Supplement Recommendations for Perimenopausal Anxiety and Insomnia
Based on current clinical practice guidelines, over-the-counter supplements should be used with extreme caution for perimenopausal anxiety and insomnia, as they lack FDA regulation and have inconsistent evidence for efficacy 1. However, when women cannot or will not use hormone therapy, specific supplements show promise based on recent evidence.
Guideline Framework
The AACE guidelines explicitly state that over-the-counter supplements are not regulated by the FDA and have potential for drug interactions and harm (Grade C) 1. Additionally, phytoestrogens including soy-derived isoflavonoids produce inconsistent symptom relief and should be avoided in women with personal or strong family history of hormone-dependent cancers (Grade D) 1.
The Endocrine Society guidelines acknowledge that hormone therapy (not supplements) remains the evidence-based treatment for menopause-associated anxiety, depressive symptoms, and sleep disturbance 2. Supplements are positioned as alternatives only when hormone therapy is contraindicated or refused.
Supplements With Strongest Evidence
Anti-Inflammatory Medicinal Plant Supplements
The most recent high-quality meta-analysis (2025) demonstrates that anti-inflammatory medicinal plant supplements significantly reduce anxiety and insomnia in perimenopausal women 3. This systematic review of 15 studies involving 2,104 healthy perimenopausal women showed:
- Significant improvement in menopause rating scale (MRS) scores
- Specific reduction in anxiety and insomnia symptoms
- Higher response rates compared to comparators
- Network analysis identified response rate as the factor most associated with supplement use
The specific formulations studied included various anti-inflammatory plant compounds, though individual ingredient efficacy varied.
Black Cohosh (Cimicifuga racemosa) Combinations
A 2015 study evaluated a supplement containing Cimicifuga racemosa combined with chasteberry (Vitex agnus-castus), hyaluronic acid, zinc, and ginger 4. Results showed:
- Significant reduction in Kupperman Index scores
- Particularly effective against hot flushes associated with night insomnia and anxiety
- Well-tolerated with no dropouts or side effects
- Effective in both mild and moderate/severe symptom groups
Amberen® Plus Vitamin B Complex
A 2024 randomized, double-blind, placebo-controlled trial of 105 perimenopausal women demonstrated that Amberen® (a succinate-based non-hormonal supplement) combined with Smart B® (vitamin B complex) significantly improved 5:
- Greene Climacteric Scale symptoms
- State-Trait Anxiety Inventory (STAI) scores
- Hospital Anxiety and Depression Scale (HADS) scores
- Sleep quality and cognitive abilities
- Mood and well-being
The intervention was well-tolerated with only mild, transient adverse effects.
Evidence Hierarchy and Limitations
A 2023 meta-analysis examining nutritional interventions found a pooled effect size favoring intervention over placebo for both depressive symptoms (standardized mean difference: -0.35) and anxiety symptoms (standardized mean difference: -0.74) 6. However, significant heterogeneity existed due to:
- Differences in assessment tools
- Variety of nutritional interventions studied
- Menopausal status (perimenopausal vs. postmenopausal)
Older age was the only significant predictor of effect size in meta-regression 6.
Historical Evidence for Specific Compounds
A 2010 systematic review identified passionflower and kava extracts, plus L-lysine/L-arginine combinations, as having strong evidence for treating anxiety symptoms 7. However, this evidence predates the more recent perimenopausal-specific studies and should be considered secondary to the newer data.
Critical Caveats
Regulatory and Safety Concerns
- Supplements are not FDA-regulated, creating quality control and standardization issues 1
- Potential for drug interactions exists
- Individual ingredient doses and combinations vary widely across products
- Most studies show significant heterogeneity, limiting generalizability 6
Research Gaps
A 2026 bibliometric analysis revealed that dietary supplement research during perimenopause has remained limited over the last two decades, with perimenopause notably underrepresented 8. The large number of distinct ingredients (over 80 identified) coupled with limited researcher collaboration suggests dispersed research efforts and few replication studies.
Mechanistic Considerations
A 2026 narrative review highlights that tryptophan and GABA pathway modulation through the gut-brain axis represents a promising mechanistic target 9. Estrogen fluctuations during perimenopause alter gut microbiota composition, affecting tryptophan metabolism and GABA synthesis. However, efficacy in perimenopausal women remains to be established through rigorous clinical trials.
Clinical Algorithm
For perimenopausal women with anxiety and insomnia who refuse or have contraindications to hormone therapy:
First consideration: Anti-inflammatory medicinal plant supplements based on 2025 meta-analysis evidence 3
- Look for formulations with documented anti-inflammatory properties
- Monitor for response over 3 months
Second consideration: Black cohosh-containing combinations (specifically with chasteberry, if available) 4
- Particularly appropriate when night insomnia accompanies hot flushes
- One tablet daily for 3 months
Third consideration: Succinate-based supplements with vitamin B complex 5
- Appropriate for comprehensive symptom management including cognitive symptoms
- Monitor anxiety scales (STAI, HADS) for objective improvement
Avoid:
- Soy-based phytoestrogens in women with hormone-dependent cancer history 1
- Custom compounded "bioidentical" supplements 1
- Products without clear ingredient disclosure or quality certification
Monitor for:
- Drug interactions with concurrent medications
- Lack of response after 3 months (consider alternative approaches)
- Any adverse effects, though generally mild and transient in studies
