This study suggests vitamin D and vitamin E may support immune function in older adults.
As we age, our immune system gets sluggish and inflammation creeps up. Looking at nine trials, researchers found that vitamin and mineral supplements modestly improved immune function in older adults. Vitamin D lowered inflammation and raised immune cell activity, while vitamin E had the biggest effect on cell-based defenses. The overall boost was real but small.
