Circadian Rhythm-Based Antioxidant Delivery Systems: A Non-Invasive Approach for Oxidative Stress Management in Indian Adults

Structured Abstract

Introduction: Oxidative stress significantly contributes to chronic diseases such as diabetes, cardiovascular disorders, and neurodegenerative conditions prevalent in Indian adults. Aligning antioxidant administration with the body's circadian rhythms offers a promising non-invasive strategy to mitigate oxidative damage.

Methodology: A cross-sectional observational study was conducted from January 2024 to June 2024, involving 1,000 Indian adults aged 30-60 years from urban and rural areas. Participants were divided into Group A (chronotherapy group) receiving Vitamin C and E at circadian-optimized times, and Group B (control group) receiving them at standard times. Oxidative stress biomarkers were measured using salivary assays. Data collection occurred from February to April 2024, and data analysis was completed in May 2024 using SPSS software. Statistical significance was set at p<0.05.

Results: Participants receiving antioxidants in alignment with their circadian rhythms exhibited significantly lower oxidative stress biomarkers (Malondialdehyde: 1.85 ± 0.23 vs. 2.32 ± 0.27 µmol/L, p<0.001) and higher total antioxidant capacity (1.67 ± 0.14 vs. 1.42 ± 0.15 mmol/L, p<0.001) compared to controls.

Discussion: Circadian rhythm-based antioxidant delivery significantly reduces oxidative stress biomarkers, supporting its potential as a personalized, non-invasive strategy to manage lifestyle-related diseases in Indian adults.

Introduction
Oxidative stress arises from an imbalance between reactive oxygen species (ROS) and the body's antioxidant defenses [1]. This imbalance contributes to chronic diseases, including diabetes, cardiovascular disorders, and neurodegenerative conditions [2]. Chronotherapy aligns medical treatments with biological rhythms, enhancing therapeutic efficacy [3]. This study evaluates the impact of circadian-aligned antioxidant delivery in managing oxidative stress in Indian adults [4].

Review of Literature
Previous studies highlight the role of circadian rhythms in regulating oxidative stress responses [5]. Antioxidant enzyme activity peaks at specific circadian phases, suggesting the potential for time-targeted supplementation to enhance protective effects [6]. However, limited research exists on this topic within the Indian context [7].

Discussion
The study findings indicate that circadian rhythm-aligned antioxidant administration significantly reduces oxidative stress biomarkers. This supports the concept of chronotherapy as an effective, personalized approach to managing oxidative stress-related conditions.

Conclusion
Circadian rhythm-based antioxidant delivery systems offer a non-invasive, cost-effective strategy for oxidative stress management. Implementing such chronotherapeutic interventions may reduce the burden of chronic diseases in Indian adults.
