Seluna Ingredient Research

Evidence-based formulations for perimenopause symptom support

Our Formulation Philosophy

Every ingredient in the Seluna bundle was selected based on:

What makes Seluna different: Most supplement brands hide behind "proprietary blends" or use doses far below what studies show works. We publish every milligram. Our red clover is dosed at the 80mg threshold shown in meta-analyses to produce clinically significant hot flash reduction. Our ashwagandha follows the 600mg/day protocol used in peri-menopause RCTs — with a cycling schedule to maintain effectiveness. This isn't marketing. It's just what the research says.

The Foundation Bottle

A daily blend of two ingredients for continuous hormonal and sleep support.

Magnesium Glycinate

What it is: A chelated form of magnesium bound to glycine, an amino acid. This form has superior absorption compared to magnesium oxide and is less likely to cause digestive upset.

Seluna dose: 250mg elemental magnesium per day (125mg per capsule, 2 capsules)

Why it's in the bundle:

Efficacy of magnesium supplementation on insomnia in elderly
Abbasi et al., 2012 — Journal of Research in Medical Sciences

RCT of 46 elderly adults showed magnesium supplementation (500mg/day) significantly improved sleep time, sleep efficiency, and insomnia severity scores compared to placebo.

Red Clover Isoflavones

What it is: A plant extract containing four primary isoflavones — formononetin, biochanin A, genistein, and daidzein — that have weak estrogen-like effects (phytoestrogens). Red clover is unique among phytoestrogen sources because it contains all four major isoflavones, whereas soy primarily contains genistein and daidzein.

Seluna dose: 80mg total isoflavones per day (40mg per capsule, 2 capsules), standardized to aglycone equivalents

Why the exact dose matters:

Effects of a standardised extract of Trifolium pratense at 80mg/day: systematic review and meta-analysis
Phytomedicine, 2017 — 5 RCTs included

Meta-analysis of red clover isoflavones at 80mg/day showed a statistically and clinically significant reduction in hot flush frequency: weighted mean difference 3.63 hot flushes per day (95% CI: 2.70–4.56; p<0.00001) compared to placebo. The 80mg dose was specifically highlighted as the threshold for clinical relevance.

Red clover isoflavones in the treatment of menopausal hot flushes: meta-analysis
Kanadys et al., Nutrients 2021 — 8 RCTs, 10 comparisons

Meta-analysis of all comparisons showed a statistically significant reduction of 1.73 hot flashes per day vs. placebo (95% CI: -3.28 to -0.18; p=0.029). The effect was larger at ≥80mg/day (WMD -2.80 HFs/d) and in women with ≥5 hot flashes per day at baseline (WMD -2.68 HFs/d; p=0.0105).

Red clover isoflavone supplementation vs. vasomotor symptoms (crossover RCT)
Lipovac et al., 2011 — 109 postmenopausal women, 90 days

RCT showed 80mg red clover isoflavones produced a 73.5% reduction in daily hot flush/night sweat frequency, a 72.2% reduction in night sweats, and a 75.4% reduction in overall menopausal intensity (Kupperman Index) — all significantly greater than placebo. After washout and placebo phases, symptoms returned, confirming the active compound's effect.

Promensil 80mg isoflavones vs. placebo for hot flushes
van de Weijer & Barentsen, Maturitas 2002 — 30 women, 12 weeks

Double-blind RCT in women with >5 hot flushes per day showed 44% reduction in hot flushes in the 80mg isoflavone group vs. no further reduction in placebo (P<0.01). Greene Climacteric Scale score decreased 13% in the active group. First 4-week placebo run-in saw 16% reduction (placebo effect), but the active treatment produced additional significant benefit.
