Sleep Regulation, Mood Balance and Regulate Appetite with 5-HTP
5-HTP works because it supports your body’s balanced production of two important sleep regulating hormones, serotonin and melatonin. Serotonin is a neurotransmitter that helps regulate sleep, moods and appetite. But you need adequate serotonin levels to maintain this balance. 5-HTP is the serotonin precursor that is formed when tryptophan is converted into serotonin in your body. In clinical research, 5-HTP increased the amount and availability of serotonin produced by the body. It is able to cross the blood brain–barrier to increase both serotonin levels and serotonin production in your brain so you can regain a healthy balance when you are sleeping, feeling emotions, or eating.*

The 5-HTP is fantastic. I take it at night along with a very small dose of melatonin from the same company. The 1, 2 punch is a killer to my insomnia. Sweet sleep, and the side benefit of a cheerful mood. Not bad for such a little capsule.
It seems like everyone has different results from this drug but my experience is as follows.
I take 1x100mg in the morning and 1x100mg at dinner. (that's the 3rd meal for those who refer to lunch as dinner).
Effects: I sleep deeper through the night and have lots of dreams.
I used to wake up frequently during the night and couldn't get back to sleep. 5-HTP fixed that.
I used to have a hard time falling asleep. 5-HTP fixed that.
Ambien works but that made me do silly things and it didn't feel natural.
Melatonin sort of worked but gave me nightmares.
I've tried the over the counter concoctions with hundreds of natural sleep aids and those were hit and miss.
I don't have depression so I don't know if it's helped my mood or anything, just sleeping.
I've been on it for 6 months now but I took a hiatus on the 5th month to see if it was really doing any good. Within 2 days I was back to having a hard time sleeping and slept terribly for 2 weeks. Now that I'm back on it my sleeping soundly has resumed.
I recommend 5-HTP and this brand.
It has increase my positive mood.
Lessened my anxiety.
And kept me on track with healthy habits.
I have real bad depression and before I would only focus on that.
Now it seems I have more time on my hand and can do what I want.
I only need to take two pills a day. One in the morning and one at night.
A steady routine should be built. The effects aren't immediate. It takes affect in a week or two.
Great product at an affordable price. Really, GNC has it for $19 and it only comes with 30 capsules.
5htp can raise cortisol, so if sleep is your issue, you may not want to take in the evening. She recommends taking am throughout day and not in evening.
(I got a headache from another brand, switched to this one and no problem. Great brand)
Tryptophan does not raise cortisol, so that is great for before bedtime. Helps sleep!
together they work well, raise serotonin and help sleep.
The quantities can vary based on what different people need. These supplements can be enormously helpful for depression and sleep! getting good advice is worth it.
(The folks who wrote The Mood Cure can recommend people...fabulous help!)
