iHerb Customer Reviews

I recommend this supplement wholeheartedly! I can't say enough great things about it. I very thoroughly researched different brands of 5-HTP and found that this brand was the best. The first reason I chose this brand was because they are one of the few brands to state that their product does not contain Peak X. Peak X is a toxin that is linked to the development of EMS in 1500+ consumers who were taking 5-HTP supplements back in the '90s. Luckily I had read a review from an awesome consumer who mentioned this in their review, so I want to inform others of this toxin so that more people will purchase safer health products. I also purchased this brand because of the really great reviews I found online, as well as the fact that this 5-HTP is gluten free and does not contain fillers or other unwanted ingredients. Now to the review: I started off by taking only half a capsule every night for a week (50 mg). I'd break open the capsule, pour the powder onto a little dish and put half under my tongue for about a minute before swallowing down with water, saving the other half of the powder for the next night. The first night I took this, very quickly I began to feel very calm and relaxed, literally as if I had taken a Xanax. It was a really awesome feeling. I slept amazingly well that night. I only felt that kind of high that one night, obviously because my brain was adjusting to the supplement. After a week, I upped my dose to a full capsule every night, about an hour before bed. I continued to break open the capsule and pour the powder under my tongue, hold for about a minute and swallow with water. The taste of the powder is really pleasant, unlike other supplements I decided to take sublingually. I've been taking this 5-HTP for about two months or so and the effects are still noticeable. About a half hour after I take this, I become relaxed, happy and sleepy but I do not feel like I'm drugged whatsoever. I can definitely see the different in my mood, appetite and sleeping patterns. I did have very vivid dreams when I started taking this supplement, and occasionally still do, but I've never had any nightmares at all on this stuff. I highly recommend this 5-HTP for anyone with sleep issues, weight concerns and/or mood imbalances. I plan to buy and use one more bottle before I take a break, since the recommended period of time to take this is about 12 weeks, although I'm not sure that prolonged use can cause adverse effects. Definitely do NOT take this product if you take any type of antidepressants or have Bipolar Disorder. If you do have an adverse reaction after taking 5-HTP, you may not have very low levels of serotonin, therefore you won't need this. If that is the case, look into taking Melatonin, for sleep, weight and mood imbalances. **If you find my review useful, click "YES" and see more useful info by clicking on my name.**

Not sure about effects

I want to believe that this is effective, but not sure. It bothers me also that it is recommended taking it on an empty stomach.
