Luteal phase & progesterone support
One of 5 mechanistic pathways to 🌸 Female hormonal balance · 11 options
Progesterone dominates the second half of the cycle. When it is low relative to estrogen you get PMS, breast tenderness, spotting, anxiety and broken sleep — because progesterone's metabolite allopregnanolone is a positive GABA-A modulator. Losing it is genuinely losing an anxiolytic.
Timing is the whole test. Progesterone must be drawn around day 21 of a 28-day cycle — roughly seven days after ovulation — and a draw at the wrong point is worse than no draw, because it reads as normal.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
🧬 Vitex (Chasteberry)
Acts on pituitary dopamine receptors to lower prolactin, which permits normal luteal progesterone. The best-evidenced botanical for PMS and luteal-phase defect, with multiple RCTs. Takes about three cycles.
🧬 Vitamin B6 (P5P)
Cofactor for progesterone synthesis and for neurotransmitter production. Meta-analysis supports it for PMS symptoms, especially the mood component.
🧬 Magnesium
Reduces PMS symptoms in trials, particularly fluid retention and mood. Frequently low in this population.
🧬 Evening Primrose Oil
GLA converts to prostaglandin E1, which modulates the tissue response to prolactin. Best evidence is specifically for cyclical breast pain.
🧬 Borage Oil
A more concentrated GLA source; same mechanism.
🧬 Dong Quai
Traditional cycle-regulating herb, usually used in formula rather than alone. Anticoagulant activity is a real interaction concern.
🧬 Wild Yam
Contains diosgenin, which is a laboratory precursor for progesterone synthesis — the human body cannot perform that conversion. The topical progesterone claim is a misunderstanding of industrial chemistry.
🧬 Ovarian & Hormone Support
Formulated blend targeting cycle regularity.
🧬 Zinc
Required for ovulation and follicular development; low zinc is associated with anovulatory cycles.
🧬 L-Theanine
Covers the GABAergic gap in the luteal phase without a hormone.
🧬 Saffron
An RCT showed significant reduction in PMS symptoms and premenstrual mood disturbance.

11 options are mapped to this pathway in the Vault, including Vitex (Chasteberry), Vitamin B6 (P5P), Magnesium, Evening Primrose Oil. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 7 carry clinical validation and 4 are mechanistic predictions.
Timing is the whole test. Progesterone must be drawn around day 21 of a 28-day cycle — roughly seven days after ovulation — and a draw at the wrong point is worse than no draw, because it reads as normal. The markers worth checking are Progesterone, Estradiol, Standard (ECLIA), Prolactin, TSH (Thyroid-Stimulating Hormone).
Unproven is not the same as ineffective. Of the 11 options on this pathway, 7 have clinical validation and 4 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
