In this interview with Neil E. Levin, we are looking at nutrients that can influence mood, stress, sleep and tension issues. We are also considering nutrients for memory, brain acuity and concentration. There are often multiple factors occurring at the same time. If you have everyday stress in your life, you may not be sleeping well. If you don’t sleep well, it’s hard to restore your brain and this may affect your mood. This could lead to nervousness. Any of these can affect your quality of life.
