Yes, thanks to you and others I take Vit D, K, Zinc, Quercetin, NAC, Grape seed extract and Turmeric daily.
Quercetin is a wonderful antioxidant … on many different levels. Truly love it.
A good list of items to be taking to strengthen immune system, however, I notice that Vitamin C is missing. I suggest you look for Dr. Robert Cathcart on Google, and his treatment of many serious illnesses with high dose Vitamin C to the point of bowel tolerance (when diarrhea starts, than reduce the amount of C you are taking a bit). Cathcart believes we should all be getting about 4 grams a day of C, food or supplements. I have been taking about 6 or 7 grams a day, divided doses, for over 50 years for various respiratory allergies.
Lat Dec. 2021 I attended a restaurant feast with 12 vaccinated people. Ten days later my nose began to run like a water faucet (new experience), and I began to take a gram of C every hour or two. Total about 14 grams in 24 hours. Woke in the morning with nose completely clear, no additional symptoms. I wonder if I successfully fought off an attack of Covid as it tends to target cells in the nose first.
Many years ago while volunteering at the MASH tent at a large wilderness event, a woman had been stung in the neck by 3 yellow jackets. She was swollen and choking badly, so I crushed 10 grams of Vitamin C in a large glass of water. She drank it and in 20 minutes, her choking had stopped, and swelling of her eyes had diminished allowing her to see again. Over 8 hours I gave her a total of 50 grams of C and she had no bowel symptems of diarrhea. She hiked out the next day for 3 miles.
A study of 240 people in Turkey proved the Zelenko 3 part formula of HCQ, zinc, and Azithromycin, plus 1000 IU of Vitamin D, and using half the group with 24 grams of Intravenous Vitamin C, reduced hospitalization by as much as 3 weeks. [Far more effective than Fauci’s darling Remdesivir.] The only death was to a 70 year old woman with cancer and gross deficiency in Vitamin D. A far better death figure than for other studies of hospitalized Covid patients with comorbidities. Dr. Zelenko subsequently suggested Quercetin for those unable to get HCQ or Ivermectin. He also recommended using Doxycycline rather than Azithromycin as a safer antibiotic for lung protection.
