Brian King, R. PH. Jeffreys Drug Store 724.745.6480 1 North Central Avenue Canonsburg, PA Please call us at: Jeffreys Drug Store With any questions any time. (724) 745-6480 Q: Vitamin Expert What supplements do you recommend taking this winter to help prevent Covid-19, Flu, and other respiratory diseases? A: For prevention, I would recommend Vitamin D3 (2000 to 5000 units) daily an Zinc (20mg) daily. I would also advise taking an herbal product called Andrographis, which is one of the greatest immune supplements for respiratory infections. It both stimulates the immune system and directly kills viruses and bacteria. If you get exposed to someone with a respiratory infection, or you spend much time in a crowd of people, I would increase your zinc intake to 50 to 100mg a day for 5 days; increase your Andrographis; use an iodine nasal spray immediately after exposure and an antiseptic mouth wash. Andrographis has many health benefits in addition to what I've mentioned above: protects and supports the liver; has anti-tumor properties; soothes and protects the stomach and intestines; and has potent anti-inflammatory properties, which protect joints from arthritic damage.
