In contemporary anti-aging nutrition research, Coenzyme Q10 (CoQ10) and ginsenosides have emerged as two highly notable active components, becoming research hotspots due to their remarkable antioxidant properties and energy metabolism regulation capabilities. However, both components face technical challenges such as poor water solubility, low in vivo stability, and limited bioavailability. Through innovative research and development, Natural Field has successfully created a CoQ10-ginsenoside co-loaded liposome delivery system, validating its significant anti-aging effects in experiments utilizing two distinct aging models.
Diverging from commonly used drug-induced or genetically modified models, this study specifically utilized a natural aging mouse model aged 18-24 months. This selection was based on important scientific rationale: the natural aging model can more accurately simulate the progressive and systemic characteristics of human aging. These aged mice spontaneously exhibit typical aging manifestations, including multi-organ functional decline and chronic low-grade inflammation, which are highly consistent with the human aging process. This approach significantly enhances the physiological relevance and predictive value of the experimental results.
The study revealed that intervention with CoQ10-ginsenoside co-loaded liposomes resulted in a remarkable 82% increase in superoxide dismutase (SOD) activity, coupled with a substantial 76% reduction in malondialdehyde (MDA) levels. This research is pioneering in validating the exceptional efficacy of the CoQ10-ginsenoside co-loaded liposome technology within a natural aging model of high physiological relevance. This strategic approach enhances the physiological translatability of the findings, providing breakthrough verification in a model that closely mirrors human aging. It thereby paves a new path for anti-aging nutritional interventions that are more closely aligned with potential real-world applications in aging populations.
Improved Behavioral Status: After the four-week intervention period, mice in the treatment group exhibited more active motor behavior, smoother coat condition, and a significantly improved appetite compared to the untreated aged control group.
Marked Anti-Inflammatory Effects: Serum analysis confirmed significantly lower levels of key inflammatory cytokines (IL-1β, IL-6, and TNF-α) in the intervention group, demonstrating the formulation's capacity to alleviate chronic low-grade inflammation.
Substantially Enhanced Antioxidant Capacity: The most striking outcome was the significant enhancement of the body's antioxidant defenses. Analysis of brain and liver tissues indicated that the co-loaded liposomes effectively reverse oxidative stress imbalance through a dual mechanism: synergistically activating the endogenous antioxidant enzyme system (including SOD and CAT) while concurrently inhibiting the chain reaction of lipid peroxidation.
Evident Tissue-Protective Effects: The group treated with co-loaded liposomes showed significant protective effects on the liver and kidneys, effectively mitigating renal edema and hepatocyte swelling, restoring regular hepatocyte arrangement, and reducing inflammatory infiltration. In the brain, improvements were observed in the morphology of hippocampal neurons, a reduction in cell death, and a trend towards stabilization in the structure of memory-related regions.
To ensure a comprehensive evaluation, the research team concurrently validated the efficacy using a D-galactose-induced senescence model. This well-established experimental model mimics age-related oxidative stress and metabolic dysregulation through chronic D-galactose administration.
The model was established by subjecting C57BL/6 mice to daily subcutaneous injections of D-galactose at a dosage of 300 mg/kg/day for 56 consecutive days. The underlying mechanism involves D-galactose-induced elevation of free radical production within the organism. Consistent with the free radical theory of aging, this accumulation of reactive oxygen species is a pivotal factor in the pathogenesis of age-related degenerative conditions. Key antioxidant enzymes, including Superoxide Dismutase (SOD), Glutathione Peroxidase (GSH-Px), and Catalase (CAT), play an essential role in mitigating free radical formation and associated oxidative damage.
Experimental results demonstrated that the CoQ10-ginsenoside co-loaded liposomes also exhibited potent antioxidant and immunomodulatory functions in this model:
Effectively enhanced hepatic antioxidant enzyme activity and reduced lipid peroxidation levels.
Significantly increased the activity of GSH-Px and SOD, as well as the total antioxidant capacity (T-AOC), in brain tissue.
Reversed the D-galactose-induced decrease in spleen and thymus indices, indicating improved immune function.
Significantly elevated serum immunoglobulin (IgG and IgM) levels.
Compared to conventional CoQ10 and ginsenosides, which often suffer from limited absorption efficiency due to poor water solubility, low chemical stability, and restricted bioavailability, the NF Lipo® co-loaded liposome patent technology enhances efficacy through two core mechanisms:
Multi-Component Affinity Encapsulation Technology: Utilizes affinity interactions between the polyhydroxy groups of ginsenosides, phospholipid headgroups, and active ingredients to form a dense hydrogen-bonding network. This structure reinforces liposomal stability, enabling the stable coexistence of multiple components.
Dual-Mechanism Synergistic Delivery System: Leverages the glycosyl moiety of ginsenosides to guide the co-loaded liposomes to target the SGLT1 glucose transporter in the small intestine, while simultaneously inhibiting P-glycoprotein (P-gp) efflux pump activity. This dual mechanism significantly enhances bioavailability.
The CoQ10-Ginsenoside Co-loaded Liposome technology is suitable for developing various high-end nutritional products, including:
Anti-aging nutritional support formulas
Vitality enhancement and chronic fatigue relief products
Brain health and cognitive function nutraceuticals
Innovative liposomal dosage forms (e.g., oral liquids, softgels)
Professor Li, Chief Scientist at Natural Field, emphasized: "Our dual-validation system, combining both the natural aging model and the chemically-induced aging model, has enabled a comprehensive assessment of the anti-aging efficacy of the co-loaded liposomes. Although this approach requires a longer research cycle, the data obtained possess significantly greater physiological relevance and scientific reliability."
This groundbreaking research underscores a significant advancement in the field of "liposomal technology combined with multi-component synergistic anti-aging," providing a robust scientific foundation for precision nutritional interventions and pioneering new directions for anti-aging product development.
Moving forward, we will continue to explore additional raw material validation protocols based on natural aging models and dual-model systems. Our commitment is to provide global B2B clients with more precise, authentic scientific support and ingredient solutions.
