Recent research questions the effectiveness of common supplements such as vitamin D, omega-3, and glucosamine. According to The Washington Post, these could have adverse effects on the brain during aging.
Recent studies have called into question the effectiveness of certain vitamin supplements, suggesting that they could be harmful to the brain as it ages. According to a report by The Washington Post, vitamin D, omega-3, and glucosamine are being analysed for their possible relationship with cognitive decline in older adults.
The studies show that the brain does not process nutrients in the same way throughout life, which could mean that supplements that were once beneficial may become harmful in later stages. It has been observed that aging leads to a deterioration of the blood-brain barrier and changes in brain metabolism, which alters the response to inflammation and the delivery of nutrients.
An analysis in the British Medical Journal suggests that excess vitamin D could influence the accumulation of beta-amyloid plaques, associated with Alzheimer’s, showing that older adults who consume this supplement exhibit greater cognitive decline than those who do not.
On the other hand, a study in the Journal of Prevention of Alzheimer's Disease correlates omega-3 consumption with a more accelerated cognitive decline in adults aged between 55 and 90 years. These investigations highlight the need to question the safety of supplements in the older population.
Researchers warn that the biological environment of the brain changes with age, implying that the effects of a supplement are not constant throughout life. These findings are crucial for understanding how supplementation can affect the brain health of older individuals.
