10 Must-Have Health Supplements to Boost Your Immune System Naturally

A powerful immune system is required for protection against infections, viruses, and health threats. Several health supplements offer supplementary immune system protection, together with standard dietary practices, physical movement, and adequate sleep.

Modern environmental pollutants, stress, and poor diets cause the body to lack crucial nutrients required for peak immune system performance. Supplements designed to boost immunity functions serve as an effective solution.

The following guide reveals 10 must-have health supplements that can build up your immune system. Supplements contain fundamental vitamins, minerals, and antioxidants to help the body battle infections and sustain overall wellness.

1. Vitamin C – The Ultimate Immunity Booster
