Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme involved in hundreds of cellular processes, including energy metabolism, DNA repair, and cellular regeneration. However, NAD+ levels decline significantly with age, dropping by up to 50% by your 40s, which can contribute to fatigue, slower recovery, and signs of aging at the cellular level.*

Grail’s Eternal NAD+ Booster is a scientifically advanced dietary supplement designed to restore and maintain optimal NAD+ levels by supplying the body with the direct building blocks needed for NAD+ production.* It targets the root of NAD+ decline, supporting cellular restoration, resilience, and healthy aging.*

Unlike many NAD+ supplements that rely on precursors like NR or NMN that must first convert within the body, our formula features Bioenergy RiaGev®-WS™—a proprietary blend of Bioenergy Ribose® and nicotinamide ascorbate (a stable form of Vitamin B3). Using the salvage pathway for direct cellular absorption, it has demonstrated superior bioavailability and effectiveness in third-party clinical research, helping the body efficiently produce and maintain optimum NAD+ levels.*

In addition to supporting NAD+, Eternal also promotes the production of adenosine triphosphate (ATP), the body’s primary energy molecule, and glutathione, a master antioxidant that protects against oxidative stress and supports detoxification pathways. Together, these compounds help sustain youthful energy, promote cellular repair, and protect against age-related health conditions.*

This formula also supports healthy stress responses by helping maintain normal cortisol levels, a hormone released during physical or emotional stress. It promotes insulin sensitivity and supports healthy blood glucose levels, which are crucial for metabolic health as we age. Additionally, NAD+ plays a key role in brain cell function, and Eternal may help support memory, cognitive performance, and long-term brain health.*

Whether you’re looking to stay energized, recover faster, or support graceful aging from within, Grail’s Eternal NAD+ Booster offers comprehensive support for your body’s most essential cellular systems.*

*Daily Value not established.

Other Ingredients: hypromellose (capsule), microcrystalline cellulose, vegetarian leucine.

Minimum Recommended Use:
One capsule every morning.

Optimum Recommended Use:
For most individuals, we recommend two capsules every morning to more noticeably increase NAD+ levels. For those starting with very low levels of NAD+, three capsules every morning can be taken. Once desired levels of NAD+ have been achieved (typically 4–6 weeks), a reduced daily dosage of one to two capsules can be taken to maintain levels.

If you plan to take two capsules every morning, we recommend selecting the 60 capsule count at checkout (1 month supply).

Results may vary. Please see a healthcare professional to determine what dosage is right for you.

Lately, in my mid-40s, I’ve noticed it's become harder to find the motivation to work out like I used to. I’ve always tried to stay in decent shape and make time for exercise when I can, but over the last few years it’s been a real struggle to get myself to the gym, on the Peloton, or to do any kind of consistent workout. Even with healthy eating and an active lifestyle, my energy just hasn’t been the same.

I started hearing about this whole NAD thing and was super skeptical, but curious enough to look into it. There are so many options out there! I came across Grail on Instagram promoting their new NAD+ supplement. What grabbed me was the RiaGev-WS ingredient, which is supposed to survive digestion and get straight to your cells. I noticed a few other brands use RiaGev too, but Grail’s dosage was higher than most at 750 mg per capsule. The promo price seemed reasonable, so I figured why not and ordered the 60-count, planning to take two a day like they recommend.

Fast forward to now, I’m almost done with my first order, and honestly, I’m really impressed. After about two weeks, I started feeling less tired during the day and more refreshed in the mornings. I’ve been more motivated to get up and work out again, which feels amazing. It might be a coincidence, but even my focus at work seems a little sharper. Either way, I can tell something’s working in a good way.

All in all, I’d totally recommend Grail if you’re curious about NAD supplements. Their customer support was super quick to answer my questions, the product feels really high quality, and the capsules are easy to swallow with no weird smell. The price isn’t crazy compared to others I looked at. I just signed up for a subscription, so we’ll see how it goes, but so far, I’m loving it!

Hope this helps!!

NAD+ and the mitochondria

Your body consists of 37.2 trillion cells, each essential for maintaining health. Various cells perform specific functions throughout your body, but all require energy to carry out the repair processes managed by organelles called mitochondria.

Mitochondrial dysfunction is a key sign of aging. The mitochondria generate around 90% of the body's energy, fueling vital functions by converting nutrients into adenosine triphosphate (ATP). This energy production relies on a constant supply of NAD+.

an aging reality

NAD+ declines as we age

As we age, NAD+ levels can decline by up to 65% between the ages of 30 and 70, driven by increased oxidative stress, chronic inflammation, reduced recycling efficiency, and rising cellular repair demands. This depletion impairs the function of critical proteins like sirtuins and PARPs, disrupting genomic stability, mitochondrial performance, and energy metabolism. The resulting decline in cellular resilience contributes to fatigue, slower repair processes, and a higher risk of age-related diseases.

Boosting your NAD+ is vital for healthy aging

NAD+ is essential for cellular repair and regeneration, playing a key role in activating sirtuins—proteins that regulate cellular balance and promote repair. It also fuels PARPs, enzymes that help fix DNA damage from oxidative stress. Without sufficient NAD+, these critical repair systems cannot function effectively.

As we age, NAD+ levels naturally decline, a process worsened by physiological and immune stress. The body also produces fewer mitochondria, increasing strain on existing ones and accelerating aging. Fortunately, you can support mitochondrial health and combat cellular aging through mindful lifestyle choices and NAD+-boosting supplements.
