"I'd never had a problem with falling asleep, but would often wake up between 3 a.m. and 5 a.m. I take three capsules at bedtime and most of the time, get a solid 7-8 hours uninterrupted sleep. During times of anxiety and stress, I'll still wake up but I seem to be able to fall asleep much more easily. I plan to keep a bottle of this on my nightstand ALWAYS!"
"I take 3 capsules before retiring for the night. That helps me have a restful night's sleep. I especially like it because I have multiple allergies and it is free of the foods that I cannot consume. It is also free of starch, sugar, salt, preservatives, and artificial colors, flavors, and fragrances."
"I am 46 years old and very active (kickboxing, trailrunning and more) and had trouble (despite my physical tiredness) staying asleep. Melatonin didn't help...no matter how high of a dose I took. Now that I found out about L-Tryptophan...I take 3 capsules with some water right before bedtime and don't wake up anymore until my alarm goes off. I wake up refreshed and ready for the day."
"I started taking L-Tryptophan and glutamine before bedtime. I seem to sleep more 'efficiently' ( sleep approximately the same amount of time as before) but wake up with more energy that before I took them."
"I used tryptophan years ago. Then they took it off the market. I am so glad it is back. I have tried lots of other products for sleep and this one works for me. I am an insomniac and this is a safe way to quickly fall asleep. No hangover feeling the next day. I trust this brand. It is gluten free and that is essential for me."
"I take this for increased Seritonin production which improves sleep. I've had modest improvement in sleep. Although I prefer Meletonin before bedtime, it's good to take both together. My sleep is inconsistent so I don't always sleep the same so, therefore, I cannot accurately say if Tryptophan has all the benefits I'd hoped, but I take it knowing it also cannot hurt. Doctors' I spoke with said the same; it cannot hurt. L-Tryptophan is a good product and can be utilized for whatever health benefit the user desires."
"I have nothing to compare this to since it's my first experience with amino acid supplements. However, after 7 pregnancies and 6 children, I have suffered a great deal with poor sleep habits. It's an hour or THREE to fall asleep, then up a few times through the night and once I'm disturbed from sleep, I am unable to return no matter how much I relax or try again. My first night with this product, I don't even remember falling asleep. I just know that I was sleep and sleeping good and I was absolutely amazed when I awoke in the morning at 7am! One caution: if you don't go straight to bed and try to fall asleep after you take these, they will only make you relax and you will not be able to go to sleep for several hours later. USE AS DIRECTED: "within 30 minutes of going to bed." I will continue to use until I am well again."
