The longevity and biohacking supplement market has exploded in recent years, with consumers increasingly seeking science-backed solutions to optimize their health, energy, and cognitive performance. Among the newer entrants making waves in this space is Zenos Health, a brand that positions itself at the intersection of cutting-edge longevity science and accessible wellness.
But with so many supplement companies making bold claims, how does Zenos Health actually stack up? This comprehensive review examines the brand's origins, product formulations, ingredient quality, and whether the science supports the promises being made.
What Is Zenos Health?
Zenos Health is a biohacking and longevity-focused supplement company founded in 2024 by brothers Mazen and Marwan Karnaby. The brand officially launched in May 2025 with a mission to make advanced longevity strategies accessible to everyday consumers, not just elite biohackers with unlimited budgets.
Unlike many supplement companies that offer crowded multivitamin blends with dozens of ingredients at sub-therapeutic doses, Zenos Health takes a different approach. The brand offers purpose-built formulas that target specific physiological systems — cognitive function, cellular health, gut microbiome balance, mood regulation, and physical performance.
The company manufactures its products in the United States at cGMP and NSF-certified facilities, adhering to strict quality control standards. All products are third-party tested by Eurofin, a global leader in laboratory testing, with Certificates of Analysis available for consumers who want to verify potency and purity.
The Founders: A Personal Mission Born From Health Crisis
Understanding the origins of Zenos Health requires knowing the story of its founders, particularly CEO Mazen Karnaby. In 2023, Mazen — a BS Pharmacy graduate — received a melanoma diagnosis that fundamentally altered his perspective on health and aging.
Rather than accepting this diagnosis as an isolated medical event, Mazen dove deep into the world of biohacking, longevity science, and cellular health optimization. He became convinced that the mainstream wellness industry was failing consumers with misinformation, weak science, and overhyped products that prioritized profit over efficacy.
His brother Marwan, a pharmacy professional since 1994 with extensive experience in formulation and therapeutic development, joined the mission. Together, they set out to create a supplement brand that would deliver clinically meaningful doses of research-backed ingredients rather than proprietary blends hiding behind vague labeling.
The founders have been vocal about their frustration with the supplement industry status quo. Mazen has described the wellness space as one that “thrives on misinformation” where “big brands profit from keeping people in the dark” with under-dosed formulas and surface-level solutions. Whether one agrees with this assessment or not, it provides context for understanding Zenos Health's positioning and formulation philosophy.
Complete Product Line Overview
Zenos Health offers a targeted lineup of supplements, each designed to address specific aspects of health optimization. Here is a breakdown of their current product offerings:
BrainZen — Cognitive Support Formula ($119.99)
BrainZen is the brand's flagship cognitive support supplement, designed to address both daily mental performance and long-term brain health. The formulation centers on Nicotinamide Riboside, a precursor to NAD+ (nicotinamide adenine dinucleotide), a molecule essential for cellular energy production and neurological function.
The product contains eight clinically supported ingredients targeting multiple pathways of cognitive enhancement including memory, focus, mental clarity, and neuroprotection. Unlike many nootropic supplements that rely on caffeine or other stimulants for immediate but temporary effects, BrainZen is stimulant-free, making it suitable for those sensitive to caffeine or those who want to avoid energy crashes.
Key mechanisms the formula targets include supporting NAD+ production for brain energy, protecting against oxidative stress and blue light damage, enhancing neurotransmission, and supporting healthy blood flow to the brain. The brand positions this as a drug-free approach to cognitive optimization suitable for long-term daily use.
CellZen — Cellular Health and Longevity ($172.49)
CellZen represents the brand's most sophisticated formulation, targeting cellular health at the foundational level. This is the flagship longevity product, designed to support autophagy, mitochondrial function, and protection against cellular aging.
The formula features several notable ingredients including Urolithin A for autophagy support and clearance of senescent cells, Spermidine for cellular renewal, N-Acetyl Cysteine (NAC) as a glutathione precursor, Fisetin as a senolytic compound, and Palmitoylethanolamide (PEA) and Oleoylethanolamide (OEA) for inflammatory response support.
CellZen also incorporates several branded, trademarked ingredients with their own clinical research backing including GlucoVantage at 300mg, ReserveNature (premium resveratrol) at 300mg, MonaJuventa Nu, and MitoPrime.
The dosing protocol calls for five capsules daily with food, with the brand noting that consistent use for two to three weeks helps unlock visible benefits. Each bottle contains 150 capsules for a 30-day supply.
GutZen — Microbiome Support
GutZen addresses gut health through a comprehensive three-in-one approach combining prebiotics, probiotics, and postbiotics. The formula includes Akkermansia (a next-generation probiotic strain gaining significant research attention) and Butyrate (a short-chain fatty acid critical for gut lining health).
The brand positions the gut as “your second brain,” acknowledging the growing scientific understanding of the gut-brain axis and its influence on everything from mood to immunity to cognitive function. The orange-flavored powder format is designed for easy mixing and absorption.
VZen — Female Microbiome Optimization ($98.24)
VZen is specifically formulated for women's health, targeting vaginal flora balance, urinary tract health, and digestive comfort. Key ingredients include Tropica probiotics and PraCran cranberry extract.

This represents a growing category in women's health supplements that goes beyond generic multivitamins to address female-specific physiological needs.
MoodZen — Emotional Balance Support ($134.99)
MoodZen targets mood regulation, stress response, and emotional balance through a combination of several researched ingredients. The formula includes magnesium (one of the most well-researched minerals for mood and relaxation), Hedera helix, phospholipids including Phosphatidylserine, Nicotinamide Riboside Chloride for NAD+ support, Cognizin (a patented, highly bioavailable form of citicoline), ReserveNature (premium resveratrol), and CogniUp (a patented blend of Huperzia serrata, Convolvulus pluricaulis, and Celastrus paniculatus extracts).
The product is designed to promote a sense of well-being, provide natural stress relief, enhance mental clarity, and help regulate cortisol levels. This represents a more sophisticated approach to mood support than simple single-ingredient supplements.
MuscleZen — Strength and Recovery ($176.99)
MuscleZen targets physical performance through natural compounds that support muscle growth pathways without hormones. Key ingredients include Epicatechin (a flavanol found in dark chocolate that research suggests may support muscle growth) and Apigenin (a flavonoid that may support nitric oxide production and testosterone levels naturally).
The formula is positioned for both active athletes seeking performance enhancement and older adults looking to maintain muscle mass and prevent age-related sarcopenia.
BurnZen — Metabolic Support ($119.99)
BurnZen addresses metabolism and appetite regulation, though specific ingredient details are less prominently featured in available information. The product falls within the cellular health category alongside the longevity-focused formulations.
BeautyZen — Skin and Anti-Aging ($127.49)
BeautyZen targets skin health and aging from the inside out, featuring keratin and other compounds designed to support skin elasticity, reduce visible signs of aging, and promote healthy hair and nails.
CreaZen — Creatine Gummies
CreaZen offers creatine monohydrate in a convenient gummy format, delivering 5000mg per serving using CreaPure, a branded form of creatine known for its purity. The mango and blueberry flavored gummies provide an alternative to traditional creatine powders while supporting ATP production, strength, muscle growth, and prevention of age-related muscle loss.
UriZen — Urinary and Kidney Health
UriZen supports urinary tract and kidney function with a clean, clinically backed formula focused on hydration, balance, and protection.
The Zenos Tech Platform: Data-Driven Health Optimization
One of the more distinctive aspects of Zenos Health is its integrated technology platform, Zenos Tech. This is not a common offering among supplement companies and represents an attempt to differentiate beyond just product formulation.
Zenos Tech is an AI-powered health dashboard that subscribers gain access to, designed to connect the dots between supplement intake and measurable health outcomes. The platform integrates with over 50 wearables and lab providers including major names like Labcorp, Quest, Dutch, and Genova.
Users can track HRV (heart rate variability), glucose levels, sleep quality, mood, energy, and recovery metrics, all in one dashboard. The platform provides real-time insights, personalized optimization recommendations, and longitudinal analysis to help users understand how their supplement regimen is actually affecting their biomarkers.
This data-driven approach aligns with the quantified self movement and addresses a common criticism of supplements — that consumers have no way to verify whether products are actually working for them. By connecting supplement use with measurable outcomes, Zenos Health attempts to provide that feedback loop.
The technology is built on Heads Up data infrastructure and is designed for “premium, concierge-style care,” helping practitioners and health coaches create truly personalized protocols based on real-world data rather than just lab visits.
Understanding the Key Ingredients
Several ingredients appear across multiple Zenos Health products, reflecting the brand's emphasis on certain mechanisms of action.
Nicotinamide Riboside and NAD+ Support
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells that plays a critical role in energy metabolism, DNA repair, and cellular signaling. NAD+ levels naturally decline with age, and this decline has been associated with various aspects of aging and age-related diseases.
Nicotinamide Riboside (NR) is a form of vitamin B3 that serves as a precursor to NAD+, meaning the body can convert it into NAD+ through metabolic pathways. Research has shown that NR supplementation can effectively raise NAD+ levels in humans.
According to WebMD, Nicotinamide Riboside Chloride is “possibly safe when used in doses up to 300mg daily,” based on available research. Studies have demonstrated dose-dependent relationships between NR intake and plasma NAD+ levels, with higher doses maintaining elevated NAD+ for longer periods.
However, it is important to note that while NR can raise NAD+ levels, the clinical benefits of this elevation for healthy individuals are still being researched. Most studies showing benefits have been in specific populations or animal models, and the translation to general anti-aging benefits in healthy humans remains an active area of investigation.
Urolithin A
Urolithin A is a metabolite produced when gut bacteria process ellagitannins (compounds found in pomegranates, berries, and nuts). Not everyone produces Urolithin A efficiently from dietary sources due to variations in gut microbiome composition, which is why direct supplementation has gained interest.
Research suggests Urolithin A may support autophagy (the cellular cleanup process), mitochondrial function, and the clearance of senescent cells — often called “zombie cells” that accumulate with age and contribute to inflammation and tissue dysfunction.
Branded Ingredients
Zenos Health uses several trademarked, branded ingredients with their own research backing. These include Cognizin (a patented form of citicoline that has been studied for cognitive support and crosses the blood-brain barrier effectively), GlucoVantage (a dihydroberberine compound with research supporting metabolic health), ReserveNature (a premium resveratrol with standardized purity), CreaPure (a highly pure form of creatine monohydrate from Germany), and CogniUp (a patented combination of traditional botanical extracts).
The use of branded ingredients is generally a positive sign, as these typically come with quality guarantees, standardized potencies, and often have their own clinical studies supporting efficacy.
Manufacturing and Quality Standards
Zenos Health emphasizes several quality control measures. Products are manufactured in the USA at facilities holding both cGMP (Current Good Manufacturing Practice) certification and NSF certification. All products undergo third-party testing by Eurofin with Certificates of Analysis available. Formulations are Non-GMO, gluten-free, dairy-free, with no fillers or artificial additives. Products are packaged in environmentally friendly, refillable bottles.
These certifications and practices represent industry best practices, though consumers should note that they verify manufacturing quality and label accuracy rather than clinical efficacy of the final products.
The Zenos Health Summit: Building Community and Credibility
In October 2025, Zenos Health hosted its inaugural Zenos Health Summit in Riyadh, Saudi Arabia — described as the Middle East's first comprehensive gathering focused on longevity science, biohacking, and integrative medicine. The three-day event brought together over 1,000 participants and featured notable speakers including Dr. Mark Hyman (functional medicine physician), Gary Brecka (human biologist and longevity expert), and Dr. Amy Shah (gut-brain science specialist).
The summit represented a significant brand-building effort, positioning Zenos Health not just as a supplement company but as a hub for the broader longevity and biohacking community. The event aligned with Saudi Arabia's Vision 2030 health innovation initiative, suggesting strategic positioning in emerging markets for wellness and longevity.
Premium ticket tiers ranged from $3,500 for daytime-only access to $5,997 for full VIP experiences, indicating the high-value positioning of the brand and its community.
Pricing and Value Analysis
Zenos Health products fall in the premium tier of the supplement market. Individual products range from approximately $98 to $177, with most falling in the $120 to $135 range.
For context, BrainZen at $119.99 competes with other premium nootropic formulations, CellZen at $172.49 is positioned against other longevity-focused cellular health products that often cost $100 or more for single-ingredient formulations, and the pricing reflects the use of branded ingredients, third-party testing, and domestic manufacturing.
Subscription options are available, offering cost savings while also providing access to the Zenos Tech platform. Free shipping kicks in at orders over $140.
Whether this pricing represents good value depends on the consumer's priorities. Those seeking the cheapest option will find more affordable alternatives, but those prioritizing ingredient quality, dosing transparency, and integrated health tracking may find the premium justified.
Potential Concerns and Considerations
As with any supplement purchase, consumers should consider several factors.
First, regarding regulatory status, like all dietary supplements, Zenos Health products have not been evaluated by the FDA for treating, curing, or preventing any disease. The brand appropriately includes required disclaimers on all products.
Second, while many individual ingredients have research supporting their mechanisms of action, the specific Zenos Health formulations as complete products have not undergone published clinical trials. This is common in the supplement industry but worth noting.
Third, theoretical safety concerns exist with NAD+ boosters. Some researchers have raised theoretical concerns that compounds that raise NAD+ levels could potentially support the growth of existing cancers, though this remains an area of ongoing research rather than established risk. Those with cancer or cancer history should consult healthcare providers before using NAD+ boosting supplements.
Fourth, longevity supplements work best as part of a comprehensive lifestyle approach including proper nutrition, exercise, sleep, and stress management. No supplement can compensate for poor lifestyle choices.
Fifth, individuals with medical conditions or those taking medications should consult healthcare providers before starting any new supplement regimen, particularly with compounds that affect cellular metabolism.
Who Is Zenos Health Best Suited For?
Based on the product lineup, pricing, and brand positioning, Zenos Health appears best suited for health-conscious individuals interested in longevity and biohacking, those who value ingredient transparency and branded compounds over proprietary blends, consumers willing to invest in premium supplements as part of a comprehensive health strategy, individuals interested in tracking their health data alongside supplement use, those seeking targeted solutions rather than generic multivitamins, and men and women in their 30s through 60s focused on optimizing healthspan.
The brand may be less ideal for budget-conscious consumers seeking the lowest-cost options, those looking for quick-fix solutions rather than long-term optimization, individuals who prefer single-ingredient supplements over comprehensive formulas, and anyone not interested in the data-tracking and technology aspects.
The Bottom Line: Is Zenos Health Worth It?
Zenos Health represents a thoughtful entry into the longevity supplement space, distinguished by several factors: founder credibility with pharmaceutical backgrounds, transparent use of branded ingredients with their own research backing, integration of health tracking technology, emphasis on targeted formulations rather than everything-in-one approaches, and quality manufacturing standards with third-party verification.
The brand's origin story — born from a founder's personal health crisis and subsequent deep dive into longevity science — provides authentic positioning in a market often driven by pure commercial interest.
However, consumers should approach with realistic expectations. Longevity science is still evolving, and many promising compounds have research supporting mechanisms of action without definitive proof of long-term benefits in healthy humans. Supplements are tools that work best within a comprehensive approach to health, not magic bullets.
For those willing to invest in premium supplements and interested in the quantified approach to health optimization that Zenos Health offers, the brand provides a credible option. The integration of the Zenos Tech platform addresses one of the fundamental challenges in supplement use — knowing whether products are actually making a difference for your individual physiology.
For those new to the longevity and biohacking space, starting with a single product relevant to your primary health goal (cognitive support with BrainZen, cellular health with CellZen, or gut health with GutZen) and tracking outcomes over several months would be a reasonable approach before committing to multiple products.
Ultimately, Zenos Health positions itself as more than just a supplement company — it is attempting to build a movement around science-backed longevity optimization. Whether the brand delivers on that ambitious vision will become clearer as more consumers use the products over time and share their experiences.
