Review: Quality, and best price point for Tryptophan I've found. - 500 mg improves my sleep when taken before bed. Both falling asleep sooner and deeper more quality sleep., 1000 mg has a bit of sleepiness the next day. So, I know it is working and has quality behind it. I stick to the 500 mg. My psychoactive meds have a secondary serotonin agonist effect already and I eat my daily RDA of protein (where you naturally get it from). So, I am not deficient in tryptophan. As such, I don't see additional mood benefits from it beyond what my meds already do. But, others may find benefit there even if I do not, and may support meds that affect serotonin or can benefit from a potential increase in it.
Review: Excellent quality, you can trust this brand - I like Bulk Supplements. Good quality control and potency for a reasonable price.The dosage is perfect and really helps improve the quality of your sleep. Unfortunately, after several days of use, I developed severe headache and fatigue. I looked through my geneticlifehacks DNA analysis to understand what was happening. I discovered I cannot use Tryptophan because I have 2 homozygous ACMSD mutations which results in a lack of a crucial enzyme. The tryptophan isn't metabolized to seratonin and niacin, it takes an alternate pathway and becomes Quinolinic Acid, a short lived but potent neurotoxin. Long term, it contributes to a prolonged inflammatory response. It's a shame, because I thought I found the solution to my insomnia, but it wasn't meant to be.

### ⭐⭐⭐⭐⭐ Better sleep and calmer days
*by G***E on December 9, 2025*

I’ve been taking L-Tryptophan for a few weeks, and I’ve noticed a real difference in my sleep and overall mood. I fall asleep more easily at night and wake up feeling more rested and refreshed in the morning. I also feel a bit calmer and less stressed during the day, which is a nice bonus. The capsules are easy to swallow, and I haven’t experienced any side effects. It feels like a gentle, natural way to support both sleep and emotional well-being. I would definitely recommend it to anyone looking for a safe supplement to help with sleep and relaxation.
