Pros and cons

Sleep Gummies (Blackberry Zen)

  • 3 mg melatonin per serving, within the range sleep experts commonly suggest
  • Listed in NSF's certified dietary supplement database for label accuracy and contaminants
  • Every ingredient amount disclosed, with no proprietary blend
  • Buyers and TikTok reviewers consistently praise the blackberry flavor and easy chew
  • L-theanine (50 mg) and botanicals (16-17 mg each) are far below studied doses
  • About $0.56 per serving at the brand's list price, roughly five times a basic melatonin tablet
  • Some buyers report nausea or headaches, and buyers are split on value for money
  • Contains gelatin and 2 g added sugar per serving

L-Theanine 200 mg with Suntheanine

  • 200 mg Suntheanine per softgel, matching the dose used in a 2019 randomized trial
  • Single active ingredient with a short, fully disclosed label
  • Third-party tested, cGMP-compliant, gluten-free and IGEN Non-GMO tested
  • About $0.33 per serving at list price
  • Gelatin softgel is not suitable for vegetarians; label lists coconut as a tree-nut allergen
  • Some buyers report stomach upset, and the softgels are on the larger side
  • No NSF, USP or similar product certification
  • Effects are subtle; 200 mg is at the low end of the dose range linked to better sleep

Our verdicts

Sleep Gummies (Blackberry Zen)

OLLY Sleep is a well-made, third-party certified melatonin gummy with a reasonable 3 mg dose, and most buyers find it pleasant and effective. The L-theanine and herbal extracts are too small to add much, so you are mainly paying for melatonin in a tasty, convenient form at several times the price of a basic tablet.

Full review

L-Theanine 200 mg with Suntheanine

This is an easy recommendation for anyone who wants to try L-theanine: a studied dose of a branded ingredient, a transparent label and consistently strong buyer feedback. Expect subtle calm rather than a knockout effect, and choose a capsule version if you avoid gelatin or coconut.
