Solgar Griffonia 5-HTP Complex vs Keka Naturals Sleep Support: What Does the Data Say?
Both products score identically at 66/100, but they take quite different approaches to sleep support. Solgar's Griffonia 5-HTP Complex is a focused, two-ingredient formula — 5-HTP paired with vitamin B6 in its more bioavailable pyridoxal-5'-phosphate form alongside standard pyridoxine HCl. Keka Naturals takes a broader approach, combining 5-HTP and B6 with valerian root and magnesium to address sleep from multiple angles. Solgar comes in a pack of 30 at £13.72, which works out expensive for daily use; Keka offers 60 capsules for £15.95, scoring significantly better on value at 73/100 versus Solgar's 55/100.
Solgar is the better pick if your sleep problems stem from mood, anxiety, or hormonal disruption — reviewers report meaningful improvements in depression and anxiety symptoms, and it has a strong reputation among perimenopausal women. The premium B6 form is a genuine differentiator for those who absorb standard pyridoxine poorly. Keka makes more sense if you simply want help switching off at night without targeting mood specifically — the valerian and magnesium combination helps with physical relaxation, and users consistently report falling asleep faster without morning grogginess. Its effectiveness score is lower at 65/100 versus Solgar's 72/100, but for a straightforward wind-down supplement at half the per-capsule cost, it represents better everyday value. Solgar's longer track record gives it a slight edge on trust there. Both are vegetable capsules, so suitable for vegetarians. If you're on SSRIs or MAOIs, avoid both — 5-HTP carries genuine interaction risks with serotonergic drugs.
