Key Ingredients of Isotonix® L-Tryptophan:L-Tryptophan (Tryptopure): 500 mg is an essential amino acid that promotes the normal synthesis and structure of proteins. In the body, L-tryptophan is converted into niacin (vitamin B3) and serotonin, a neurotransmitter which promotes the bodys ability to regulate anger, aggression, mood and sleep. By supplementing with Isotonix L-Tryptophan , serotonin production can be supported, which will promote sleep and enhance mood.* The metabolism of L-tryptophan to serotonin is supported in large part by the following vitamins: Vitamin C: 75 mg is a water-soluble vitamin which acts as an antioxidant, supports normal growth and repair of body tissues, supports cardiovascular health, protects against free radicals and supports cognitive health and performance. Vitamin C supports the hydroxylation of L-tryptophan to serotonin.* Niacin (Vitamin B3): 20 mg plays an essential role as a coenzyme (NAPH/ NADPH) for about 200 enzymes which promote normal tissue respiration, synthesis of fatty acids and steroid hormones, the metabolism of carbohydrates and amino acids, and the transport of hydrogen. When niacin levels are low, the body can use L-tryptophan to manufacture the vitamin. To produce 1 mg of niacin, the body must use 60 mg of L-tryptophan, a process which can rapidly deplete L-tryptophan levels. When niacin levels are sufficient, L-tryptophan can be used for other needs such as retaining healthy levels of serotonin.* Pyridoxine HCl (Vitamin B6): 6 mg promotes the normal conduction of nerve impulses, regulation of steroid hormones, catabolism of glycogen for glucose, heme synthesis, and the synthesis/metabolism of amino acids and neurotransmitters. After conversion to pyridoxal phosphate ( PLP ), vitamin B6 acts as a cofactor for many enzymatic reactions involving L-tryptophan, including L-tryptophans conversion to serotonin.*

Amazing product!!! I have trouble winding down to get to sleep. Always a good night sleep after I drink Isotonix L Tryptophan 😊👍
Works Great for Anxiety/Depression
Take it every night. Helps me sleep, relax, and keep my mood balanced. Can't go with out it!!!
Great for Helping with Stress!
After taking L-Tryptophan everyday for two months, I have noticed a difference in my mood. I am certainly more relaxed & I'm not as quick to jump the gun, so to speak. I recommend this for anyone who has trouble sleeping or is a light sleeper like myself! I noticed that when I did take this before bed, I wouldn't be tossing and turning as much. I had a deeper quality of sleep & actually felt refreshed & ready to tackle the day in the morning! L-Tryptophan has helped me out tremendously!
Love this stuff!!!
I have a big problem falling asleep and I resorted to taking wine before going to bed. My belly grew double the size after a week!. Didn't wanna take sleeping pills because of possible suicidal ideation as a side effect I take this product and after half an hour i start feeling the sleepy. Another great thing about it is that I feel more focused and sharp at work.
Works great to help me fall asleep.
I have found that taking this product 30 minutes before retiring, has helped me to fall asleep fast and to rest much longer at night.
