SEED CYCLING

The seed cycling chart

Seed cycling is a food habit, not a treatment: two tablespoons of ground seeds a day, swapped at roughly the halfway point of your cycle. It is easy to remember and easy to keep, which is most of why people stick with it. Here is the chart, plus the wider phase food we already teach in the Cycle Kitchen.

Two halves, four seeds

First half — day 1 to ovulation

1 tbsp ground flaxseed + 1 tbsp ground pumpkin seed

Flax brings lignans and soluble fibre; pumpkin seeds bring zinc, magnesium and iron. The traditional claim is that this pairing supports the oestrogen-led first half of the cycle. What is not in dispute: both are nourishing, both are cheap, and both add fibre at the point in the month when appetite is usually steady.

Second half — ovulation to your next period

1 tbsp ground sesame seed + 1 tbsp ground sunflower seed

Sesame carries calcium, zinc and lignans; sunflower seeds carry vitamin E and selenium. The traditional claim is progesterone support through the luteal phase. Practically, these are warm, fatty, satisfying seeds, and the luteal phase is when steady fats and blood-sugar-friendly snacks help most.

Chart: seeds and food by phase

The seed column follows the two halves above. The food columns come from the Cycle Kitchen, where Ayurveda and Chinese Medicine mostly agree on temperature and texture rather than on exact ingredients.

How to actually do it

  • Grind the seeds. Whole flax and sesame mostly pass through undigested; a coffee grinder or a small blender is enough. Grind a few days at a time and keep it in the fridge.
  • Two tablespoons a day, one of each seed. There is no benefit to more, and more fibre than you are used to is uncomfortable.
  • Stir it into something you already eat — porridge, yoghurt, soup, a smoothie, rice at the end of cooking. It should not become a separate ritual you have to remember.
  • Switch on the day you ovulate if you know it, or on day 15 if you do not. Nothing breaks if you are a day or two out.
  • Irregular or absent cycles: many people follow the moon instead — flax and pumpkin from the new moon, sesame and sunflower from the full moon — simply because it gives you a date to switch on.

What the evidence actually says

Be clear-eyed here. There are no good clinical trials showing that seed cycling shifts oestrogen or progesterone, and the hormonal mechanism is inferred rather than demonstrated. What is well supported is that flax, pumpkin, sesame and sunflower seeds are good food: fibre, minerals, and unsaturated fat. If the chart helps you eat more of them and pay attention to your month, that is a real benefit — it just is not a hormonal intervention. Anything that looks like a medical problem, including cycles that are painful, absent or newly irregular, belongs with a clinician.

Common questions

How long before seed cycling does anything?

People who report a difference usually say three to four cycles. Treat that as the point at which you decide whether to keep the habit, not as a promised result.

Do the seeds have to be raw and ground?

Ground, yes — that is how you absorb the oils and lignans. Raw or lightly toasted both work; hard roasting damages the fats.

What if my cycle is not 28 days?

Split at ovulation rather than at day 14. If you do not track ovulation, switch at the midpoint of your own average cycle length.

Can I do this on hormonal birth control?

You can eat the seeds, and they are still good food. There is no cycle of your own to sync them to, so the two-half structure is mostly a rhythm rather than a mechanism.
