pcos (polycystic ovarian syndrome) is one of the most common hormonal conditions affecting people with ovaries, yet it remains frustratingly under supported in conventional medicine. many people with pcos are turning to nutrition first approaches to manage their symptoms, and seed cycling is one of the most discussed.
how pcos affects hormones
pcos is characterised by elevated androgens (like testosterone), disrupted oestrogen signalling, and often absent or irregular ovulation. this hormonal environment contributes to symptoms like irregular or missed periods, acne, hair thinning, weight gain, and difficulty conceiving.
where seed cycling fits in
flaxseeds are the most studied seed for pcos relevance. their lignans have been shown to reduce circulating androgens, particularly testosterone, by increasing sex hormone binding globulin (shbg), a protein that binds excess testosterone and makes it inactive. for people with pcos and elevated androgens, this is significant.
pumpkin seeds provide zinc, which is frequently depleted in people with pcos and plays a key role in regulating testosterone and supporting insulin sensitivity, both central concerns in pcos management.
sesame seeds contain sesamin lignans with anti androgenic properties, and sunflower seeds provide selenium and vitamin e, which reduce the oxidative stress that is elevated in pcos.
adapting seed cycling for irregular cycles
if you have pcos and don't have regular periods, you can still practice seed cycling. many practitioners recommend syncing to the lunar cycle as a structural guide when your own cycle is unpredictable. follicular phase runs from new moon to full moon, and luteal phase runs from full moon to new moon.
what to combine it with
seed cycling works best as part of a broader approach to pcos management, alongside a low inflammatory diet, blood sugar regulation, regular movement, and where appropriate, medical support. it's not a cure, but it's a meaningful nutritional tool.
phasebloom's organic seed cycling kit makes pcos supportive seed cycling easy to maintain consistently, which is the most important factor for results.
