It is well known that our immune systems becomes less efficient as we age.
Research shows that low NAD+ levels may lead to impairment of the Innate Immune System which is our first line of defence against viral infection.
This is because NAD+ is fundamental to the activity of a group of proteins in our cells known as the “sirtuins”.
Increased activation of the sirtuins (via NAD+) has been shown to prevent viral replication, whilst inhibiting the activity of sirtuins encourages viral infections to progress.
Boosting your cellular NAD+ levels and sirtuin activity may therefore be a good way to boost your immune system and protect yourself from viral infections.
