Fenugreek linked to better postpartum sleep scores

Sleep in the first weeks after a first baby is disrupted by physiological change, mood shifts and round-the-clock caregiving, and the resulting fatigue is one of the most commonly reported postpartum complaints. Conventional sedative medications carry side-effect concerns that many new mothers, particularly those breastfeeding, would rather avoid, which is why herbal options attract interest. Fenugreek is already widely used in the postpartum period in some settings, but whether it does anything measurable for sleep quality had not been tested in a properly blinded trial.

This was a two-group, triple-blind randomised controlled trial run in 2023 among 60 primiparous women attending health centres in Sabzevar, Iran. Participants took either a 700 mg fenugreek seed extract capsule or a matched 700 mg placebo containing Avicel powder, once daily, beginning on postpartum day 3, 4 or 5 and continuing to day 60. Sleep quality was assessed with the Pittsburgh Sleep Quality Index before the intervention and again on postpartum days 15, 30 and 60, where lower scores indicate better sleep.

The groups were not equivalent at the start: mean sleep scores were 12.7 in the fenugreek group and 11.3 in the placebo group, a statistically significant gap. At day 15 there was no significant difference between groups. By day 30 mean scores were 8.1 with fenugreek versus 10.0 with placebo, and by day 60 they were 5.1 versus 8.9, both significantly favouring fenugreek. Analysis of covariance adjusting for the baseline imbalance confirmed significant between-group differences at days 30 and 60.

This adds a blinded, placebo-controlled test to a herbal remedy that has largely been used on tradition rather than trial evidence, and the direction of effect is consistent across two of the three follow-up points. The baseline imbalance complicates interpretation, because the group that started worse improved most, a pattern that statistical adjustment can reduce but not eliminate. Everything rests on a questionnaire, so it is unclear whether actual sleep continuity, latency or duration changed. Replication in larger samples with actigraphy or polysomnography is the obvious next step.

This is a reason to think a common herbal capsule may be worth studying properly for postpartum sleep, not evidence that it reliably works. The result comes from one small trial in a single Iranian setting with unequal groups at the outset and self-reported outcomes throughout, all of which limit how far it travels. Anything taken during the postpartum period, herbal included, sits alongside breastfeeding and recovery considerations that a trial of this size cannot speak to.
