Caring for the mind is part of living better for longer. A study published in Nutrients provides new data on the combination of vitamin D3 and DHA, an omega-3, in older adults with mild cognitive impairment.
For twelve months, researchers followed 360 participants, divided into four groups: vitamin D3, DHA, both nutrients or placebo. The doses were 800 IU daily of vitamin D3 and one gram daily of DHA. 355 people completed the study. The design was randomized, double-blind, and placebo-controlled.
The combination achieved better results in various cognitive tests than each nutrient separately. Five blood markers related to inflammation and pyroptosis, a form of inflammatory cell death, also decreased. The analysis suggested that the reduction of the GSDMD protein could play a role in the observed improvements.
Two nutrients with different functions
DHA is part of cell membranes and is present in the brain and the retina. It is one of the main omega-3s studied, along with EPA and ALA. Although they belong to the same family, they are different molecules: one gram of fish oil is not equivalent to one gram of DHA. That is why knowing the amount of each fatty acid helps interpret both a label and research.
Vitamin D contributes to the absorption of calcium and participates in muscular and immune functions. The body can produce it through sun exposure and obtain it from food and supplements. Its role goes beyond bone health, but every possible benefit requires evidence.
Brain health needs a comprehensive strategy
The accumulated evidence on omega-3 and cognition presents diverse results. Some studies in people with mild cognitive impairment have found improvements in abilities; others, conducted in healthy adults or people with Alzheimer's, have not shown comparable benefits. The context of each study matters as much as its headline.
To care for cognitive health, the National Institute on Aging highlights a balanced diet, physical activity, mental stimulation, and social relationships. It also recommends monitoring blood pressure, checking the effects of medications, and getting enough sleep. These are actions that can be integrated into life: walking, learning something new, spending time with other people, and keeping up with health check-ups.
At Longévitas, we understand longevity from that perspective: understandable science, sustainable habits, and attention to individual needs. Supplementation can be part of that care when indicated, accompanied by professional guidance. Translating science into useful decisions requires assessing who was studied, what was measured, and for how long. This way, we can incorporate new knowledge thoughtfully and build a routine that supports our health throughout the years.
