In one trial, a daily gram of omega-3 over three years slowed three of four tests that estimate biological age.
Most organs start to lose function in our forties, the authors of this review write. They argue that vitamins, minerals and omega-3 fats deserve attention from midlife on. Many people get too little of them, they say, and older adults often run low on omega-3.
The experts gathered studies without a systematic search. They describe how vitamins and minerals support the cell's power plants, the immune system and the calming of inflammation. As examples they cite trials where chance decided who got what. In one, a daily gram of omega-3 over three years slowed three of four epigenetic clocks. These are tests that estimate biological age from chemical marks on our genes. In another trial, people aged 70 or older with mild memory problems showed slower brain shrinkage on B vitamins.
The authors admit their choice of studies may be biased. They also flag high doses of vitamin E as possibly harmful. In their own words, there is no proof that routine blood tests from around 50 improve health outcomes. The World Health Organization does not recommend such supplements to prevent aging.
Conflict of Interest Disclosure: The authors declare no conflicts, but Nestlé funded two of the group's meetings and the graphics.
