Seed Cycling for Balancing Hormones

Updated: Apr 19

Seed cycling has long been used to help support women’s hormones and menstrual cycles by providing their bodies with specific nutrients throughout the cycle.

What is seed cycling?

Seed cycling is a practice of eating certain seeds in a cycle that follows the menstrual cycle. These seed cycles occur in 2 week increments following the cyclical changes that happen with the menstrual cycle.

Follicular Phase - Ovulation (Days 1-14):

Eat 1-2 tbsp each of raw, fresh ground flax seeds and pumpkin seeds

Ovulation - Luteal Phase (Days 15-28):

Eat 1-2 tbsp each of raw, fresh ground sunflower and sesame seeds.

*These estimates are for women who have a regular 28 cycle and ovulated *approximately* on day 14. If your cycle is shorter or longer, adjust accordingly. If you don’t have a cycle to follow, it’s recommended to take these in a similar biphasic fashion throughout the month (2 weeks of one followed by 2 weeks of the other).

How Does Seed Cycling Work?

The beginning of your cycle is the first day you start your period. This marks the beginning of the follicular phase. On day 1, you will start consuming the follicular phase seeds and you’ll continue until day 14 or the day after you ovulate (if you are tracking ovulation). Flax seeds and pumpkin seeds help balance estrogen, which dominates this part of the cycle. You should consume 1tbsp of both flax and pumpkin seeds daily during the follicular phase.

After ovulation or day 15, you will switch to the luteal phase seeds. Sunflower and sesame seeds support progesterone levels, which dominates the second half of the cycle. You should consume 1 tbsp of both sunflower and sesame seeds daily until your period starts. Then re-start the cycle over again.

Seed cycling can be a great way to improve your nutrition throughout your cycle, but shouldn’t be used as a stand-alone therapy or used in place of a prescribed treatment. Incorporating seeds into your daily routine can not only support your reproductive health, but can provide you with a variety of nutrients, exposure to more essential fatty acids (EFAs), and can improve digestion.

What’s the science?

Unfortunately, there isn’t a lot of research directly focused on seed cycling currently. However, lack of direct evidence doesn’t disprove it’s medicinal capabilities. Women have been using seeds for decades to help make their cycles more comfortable. Even though there aren’t any studies on ‘seed cycling’ that exist, there are studies that examine these seeds and their individual benefits.

Follicular Blend:

Flax Seeds-

Are high in alpha-linolenic acid (ALA), a type of omega-3 fatty acid, lignans and fiber. Linoleic acid converts into GLA and DGLA which help to create prostaglandins which help stimulate ovulation to occur (prostaglandins can also be given to women to induce labor). Essential fatty acids (EFAs) also help to reduce inflammation, cramping, breast tenderness and fatigue.

There are phytoestrogens in flaxseed, which resemble the estrogen produced by our body. These help to increase estrogen levels which is the dominant hormone in the first half of our cycle. These can also help menopausal women who are dealing with hot flashes. Flaxseeds can also help to reduce high androgen levels like DHEA and testosterone which can balance estrogen.

Pumpkin Seeds-

Are high in Vitamin E, unsaturated fatty acids, and proteins. These components can help reduce oxidative stress- which can cause inflammation. High levels of inflammation can lead to cramping, migraines, and breast tenderness during the PMS window. Zinc is important for testosterone health and production. Pumpkin seeds are also high in antioxidants, which are essential for reproductive function and support of ovaries, uterus, and other organ systems.

Interestingly, they have been shown to have anti-depressive effects. They contain an amino acid called tryptophan. This is a pre-cursor to serotonin which is the neurotransmitter that makes us feel happy and at -ease. Serotonin is also a precursor to melatonin. This may be why women who have used them for months report better sleep.

Luteal Blend:

Sunflower Seeds-

High in unsaturated fats and Vitamin E. Vitamin E is made up of tocopherols and tocotrienols- from Greek tokos means ‘birth’ and pherein means ‘to bear or carry’. Its components were named after its connection to fertility!

Sunflower seeds help to lower blood glucose levels which can support healthier progesterone levels during the luteal phase and can help to reduce sweet cravings. These can also have a positive effect on your cholesterol. Cholesterol is the building block for all of your sex hormones.

Sesame Seeds-

Have high levels of lignans that can help with estrogen detoxification. One of the more common causes of PMS is high levels of estrogen in the luteal phase. Sesame seeds are also high in B vitamins which help with neurotransmitter production like GABA and dopamine. Increasing these levels during the luteal phase may help reduce brain fog, difficulty concentrating and improve focus.

This added source of fiber can also help to promote healthy digestion and more regular bowel movements. Getting adequate amounts of fiber can also help to better regulate blood glucose levels and improve insulin resistance.

Where can I buy them?

You can find full seeds and ground seeds at natural health food stores. Always opt for an organic brand! If you’re consuming non-ground seeds, you may need to increase your intake.

I have personally used seeds from Funk it Wellness This female-owned company sources all organic and non-GMO seeds for their blends. They are easy to mix with water or in smoothies and honestly taste real good. Use ZAREMBA15 to save 15% on your order!

Seed cycling alone should not be used to regulate hormones or address any reproductive disorders, but it can be helpful in providing a variety of nutrients, antioxidants, fatty acids, and proteins to your diet. There are many benefits of consuming these seeds outside of the hormonal factors and can help improve health as a whole.
