Strengthen Your Immune System

As we age, our immune system naturally weakens (immunosenescence), making seniors more vulnerable to infections. Your OTC benefit covers several evidence-based products that support immune function.

Proven Immune Supplements

Hygiene Products

Probiotics

Evidence-Based: Vitamin D, Vitamin C, and Zinc are the only three supplements with strong clinical evidence for immune support in older adults. Other supplements may help but have less research backing.
