If you regularly take NAD+ supplements then we have some good news for you. You can maximise how much NAD+ remains in your muscles by partaking in regular exercise. A new study has shown that exercise could be an effective way to boost your NAD+ especially in skeletal muscle. We know that our levels of NAD+ naturally decline with age - but this new research shows that we can help keep our NAD+ levels topped up by doing regular exercise. And it makes sense when you think about it. As we get older, we naturally become less active, less mobile and many of us abandon exercise altogether. Could this be one of the reasons why NAD+ decreases with age?
The studyThe study was led by Riekelt Houtkooper of the University of Amsterdam, and was published in Nature Aging. The researchers analysed 52 people, divided into four groups:
- 12 younger adults (aged 20-30)
- 17 older people (aged 65-80 who reported normal levels of physical activity)
- 17 “trained” older people (reporting above-average levels of physical activity, several hour-long exercise sessions per week)
- 12 older people (described as being physically impaired with very low physical activity levels)
