  • Enhances sleep and helps manage stress

    5-HTP increases serotonin levels to promote restful sleep‚ manage stress‚ and decrease sugar cravings. It contains pyridoxal 5'-phosphate‚ the active form of vitamin B6 and the necessary cofactor for the conversion of 5-HTP to serotonin.


    The serotonin levels in the body are associated with the regulation of sleep‚ mood‚ and appetite. A balanced serotonin level has been shown to support restful sleep‚ good mood‚ and decreased sugar cravings. There are several ways to support a healthy serotonin level. L-tryptophan and 5-Hydroxytryptophan (5-HTP) are both precursors to serotonin. However‚ supplementation with 5-HTP is preferable‚ because unlike L-tryptophan‚ 5-HTP cannot be shunted into other uses in the body‚ such as niacin or protein production. 5-HTP is well absorbed by the body and easily crosses the blood-brain barrier where it can increase the synthesis of serotonin in the central nervous system. And 5-HTP can be taken with meals without reducing its effectiveness.

    5-Hydroxytryptophan (5-HTP) is the intermediate metabolite the body produces when it initiates the process of converting the essential amino acid L-tryptophan to serotonin. Therefore‚ supplementation with 5-HTP will bypass the conversion of L-tryptophan into 5-HTP by the enzyme tryptophan hydroxylase – which is the rate-limiting step in the synthesis of serotonin – and is a conversion 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 going into the bloodstream. Intestinal absorption of 5-HTP does not require the presence of a transport molecule‚ and its absorption is not affected by the presence of other amino acids; therefore‚ 5-HTP can be taken with meals without reducing its effectiveness. 5-HTP has been shown to have a beneficial impact on mood‚ sleep‚ carbohydrate cravings‚ and discomfort associated with fatigue. Numerous 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's 5-HTP formula contains pyridoxal 5'-phosphate‚ the active form of vitamin B6 and the necessary cofactor for the conversion of 5-HTP to serotonin. 5-HTP is commercially produced by extraction from the seeds of the African plant‚ Griffonia simplicifolia.

    Worth the money!

    My chiropractor recommended 5-Hydroxytryptophan by Thorne Research to me after explaining issues of not sleeping well. I have noticed a huge difference in how I feel going to bed after having taken 5 HTP. Paired with some carbs (sweet potato) before bed, I am now sleeping through the night without night sweats and waking 2-3 times.


    Pros

      Highly recommended! Love this company!

    Cons

      None.

    I would recommend this item to a friend.

    5-HTP

    I am more relaxed since taking 5-Hydroxytryptophan from Thorne Research and the jury is still out on the effects on sleep.


    Pros

      Improved coping.

    Cons

      There is much discrepancy in the dosage. Instructions say take 2 caps and a recommendation is take 1-2 : 3 x a day.

    I would recommend this item to a friend.

    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

    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.
