Enteric delivery reduces the potential for stomach upset while preserving the active ingredient for optimum absorption and bioavailability.

Customer Ratings & Reviews

Rated 4.2 out of 5 by 25 reviewers.
Rated 1 out of 5 by Harsh Despite being enteric coated this was had on my stomach and I had to switch back to my old brand. December 29, 2014
Rated 4 out of 5 by Works for me! This is a newer product for me to try. I feel like it is helping feel calmer and my sleep has improved. August 12, 2014
Rated 1 out of 5 by Poor Quality The enteric coating was cracked and many of the capsules were not in one piece. Despite that I tried them as I had ordered 3 bottles, However they were not effective at all. Have switched to another brand (Natrol) which is more effective. January 11, 2014
Rated 4 out of 5 by Best Price on 5-HTTP Can't beat the price for the product. Very effective product! After much research, best price found! October 10, 2013
Rated 5 out of 5 by The Best Yet The Best Yet. I have tried other 5htp products but they have not worked for me and this one works. I do not use to for sleep, more to regulate my mood along with St. Johns Wort. Great product. August 26, 2013
Rated 3 out of 5 by it depends I bought this for mood improvement which it did not do. It did help with sleep, so I got one out of two with this. But, it's not the one for me regarding mood improvement. August 7, 2013
Rated 5 out of 5 by Amazing supplement This works perfectly! Amazing. August 4, 2013
Rated 5 out of 5 by Healthy Night's Sleep Believed to help promote healthy sleep and possibly help promote the natural production of HGH 5-HTP is a regular part of my nighttime regimen.. June 30, 2013
Rated 5 out of 5 by Good Product I take two of these before bedtime, and they work very well. Enteric coating on 5-HTP supplements is important, and this is a great price. June 5, 2013
Rated 5 out of 5 by No more upset stomach- good product I'd taken the non coated 5-htp & always had mild nausea a short time later. I tolerated it since 5-htp really helps my sleep. This coated 5-htp product is excellent- no more nausea, and the price is reasonable. June 1, 2013
Rated 5 out of 5 by No stomach ache I have tried several other brands with 5HTP, but they all gave me stomach ache. Exept for this one from Swanson! Great! I'll take it in the morning because it give me energy ...and also my 'Happy pill'! Thank you Swanson! May 26, 2013
Rated 5 out of 5 The Mecca of 5-HTP supplements I have spent quite a bit of money on 5-HTP supplements for many years now. From the raver days to the cloudy days when I just needed that extra bit of serotonin, these always have done the trick. Every time, without fail. Many other supplements at equal strengths have just not made a noticeable difference compared tot this one. I'm thinking its effectiveness is provided by its enteric coating that is just marvelous. One of the new supplements I always order 2 of and keep them on deck, always. A++ April 24, 2013
Rated 5 out of 5 by Best 5HTP The only draw back to 5htp is the stomach upset, this is the only 5htp that is encoated to protect the stomach lining. I love this product! NO stomach upset and it works! This is the ONLY place I will buy 5 htp. I only wish they sold this in bigger bottles. March 14, 2013
Rated 5 out of 5 by 5HTP enteric coated Not hard on the stomach at all, really helps regulate my sleep and mood. As an added bonus helps me lose weight quicker than my diet and exercise alone Huzzah! March 3, 2013
Rated 4 out of 5 by good purchase While I don't know how much this product has helped me to sleep, I am impressed that it hasn't caused stomach upset as another 5-htp brand which is why I'm recommending it. February 21, 2013
Rated 3 out of 5 by Problem with coating The enteric coating on the 5-HTP cracks and breaks. I think the bottle should contain an absorbent because of humidity to keep the coating intact. Other than that, the product is really good. February 14, 2013
Rated 5 out of 5 by Caps vs. Tabs I have always had a problem with capsules, they stick in my throat. When I started using 5-HTP to get the right dosage I had to get capsules until the enteric coated tablets showed up as a new product. I really like them I get the right dosage, I can swallow them easily, and the price is very good :) May 5, 2012
Rated 5 out of 5 by This is a Great Mood Booster The 5-HTP stands for Hydroxy Tryptophan, which is a precurser for creating Seratonin naturally in the body. This works amazingly well for uplifting overall mental outlook as well as making things sharper such as memory , focus, and ability to function overall in a more healthy fashion. As always, Swanson combines top quality with great value. I am very well pleased and plan to continue to use this product indefinitely, as well as providing it to my daughter. April 12, 2012
Rated 5 out of 5 by Compares favorably Just as good as the more expensive brands I have used before March 31, 2012
Rated 5 out of 5 by Sleeping through the night Menapause started a cycle of waking up numerous time during the night and difficulty going back to sleep. Since the first day I started taking this, I've been sleeping through the night more often than not and when I wake during the night, I go back to sleep faster. I find I'm less irritable in general. March 31, 2012
Rated 5 out of 5 by Very good product I have excellent results with this product. I take one in the morning and two before bedtime. I can finally get deep sleep. My husband and mother both take the same product and also have very good results. March 30, 2012
Rated 1 out of 5 by Did not help! I purchased this hoping it would help me get a good night sleep. It did not work. November 21, 2011
Rated 5 out of 5 by Great product! I have been using this for a few weeks now and I am very happy with the results! It works like it should! August 14, 2011
Rated 5 out of 5 by love this!! I waited to write a review to make sure this works well for me. I have used it now for several months. The enteric form works better for me. I take two a day, one in am and one in pm. And this makes me a very happy camper in more ways than one. Please keep this in stock as it really beats the other brand's prices. Thanks Swanson!!
