How Calcifediol Works
Calcifediol works by increasing the activity of serotonin and decreasing the activity of serotonin receptors in the brain.
Serotonin is a neurotransmitter that is found in the brain and in other parts of the body.
It helps control body functions, such as sleep, mood, and appetite.
Serotonin receptors are located in the brain and throughout the body.
Calcifediol may also decrease the activity of norepinephrine, which is a neurotransmitter that helps regulate heart rate and blood pressure, and dopamine, which is a neurotransmitter that regulates movement.
