The persistent age-related decline in cognitive and muscular function poses a significant challenge in healthcare. With the ageing population, the financial burden of managing cognitive decline and muscle weakness is expected to escalate. Oxidative stress, characterized by cumulative damage from free radicals, is a principal factor in the health deterioration associated with ageing. Antioxidants found in certain foods can neutralize these radicals, reducing cell damage and slowing the pace of age-related decline. When diets lack antioxidants, many turn to supplements that offer similar or even more excellent protection.
A groundbreaking study led by Professor Koji Fukui from the Shibaura Institute of Technology and Dr. Fukka You from Gifu University has shown promising results. Their research, involving the administration of a blended antioxidant supplement to elderly mice, led to significant improvements in spatial cognition, short-term memory, and muscle strength. Published in the ‘Antioxidants in Health and Diseases’ special issue of the International Journal of Molecular Sciences on February 28, 2024, the findings suggest that long-term intake of these supplements could effectively combat the natural oxidation increases due to ageing.
Memory loss, often linked to debilitating diseases like Alzheimer’s, disproportionately affects older individuals. The study’s results indicate that blended antioxidant supplements could potentially prevent memory loss in humans, like the effects observed in mice. Additionally, sarcopenia—an age-related condition that results in progressive muscle strength loss—significantly impacts mobility and can lead to social isolation and increased risk of cognitive disorders. The improvement in muscle strength observed in mice suggests that antioxidant supplements could also mitigate muscle frailty and sarcopenia in humans.
Professor Fukui highlighted the severity of frailty and sarcopenia as substantial issues and potent risk factors for dementia. The potential of supplements to prevent muscle weakness marks a significant advancement, although the exact mechanisms remain unclear. The marketplace offers a variety of antioxidant supplements, and choosing the right one can be a complex decision for consumers. The positive outcomes from this study support the use of blended antioxidant supplements to prevent age-related health decline. Yet, more research is needed to confirm their effectiveness and safety in humans.
It’s also crucial to understand that different antioxidant blends may vary in their effects on the human body, and their application should ideally be based on clinical evidence. The antioxidant blend used in this study, Twendee X, has a composition similar to the commercially available supplement Oxycut®. Professor Fukui advises that while many antioxidant supplements are available, the effects are more significant when multiple types are taken simultaneously rather than individually. However, determining the appropriate types and quantities can be challenging, as consuming excessive amounts of specific vitamins is possible.
Establishing the correct regimen and selecting the right supplement can be confusing for consumers. Future research into individual differences in the effects of antioxidants can help clarify the optimal dosage and composition of these supplements. Over the long term, optimal use of antioxidant supplements could significantly reduce the health declines associated with ageing.
Professor Fukui envisions a future where multi-supplements are tailored to individual needs, eliminating the concerns about overdosing. This approach would not only ensure safety but also enhance the efficacy of supplements in combating age-related decline. As research progresses, such tailored solutions could become a cornerstone in managing health in older adults, potentially transforming the landscape of age-related healthcare.
