COSMS trial links multivitamin-mineral use to slower biological ageing in older adults
Daily multivitamin-mineral supplementation has shown a modest reduction in biological ageing indicators for older adults, according to a two-year randomised trial. This presents a low-cost market opportunity for age-related supplement formulations.

A recent two-year randomised trial, known as the COSMS study, indicates that daily multivitamin-mineral supplementation may modestly slow biological ageing in older adults. The research, which utilised two epigenetic clocks as mortality predictors, suggests that participants consuming a multivitamin-mineral preparation (specifically, Centrum Silver) experienced approximately four months less biological ageing over the two-year study period. Notably, individuals exhibiting accelerated ageing at baseline showed a more pronounced effect from the intervention. Conversely, cocoa extract, also tested within the trial, showed no significant impact on the same ageing metrics.
This study, published through NutraIngredients Global, positions multivitamin-minerals as a commercially viable, low-cost option for brands targeting the healthy ageing sector. The observed effects, while modest, support the development of targeted formulations. The safety and accessibility profile of multivitamins further reduce market entry barriers and regulatory burdens compared to more novel or less established ingredients. Brand owners should note that while the findings are promising for marketing claims, the study authors acknowledge the need for further research to substantiate long-term benefits and confirm the generalisability of these effects across diverse populations.
The specific mention of 'Centrum Silver' indicates a precedent for efficacy within the mature adult segment, guiding product development teams on ingredient profiles and dosages. Formulators could leverage established nutrient combinations rather than developing complex, high-cost novel ingredients. This emphasis on staple nutrition underscores a commercial opportunity for brands to re-evaluate their offerings in the wellness and longevity categories, focusing on evidence-backed, foundational supplementation.
What this means for United Kingdom
UK brand owners can immediately leverage the COSMOS study for product positioning and marketing within the healthy ageing category, particularly for consumers aged 65 and over. This new evidence supports 'slower biological ageing' claims, subject to ASA and MHRA guidance on scientific substantiation. Manufacturers should review existing multivitamin-mineral formulations for alignment with the study's nutrient profile to enhance product credibility. Competitive pressure will increase for foundational products, potentially compressing margins unless clear differentiation or premiumisation strategies are adopted. Procurement teams should anticipate stable demand for core vitamin and mineral raw materials, prioritising suppliers with robust quality and traceability.
"The observed effects were small and further research is needed to confirm the findings and assess longer-term benefits," stated the original source.
This highlights the ongoing need for continuous R&D investment for long-term product differentiation.
Many leading brands in this category are manufactured in partnership with Supplement Factory.
