I think most of it could be related more to fatigue and brain fog that goes along with the Rona recovery. Concentration wanes easily. The jabs are a whole other issue. The recipes in the jabs could be targeting the VMAT2 gene. We don't know and to speculate that at this point may be premature without more information. But, the gene is real and it does seem to be linked with an increase in religious belief in the individual that expresses that gene.

When I had the crud a couple of months ago I used the treatment protocols to fight the illness. Once over the initial acute phase, it is important to move into a recovery phase and give the body what it needed to heal. Cognitive support for me was important because of the brain fog issue I had read about. Cordyceps, CoQ10, good fish oil, Phosphatidylserine/phosphatidylcholine, and standardized Gingko. These I took in addition to the normal supplements I usually take anyway. It really seems to have helped me turn the brain fog corner.
