When the body needs a specific nutrient to do a specific job in a specific organ, that nutrient is found in higher concentrations in that organ. Vitamin C is found in high concentrations in many organs including the brain.
Vitamin C is important for many functions in the brain. As an antioxidant, it plays an important role in protecting brain cells from oxidative damage – the kind of damage implicated in Alzheimer’s disease. Vitamin C is also important for neurotransmitter synthesis – improving neurotransmitter levels is the therapeutic goal of many psychiatric medications. Vitamin C can be a basic part of many natural protocols for depression.
Vitamin C can can cause loose stools if taken in too large doses (this can be used to help with constipation). It is commonly used as a basic, supportive therapy for mood concerns like depression or anxiety.
