included 40 COPD patients and 20 healthy control subjects. The patients either received a placebo or the vitamin B3 in doses of two grams a day. The results showed a significant drop in the inflammation marker (interleukin 8 or IL 8) in patients treated with the vitamin B3. After six weeks, the researchers observed a drop in IL 8 levels of 53%, and this effect increased by 63% after another 12 weeks.
[Vitamin D Reduces COPD Exacerbations by Over 40%]
In other words, the group treated with vitamin B3 experienced reduced lung inflammation during the study.
“Even though the results are promising, we need to carry out more studies on larger populations to confirm our findings and to determine the long-term effects of nicotinamide riboside in treatment for COPD,” says Morten Scheibye-Knudsen in a release.
COPD and Accelerated Aging
The researchers also found that COPD patients have lower levels of NAD in the blood, which is associated with accelerated aging based on DNA methylation levels. Treatment with vitamin B3 resulted in higher NAD levels and showed signs of delaying cellular aging.
“As we age, we seem to metabolize a molecule known as NAD. The loss of this molecule is also seen after DNA damage, for instance the type of damage associated with smoking,” Morten Scheibye-Knudsen says.
This means that the molecule may influence the aging process, which makes it a possible target for future treatment—and, initially, for more studies. It is important not to jump to conclusions about the role of NAD in the aging process, though, the researchers caution as more research is required to fully understand the implications and possibilities of NAD.
“We hope this research will pave the way for new treatment options for COPD patients, but first we need to continue to analyze and validate the results in larger and more comprehensive studies. Only through thorough research will we be able to offer the best and most effective treatment to people suffering from this difficult disease,” he says in a release.
