hormones run everything. your energy, your mood, your skin, your sleep, your metabolism, your fertility. all of it is orchestrated by a delicate hormonal rhythm that shifts throughout your menstrual cycle. when that rhythm is disrupted, everything feels off.
seed cycling is a nutrition based approach to supporting that rhythm from the inside.
the two hormones at the centre of your cycle
oestrogen and progesterone take turns leading throughout your cycle. oestrogen dominates the first half (follicular phase), driving energy, motivation, and a sense of wellbeing. progesterone leads the second half (luteal phase), promoting calm, supporting sleep, and preparing the body for menstruation if conception hasn't occurred.
when either hormone is too high or too low, or when they're out of balance with each other, you experience symptoms. low progesterone leads to anxiety, poor sleep, and spotting before your period. excess oestrogen causes bloating, breast tenderness, heavy periods, and weight gain around the hips.
how seed cycling supports balance
follicular phase (days 1 to 14): flaxseeds and pumpkin seeds. flaxseeds contain phytoestrogenic lignans that support healthy oestrogen metabolism. they help the liver process and eliminate excess oestrogen efficiently. pumpkin seeds are rich in zinc, a mineral that supports the production of progesterone in the second phase.
luteal phase (days 15 to 28): sesame seeds and sunflower seeds. sesame seeds provide lignans and zinc that support progesterone. sunflower seeds deliver selenium and vitamin e, both critical for hormone metabolism and reducing the inflammation that worsens hormonal symptoms.
a cumulative practice
seed cycling works cumulatively. you're not taking a supplement that hits your bloodstream immediately. you're giving your body consistent nutritional signals over time. most people notice meaningful changes after two to four cycles.
who it's especially useful for
seed cycling is particularly popular among people coming off hormonal birth control, those managing pcos, individuals in perimenopause, and anyone who experiences cyclical mood or energy changes tied to their period.
phasebloom's organic seed cycling kit makes it straightforward. the seeds are portioned by phase, organic, and ready to add to smoothies, yoghurt, oats, or salads. if hormone balance is your goal, consistent seed cycling is one of the most accessible places to start.
