Multivitamins Slow Biological Aging: Study
A new two-year clinical study in *Nature Medicine* provides evidence that daily multivitamin supplementation can slow biological aging (as measured by epigenetic clocks) by about four months in older adults. This peer-reviewed data validates offering evidence-based supplement tracking and education modules within health platforms.
The study, published in *Nature Medicine*, analyzed data from the COcoa Supplement and Multivitamin Outcomes Study (COSMOS). Researchers at Mass General Brigham and Augusta University examined how daily multivitamin use affects biological aging. The trial included 958 healthy participants around age 70. Biological age reflects the body's condition, differing from chronological age. Epigenetic clocks, which measure DNA methylation patterns, estimate biological age. These clocks analyze modifications to DNA that accumulate and affect gene function over time. The study found that participants taking a daily multivitamin experienced a slowdown in biological aging, particularly in clocks estimating mortality risk. This slowdown equated to roughly four months over two years. The multivitamin used in the study was Centrum Silver. Interestingly, the effects were more pronounced in individuals exhibiting faster biological aging at the study's outset. Scientists suggest that this may be because such participants had greater nutritional deficits to begin with. The study was funded partly by Mars, the confectionery manufacturer. Epigenetic clocks are considered valuable tools for studying the aging process. An epigenetic clock is an analytical method used as a biomarker of aging to estimate "biological age". Positive epigenetic age acceleration suggests that the underlying tissue ages faster than expected. The multivitamin supplements market is projected to reach $437.1 billion in 2026 and $773.7 billion by 2036, with a CAGR of 5.9%. The global vitamin supplements market was estimated at USD 59.45 billion in 2025 and is projected to reach USD 106.12 billion by 2033, growing at a CAGR of 7.5% from 2026 to 2033. Multivitamins held the largest market share of 45.1% in 2025. For consumer health startups, effective marketing strategies are crucial. Creating engaging, educational content can attract and retain users. Also, leveraging user feedback and adapting marketing strategies accordingly is essential for continuous improvement. Consider focusing on user-friendly design, prioritizing essential features, and ensuring data protection. Mobile health app developers should adhere to regulations like HIPAA. A multi-channel approach, including SEO, social media, and patient advocates, can help popularize a patient-facing app.
