Your Circadian Rhythm Works Around the Clock

Energy production, cognitive function, metabolism, hormone signaling and cellular maintenance all follow biological rhythms.

Supporting these connected systems strengthens the foundation behind daily performance, not only sleep.*

FAQs

Questions about Rythm

RYTHM™ is a daily cellular health, energy and longevity formula.

It contains some of the most important daily health essentials such as Vitamin D, K2, CoQ10, with NAD+ precursors, cellular support, and antioxidants.

Instead of targeting one isolated pathway, Rythm contains 10 nutrients that work across interconnected systems involved in how well you produce energy, protect your cells, maintain healthy metabolism, and support biological repair as you age.*

It’s so much more than a multivitamin and NAD+ booster– it’s a complete support infrastructure for mental and physical performance, and healthy aging.

You could.

But you'd need a multivitamin, an NAD+ precursor, a methylation complex, CoQ10, vitamin D3, K2, B2, and luteolin, ergothioneine, spermidine and boron across multiple bottles every morning. It would be overwhelming, and much more expensive to take these all separately.

More importantly, RYTHM™ wasn't created by randomly combining popular longevity ingredients.

The formula was built around how key nutrients complement one another across connected biological systems.

10 ingredients. 7 cellular systems. 2 capsules. Once daily.

Most longevity supplements are formulated with 1 main headline ingredient: NAD+, NMN, an amino acid or antioxidant.

RYTHM™ takes a systems approach.

Its ingredients work across NAD+ metabolism, mitochondrial energy production, methylation, antioxidant defense, cellular renewal, healthy inflammatory balance, and bone and vascular health.

Longevity isn't one pathway. Your supplement shouldn't treat it like one.

RYTHM™ isn't a stimulant, so don't expect a caffeine-like rush.

It's designed to support the cellular systems behind energy production, physical resilience and cognitive function, while simultaneously supporting longer-term cellular maintenance and healthy aging.*

Some of the most important things happening aren't necessarily things you immediately “feel”, like supporting NAD+ levels, antioxidant defenses, autophagy, and healthy vascular function.

With consistent use, expect to feel more naturally energized, sharper focus, better immunity, and generally more “switched on.”

Think daily biological optimization, not a temporary energy shot.

Yes, but it's deliberately much more than that.

RYTHM™ provides 300 mg of Nicotinamide Riboside (NR) as an NAD+ precursor.

But increasing NAD+ is only one piece of cellular energy metabolism.

That's why NR is paired with TMG, Riboflavin-5'-Phosphate and CoQ10 to support the metabolic and mitochondrial machinery surrounding NAD+.*

The result is a more complete approach than simply putting an NAD+ precursor in a capsule.

Because producing NAD+ and producing cellular energy aren't the same thing.

CoQ10 plays a direct role in the mitochondrial electron-transport chain - the machinery your cells use to produce ATP.

That's why RYTHM™ combines:

NR → supports NAD+ availability
Active B2 → supports mitochondrial enzyme reactions
CoQ10 → supports electron transport and ATP production

Together, they create a more complete cellular-energy system.

Yes - but not in the traditional sense.

There's no caffeine and no stimulant-based energy system.

RYTHM™ supports energy where it actually originates: inside your cells.

NR supports NAD+ production, Riboflavin-5'-Phosphate supports enzymes involved in cellular energy metabolism, and CoQ10 participates directly in mitochondrial ATP production.*

No spike. No crash. Just support for the systems responsible for producing energy in your body and brain.

Yes, but not in the conventional sense.

RYTHM™ wasn't designed to stimulate your brain for a few hours. It supports key systems relevant to long-term brain and cognitive health, including mitochondrial energy metabolism, antioxidant defense and healthy inflammatory signaling.*

Luteolin, ergothioneine and CoQ10 provide complementary cellular and neurological support, while NR and active B2 support cellular energy metabolism.

Think of it as supporting the biology behind a high-performing brain, rather than creating temporary stimulation.

Because your circadian rhythm governs much more than when you sleep.

24-hour biological rhythms influence energy metabolism, hormone signaling, mitochondrial function, immune activity and cellular repair. NAD+ metabolism itself interacts with circadian signaling.

RYTHM™ is therefore designed as a daytime cellular-health formula, supporting energy and metabolic processes that naturally operate according to daily biological demand.

Think of each morning dose as your daily “on switch”, naturally supporting your biology’s most optimal energy cycle.

In the morning, with breakfast or first meal.

This is the most ideal timing for RYTHM™, timing your dose with the natural rising of daytime’s biological rhythm.

Taking it with food is optimal for fat-soluble nutrients such as vitamins D3 and K2 and CoQ10.

Daily consistency for your dose matters more than an exact hour of the day.

Spermidine supports one of the most interesting processes in healthy aging: autophagy.

Autophagy is essentially cellular housekeeping- the regulated process through which cells break down and recycle damaged or dysfunctional cellular components.

RYTHM™ pairs spermidine with NR, CoQ10 and ergothioneine to support both sides of cellular maintenance:

It protects healthy cellular structures while supporting the recycling and removal of damaged cells.*

Ergothioneine isn't just another generic antioxidant.

Humans possess a dedicated transporter that actively moves ergothioneine into tissues, and it accumulates in tissues exposed to substantial metabolic and oxidative demands.

RYTHM™ provides 10 mg ErgoActive® L-Ergothioneine to support cellular and mitochondrial protection from oxidative stress.*

It complements CoQ10, luteolin and the body's own antioxidant systems rather than simply duplicating them.

Luteolin is a naturally occurring flavonoid selected for its ability to influence multiple cellular pathways involved in oxidative stress, inflammatory signaling and neurological resilience.*

Research shows that luteolin can help modulate inflammatory signaling while supporting antioxidant defenses in the brain, an important cellular system involved in the response to oxidative stress. These pathways are particularly relevant to the cognitive function, where high metabolic activity in the brain creates substantial demand for both energy production and cellular protection.

Within RYTHM™, luteolin works alongside ErgoActive® ergothioneine and CoQ10 to provide complementary cellular support: CoQ10 supports mitochondrial energy metabolism, ergothioneine provides specialized antioxidant protection, and luteolin supports the signaling pathways involved in maintaining a healthy inflammatory and oxidative balance.*

The result is a more complete approach to protecting the high-energy cells responsible for cognitive performance and long-term neurological health.*

Because B2 isn't in RYTHM™ simply to tick a vitamin box.

Riboflavin-derived cofactors are involved in mitochondrial electron-transfer reactions and cellular energy metabolism. Riboflavin also supports glutathione reductase, an enzyme involved in regenerating the body's own antioxidant glutathione.

In other words, it helps support the machinery around NR and CoQ10, which is precisely why it's in the formula.

RYTHM™ doesn't treat Vitamin D as a standalone nutrient- it combines it with the cofactors that help your body use it effectively.

Each serving provides 4,000 IU of Quali®-D Vitamin D3, a patented form manufactured under tightly controlled quality and purity standards. Quali®-D is the most bioavailable form of vitamin D, clinically proven to effectively raise and maintain vitamin D status, support immune function, muscle health, mineral metabolism and bone health.*

But absorption is only part of the story. RYTHM™ pairs D3 with 200 mcg of MenaQ7® Vitamin K2 as MK-7, a clinically researched, patented K2 with high bioavailability and a long circulating half-life, making it particularly suited to once-daily supplementation. K2 activates proteins involved in directing and utilizing calcium appropriately, supporting both bone mineralization and vascular health.*

Finally, 3 mg of boron glycinate supports the wider mineral and vitamin D metabolism environment.

The result is more than a dose of Vitamin D: it’s an intelligently designed D3 + K2 + boron system built around absorption, utilization and long-term bone, muscle and vascular health.*
