5-HTP increases serotonin levels in the brain which may positively enhance mood, sleep and weight management! How does NSI® 5-HTP 100 mg work? 5-HTP, or 5-hydroxytryptophan, is a precursor to the neurotransmitter serotonin - which is essential for controlling mood, sleep and pain levels. The body produces 5-HTP from tryptophan, an amino acid found in small amounts in high-protein foods such as chicken, fish, beef and dairy products. It can also be taken in supplemental form, in which case it's extracted from the seeds of the Griffonia simplicifolia plant. 5-HTP is believed to help increase serotonin production in the brain, which may positively influence mood. 5-HTP may also help with other health issues related to serotonin deficiency, including nervousness, body tension and stiffness and head cavity discomfort. Certain elements of sleep are also believed to be affected by 5-HTP. Supplementing may not only assist with falling asleep faster, but also with increasing the duration of dream states (REM sleep) and of deep slumber. 5-HTP may also promote weight management by helping to reduce cravings for sweets and starches, which may help contribute to healthier overall eating habits. For best results and quickest absorption, take 5-HTP on an empty stomach. Do not take 5-HTP for more than three consecutive months without consulting a healthcare practitioner. NSI® 5-HTP 100 mg is better because it:. Ideal for supporting mood, sleep, and weight management. Is available at a better value than other 5-HTP products on the market.

"I bought this product to help with anxiety. I do feel really good, but I also believe that happiness lies within anyway. So I'm not too sure how effective it is, but I believe that it has helped. As far as the weight-loss related properties, I will say that I think 5-HTP helps me to NOT be hungry. I think long-term use will tell more."

"I have been going through a stressful time in my life that has caused me restless sleep. I take this once in the morning with the rest of my vitamins. At first it made me sleepy during the day, but now it just helps me have a sound sleep at night without feeling groggy the next day. I only plan to take this temporarily."

"I can't say enough good things about 5-htp. Within 15 minutes after taking 1-2 capsules (on an empty stomach) I feel an elevation in my mood. Also, it will help you sleep better when taken about a 1/2 hour before bedtime. And, because it increases serotonin levels it can help curb your appetite for carbohydrates."

"I was taking another product with 5HTP called Mood Aid and it was more effective because of other ingredients with it. I thought using a stronger dose would increase the benefits, but it has had no effect after 3 weeks of using it. I still use the Mood Aid as if I wasn't taking the 100mg 5HTP."

"5-HTP 100 mg is a great Product! I have used it for some months, and I find it does help me loose a small amount of weight at a time. Twelve pounds in about 3 months, and it does help me not crave sweets and carbs. It helps with my back pain and I have no more trouble sleeping. Thank you for a great product!"

"The use of 5-HTP was recommended to me by specialist physician that manages my headaches. I was told I needed to increase my serotonin levels. I have tried many different brands of 5-HTP but I have noticed the biggest difference in my moods and in the severity of my headaches with this brand. I have also found that other brands include things that I don't want or need... this is pure 5-HTP."

"I started out taking one of these at night about an hour before bedtime for insomnia. Over time, the effects wore off so I increased the dosage to two capsules. The results are excellent. I fall asleep quickly, sleep soundly and wake up refreshed. These are much better than prescription sleep aids which leave me with a clouded mind the following day."

"I can't tolerate any type of ssri or any other antidepressant because of nervous side effects....5-htp twice daily seems to be helping the depression although it took a week or so...but this is the best supplement so far that seems to at least seem that it is helping and doing some good...this is just my opinion, everyone is different but I would recommend giving it a try if nothing else has worked..."

"I've been through the sleep studies, been to countless doctors and pretty much get the same story...prescription sleep aids. I am not comfortable using rx sleep aids unless absolutely necessary. I take one of these about 2hrs before I want to go to sleep and most nights it's enough to calm and relax me. My medical doctor shrugs it off, but I say if it works for you, then do it. As always excellent quality product and great value."
