This review suggests keeping selenium levels adequate may matter for muscle health in later life.
Older people with low selenium levels tend to have weaker grip and less muscle, and the lower the level, the worse it looks. This comes from a review pulling together population studies, one clinical study and animal experiments. For anyone worried about staying strong with age, it points to a trace mineral found in Brazil nuts, fish and eggs. Only animals have been given selenium in experiments so far, so no human trial shows supplements protect muscle.
