This is the second study we’re sharing as part of NMN Week. One of the best things about NMN is that we’re still finding out new ways it can help our bodies. This week we’re sharing the newest, most exciting NMN developments with you.
Background
As we age, our bodies get worse at producing NAD+, the coenzyme responsible for cellular energy, DNA repair, and metabolism.
We know that this causes many problems all over the body including fatigue and memory fog, but we don’t know all of the issues it causes.
Scientists wanted to find out if NAD+ loss was linked to a particular problem that occurs in the blood vessels and damages the heart.
The Study
The researchers reduced NAD+ levels in human cells to mimic what happens when we age.
They saw that this caused the cells that line our blood vessels to create molecules which made the blood vessels get tighter.
Tighter blood vessels means that less oxygen gets around the body which further damages cells. Over time, it will also lead to heart problems as the heart needs to work harder to pump blood.
Scientists then applied NMN to the cells.
Not only did NAD+ levels increase back up to the level of a younger person, but the cells stopped producing the damaging molecules.
What this means for us
Heart disease is the leading cause of death, responsible for around 20 million deaths each year. It’s especially common in older people who have lower NAD+ levels.
Anything that can be done to reduce the threat of heart disease will have a huge benefit for human longevity.
Beyond this, the study provides yet more evidence of NMN increasing NAD+ levels in human cells!
We’ll be sharing the next instalment of NMN Week on Friday!
