Suplements for colds and flu


For dealing with colds and flu, recommends several supplements based on clinical literature and his consultations with medical experts. Here are the primary recommendations:

  1. Zinc: Supplementing with zinc can enhance recovery from colds significantly. A dosage of 90-100 mg per day can expedite recovery threefold. Zinc is generally safe and cost-effective, but always consult with a physician before starting high-dose supplementation, especially for specific populations such as children, the elderly, and pregnant women 1.

  2. Vitamin D: Regular intake of 1000-2000 IU of vitamin D can support the immune system, potentially preventing respiratory tract infections. It plays various roles in bodily functions and ensures adequate levels may reduce the risk of respiratory infections. However, excessive vitamin D intake should be avoided 2.

  3. N-Acetylcysteine (NAC): NAC has been shown to prevent influenza infections effectively; about 25% of users in a study contracted the flu compared to 79% in the control group. It functions by boosting glutathione levels, which is beneficial for immune health. The dosage varies, but around 1200 mg per day, split into two doses, is common for prevention 3.
