Score Summary

Known Nutrition Sleep Better scores 76/100 vs Keka Naturals Sleep Support at 66.0/100. Known Nutrition Sleep Better wins on effectiveness, ingredient quality, certifications. Keka Naturals Sleep Support is stronger on value for money and side effects.

Known Nutrition Sleep Better vs Keka Naturals Sleep Support: What Does the Data Say?

Known Nutrition's Sleep Better Vegan Gummies score 76/100 at £9.74. The formula contains 90mg saffron (3:1), 300mg lemon balm (10:1), and 150mg chamomile (5:1) — all matched to research doses. Keka Naturals' Sleep Support scores 66/100 at £15.95, using 5-HTP, valerian root, magnesium and B6 in capsule form. A offers herbal ingredients that dissolve easily; B works via serotonin support instead.

Pick A if you're starting out with sleep aids. Reviews show strong repeat-purchase rates, and Known Nutrition backs this with ISO, GMP and BRC certification plus independent testing. Choose B if you prefer capsules or specifically respond to 5-HTP, or if you're over 40 with mainly sleep maintenance issues. B users report gentle relaxation without morning grogginess.

A's downside: polyol sweeteners (maltitol, sorbitol, erythritol) can cause stomach cramps or bloating in sensitive people. There's no melatonin for direct sleep-onset support. B lacks third-party testing, so purity is unverified. A handful of B users reported zero improvement, making A the more reliable choice.

Sleep Better Vegan Gummies with Saffron

Pros

  • ✓Strong repeat-purchase pattern and 5-star majority — multiple reviewers on their 2nd or 3rd order report sustained benefit
  • ✓Well-dosed herbal stack: 90mg saffron (3:1), 300mg lemon balm (10:1), and 150mg chamomile (5:1) meet or exceed doses used in sleep/anxiety research
  • ✓ISO, GMP and BRC certified with independent third-party testing — meaningful quality assurance for a supplement brand
  • ✓Vegan, allergen-free, no artificial colours or preservatives — broad dietary compatibility

Cons

  • ✗Multiple polyol sweeteners (maltitol, sorbitol, erythritol) can cause bloating or stomach cramps in sensitive individuals — reported by at least 2 reviewers
  • ✗No melatonin in the formula, which limits direct sleep-onset support compared to many UK competitors
  • ✗Vitamin B6 at 0.7mg (50% NRV) is a minor contributor — unlikely to drive meaningful effect on its own
  • ✗Inconsistent results: a notable minority of users report no improvement even after several weeks of consistent use

Best For

Adults with mild-to-moderate sleep-onset difficulties People whose sleep is disrupted by anxiety or stress New parents or shift workers with irregular sleep patterns Vegans and vegetarians seeking an allergen-free sleep aid Those who prefer gummies over capsules or tablets

  • ✗Ineffective for a subset of users (2 reviewers reported zero sleep improvement)
  • ✗Ingredient doses not fully disclosed (valerian root dose unclear from listing)
  • ✗No melatonin — some users needing stronger sleep onset support may find the formula insufficient

Best For

Adults over 40 with mild-to-moderate sleep maintenance issues People seeking a non-melatonin, plant-based sleep supplement Those sensitive to heavy sedatives wanting a gentle wind-down aid Vegans and individuals with common dietary restrictions
