Our Flavors
Flavored by a taste specialist, Longevity is naturally sweetened with
Stevia, so you can make it as sweet as you like by dissolving it into
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.
PEACH LEMONADE
Light and refreshing, like freshly-picked berries with tang of citrus
BERRY LEMONADE
Bright and delicate, like a summer peach with a squeeze of lemon
How to use
For best results, we recommend dissolving one scoop into at least
four ounces of water in the morning (or other liquid of your choice,
like a smoothie or yogurt). Do not take on an empty stomach or exceed
one scoop per day—because Longevity was intentionally formulated
and indicated.

response to stress, preventing and even reversing the risk of age-related
disease.

HOW IT WORKS
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.
ACCORDING TO A 2020 REVIEW
Many aging-associated diseases
can be slowed down and even
reversed by restoring NAD+
levels.¹

Everything you need,
nothing you don’t
Scientifically formulated with 10 potent ingredients, Longevity is packed with antioxidants and anti-aging agents to prevent—and potentially reverse—age-related decline, from wrinkles to cognitive function to disease. No fillers, no fluff. But don’t take it from us: Vet our ingredients for yourself.
THE INVESMENT
Invested in your health
If you’re anything like us, you know your supplements. So, what’s stopping
you from filling your Amazon cart with each of our research-backed
ingredients? In short, our potency and our price can’t be beat. We’ve
formulated Longevity with a leading orthomolecular expert to deliver the
potency you need for the results you want. And unless you’re okay with
popping 10 pills a day for $300+ a month, one scoop of Longevity
a day is easier, cheaper and better for your health.

Longevity's ingredients have been rigorously tested for quality and the formula has been endorsed by one of Germany's leading gastroenterologists

Purity, potency and precision
From banking to watchmaking, we all know Switzerland for
its exacting standards and precision execution—and it’s no
different in the biotech industry. That’s why we manufacture
Longevity in an FDA-registered laboratory in Neuschatel,
Switzerland. You can’t have science without precision.
