HIIT cut fat and held muscle in older adults, but the edge was small
In a 6-month trial of more than 120 healthy older adults, high-intensity interval training reduced fat while holding onto muscle, unlike moderate exercise, which shaved a little. The authors say the differences between intensities were small.
Fact-checkCalcium and vitamin D supplements do little to prevent fractures or falls
A review of 69 randomized trials and more than 150,000 people found that for healthy older adults, calcium, vitamin D, or both together did little to prevent fractures or falls.
ExplainerIn a small trial, low-dose creatine improved reaction time in menopausal women
Researchers ran one of the first randomized trials of creatine in women going through menopause. At a modest daily dose, the supplement edged out a placebo on reaction time, brain creatine and cholesterol, though the study was small and lasted only eight weeks.
ExplainerSemaglutide slowed measures of biological aging in a small trial
Researchers reanalyzed a 32-week trial of semaglutide in 84 adults and found the drug slowed several DNA-based clocks of biological aging. The aging analysis was exploratory, and the group studied was specific.
NewsHigher blood vitamin C is linked to more gray matter in older adults
In 2,044 older adults in Japan, those with lower vitamin C in their blood tended to have less gray matter and weaker connections in a key brain network. It is a snapshot, so it cannot show that vitamin C protects the brain.
