Selene · Formulation Reference
→ Cycle ScienceThis document describes the complete decision logic behind every pack. It is intended for clinical advisors, formulators, and regulatory reviewers. All ingredient selections, dose justifications, and future biodata integration plans are documented here.
Each daily pack is assembled by the buildDailyPack() engine in layers. Each layer is gated by subscription tier. Contraindications are evaluated at each step before any item is added.
The 4–5 core ingredients for the current cycle phase. These are clinically validated for every menstruating person regardless of profile. Cap: 4 capsules.
Profile-specific ingredients added. Items that worsen the profile's core pathophysiology are removed from the base stack.
Breastfeeding → iodine + choline. Plant-based → algae DHA replaces fish oil, B12 added. High melanin → D3 boosted.
HRV dip → cortisol buffer. Low sleep score → calm support. Elevated glucose → metabolic support. Temp deviation → phase prediction signal.
Self-reported goals mapped to clinical supplements via GOAL_BOOSTS table. Goals can add items not in any base or profile stack.
User-selected add-on ingredients bypass tier capsule caps. They are checked for contraindications but always included if safe.

strongEach profile is detected from the intake quiz, symptom selection, age, and cycle parameters. The table below shows the complete ingredient stack at each tier, per cycle phase.
High estrogen relative to progesterone — common in the 30s–40s. Drives heavy periods, bloating, breast tenderness, and mood dips in the second half of your cycle.
Short or spotty luteal phase, anxiety that spikes before your period, sleep trouble in the second half of the month. Progesterone is your "calm" hormone — when it's low, everything feels harder.
Irregular cycles, chin or jaw acne, unwanted facial hair, or a PCOS diagnosis. Driven by insulin resistance and excess androgens — the good news is both respond well to targeted nutrition.
PCOS without insulin resistance — normal or low BMI, irregular or absent cycles, and often elevated LH. The driver is hypothalamic dysfunction, not metabolic. Berberine is wrong here: it lowers blood sugar that's already normal and can cause reactive hypoglycemia. Inositol works on FSH signaling independent of insulin sensitivity; spearmint and NAC target androgen excess directly without touching blood sugar.
Cycles getting irregular, hot flashes, sleep disruption, and a mood you don't recognize. Usually starts in the early 40s — your estrogen is fluctuating wildly before it declines for good.
No more cycles, but the work isn't done. Post-menopause is the window for bone building, cardiovascular protection, and cognitive maintenance. Estrogen is low and stable — the stack here protects the systems it used to support.
You're already managing estrogen via prescription — phytoestrogens (red clover, soy isoflavones) add uncontrolled estrogen on top of a calibrated dose and don't belong here. The stack covers the downstream gaps your HRT doesn't: bone mineral density via K2 directing calcium into bone not arteries, cognitive support via phosphatidylserine, and cardiovascular protection via omega-3. Confirm additions with your prescribing physician.
Dry skin, vaginal dryness, low libido, joint aches, or brain fog that doesn't lift. Can happen post-pill, during intense training, or from undereating. Estrogen isn't just a reproductive hormone — it's everywhere.
In the 1–2 weeks before your period, mood, anxiety, or rage become hard to manage — then they lift the moment bleeding starts. PMDD is a neurological sensitivity to progesterone fluctuation, not a character flaw.
Persistent fatigue, hair thinning, cold hands and feet, slow metabolism, or a diagnosed thyroid condition. The thyroid sets the tempo for everything — cycles, weight, mood, and energy all follow its lead.
In Hashimoto's the immune system is attacking the thyroid — the thyroid is the target, not the problem. Selenium (200mcg) reduces anti-TPO antibodies in multiple RCTs and is the most evidence-backed supplement for slowing immune attack. High-dose iodine can trigger flares by increasing antigen presentation; this protocol avoids it. Vitamin D and omega-3 work on immune regulation as much as thyroid function.
Endo tissue outside the uterus drives some of the worst menstrual pain documented — plus chronic pelvic pain, painful sex, and exhaustion. The protocol targets the prostaglandin cascade, estrogen signaling that feeds endo tissue, and the oxidative stress unique to this condition.
Fibroids are estrogen-driven benign tumors that cause heavy bleeding, pressure, and pain. They affect up to 70% of women and are dramatically underaddressed. The protocol targets fibroid cell proliferation, estrogen clearance, and replenishes iron lost through heavy cycles.
The first 2–5 years of menstruation are often irregular, heavy, and painful — not because something is wrong, but because the HPG axis is still calibrating. Gentle support for iron replenishment, bone building, and acne management during peak adolescent development.
Hypothalamic amenorrhea — missing periods from underfueling, overtraining, or chronic stress. The hypothalamus interprets stress as famine and shuts down reproduction. The protocol restores HPA axis balance and replenishes nutrients depleted by high cortisol and low energy availability.
When the body doesn't have enough fuel, the hypothalamus shuts down reproduction first — it's a survival response, not a failure. The missing period is a signal, not the problem. This protocol replenishes the nutrients most depleted by chronic restriction (B vitamins, iron, zinc, folate, vitamin D) and supports the HPA axis without stimulants that can suppress hunger signals. Recovery takes time and pairs best with a registered dietitian.
Birth depletes iron, DHA, zinc, and B vitamins dramatically. Add postpartum thyroid vulnerability, estrogen-crash hair loss, and mood risk — and you have the most nutritionally demanding stretch of a woman's life. The protocol addresses all four simultaneously without crossing into breastfeeding contraindications.
Hormonal birth control depletes B6, B12, folate, zinc, magnesium, and CoQ10 — often significantly. The first 3–6 months off the pill, your body rebuilds depleted cofactors and reactivates ovulation. This stack accelerates the reset and smooths the hormonal volatility of the transition.
Natural conception means optimizing egg quality, cycle regularity, and the uterine environment simultaneously — every month. The protocol front-loads CoQ10 for mitochondrial support in developing follicles, active folate before you know you're pregnant, and zinc for precise ovulation timing.
The 90 days before retrieval determine the eggs collected — the follicles developing now are the ones your clinic will aspirate. This stack maximizes oocyte mitochondrial health, antioxidant protection in follicular fluid, and DNA fidelity in maturing eggs. Once your clinic starts FSH or LH injections, pause all non-prescribed supplements and confirm what to resume post-retrieval with your reproductive endocrinologist.
Your reproductive endocrinologist's protocol is primary — this stack covers only the supplement gaps with strong evidence and minimal interaction risk during IVF treatment. CoQ10 for oocyte mitochondria, methylfolate for DNA repair, vitamin D for implantation success rates, omega-3 for embryo development. Everything else defers to your clinic. Confirm any additions with your REI before starting stimulation.
Your cycle is working. Now make it work for you. This is the performance-first stack for women with regular cycles and no specific diagnosis — built to amplify energy, resilience, and recovery across all four phases.
Built for the woman who trains. Intense exercise depletes iron, creatine, and magnesium faster than average — and your recovery window is compressed by your cycle's hormonal shifts. This stack synchronizes supplement timing with your training load.
Your situation is specific — HRT regimen, transition stage, complex history, or conditions that don't fit a named pattern. A clinical advisor will review your intake and build a pack matched to your actual biochemistry, not a best-guess template.
Self-reported goals in the intake quiz trigger additional ingredients at the Full tier. Goal items are added after the profile stack and are capped by remaining capsule capacity.

The pack engine applies dose scaling based on body weight, age, and wearable biometrics. Fields marked 'planned' are collected at onboarding but not yet applied to dosing.
Body weight (kg)
Iron bisglycinate
Women >75kg may need 30mg vs 25mg to achieve serum ferritin >30 ng/mL. Currently fixed; future: BMI + menstrual loss estimate.
Magnesium glycinate
Therapeutic ceiling ~6mg/kg/day. A 90kg woman can absorb 540mg/day vs 300mg standard. Currently capped at 300mg.
Creatine
Maintenance dose is ~0.03g/kg/day. 3g/day add-on is adequate below 100kg; consider 5g/day for high-mass athletes.
Height / BMI
Vitamin D3
Adipose tissue sequesters D3; BMI >30 may require 2–4× standard dose to reach serum 25(OH)D >40 ng/mL. Currently 2000 IU fixed.
Omega-3 / Algae DHA
Anti-inflammatory effect is dose-dependent on body weight. 1g EPA+DHA is effective at normal weight; 2g warranted above 80kg.
Age
CoQ10
Endogenous synthesis declines ~50% by age 40. Essential tier dose (100mg) should scale to 200–400mg for women 40+. Currently flat.
Calcium
Post-menopausal profile already boosts calcium. Future: continuous taper from baseline ~500mg at 20 → 1000mg at 50+ based on bone remodeling curves.
Collagen
Skin collagen density declines 1%/year after 25. Add-on dose (10g) is standard; no weight/age adjustment needed at this dose.
Wearable — HRV trend (rolling 90-day)
Phosphatidylserine
Currently binary: HRV < 85% baseline → add PS. Future: dose-titrate from 100mg (mild) to 400mg (severe HRV suppression).
Ashwagandha
Combined cortisol/stress signal (HRV + self-report stress) to add ashwagandha as second-line adaptogen when PS alone is insufficient.
Wearable — Sleep architecture
Melatonin
Current: 0.5mg if sleep score < 65. Future: 0.5mg for delayed circadian phase, 1mg for total sleep time < 5h, skip if sleep latency is the only issue.
Magnesium glycinate
Slow-wave sleep deficiency (when provided by device) triggers evening timing emphasis. Currently timing is fixed to evening regardless.
CGM — continuous glucose
Berberine
Currently static threshold (avg glucose > 100). Future: time-in-range <70% or post-meal spikes >160mg/dL trigger dosing regardless of fasting average.
Inositol
Myo-inositol 2g/day reduces post-meal glucose in PCOS even without elevated fasting glucose. Add when CGM shows persistent follicular-phase spikes.
Rationale for weight-based dosing: Most supplement RCT doses are calibrated on 60–70kg study populations. For ingredients with narrow therapeutic windows or steep dose-response curves (magnesium, vitamin D, omega-3, creatine), weight-adjusted dosing improves efficacy and reduces the risk of under-dosing in larger-framed women. Height adds context for lean vs. adipose mass distribution, which affects fat-soluble vitamin absorption (D, K2, omega-3). Implementation requires only BMI or weight at onboarding — no clinical-grade measurement is needed.
Add-ons are user-selected daily boosters that ship alongside the base pack. They bypass tier capsule caps and are always included once subscribed, subject to individual contraindication checks. All are available as standalone subscriptions at any tier.
Daily 3g pouch — brain, strength, and cycle-phase stamina. Women start with ~80% lower stores than men.
Creatine boosts phosphocreatine in both muscle and brain — women start with ~80% lower stores than men, so the cognitive and strength gains from supplementation are proportionally larger.
Ramp: No loading phase needed. 3g/day reaches full saturation in 28 days with no GI impact — this is the clinically preferred protocol.
Daily 2g pouch — insulin sensitivity and ovulation support. Works with or without PCOS.
Insulin sensitizer and FSH amplifier — restores ovulation in PCOS in multiple RCTs.
Ramp: Start at 1g for the first week, then step up to 2g. Full cycle-regulation effect takes 8–12 weeks.
Daily 10g bovine pouch — clinical-dose skin, hair, and joints. Add to morning coffee.
Estrogen supports collagen synthesis — supplementing in follicular phase amplifies the effect. 10g is the clinical dose; capsule form is impractical at this amount.
Ramp: Start at 5g for week 1 if your stomach is sensitive. Skin changes take 6–8 weeks of consistent use to notice.
Vitamin C + silica + lysine — the vegan collagen-building stack, in capsule form.
Supports your body's own collagen synthesis — vitamin C is the essential enzyme cofactor, silica enables cross-linking, lysine provides the substrate. A complete vegan alternative to exogenous peptides.
Ramp: Results build over 8–12 weeks. Works via endogenous synthesis rather than exogenous peptides — the mechanism is different, the outcome is comparable.
Daily 250mg NMN — raises NAD+ for mitochondrial energy, egg quality, and cellular repair. Especially relevant for women 35+.
Raises intracellular NAD+ — the coenzyme that declines sharply with age and during perimenopause. Supports mitochondrial function in oocytes, improving egg quality and energy production.
Ramp: Start at 250mg; may increase to 500mg after 4 weeks. Best taken in the morning (activates SIRT1).
Creatine monohydrate— the most evidence-backed women's supplement not already in the base stack. Women start with ~70–80% lower creatine stores than men (smaller muscle mass + typically lower dietary intake from red meat). 3g/day raises muscle PCr stores by 20–30% and has emerging evidence for luteal-phase mood and cognitive support (see Smith-Ryan 2021, Dolan 2019). No loading phase needed. Safe at all cycle phases.

Ingredient-level contraindications — each ingredient carries a list of conditions/medications that exclude it from the pack. These are checked individually at every pack build.
Profile-level removes — some hormone profiles actively remove ingredients from the base stack because those ingredients worsen the profile's pathophysiology (e.g., vitex is removed in PCOS because it can worsen androgen symptoms).
Hard stops (currently manual)— pregnancy, active cancer treatment, pediatric age (<13), and known hypersensitivity. These are collected during onboarding and result in full pack suspension pending clinical consultation. Not yet automated.
FDA disclaimer — All ingredients are classified as dietary supplements under DSHEA. No ingredient in the Selene formulary has an approved drug claim. Statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.
Saffron + SSRI interaction — Saffron (30mg/day) has mild MAO-inhibiting properties and serotonergic activity. It is contraindicated in the PMDD profile when SSRIs are active due to theoretical serotonin syndrome risk, despite limited clinical evidence at this dose. Conservative exclusion maintained.
Vitex + hormonal BC / IVF — Vitex may interfere with exogenous progestins and is excluded when hormonal birth control is active. It is also excluded during IVF due to unpredictable LH signaling interactions.
Berberine + metformin — Concurrent use may cause additive hypoglycemia. Berberine is excluded from any pack where metformin use is reported.
These ingredients have a plausible mechanism and a positive safety profile but insufficient large-scale human trial data to include in the core formulary. We track the literature and will promote them to active status as evidence matures. In the meantime they appear as optional add-ons for users who want early access.
Our inclusion threshold:≥2 human RCTs, >80 subjects total, no serious adverse signals in safety literature. “Unclear” means the mechanism is sound but effect size or optimal dose remains debated. “No harm” means low-risk to trial while research continues.
