Review: Works very well for mood and sleep. - I have received no remuneration of any kind from the seller, or associates. No coupons, or promises of a refund, no free product for a review, or any other type or kind. I have no connection with the company whatsoever except as a purchaser. I am not connected by friendship, marriage or business with the seller or their associates. I paid for this product with my own money and I am giving my honest opinion about the product and the retailer. I like this tryptophan powder, it has nothing at all in it except tryptophan. I have noticed people complaining that it doesn't dissolve in water. Put it in your morning coffee. It doesn't really taste like anything, or smell like anything, the texture is a fine powder like cornstarch, and it will mix in the coffee. It works well to support mood and sleep. Just make sure not to put it in boiling hot coffee/tea/cocoa/juice/whatever because it is a protein, and proteins are destroyed by very high temps. The smallest bag has lasted me oh, I'd say 6 months. Try this BEFORE you go on to Melatonin. I take a dose before bedtime, It takes about a couple of hours to move through your system and do the conversion to melatonin. It makes my sleep so much better. I also take valerian root powder before bedtime, it helps with deeper sleep. If it doesn't work right away don't be impatient, give it at least 30 days, some people take 60 to 90 days to see a difference, it depends on your specific individual chemistry. Some things can take as long as 90 days for you to notice a difference, herbs and proteins and things are not instant fixes. For example St John's Wort usually does take 2 to 3 months to give a noticeable result, so do a lot of other herbs and natural remedies. If it still doesn't work, and the smallest bag should last at least 3 months, then the problem may not be melatonin. It is important to reduce systemic inflammation no matter what you take for sleep. Because systemic inflammation no matter the cause will cause sleep disturbances. Also, you may have sleep apnea and don't even realize it. Get a sleep study done. Or have someone observe you while you sleep, to see if you snore or stop breathing multiple times per night. If you do, go to your doctor. If the bag bothers you, save your glass condiment jars, and remove the labels with goo gone. or something similar; acetone helps, krud kutter does a good job, so does washing soda, vinegar can help too, barkeepers friend, just let them soak for a day or so and let the solutions do the work for you. Wash them well, and dry them well, put a small, wrapped package of rice, use an empty tea bag or something similar, in the bottom of the jar to absorb moisture, or if you have some moisture absorbers that came from supplement containers that are empty, take those and dry them thoroughly in the oven or dehydrator at very very low temperatures, not more than say 90 degrees, and then use those. You don't want extremely high temperatures because the paper will catch fire and the contents can melt. You just want enough heat to dry them out and they can be reused. If you have oxygen absorbers that would be good too. Those unfortunately cannot be reused as far as I know. If you have one of those jar sealers that suck the oxygen out that would be good, or a food sealer with that function. Then use a funnel to fill your jar, it's much less messy than using a spoon because of the fineness of the powder. Then you don't have to worry about the bag, and you don't have to spend money on containers. REMEMBER to label your jar. If you don't have a label maker, no need to buy one. Cut the name off the bag and tape it to your jar, or use you preferred method. Do the same for the instruction and dosage information. You might not want to use a permanent way of sticking on the labels though, because you might want to use your jar for something else later. You can also use empty supplement bottles, just label them and use a funnel to make it it easier to put the powder in. Then take a rubber band and put it on the outside of your container and slide your dosing scoop under the rubber band. Things don't have to be fancy or expensive to work. If you want to make the jars more attractive use some mod podge and a few pieces of decorative tissue paper, material, or a printed picture or patterns that you like, to decorate your jar, or even color code them then stick the labels on. Spray paint is another option. Cling wrap can be used in place of mod podge but you have to use a heat source like a mini heat press to make the cling wrap melt to the jar. Put your cling wrap on the jar, one layer is enough, cut it to the size you need, cut your paper, cloth, whatever material, measure and cut it to the size you need. Put it over the cling wrap, put unwaxed parchment paper over the whole thing and use your mini heat press to go over the whole thing. Go over it until the cling wrap has melted gluing your medium to the jar. Remove your parchment paper paper Walah, you have yourself a decorated storage jar. You can add other touches like buttons, ribbons stickers, etc. I give this Tryptophan 5 stars for; effectiveness, no added ingredients, and value for money.
Review: Well heres the truth about this substance from a science nerd. - I know most things on these pages seem like its full of deception and products that seem fishy. I have only been taking L~TRYPTO for a few days now and i am at the moment feeling pretty calm, aswell as happy. I got this substance to help support the serotonin levels as well as melatonin production that is made from serotonin. Its a chain organic chem that moves as L~TRYPTO via converted to serotonin and when serotonin is needed.. It then turn into melatonin via other bodily chem reactions to support your sleep. Personally i spend thousands of dollars on organic supplements for the reason i am healing my CELIAC. I had a gotten to a severe case of the higher form of CELIAC known as {LEAKY GUT} back in 2013. Where i was allergic to almost everything and i have found a way to cleanse it into healing via researching on medicinal herbs and new pure grade supplements that mimic the body's natural rhythm without any pill materials or added factors like fillers. From advice i say i can't take MELATONIN right? Most CELIACS don't know that MELATONIN will make your immune system over sensitive and when you have a reaction to some allergen. Your reactions are 10 folds over. Trust me i know and having the hives is horrible with all the depression, fatigue, blistering, headaches, stomach pains, hair falling off, wrinkles, nausea, diarrhea, and moodiness. Well i found a solution and that's TRYPTOPHAN. Since this substance is just the organic starter chem. It won't bother if you got a immune system compromise or if you're suffering from anything via inflammation. The substance will provide fuel for serotonin conversion to elevate mood and conversion to MELATONIN to regulate sleep without any contradictions. So you ask have i had any positive effects with it alone. Yes i have with other forms of L~TRYPTO, but what i love about this company called BULK SUPPLEMENTS is that its pure grade in its purest that i'm hooked on. Has a very fast acting and reactive time frame with no side effects. I had recently bought SPIRULINA some time back from them and lets say within two months my hair got thicker, my skin had a change with a glow, i was sleeping way better too, i had a good balance on my mental state, and i did have to stop it due to its effect on my immune system. After i did a research on myself where i keep analytical notes. Yes spirulina does cause the immune system to get sensitive too, but because of the pure form from this company. My body was converting the nutrients and amino acids faster into healing than my inflammation could keep up. Where i healed the wrinkles on my face from all the hive breakouts i had damage from. There currently gone. My experiences and perspectives come from a lot of years of studying certain fields and i'm very ocd and analytic about everything like even the last color on my walls. I read like an addiction. I was studying my grandmas medicine book from age 5. Been an honor student in science for a long time now. I Am currently a Game Design student going for my masters in 3D digital art. I Am a former medical student of dental who had to at one point drop out of my DMD and bachelors in dental. Since i had been dealing with alot of symptoms with my CELIAC from years back with tons of depression. I'm an experienced PSYCHIC with a lot of years of study upon my abilities and the field of hypnosis. I'm even a computer repairman on the side to make some more money when i'm bored. With all my qualifications now in my later 20s. From my experience and point of view as has become profound when understanding methods of operations from practice. I plainly state this.. I give this company {BULK SUPPLEMENTS} 5 STARS and an A++. I went from 3 weeks of inflammation to 3 days of inflammation. Though if i hadn't eaten the wrong thing on some occasions, but i watch out alot too. My recoveries are fast now. Even my stomach has healed to the point i am currently eating more foods. Just not wheat of course. Though i can tolerate milk finally. I have since March 29, 2013 been buying certain pure grade items from there list. I am a very happy and satisfied customer of theirs. This company has QUALITY PRODUCTS, GOOD CUSTOMER SUPPORT, and a very WIDE VARIETY OF PRODUCTS to choose for health and exercise. Have a great day everyone!

Drink this an hour before bed, an hour later, you will feel drowsy and fall asleep easily. I ate 1/2 tsp to get this effect. It doesn't taste great and taste really bad if you eat more than 1/2 tsp.
