5-HTP Uses, Dosage, Side Effects & Contraindications
What is 5 HTP
5 HTP is the metabolic precursor to the neurotransmitter
serotonin. Tryptophane, an essential amino acid, is metabolized into 5-HTP by the body. 5 HTP
is in turn, converted into the neurotransmitter Serotonin. Serotonin is responsible for mood,
hunger and sleep. Antidepressant drugs approved by the FDA, including selective serotonin
re-uptake inhibitors (SSRI's) such as Prozac, are said to work by increasing the amount of
serotonin available to the brain. 5 HTP, therefore, may for some individuals, serve as a
natural alternative to some prescription SSRI type drugs like Prozac.
Supplementing either Tryptophane or 5 HTP increases
Serotonin levels by supplying more of the building block material needed to make this
neurotransmitter. Low levels of Serotonin have been associated with depression, fibromyalgia,
chronic pain, altered mood, insomnia, PMS, and headaches. Both tryptophane and 5 HTP are
sometimes used as nutritional support for these conditions. 5 HTP is about five times more
potent than Tryptophane for this application.
5 HTP for Mood Elevation, Depression and Panic Attacks
According to medical journals and reviews it has been
proven that 5 HTP helps improve the mood of depressed patients and helps panic attacks. The
same sources generally recommended that more research on 5 HTP should be done before claims
were made.
5 HTP for Sleep and Weight Loss
5 HTP may aid in weight loss and improve sleep patterns
for some individuals. Research suggests that good serotonin levels may reduce appetite
thereby assisting in weight loss. Serotonin is converted into melatonin in the pineal gland
and melatonin, in turn, regulates sleep cycles. The theory is that if 5 HTP can increase
serotonin levels, it may be able to improve sleep and aid in weight loss. In the medical
articles reviewed, positive results have been reported but the authors caution that more
research is needed before claims can be made.
5 HTP Dosage
As with all nutritional supplements or medications,
individual response is a variable. It is clear that large excesses of serotonin in the
peripheral circulation can cause cardiovascular disease and other adverse effects. Too much
5 HTP in the diet could potentially result in too much serotonin in the peripheral
circulation.
Some sources suggest that 5 HTP can be safely used as a
nutritional supplement at a dosage of up to 100 milligrams (mg) per day. Some authorities
maintain that much larger dosages can be consumed without adverse effects. Some also suggest
that 5 HTP, especially in larger doses should be used with the prescription drug carbidopa.
The purpose of this drug is to prevent the 5 HTP from being converted to serotonin in the
peripheral circulation.
5 HTP Precautions & Side Effects
5 HTP is available without prescription and is generally
considered safe and may be beneficial for many individuals. Contraindications to 5 HTP use or
conditions under which 5 HTP use should only be under the supervision of a physician are
conditions in which increased serotonin levels may be harmful. This list is generic and
does not represent a contraindication for all individuals. Obtaining professional advice is
advised, especially if prescription medications are also being used.
- Cardiovascular Diseases (high blood pressure, post-stroke, post-heart attack)
- Extremely Elderly Persons
- those with Parkinsons Disease, Cancer or Autoimmune Diseases (Scleroderma, Rheumatoid Arthritis, Multiple Sclerosis, Lupus)
- Lung Diseases
- Chronic Alcoholism
- Liver diseases (hepatitis or cirrhosis)
- Parasitic Infection
- AIDS
- Anorexia Nervosa
- Low protein Diets
- Allergies (severe)
- Myalgia (persistent pain and weakness of the muscles)
- Peripheral Neuropathy (pain weakness of the muscles)
- Rash or Flushing
- Edema
- Nausea
- Diarrhea
- Sickle cell anemia
- Hemophilia
- Pregnancy
Concurrent drug use: 5 HTP should not be used if taking:
- Anti-depressant drugs
- Monoamine Oxidase Inhibitors
- Selective Serotonin Reuptake Inhibitors (SSRI's e.g., Prozac)
- Tricyclic medications
- Weight Loss medications (i.e., dextenfluramine)
- Anti-parkinson medications (e.g., L-dopa)
- Barbiturates and other tranquilizing drugs
- Antihistamines and cold medications
- Alcoholic beverages
- Intravenous (illegal I.V.) drugs
- Cancer Chemotherapy
- Antibiotic Medications
The principal reason for not combining 5-htp with these
classes of medications is that many of them may also increase serotonin levels or affect
other neurotransmitters, but by different biochemical mechanisms. The combination, in some
cases, has the potential of acting synergistically to dramatically increase serotonin levels.
This combined action could have adverse effects.
Alcohol and 5-HTP should not be taken together. Allow at
least six hours between use of alcohol and 5 HTP.
Warning: 5 HTP can increase the effect of some tranquilizing drugs.
Additional Natural Supplements with Anti-Depressant Effects
Other supplements that have anti-depressant effects include:
SAM-e,
St. John's Wort
and Inositol.
