Life Extension NAD+ Cell Regenerator™ and Resveratrol Elite™, 30 vegetarian capsules

NAD+ is a coenzyme critical to healthy cellular metabolism.^1,2 NAD+ is found in every cell in yLife Extension's body, where it facilitates energy production and other systemic functions.³

NIAGEN® nicotinamide riboside

NIAGEN® is a patented, clinically studied form of nicotinamide riboside, a compound that helps increase levels of the NAD+ coenzyme. This is important because the NAD+ coenzyme is necessary for creating adenosine triphosphate (ATP), the compound yLife Extension's body uses to create cellular energy.^2,4

NAD+ plays a critical role in metabolism and the production of cellular energy, but NAD+ levels have been shown to decline with age.^1,2,5 In a randomized controlled trial published in 2019, adults taking 300 mg of nicotinamide riboside (as NIAGEN®) had a 51% increase in blood levels of NAD+ after 2 weeks.⁶

Trans-resveratrol

Resveratrol is a well-known healthy aging nutrient.⁷ Life Extension's Resveratrol Elite™ formulas contain trans-resveratrol, the form associated with beneficial biological effects.^8-11 Resveratrol also promotes healthy insulin sensitivity, supports a healthy inflammatory response and has been shown to promote healthy endothelial function for a healthy cardiovascular system.^10,12-14

A more bioavailable resveratrol

We’ve combined resveratrol with galactomannan fibers from fenugreek seeds. This makes Life Extension's Resveratrol Elite™ formulas up to 10 times more bioavailable.¹⁵ This means that the trans-resveratrol in this product reaches higher levels in yLife Extension's bloodstream and circulates longer than traditional, unformulated resveratrol.

Resveratrol and heart health

One way that resveratrol can promote heart health is by helping to shield yLife Extension's cells from oxidative stress.¹⁶ Resveratrol also promotes endothelial health and function—an essential component of living a long, healthy life.¹⁴

Resveratrol and brain health

At the same time, resveratrol has shown an ability to help the brain and cognition: in a randomized controlled trial, it encLife Extension'saged healthy neurological function as well as brain blood flow. These are additional ways in which resveratrol can bolster even more essential aspects of healthy aging.¹⁷

Augmenting resveratrol with quercetin

Life Extension's formula also delivers quercetin, a phytonutrient that complements resveratrol. In a randomized clinical study, researchers compared the formulated Bio-Quercetin to unformulated quercetin. They found that the quercetin formulated with fenugreek fibers led to serum levels of total quercetin up to 62 times higher than unformulated quercetin, and 18 times higher levels of free (unconjugated) quercetin.¹⁸

Quercetin promotes both cardiovascular and endothelial health and helps maintain healthy blood pressure already within the normal range.^19,20 Quercetin is also a potent inhibitor of oxidative stress and helps promote a healthy inflammatory response.^21,22

Quercetin promotes a healthy immune response in the face of seasonal immune challenges. In a randomized clinical trial, quercetin encLife Extension'saged a healthy immune response in physically fit older adults.²³

Bio-fisetin

By combining fisetin with fenugreek fibers, we’re able to create a fisetin formula that is up to 25 times more bioavailable.²⁴
