Positive experiences
“L-Tryptophan has given me the most relaxation / anti-anxiety out of the aminos I've tried.”
“L-tryptophan has been a game changer for my seasonal depression... Whenever I start to get that feeling of 'what's the point' I pop 2 of ND's L-tryptophan and feel so much better.”
“L-tryptophan makes me sleep deeper, and I wake up feeling more content.”
“I am currently taking a nighttime stack to help me sleep: L-Tryptophan, Chelated Magnesium, Valerian & Magnolia Bark. This is helping me get through the night with minimal discomfort.”
“I am taking ZMA, 1000 mg L-Tryptophan and 250mcg Melatonin and that seems to improve my sleep quality considerably.”
“5 L-tryptophan 500mg each... This has been an amazing sleep stack for me.”
Negative and mixed experiences
“No need for tyrosine and tryptophan if you have basically any protein in your diet. They are only useful if you are on a fast. I have taken both and they do nothing apart from wasting money.”
“I've felt like I'm on a microdose of LSD that's slightly too large lol. I feel that unique uncomfortable feeling where my atoms feel like they're vibrating a bit too quickly.”
“I took L-Tryptophan in the past and that stuff made me feel really groggy in the morning.”
“I just started taking it at nights for sleep ... it's really a potent knock out type supplement.”
“It doesn't do anything for me... Tried 50-150mg with ECGC as decarboxylase inhibitor, but nothing.”
