Fucoidan linked to longer lifespan in aged mice, preprint finds
A preprint not yet peer reviewed reports that fucoidan, a compound from brown algae, increased median lifespan in aged male mice and reduced frailty and epigenetic age in both sexes. These are animal results and do not show an effect in people.

What the research shows
The preprint, posted on bioRxiv, tested fucoidan, a compound from brown algae, in aged mice. According to the study, the substance activates SIRT6, a protein linked to aging processes. In males, median lifespan increased. In both sexes, the researchers reported reduced frailty and lower epigenetic age, a marker calculated from chemical changes in DNA.
This is a preprint, meaning a work not yet peer reviewed, and its conclusions may change after expert evaluation. Animal results on aging do not show whether a substance works or is safe in people. Mice live under controlled conditions, and their aging does not correspond directly to human aging. The finding is therefore a signal for future research, not guidance for everyday life.
What it means
The finding suggests fucoidan deserves further study on aging, but it is too early to draw conclusions. It is not known whether the effect occurs in people, at what amount, or whether it is safe over the long term. Confirmation by other research groups will be important.
