Scientists have compared 17,000 patient outcomes to their genes, and it appears that COVID attacks the body’s ability to maintain low blood pressure. A failure to regulate bradykinin, a protein, is specifically harmful. The blood-brain barrier fails, causing mental failure. The lungs produce a water-absorbing chemical that swells (somewhat like Jello), preventing gas from being exchanged.
Poor regulation of bradykinin is a common cause of high blood pressure, and existing drugs can be used to help COVID-19 patients. But Vitamin D is also helpful, as I promoted back in April. The report states that 20% of all Americans have a vitamin D deficiency. See your doctor or functional medicine specialist for recommendations on supplementation.
