SerotoninWhat is a Neurotransmitter?
A neurotransmitter is a chemical messenger that carries, boosts and modulates signals between neurons and other cells in the body. In most cases, a neurotransmitter is released from the axon terminal after an action potential has reached the synapse. The neurotransmitter then crosses the synaptic gap to reach the receptor site of the other cell or neuron. The neurotransmitter is located at the tip of the synaptic end bulbs in-‐order-‐to continue the nerve impulse to the next neuron for a continued signal.

SEROTONIN-WHAT IS IT?
What exactly is serotonin? You may know something about it, that with out it you can be sad or some of the basics. Here you can learn more.
Serotonin, also known as 5-‐hydroxytryptamine is a hormone in the pineal gland, the digestive tract, the central nervous system, and blood platelets.
A hormone is a substance our body produces that regulates and controls the activity of certain cells or organs.
Serotonin is a Inhibitory, meaning it helps create balance in the brain.
Serotonin plays a big part in mood and digestion. Serotonin levels are responsible for controlling and regulating your appetite, memory, learning, muscle movement, sexual behavior, reproductive system, sleep, endocrine, renal, immune and gastrointestinal functions, and body temperature regulation.
So in short, serotonin plays a major role in your every day life. If you have been diagnosed with a serotonin imbalance, these are some natural suggestions to help restore them.
1. Exercise, 2. Eating enough protein and carbohydrates3. Getting enough sleep, going outside and getting enough light4. Working on having positive moods and emotions.

SEROTONIN AND DEPRESSION! Too low of levels of Serotonin can lead to depression. There are two types of drugs used to help patients with depression.
SSRIS (Selective Serotonin Re-‐uptake inhibitors)-‐ Target the Serotonin system by blocking the pumps which bring the serotonin back into the Axon after a signal. This causes signals to seem stronger and last longer.Examples of this type of medication are: Fluoxetine, Paroxetine, Zoloft, Lexapro, Celexa, Luvox, Venlafaxine, Cymbalta, and Bupropion.
MAOIs (Monoamine Oxidase Inhibitors)-‐ Oldest type of antidepressants and have more risks and side effects. They target the serotonin system by preventing the breakdown of serotonin in the body. This artiYicially raises serotonin levels.Some examples would be: Isocarboxazid. Phenelzine, Selegiline, and Tranylcypromine.
What happens if you have too much Serotonin?-‐ this can lead to sedation, nausea, vomiting, and diarrhea. What happen if you have too little Serotonin?-‐ it can cause depression, problems with anger control, obsessive compulsive disorders, suicide, and increased appetite. Also associated with migraines, irritable bowel syndrome, and Yibromyalgia.
Facts on Serotonin1. Serotonin levels are
affected by diet.2. Approximately 80
percent of the human body's total serotonin is located in the enterchromafYin cells in the gut, where it is used to regulate intestinal movement.
3. The most prescribed drugs in many parts of the world are drugs which alter serotonin levels.
4. In humans, defective signaling of serotonin in the brain may be the root cause of sudden infant death syndrome (SIDS).
