Diet tweaks may ease menopausal mood dips, but which ones is unclear

Depression and anxiety can significantly affect women during the menopausal transition, a period when mood symptoms often intensify. The established options are hormone therapy, antidepressants and psychotherapy, but nutritional interventions, from whole diets to supplements and nutraceuticals, have been increasingly studied as an additional route. Despite that growing interest, there has been no consensus about whether nutrition genuinely helps mood in this population. This review set out to pool the placebo-controlled evidence and put a number on the effect.

The authors searched PubMed, Cochrane and Embase for articles indexed up to 31 January 2021, looking for randomised placebo-controlled trials of diet, food supplements and nutraceuticals on depressive and anxiety symptoms in women in the menopausal transition or menopausal years. Thirty-two studies were included: 15 measured depressive symptoms, one measured anxiety, and 16 measured both. Two studies combined nutrition with other elements, one pairing vitamin D with a lifestyle-based weight-loss programme and another pairing omega 3 with exercise. Results were pooled and a meta-regression explored what predicted the effect.

The pooled effect favoured the nutritional interventions over placebo for both outcomes, with a standardised mean difference of 0.35 for depressive symptoms and 0.74 for anxiety symptoms. There was significant disagreement between studies, which the authors attribute to differing assessment tools for depression and anxiety and the sheer variety of interventions tested. Subgroup analysis found that menopausal status made a statistically significant difference to the effect, while the type and duration of the intervention did not. Older age was the only significant predictor of effect size in the meta-regression.

This pooling supports the idea that nutrition is a promising tool for managing mood and anxiety symptoms around menopause, adding weight to a scattered literature. But it also shows why no consensus exists: the trials tested very different things and measured them differently, so the average effect cannot be pinned to any specific diet or supplement. The risk of bias among studies further limits confidence. The open question is which specific interventions drive the benefit, and whether they hold up in larger, better standardised trials.

If you are navigating mood changes around menopause, this is a reason to think nutrition may play a genuine supporting role alongside established treatments, rather than being a fringe idea. It is not a reason to buy any particular supplement, because the pooled benefit cannot be traced to one intervention, and the authors themselves say the actual effect of different approaches is still unclear. The finding that menopausal status and age influenced results suggests timing matters in ways researchers do not yet fully understand. Anyone with significant symptoms still has well-established options to discuss with a clinician.
