L-Tryptophan is an essential amino acid that the body converts into serotonin and melatonin, making it a popular choice for those struggling with occasional sleeplessness or stress. This product is especially suited for adults seeking a clean, non-GMO supplement without unnecessary additives.
The standout feature is the inclusion of BioPerine, a patented black pepper extract that enhances nutrient absorption. Each capsule provides 500mg of L-Tryptophan paired with 5mg of BioPerine, ensuring your body gets the most out of each dose. With 120 capsules per bottle, you get a generous 120 day supply if taken as directed, offering excellent value for the price.

Buying Guide
Dosage and Potency
When choosing a sleep or relaxation supplement, the amount of active ingredient per serving matters. Nutricost L-Tryptophan delivers 500mg per capsule plus 5mg of BioPerine, a black pepper extract that may enhance absorption. This is a solid dose for supporting serotonin and melatonin production. The L-Theanine 200mg capsule provides a moderate amount of this calming amino acid, often used to reduce stress without drowsiness.
Consider your specific needs: if you want a higher dose for sleep onset, the L-Tryptophan is more potent. For gentle daytime calm, the L-Theanine is a good choice. For more on similar supplements, see our double wood magnesium glycinate review for another sleep-support option.
Purity and Quality Standards
Both Nutricost products are made in a GMP compliant, FDA registered facility. The L-Tryptophan is non-GMO and gluten free, while the L-Theanine is also non-GMO and third-party verified. These certifications give you confidence that you are getting a clean supplement without unnecessary fillers. We always recommend looking for such quality marks when buying amino acids.

Servings and Value
The L-Tryptophan bottle contains 120 capsules, providing a 120-day supply if you take one per day. That is excellent long-term value. The L-Theanine comes with 30 capsules, a smaller quantity suitable for trying it out or for occasional use. Think about how often you plan to take the supplement. A larger bottle like the L-Tryptophan is more economical for daily use.
For another high-serving option, consider Double Wood Apigenin, which also offers a generous bottle size.
Intended Use and Timing
L-Tryptophan is best taken on an empty stomach about 30 to 60 minutes before bed to support sleep. L-Theanine can be taken during the day for stress relief or at night to promote relaxation without sedation. Choose based on your schedule. If you want a single product for both purposes, you might combine them, but consult a healthcare professional first.

Is Nutricost L-Tryptophan safe for long-term use?
L-Tryptophan is generally safe when taken as directed. Nutricost’s product is made in a GMP compliant facility and is third-party verified. However, long-term use should be discussed with a healthcare provider, especially if you take antidepressants or have medical conditions.
What is the difference between L-Tryptophan and 5-HTP?
