more (or less) water. No bitter aftertaste, no clumps, just a light,
slightly creamy blend (thanks to our liposomal technology) and a
refreshing hit of hydration.

How to use

response to stress

Health starts in your cells

NAD+ Boosting

Meet NAD+, a coenzyyme in our cells, responsible for energy metabolism, cellular repair and more. As we age, NAD+ declines—this decline is linked to age-associated diseases, from cognitive decline to cancer1. Targeting cells with our hero ingredient, Nicotinamide Riboside (NR), we can boost NAD+ levels in the body, thereby boosting your health and longevity.


Antioxidant Packed

No matter how healthy our lifestyles, our bodies get stressed by things that are out of our control. Those stressors create free radicals in the body, which wreak havoc on our cells. Packed with antioxidants—including the body’s master antioxidant, glutathione—Longevity can neutralize those free radicals, detoxify our cells, and protect our health.


More Absorbable

Form matters: The majority of the supplements we take can’t be broken down by the digestive system or absorbed into our bloodstream. So, we encase our glutathione in liposomes to disguise it as any other cell. With our liposomal technology, glutathione is 100 times more absorbable, which means your body is actually benefitting from our antioxidant-packed formula.



Many aging-associated diseases
can be slowed down and even
reversed by restoring NAD+
