About this product

The disclosed actives are 50 mg of Griffonia-derived 5-HTP and 10 mg of vitamin B6 in a time-release tablet. That combination may support gradual serotonin-pathway exposure and is less aggressive than a high-strength 5-HTP serving.

The product name references melatonin, but the supplied ingredient list does not include a melatonin amount. Without that information, the full sleep effect, dose suitability, and next-day sedation risk cannot be assessed reliably.

Griffonia standardization is also not stated, and mood or stress support remains secondary to the sleep-oriented format. Interaction screening is essential because 5-HTP can compound serotonin-raising medicines even at a lower amount.

Who is it for
  • People seeking lower-dose time-release 5-HTP for sleep
  • Users who can verify the full melatonin label separately
Best for
  • Gradual overnight 5-HTP delivery
  • A lower starting amount with vitamin B6

Pros

  • Provides a modest 50 mg 5-HTP amount
  • Uses time-release delivery
  • Includes vitamin B6

Cons

  • No melatonin amount is supplied despite the product name
  • Griffonia standardization is absent
  • Full sleep and next-day effects cannot be assessed

Warnings

  • Do not combine 5-HTP with SSRIs, SNRIs, MAO inhibitors, triptans, or other serotonin-raising medicines without medical supervision.
  • The undisclosed melatonin amount prevents a reliable assessment of combined sedation and next-day drowsiness.
  • Time-release 5-HTP may prolong nausea, vivid dreams, or drowsiness if poorly tolerated.

Product analysis

75 out of 100
Time-release 5-HTP and B6 may suit gradual overnight support. The missing melatonin amount in the supplied ingredient data prevents a complete assessment of the named sleep formula.

AI assessment of the formula, label and price. How scoring works

Nutrient quality83

Griffonia simplicifolia is identified as the source, but the plant part and active standardization are not both clear. The 50 mg 5-HTP serving is a cautious starting amount, while the added nutrients provide mixed additional value.

.
Ingredient transparency82

All supplied active ingredients have specific amounts, and no proprietary blend hides key doses. Serving count is available, but full intake directions, excipients, and a serotonin-medication warning are absent from the supplied label details.

.
Customer satisfaction68

The supplied aggregate rating is favorable but not exceptional, and review volume determines how much confidence it deserves. No review text is provided to identify repeated complaints or firsthand experiences tied to the intended uses.

.
Value for money60

Cost efficiency per equivalent active amount appears limited, with the starting-level dose shaping practical value. Vitamin B6 supports conversion pathways, though the disclosed amount is more than needed as a basic cofactor.
