The 15 Best Supplements to Boost Your Immune System Right Now
Zinc plays an important role in the inflammatory response. Without strong zinc, immune cells cannot develop. As expected, a deficiency in this nutrient usually results in an increased risk of disease and infection, including pneumonia. Zinc deficiency is common in older adults. Studies reveal that zinc supplements may protect you from the common cold and can be beneficial even when you are already sick.
Zinc supplements can even protect you from respiratory tract infections and reduce the duration of these infections. Healthy adults can take zinc long term, as long as the daily dose is set the upper limit of 40 mg of elemental zinc. Excessive zinc dose may interfere with copper absorption.
