CBD-Melatonin Compound Improved Sleep, Anxiety, and Pain in Small Pilot Study
A sublingual compound combining 2.5 mg CBD and 1.5 mg melatonin improved sleep quality, reduced anxiety and mood disturbances, and decreased pain over 3 months in 20 patients with sleep disorders.
Quick Facts
What This Study Found
PSQI (sleep quality) and HAM-A (anxiety) scores showed significant improvements. Mood alterations including anxiety, panic, paranoia, and depression were significantly reduced (p<0.03). Pain perception was significantly reduced (p<0.02). Patients reported good general health perceptions.
Key Numbers
20 patients, ages 43-96. Dose: 2.5 mg CBD + 1.5 mg melatonin, 20 sublingual drops. Duration: 3 months. Mood improvements: p<0.03. Pain improvements: p<0.02.
How They Did This
Open-label observational study of 20 patients (ages 43-96) with sleep disorders who took 20 sublingual drops of a CBD-melatonin compound nightly for 3 months. Assessed monthly via direct contact. Used PSQI for sleep and HAM-A for anxiety.
Why This Research Matters
Sleep disorders are extremely common, and many patients seek natural alternatives to prescription sleep medications. If a low-dose CBD-melatonin combination can improve sleep with fewer side effects, it could offer an accessible option.
The Bigger Picture
This is a very preliminary study, but the combination of CBD and melatonin targets multiple sleep-disrupting mechanisms (anxiety, pain, circadian rhythm) simultaneously. The extremely low CBD dose (2.5 mg) is noteworthy, as most CBD studies use much higher doses.
What This Study Doesn't Tell Us
Very small sample (20 patients), open-label design with no placebo control, and described by the authors as "anecdotal" and "compassionate use." The observed improvements could be due to placebo effect, natural improvement, or melatonin alone. No way to separate the effects of CBD from melatonin.
Questions This Raises
- ?Is 2.5 mg CBD enough to produce meaningful pharmacological effects, or is melatonin doing the heavy lifting?
- ?Would a placebo-controlled trial confirm these findings?
- ?How does this combination compare to melatonin alone or CBD alone?

What do these levels mean? →Frequently Asked Questions
Does CBD help with sleep?
This pilot study found improvements when CBD was combined with melatonin, but without a control group, it is impossible to know whether CBD added benefit beyond melatonin alone. The CBD dose (2.5 mg) was very low compared to most CBD studies.
Is the CBD-melatonin combination safe?
No adverse effects were reported in this small 3-month study. However, with only 20 participants and no formal safety monitoring beyond monthly check-ins, the safety profile needs more rigorous evaluation.
