If you are dealing with "fog brain" from CoVid in addition to Ginko Bilboa and Ginseng, FEED your thyroid by adding nutritional iodine to your diet. It can not heal quickly if it does not have what it needs. The thyroid needs iodine. Seaweed and Kyo Green (#amazonaffiliate) are good sources that are assimilated well by the body. This has been a tremendous help in cutting through the fog for Clint and me. We took it in the evening and saw a noticeable change the next morning. The next day there was an even bigger change.
Dear Reader, IDK for sure if it will help you, but it certainly helped us. God designed our bodies to heal themselves, but we must give it what it needs to do this.
