Effect of a nutraceutical combination on sleep quality among people with impaired sleep: a randomised, placebo-controlled trial

This study evaluated the effects of a nutraceutical blend (l-theanine, lemon balm, valerian, and saffron) on sleep quality in adults with sleep impairments using a randomized, placebo-controlled design. Both the treatment and placebo groups improved in sleep quality and other related measures, but differences between groups were statistically insignificant. Behavioral and placebo effects likely influenced the outcomes. This suggests that while the nutraceuticals are safe, their specific efficacy over placebo for sleep improvement is unclear.

Improving sleep may be better achieved through behavioral strategies like maintaining a consistent bedtime, reducing screen exposure, and practicing relaxation techniques. While the studied nutraceutical is safe, its specific benefit over placebo remains uncertain. A balanced approach combining lifestyle changes with professional advice may offer the best results.
