Protein powder shows promise for clearing Post-COVID 'Brain Fog'

This study tested whether a daily whey protein supplement called Immunocal could help improve memory, attention, and fatigue in people with 'long COVID' brain fog. 120 adults in Colombia who had recovered from COVID-19 but had ongoing thinking problems were randomly assigned to take the supplement, do brain training exercises, or receive no special treatment for 12 weeks. The group taking the protein powder showed significant improvements in memory and attention, similar to the group doing brain training, and also got better at a physical endurance test.
