Zinc is crucial for a strong immune response, with deficiencies being common. It's recommended to supplement with 20-50 mg daily, especially during illness. Vitamin D also plays a vital role; aiming for 5,000-10,000 IU daily can help prevent sickness, and higher doses may be beneficial during illness. Prioritizing nutrient-rich foods like wild-caught seafood and grass-fed meats enhances zinc intake.
