Serotonin (5-hydroxytryptamine, or 5-HT) is a chemical in the brain (neurotransmitter) that helps to transmit electrical signals from one part of the brain to another. It is manufactured in the brain but is also present in the digestive tract and platelets. Serotonin also affects your mood, heart function, temperature regulation, sexual function, appetite and sleep patterns.
Serotonin Deficiency Syndrome: Causes
There are a number of contributory factors for serotonin deficiency syndrome, including hormone changes, long periods of intense stress, poor diet, genetic causes, poor metabolism, digestive problems, substance abuse and toxins.

St. John's Wort
St. John's Wort (Hypericum perforatum) is a yellow flowering plant that is native to the United States and Europe. It has been used for thousands of years in the treatment of many ailments. These days it is often used as an herbal supplement to reduce symptoms of depression which may be caused by serotonin deficiency. Over the past two decades, more than 30 studies have shown it to be effective. The suggested dosage is between 200 and 1000 mg of 0.3-percent standardized hypericin daily.
People with fair skin may have a sensitive reaction to sunlight while taking St. John's Wort. Do not use during pregnancy or while breast feeding. Do not use while consuming alcohol. Do not use along with other depression medications. Have blood pressure checked frequently while using.
Ginseng
Ginseng (Panax ginseng) is a leafy plant which produces flowers and red berries. Its dried root has been used for centuries in Chinese medicine. Some studies have shown it to be effective in reducing the symptoms of depression and mild anxiety. The suggested daily dose for a ginseng supplement is 200 mg. Side effects may include sexual dysfunction, nausea, headaches, diarrhea, insomnia, decreased appetite, euphoria and vertigo/dizziness.
Tryptophan
Tryptophan is one of the 14 essential amino acids that may only be obtained from food. Tryptophan is a precursor to serotonin; this means it plays an important role in the chemical production of serotonin. Levels of tryptophan in the brain can affect mood. Fortunately it is only required in trace quantities within our body. The recommended daily allowance for tryptophan is 0.2 g daily. To put this into perspective, an average person obtains 1-1.5 g per day from food; despite this, only a fraction of it reaches the brain. Foods containing tryptophan include turkey, chicken, beef, eggs, white rice, milk, russet potatoes, bananas and salmon.
