My husband had a very successful company and went to MIT in his younger years. He is 71 years old now and had Covid in 2020. He was hospitalized for dehydration twice and has had problems since from muscle, eyesight, brain fog and verbal communication (finding the correct words). In the last 3 months, since he started taking MCT oils, walking and eating healthy, miraculous things are happening. He is playing golf and shooting pool again and has a very positive outlook. Hope this is helpful.
