Vitamin D 用于 Immune Aging (Immunosenescence)
BResearch suggests vitamin D supplementation in elderly populations may help improve immune markers and vaccine response. Deficiency is highly prevalent in older adults and is associated with impaired immune function and increased infection susceptibility.
