8 minute read

Creamy, luscious and oh-so decadent, these “peanut butter” seed cycling cups are the tastiest way to support your hormones, naturally! As a Nutritional Therapy Practitioner,, I am always doing what I can to support my body in more holistic and natural ways and seed cycling is one of them. When I was dealing with a lot of the symptoms of my Hashimoto’s, my cycles became very very short and I dealt with a lot of PMS symptoms like acne, mood swings, irritability, fatigue, sleeplessness, and cramping.

Within the first month of starting seed cycling, my cycle went from 20 days to 27, and all of my PMS symptoms either completely disappeared or drastically lessened, I couldn’t believe it! Now, it has been several months and I have to say, I will continue doing this for the rest of my life as all of my symptoms have gone away and my cycles so much more balanced. These amazing and delicious seed cycling butter cups make it so tasty and easy to start seed cycling today!

What is Seed Cycling

Seed cycling is a natural way using whole foods to support the delicate balance of a woman’s hormones.  When this balance becomes off balance due to diet, environmental toxins, lack of sleep, stress, exercise, medications, or illness it can lead to an array of chronic symptoms such as PMS, headaches, irregular menstrual cycles, PCOS, acne and more. 

One of the easiest and most natural ways you can support your body’s reproductive hormones is with seed cycling.  As I have told many clients, your body is this amazing machine that has the ability to restore and heal when given what it needs.  So let’s dive into seed cycling some more!

How does Seed Cycling work to Balance Hormones in the Luteal Phase

The luteal phase of a woman’s cycle begins after ovulation has occurred and is typically during days 15-28.  During this phase, the corpus luteum begins to release progesterone, a sex hormone that supports the thickening of the uterine lining in order to support the implantation of an embryo.  The nutrients in sunflower seeds and sesame seeds assist with the production of progesterone and more.  Sunflower seeds are rich in the fat soluble vitamin E, which boosts the body’s natural progesterone production, and selenium, an essential mineral that supports the detoxification of excess estrogen within the liver. Sesame seeds contain plant lignins, which are a polyphenol, that work by supporting estrogen levels from increasing too high, and zinc, a mineral that supports the production of progesterone.

There are other health benefits to including sesame and sunflower seeds to your diet!  To learn about the Follicular Phase, and how flax and pumpkin seeds support your hormonal balance, check out my Follicular Phase Seed Cycling Cups: Days 1-14 HERE.

How to Start Seed Cycling

Seed Cycling is one of the easiest ways to add more nutrients to support a healthy hormonal balance.  During the follicular phase (days 1-14), you will eat 1 Tablespoon each of pumpkin and flaxseeds each day.  During the luteal phase (days 15-28), you will eat 1 Tablespoon of each sunflower and sesame seeds each day. 

Days 1-14: Follicular Phase, starts the first day of your period

  • Eat 1 Tablespoon of Pumpkin Seeds: ground
  • Eat 1 Tablespoon of Flaxseeds: ground

Days 15-28: Luteal Phase

  • Eat 1 Tablespoon of Sunflower seeds, ground
  • Eat 1 Tablespoon of Sesame seeds, ground

Seed Cycling FAQs

Q: When should I start seed cycling?

A: If you are menstruating, start on the first day of your next period.  If you are peri-menopausal or post-menopausal and are experiencing amenorrhea, start with the seed cycling anytime you like and follow the timeline of the 14-day rotation.

Q: What if my cycle is shorter? Longer?

A: Not everyone has a cycle that is 28-days, many of us are less than that and many of us are longer.  Everyone is different, and that’s okay.

If you cycle is shorter than 28 days like I was, then stop the luteal phase seeds and restart the follicular seeds when your period starts. Over time you may see improvement in the cycle length. If you have consistently shorter cycles, you may also decrease the number of days you are in each phase, for instance, if you have a 26-day cycle, you can choose to do each phase for 13 days instead of 14.  Listen to your body, you know what is best for you.

If you cycle is longer, I recommend sticking with the 14-day cycling as close as possible to help provide the necessary nutrients in supporting the body’s natural hormonal balance of a 28-day cycle. 

Q:  Do the seeds have to be ground?

A: Grinding the seeds helps to improve the availability of the nutrients in the seeds by breaking the seeds down into a more absorbable form.  You can grind them up in a coffee grinder, food processor, or blender and add them to different foods or make seed cycling cups to enjoy. 

Q: What if I can’t eat certain seeds?

A: Try to add the ones you can during the specific phases they support, and avoid flax and pumpkin seeds during your luteal phases and sesame and sunflower during your follicular phases.

Q: What if I don’t have time to ground fresh seeds everyday?

A: There are so many alternatives!  Make seed butter cups like I do and keep them in the fridge/freezer, make your own seed powder or seed butter to add to other foods, or even just buy organic seed butters (what I do A LOT) and eat a Tablespoon of each on some celery, apples, or toast!

Q: What are some other ways to add the seeds to my diet?

A: So many answers here, but I’ll throw these out!

Q: Can I keep these seed butter cups in the refrigerator so they aren’t as solid?

A: Absolutely! I just like to keep my frozen to keep the seed butter from running, this mixture is a bit softer than the follicular phase cups. If you are going to keep them in the fridge, I would opt for a container you could stack them up.

Q: Can I use whole sesame seeds in this recipe instead of the tahini?

A: Yes, you can! Just grind it first so you can maximize the absorption of the nutrients and stir it into the sunflower seed butter before making the seed butter cups.

Q: What if I have left over filling?

A: You can do a few things with it, I love to use any leftover seed butter filling to eat with apple slices, celery, on a sandwich, to add to smoothies or oatmeal, or just to eat by the spoonful! OR, you can make extra cups and save them for the next luteal cycle.
