Mental fog with CFS is a major challenge and can often result in failure to maintain a protocol, pushing beyond your current CFS “envelope”. In my last post there were several herbs and spices that helped the brain (neuroprotectors). In this post, I will add a list of similar items not in the last list and which are not probiotics (a future post)
- Piracetam and all of the other Racetams
- Alpha-Lipoic Acid
- Flushing Niacin and other vasodilators.
- Fish Oil 
With the earlier Neem and Tulsi being my additional favorites.
Anticoagulants improve blood flow and thus reduce mental fog. They also tend to increase penetration of antibacteria and antivirals (in some cases 10x more concentration for some antibiotics)
- heparin (prescription)
- Coenzyme Q10
Many of the top list are also anticoagulants.
