What Are Functional Mushrooms and Why They Matter for Aging and Health?

Mushrooms used in longevity research, such as Reishi, Lion’s Mane, and Cordyceps, are natural sources of bioactive compounds that support brain health, immune balance, mitochondrial function, and stress resilience. These effects are primarily driven by molecules like β-glucans, triterpenes, and cordycepin, which act on core aging pathways including inflammation, oxidative stress, and cellular repair.

Although each mushroom has distinct effects, they all help the body manage oxidative stress, modulate inflammation, and preserve cellular integrity; which are three critical functions that decline with age. These shared effects are largely driven by β-1,3-glucans, natural polysaccharides known to support immune balance and enhance resistance to oxidative damage. Research in preclinical models shows that β-glucans can delay cellular aging by reducing senescence markers, protecting tissues, and promoting stress resilience.

Together, these mushrooms also act as adaptogens, natural compounds that help the body restore balance and maintain stability under physical, emotional, or metabolic stress. Adaptogens work by modulating stress response systems like the HPA axis and immune signaling pathways, improving how the body adapts to external challenges without overstimulation or suppression. This mechanism is particularly relevant for aging, where internal resilience tends to decline. Mushrooms qualify as adaptogens because they contain β-glucans and other bioactive molecules that support stress regulation, energy homeostasis, and immune modulation.

The longevity benefits of mushrooms come from three specific types used in NOVOS Bars, each selected for its unique composition of active compounds:

• Reishi (Ganoderma lucidum) – Rich in triterpenes and β-glucans that support immune regulation, inflammation control, and cellular protection.
• Lion’s Mane (Hericium erinaceus) – Contains hericenones and erinacines, which stimulate nerve growth factor (NGF) and promote cognitive function and neuroregeneration.
• Cordyceps (Cordyceps militaris) – Provides cordycepin and adenosine analogs that enhance mitochondrial function, oxygen utilization, and physical endurance.

These mushrooms are rarely consumed in typical diets and must be carefully standardized to deliver meaningful levels of their active compounds. The extracts in NOVOS Bars are specifically formulated to match doses used in clinical research.

Each NOVOS Bar delivers a research-aligned dose of functional mushrooms:
– 200 mg Reishi extract (35% β-glucans)
– 200 mg Lion’s Mane extract (≥25% β-glucans)
– 200 mg Cordyceps extract (25% β-glucans)

Combined, these provide approximately 170 mg of total β-glucans per bar—a scientifically grounded amount shown in clinical studies to support immune health, cognitive function, and mitochondrial performance.

In preclinical studies, β-glucans have been shown to extend lifespan in mice by reducing cellular senescence, enhancing antioxidant defences, and preserving tissue function. Additional findings suggest that triterpenes found in Reishi, such as ganoderic acid A, may further support longevity by modulating senescence pathways at the molecular level [R].

Potential Health Benefits of Mushrooms

Modern clinical research confirms that the mushrooms used in the NOVOS Bar, Reishi, Lion’s Mane, and Cordyceps, offer meaningful, measurable effects in humans. 

These mechanisms are all supported by randomized controlled trials (RCTs) in humans. These are trials with a placebo group (which controls for placebo effects) and in which participants are randomly allocated to the experimental or control groups (which removes allocation bias). RCTs are considered the gold standard in clinical human research.

• Cognitive Function and Brain Health :In a placebo-controlled trial with older adults diagnosed with mild cognitive impairment, Lion’s Mane significantly improved memory, focus, and orientation after 16 weeks of supplementation. The effects declined after stopping the supplement, suggesting the importance of continuous intake [R].
• Energy, Endurance and Mitochondrial Function : Cordyceps supplementation increased VO₂max and reduced fatigue in healthy adults after just 3 weeks. These improvements reflect better oxygen utilization and mitochondrial efficiency, without overstimulating the body [R].
• Immune Balance and Inflammation : Reishi improved immune function in clinical trials by increasing natural killer (NK) cell activity and modulating T-cell responses. These effects support better immune coordination, especially in individuals under chronic stress or with weakened defences [R].
• Systemic Resilience and Stress Adaptation: All three mushrooms are recognized as adaptogens, natural agents that help the body adapt to physical and mental stress. Cordyceps, in particular, has been shown to enhance endurance and recovery, while Reishi supports homeostasis under immune and inflammatory stress [R].

The Role of Mushrooms in Aging and Longevity

Mushrooms and Cognitive Function, Lifespan Extension, and Cellular Health

Before looking at each mushroom individually, it’s important to highlight one shared mechanism behind their impact: β-glucans. These are natural polysaccharides found in the cell walls of fungi, including Reishi, Lion’s Mane, and Cordyceps. They are best known for supporting immune balance and defending against oxidative stress, but their role in aging goes much deeper [R].

In a landmark 2019 study, researchers gave β-1,3-glucans to short-lived fish (Nothobranchius guentheri), a species commonly used in aging research because of its rapid accumulation of cellular damage. The fish that received β-glucans not only lived longer, but their tissues also showed slower biological aging. Two key markers were tracked:

• Lipofuscin, a pigment that accumulates as waste in aging cells
  
• SA-β-Gal, a well-known marker of cellular senescence

The figure below shows tissue sections from the study. Panel C displays caudal fin samples from both groups, control (top) and β-glucan-treated (bottom),  at weeks 38, 42, and 46. With age, the control fish show increased staining for SA-β-Gal, indicating more senescent cells. In contrast, the treated group shows much lower levels at the same timepoints. Panel D quantifies this effect, confirming a statistically significant reduction in senescence with β-glucan intake.

Figure 1 – β-glucans delay cellular aging. Panel C: histological sections of fish fin tissue. Top row: control group shows increased senescence with age. Bottom row: β-glucan group maintains lower SA-β-Gal staining. Panel D: bar graph quantifies the difference across time points.

These findings show that β-glucans don’t just support immunity, they slow cellular aging itself. They reduce senescence, protect tissue structure, and improve resilience to oxidative damage. Since all three mushrooms in the NOVOS Bar are standardized extracts rich in β-glucans, and each bar delivers approximately 170 mg of total β-glucans, this mechanism directly supports the inclusion of Reishi, Lion’s Mane and Cordyceps as synergistic longevity ingredients.

Reishi

Among the three mushrooms used in the NOVOS Bar, Reishi stands out for its strong immunomodulatory properties. A Cochrane Systematic Review, one of the highest standards in medical research, examined the effects of Ganoderma lucidum in over 400 patients across five randomized controlled trials [R].

The results showed that Reishi significantly enhanced immune function, particularly by increasing Natural Killer (NK) cell activity and improving T-cell response. These effects suggest a more coordinated and efficient immune system,  something that typically declines with age and contributes to chronic low-grade inflammation, also known as inflammaging.

Beyond immune enhancement, Reishi was also associated with better immune regulation, meaning it helped modulate overactive inflammatory responses without suppressing essential defences. This dual action, stimulation where needed, calming where necessary, is especially important for healthy aging, where immune balance is key to maintaining tissue integrity [R].

While the doses in these studies ranged from 1.4 to 5.4 grams per day, the 200 mg used in the NOVOS Bar delivers a concentrated extract standardized to 35% β-glucans, contributing to this same mechanism in a synergistic daily format.

Lion’s Mane

Lion’s Mane is renowned for its neuroprotective properties, particularly in supporting cognitive function during aging. A pivotal double-blind, placebo-controlled clinical trial conducted by Mori et al. (2009) evaluated the effects of Hericium erinaceus on 30 adults aged 50 to 80 years diagnosed with mild cognitive impairment (MCI). Participants received 3 grams per day of Lion’s Mane extract over a 16-week period [R].

The study reported significant improvements in cognitive function, as measured by the Mini-Mental State Examination (MMSE), at weeks 8, 12, and 16 compared to the placebo group. Notably, these cognitive benefits diminished four weeks after cessation of the supplementation, indicating the importance of continuous intake for sustained effects. As shown in the figure below, cognitive scores rose steadily in the Lion’s Mane group, while the placebo group showed no meaningful changes.

Figure 2: Cognitive improvement with Lion’s Mane. Participants with mild cognitive impairment took 3 g/day of Hericium erinaceus for 16 weeks. Cognitive scores increased significantly at weeks 8, 12, and 16. After stopping the supplement (+4 weeks), scores declined again, showing that continuous intake is important for lasting benefits.

While the dosage used in the study was higher than the 200 mg of Lion’s Mane extract found in each NOVOS Bar, the extract in our formulation is standardized to contain no less than 25% β-glucans. This concentrated form, combined with other synergistic ingredients, contributes to a comprehensive approach to support cognitive health and resilience against age-related decline.

Cordyceps

Cordyceps is known for its adaptogenic properties, helping the body respond more effectively to stress, especially when it comes to energy production. In a placebo-controlled clinical trial, healthy adults were given 1.5 grams per day of Cordyceps militaris extract for 3 weeks. The aim was to test changes in VO₂max (a measure of maximum oxygen capacity), endurance, and overall fatigue [R].

The results were clear: VO₂max increased significantly in the Cordyceps group compared to placebo. Participants also showed improvements in oxygen utilization and time to exhaustion, a direct indication that their mitochondria were working more efficiently under physical stress. These changes are especially important during aging, when mitochondrial function tends to decline, reducing energy levels, physical capacity, and metabolic resilience.

Are Mushrooms Good for Anti-Aging?

Mushrooms meet many of the criteria for effective anti-aging compounds:

• Enhance Cognitive Health: Lion’s Mane stimulates nerve growth factor (NGF) and improves memory and focus in older adults.

• Improve Mitochondrial Function: Cordyceps increases VO₂max and oxygen utilization, supporting energy production and physical endurance.

• Regulate Immune and Inflammatory Pathways: Reishi modulates inflammatory cytokines and enhances immune coordination, helping to control chronic low-grade inflammation.

• Extend Lifespan in Preclinical Studies: β-glucans from mushrooms delayed cellular aging and reduced senescence markers in animal models.

• Target Multiple Aging Mechanisms: Mushroom compounds act on oxidative stress, mitochondrial decline, inflammation, and cellular senescence, all key drivers of age-related decline.

Mushroom Dosage and Safety: How Much Is Safe for Longevity?

Each NOVOS Bar delivers 600 mg of organic mushroom extracts: 200 mg each of Reishi (35% β-glucans), Lion’s Mane (≥25% β-glucans), and Cordyceps (25% β-glucans). This provides approximately 170 mg of total β-glucans per serving, an amount shown to support immune coordination, cognitive function, and cellular resilience.

For those seeking more pronounced effects, two bars per day approach the β-glucan intake used in clinical trials demonstrating improvements in VO₂max, memory, and immune balance.

Mushroom extracts at these levels are well-tolerated and supported by a long history of safe use in both traditional medicine and modern clinical research. This makes NOVOS Bars a practical, science-backed way to incorporate mushroom compounds into a longevity-focused routine.

→ 1 bar/day supports foundational benefits for brain, immune, and cellular health

→ 2 bars/day aligns with β-glucan levels studied for broader effects in humans
