Wondering what this new ingredient is? Well, it is not new! Most of us have been eating it, not knowing it exists. Choline is a nutrient that if found in many foods. Our brain and nervous system desperately need it to regulate memory, mood and muscle control. This nutrient in our brains can make acetycholine, that is a neurotransmitter linked to memory and learning. Its food sources are eggs (especially yolk), salmon and even cauliflower. If one has low levels of choline, that has been linked to poorer cognitive function over time. It also has the necessary nutrients required for brain activity, hormonal balance, and effective immune system functioning. Choline, for example, which is present in high quantities in the yolk, is necessary for cell membrane function and neurotransmitter formation. A study published in the National Institute of Health says, Choline has been identified as one key nutrient affecting major brain processes, including neurogenesis, neuronal differentiation, myelination
