Known Nutrition Sleep Better vs Solgar Griffonia 5-HTP Complex

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

Pros

• ✓Strong mood and sleep improvement reported by majority of reviewers, including for depression and anxiety
• ✓Reputable, long-established brand with consistent quality standards
• ✓Premium B6 forms used (pyridoxal-5'-phosphate alongside pyridoxine HCl) for better bioavailability
• ✓Vegan, gluten-free, dairy-free and soya-free — broad dietary compatibility

Cons

• ✗Only 30 capsules per pack — expensive and inconvenient for daily long-term use
• ✗Not independently third-party tested (NSF, Informed Sport, etc.)
• ✗One report of severe depression potentially linked to valerian interaction
• ✗Magnesium oxide included alongside bisglycinate — oxide is poorly absorbed and may cause GI upset
