Product Information


Relaxing, Promotes Positive Mood

Helps Control Appetite and Promote Normal Sleep

5-HTP 200mg Time Release has a delivery system that releases 5-HTP slowly and then steadily over a period of time. 5-HTP is a drug-free, amino acid derived from plant that naturally increases the body's level of serotonin, the chemical messenger that affects emotions, behavior, appetite, thought and sleep. Today's stress filled lifestyles and dietary practices may negatively affect how the body handles serotonin. Regular use of 5-HTP 200mg Time Release helps promote a more positive outlook and greater appetite control.*

Helped with PMDD
I have SEVERE PMDD,premenstral disphoric disorder, which is caused by low seretonin levels. 5 HTP has helped me more than anything I have tried to treat my PMDD. I had migrains, depression, anxiety, uncontrolable appetite, name it. I tried all kinds of perscriptions, even surgery. Since taking 5 HTP daily my symptoms are finally under control. I recommend this extended release 5 HTP, it works the best.

Will reduce anxiety & cravings.
I heard about this pill on a TV program about weight loss. The speaker was a brain surgeon. He said that low serotonin levels in the brain trigger anxiety & depression, and for some people, food is their comfort. I don't have a weight problem, but this pill has removed my cravings for nicotine ... which comes with the stress of being a trial lawyer.

Miracle in a Bottle
I suffer from PMDD (premenstrual dysphoric disorder), which is a very severe form of PMS, and I had heard that 5-HTP helps treat that along with mood swings and other emotional issues. I was really skeptical because I've tried several other things that weren't very effective and I thought this sounded too good to be true. Shortly after I started taking it I noticed that I felt more calm, and much less moody and emotional. Once I hit the point when my PMDD should've kicked in I could tell a HUGE difference. It was more like mild PMS and I never got crazy emotional or bawled my eyes out for no reason. My hubby loves this stuff since it's pretty much vital to his well being ;) He calls it my "happy pill" and makes sure I take it every night. I take it before bed because it makes me a little sleepy and actually helps me sleep better. It also improves my stress/anxiety level, which is great because I'm an RN and my job can be extremely stressful. I've started recommending this to everyone I know who suffers from PMDD/PMS, depression, mood swings, stress/anxiety, or emotional instability. I've gone through several bottles now and am super happy with the results. It's worth every penny!

Must-Have for Anxiety
After trying some samples, I wanted to try the real deal. I have been taking this every day for the last month, and as a senior in college who suffers from severe anxiety and depression (leading to frequent insomnia), this has truly been a godsend. I have had no anxiety attacks since using this supplement. My anxiety is low to none. I can get to sleep easily and sleep through the night, feeling well-rested every morning. I truly can't say enough about this product. If you suffer from anxiety, depression, and the like, definitely give this supplement a try. I take it every morning with my other medications and it quite honestly has changed my life for the better.

It works, but....
I'm on a Seritonin uptake depression medication. I'd been having trouble sleeping and staying asleep. Consiquently, my depression/anxiety and fibromyalgia flared up frequently, particularly when I was under stress. Exercise didn't help the depression or the fibro. I started on 200 mg. It was great at first: I took it before bed and I fell asleep as soon as I got in bed, I felt refreshed as soon as I woke up and I had more energy throughout the day. I usually had vivid dreams, so these were even more vivid, but they weren't bad dreams. After about a month on the 5HTP, the dreams started getting bad - visions of being abandoned (something I was going through in real life) and I became depressed due to the disturbing dreams and feeling down all day. I began cutting the pills in half (although that alters the time-release). Since doing so, no more bad dreams, and it DOES help me go to sleep almost an hour after I take them at night. However, I'm starting to wake up in the early morning hours before it's time to wake up and the energizing feeling doesn't last throughout the day anymore. I'll still take it (just getting enough rest is worth the price), but I'm disappointed that it doesn't last as long. Maybe I'll try the 100mg with the time release intact so it'll last all day. Be sure and check with your doctor about taking it if you're taking any SSRI anti-depressants or any anxiety meds. Overall, I'd recommend anyone to give this a try!

Great Mood enhancer
I've been taking 5-htp for a couple of years now. I find that it works well with my sleep as I am a very light sleeper. When I take the 5-htp I find I have a restful sleep and wake up a bit more energized. I also do take it as a mood enhancer. I began taking it after I had my child – because of post-partum – and I continue to take it as – I tend to have major mood swings and find I am more myself – or at least my mood is balanced when I do take it.

Helps my Fibromyalgia pain
I have fibromyalgia and tried Lyrica and a bunch of other prescription drugs that help initially but have bad side affects. I weaned myself off of Lyrica and decided to do some research on my own. 5 HTTP helps me to get a better nights rest which is a major factor in fibro flare ups. I still get flare ups (mostly in cold, damp weather) but not as many as before (even with the prescription meds).

Works as advertised
This product works as advertised.

A men's magazine recommended this product, so I thought I would try it out.

I have been sleeping extremely well since I have begun taking this product.

I will keep a bottle in my vitamin cabinet at all times now.

Maybe pricey, nevertheless worth it.
Would also recommend L-DOPA or L-Tryosine (either one or both help), to increase dopamine levels which complements 5 HTP supplements (serotonin). Retrospect, both serotonin and dopamine will assist suffers with depression.

Better when I take it than when I don't.
I don't notice any earth shattering boost in anything when I take this but I do notice I struggle more with mild depression when I don't. It seems easier to cope and I don't find myself teary as often. So, while not a huge difference, it seems to be just enough to stay on a more even keel.
