For results that last

Good sleep isn't a one-night thing.

Valerian Root is most effective after consistent nightly use over 2–4 weeks. 5-HTP supports serotonin levels that naturally regulate sleep-wake cycles. Magnesium aids muscle relaxation and contributes to normal nervous system function every night. GABA and L-Tryptophan complete the calming blend. For the best results, take your Sleep ZZZ Gummies at the same time each evening. Routine is the secret ingredient.

GABA (Gamma-Aminobutyric Acid) is a natural calming neurotransmitter that helps reduce neural excitability, promoting relaxation and ease of sleep onset.

First proper sleep in ages.

First proper sleep aid that's worked for me. Take two an hour before bed. Don't drive after — they do make you drowsy which is the point. Five ingredients including 5-HTP make this comprehensive rather than just melatonin.

Worth every penny.

Had been struggling with shift work sleep for a year. These have helped me wind down before bed. Valerian and 5-HTP at proper doses, not the homeopathic amounts in other products. Worth every penny.

Fall asleep faster!

Working for me — fall asleep faster, stay asleep longer. Four stars because the blueberry flavour is fine but the gummies are a bit sticky after a few weeks open. Refrigerating helps.

Cherie B. Stockwell · 29 March 2026
I'm out within 45 minutes.

Have tried at least four other sleep products. This is the one. The combination of GABA and magnesium with the valerian is what makes it work. Two gummies and I'm out within 45 minutes.

Patient consistency is the trick.

Used to wake up at 3am and lie there until dawn. These have changed that. Took a couple of weeks to fully kick in, valerian needs time to build up. Patient consistency is the trick.
