I'm a seasoned iHerb shopper, always on the lookout for top-notch supplements. Let me tell you about NOW Foods L-Tryptophan. With 500 mg per serving and 120 capsules in the bottle, it's a solid buy. I started taking L-Tryptophan to help with my sleep patterns and mood, and it's been a game-changer. It's known to be a precursor for serotonin, and since I've added it to my nightly routine, I've noticed a smoother transition to sleep and more balanced emotions during the day. The veggie capsules are a breeze to take, especially if you're trying to avoid animal products. I also appreciate that NOW Foods is a trusted brand with a reputation for quality. If you're thinking about trying L-Tryptophan for sleep or mood support, this product is a great option. Of course, it's always wise to have a chat with your healthcare provider before starting any new supplement.

A no-fuss amino acid that’s like a cozy blanket for your brain—helps you chill and sleep better. Sleep Savior, takes the edge off nighttime brain chatter. Pop 1–2 capsules before bed, and it nudges melatonin production for deeper Zzz’s . Subtly lifts mood by supporting serotonin (your “happy hormone”)—great for stressy days . For this amount, it’s a solid “emergency chill pill” for sleepless nights or low-key anxiety. Not magic, but reliable.

The quality of Now products is well known and I ordered L-tryptophan from this brand first of all for calm and sleep. I did not need it for muscles or training, diet factor also is not my problem. Falling asleep with two pills was really effective. Did not use it in daytime so cannot tell about the energy it gives. The pills have rather big size and neutral taste. If my sleep will be improved I'll definitely order more. I examined many products with calming effect and Melatonin and Tryptophan are on the top of the list.

I love this supplement, I can't live without it. It helps me sleep deeply without needing synthetic medications.
I’ve been taking this supplement for a few weeks now, and I’m genuinely impressed with the difference it’s made. The quality is outstanding – no fillers, clean ingredients, and easy to take. I started noticing improvements in my energy levels, recovery time after workouts, and even my overall mood within the first two weeks. What I appreciate most is that it doesn’t cause any stomach discomfort, which I’ve experienced with other brands. The capsules are easy to swallow, and the dosage is perfectly balanced. I also like that the company provides clear information about sourcing and testing – it gives me confidence that I’m putting something trustworthy into my body. Overall, I highly recommend this supplement to anyone who’s serious about supporting their health, performance, and daily well-being. It has definitely earned a permanent place in my routine.
Love the quality and dosing here, I don't exceed two capsules per day. the supplement helps my mood, and helps with impulse eating. I feel better overall when taking this. I feel like I have more control over my actions etc.. I recommend this supplement.
I’ve been taking NOW Foods L-Tryptophan (500 mg) hoping it would help with sleep and mood, but unfortunately, I haven’t noticed any real improvement in either my sleep quality or behavior. It’s a decent product and well tolerated, but for me, it just didn’t deliver the benefits I was looking for.
