  • 5-Hydroxytryptophan (5-HTP) is the intermediate metabolite produced when the body initiates the process of converting the essential amino acid L-tryptophan to serotonin. Serotonin levels in the body are associated with the regulation of sleep‚ mood‚ aggression‚ appetite‚ temperature‚ sexual behavior‚ and pain sensation.

    Supplementing with 5-HTP to facilitate serotonin production is preferable to supplementing with L-tryptophan because‚ unlike L-tryptophan‚ 5-HTP cannot be shunted into niacin or protein production. Supplementation with 5-HTP bypasses the conversion of L-tryptophan into 5-HTP by the enzyme tryptophan hydroxylase‚ the rate-limiting step in the synthesis of serotonin and a step that can be inhibited by a number of factors‚ including stress‚ insulin resistance‚ increasing age‚ and deficiencies of vitamin C‚ folate‚ and iron.

    5-HTP is well absorbed when taken orally‚ with about 70 percent ending up in the bloodstream. Intestinal absorption of 5-HTP doesn’t require the presence of a transport molecule and is not affected by the presence of other amino acids; therefore‚ it may be taken with meals without reducing its effectiveness. 5-HTP easily crosses the blood-brain barrier and effectively increases central nervous system (CNS) synthesis of serotonin.

    5-HTP has been shown to have a beneficial impact on mood‚ discomfort associated with fatigue‚ sleep‚ and carbohydrate craving. Several studies of individuals with negative mood status have shown significant positive response with 50-300 mg of 5-HTP daily.

    To further facilitate serotonin production‚ Thorne Research's 5-HTP formula contains the active form of vitamin B6‚ pyridoxal 5'-phosphate‚ which is necessary in order to convert 5-HTP to serotonin. 5-HTP is commercially produced by extraction from the seeds of the African plant‚ Griffonia simplicifolia.

    Each dose of two capsules provides 100 mg of 5-hydroxytryptophan. One bottle of 5-Hydroxytryptophan by Thorne Research provides 90 vegetarian capsules‚ which will last for about 45 days at the recommended dosage.

    Thorne Research strives to provide pure‚ high-quality supplements to people looking to enhance their health and well-being. Its products are commonly used in prestigious research studies‚ and are recommended by many doctors and health care practitioners.

    Serving size is weird

    The serving size is two capsules and I didn't realize because usually 5-HTP doses of 100 mg are just one capsule. 5-Hydroxytryptophan by Thorne Research works well though but shouldn't be used without the direction of a doctor.


    Pros


    Cons

      Serving size.

    I would recommend this item to a friend.

    Not my favorite

    5-Hydroxytryptophan gave me stomach ache. I prefer the sub lingual version as it doesnt create a stomach ache.

    good recommendation

    My ND recommended 5-Hydroxytryptophan to help sleep taking one at night. I was also very anxious and overwhelmed at work and the next time I saw her she said to take one in morning as well. It really helps with the anxiety and sleep but my mind is still very sharp and creative at work and I dont have the side-effect of vivid dreams that some people do.

    it works

    Within days of starting 5-Hydroxytryptophan I experienced reduced carbohydrate cravings and feel more rested. So far I am taking 5-Hydroxytryptophan at bedtime only as it does seem to cause some drowsiness.

    It works

    I needed something to help with depression. My ND recommended 5-Hydroxytryptophan to me. This does work to lift my mood. It also helps control my anxiety. I found too that it helps promote healthy sleep. I take one in the morning and one in the evening.


    Pros

      works quickly small pill

    Cons

    Great Product!

    I have been taking Thorne 5HTP for over 2 weeks now. I am feeling great! I was taken it because my Serotonin level was very low. 5-Hydroxytryptophan has helped alot.


    Pros

      How it has made me feel better.

    Cons

      It did give me an upset stomach at first and it at times does give me heartburn.

    I would recommend this item to a friend.
