About 5-HTP

5-Hydroxytryptophan (5-HTP), also known as oxitriptan, is a naturally-occurring amino acid extracted from the beans of an African plant, Griffonia simplicifolia. It is a chemical precursor as well as metabolic intermediate in the biosynthesis of the neurotransmitters serotonin and melatonin from tryptophan. The positive mood supporting action of 5-HTP is thought to be derived from its effect on the production of serotonin in the central nervous system tissue.*

Frequently Asked Questions

What is Peak-X?
In 1998, researchers at the Mayo Clinic asserted that they had found trace levels of Peak-X, a substance linked to EMS-like illness, in commercially available 5-HTP supplements. As a result, it became necessary to screen for the presence of this contaminant to ensure that all of the 5-HTP available in the marketplace were Peak-X free. 5-HTP Gold is manufactured using a 5-HTP extract that is guaranteed by an independent, third-party lab to be Peak-X free so you can be assured that you are getting an exceptionally pure product.

What is the active ingredient in 5-HTP Gold™?
The active ingredient in 5-HTP Gold™ is L-5-Hydroxytryptophan, a naturally-occurring amino acid, found in the beans of Griffonia simplicifolia, a plant native to the African sub-continent.

Does 5-HTP Gold™ contain anything other than the active ingredient?

In addition to the active ingredient, 5-HTP Gold™ contains some rice concentrate. Because natural extracts can vary from batch to batch in terms of consistency, moisture (or stickiness) and particle size, it is sometimes necessary to add rice concentrate during the manufacturing process to help ensure product integrity without compromising product safety or effectiveness.

Is 5-HTP Gold™ free of allergens and GMOs?
5-HTP Gold™ is verified free of egg, gluten, milk, peanut, shellfish, and soy by an independent lab. It is also verified non-GMO by the Non-GMO Project™.

Is 5-HTP Gold™ suitable for Vegans / Vegetarians?
5-HTP Gold™ does not contain any animal-derived ingredients and is, therefore, suitable for both vegans and vegetarians.

Is 5-HTP Gold™ habit forming?
When taken as suggested, 5-HTP Gold™ is not habit forming. If you have any concerns about sensitivity to 5-HTP and/or developing a dependency on the supplement, please talk to a licensed medical professional before beginning supplementation.

How long does it take to notice benefits?
Unlike OTC and prescription drugs that provide instant, temporary, symptomatic relief, herbal supplements provide progressive, long-term benefits by strengthening and supporting the body's natural defenses. Most herbal supplements, including 5-HTP Gold™, need to be taken for at least 6 to 8 weeks before the benefits of taking the supplement can be experienced. Please be advised that nutritional supplements work best when they are taken as part of a health maintenance program that includes a sensible diet rich in whole grains, fruits, and vegetables, a moderate exercise program, and the necessary lifestyle changes to support wellness.

What are the side effects, interactions, and/or contraindications, if any, associated with 5-HTP Gold™?
5-HTP may interact with certain anti-depressants, SSRIs, pain medications, cough medications, or any other OTC or prescription medication. Please consult a healthcare professional before using this product if you are currently taking or planning to take these, or any other OTC or prescription medication, if you are pregnant, suspect you may be pregnant, are breastfeeding, or if you are planning a medical procedure. This product may cause drowsiness, so please exercise extreme caution when using.

Is 5-HTP Gold™ safe for long-term use?
Although 5-HTP is extremely well-tolerated and should be safe when used as directed, there are no reports about the risks and/or benefits of long-term supplementation with 5-HTP Gold™. Further, individual experiences and reactions do vary considerably even with the same supplement, so we recommend consulting a healthcare professional before taking this product if you have any concerns regarding long-term use of 5-HTP Gold™.
