What is Seed Cycling?

Spend time hanging round different well being areas, and also you’ll undoubtedly come throughout seed biking. This standard protocol goals “balance women’s hormones” and assist with all kinds of points associated to hormones and the menstrual cycle. Proponents use seed biking for every little thing from PMS signs, dysmenorrhea (painful menstruation), and irregular cycles to PCOS, infertility, ovarian cysts, and menopausal signs like sizzling flashes and evening sweats.

Testimonials abound from ladies who credit score seed biking with altering their lives. No scarcity of holistic docs, naturopaths, dietitians, and bloggers market it as a useful device, or perhaps a miracle treatment, for ladies. There are additionally loads of skeptics.

While it’s nice to maintain an open thoughts, we additionally need interventions that truly work. Nobody desires to throw invaluable money and time after cures that don’t do something or, worse, that trigger hurt. When you dig into the claims, they appear a bit too good to be true, however they aren’t. Let’s take a look at the proof.

Seed biking is a program the place you eat sure seeds throughout totally different phases of the menstrual cycle. According to proponents, if you happen to diligently comply with the protocol for a number of months, you’ll be able to count on to see enhancements in no matter signs or illness you’re hoping to deal with.

Seed biking seems like this:

During the follicular section (first day of menses to ovulation), devour one tablespoon of flax seeds and one tablespoon of pumpkin seeds per day.
During the luteal section (day after ovulation to day earlier than menses), devour one tablespoon of sunflower seeds and one tablespoon of sesame seeds per day.

Don’t know whenever you ovulate? No drawback, you are able to do flax and pumpkin for the primary half of your cycle (roughly days 1 to 14) and sunflower and sesame within the second half (days 15 to twenty-eight, or nevertheless lengthy your cycle is). Women who don’t menstruate are suggested to make use of the moon cycle as a information. New moon to full moon corresponds to the follicular section, full moon to new moon is luteal.

For digestibility, it’s vital to grind the flax seeds and sesame seeds. Usually, seed cyclers grind all of the seeds utilizing a spice mill or espresso grinder, or you should purchase premade seed blends. Sprinkle the bottom seeds over yogurt or salads, combine it into smoothies or soups, or simply make a sludgy shot of seed water.

How Does Seed Cycling (Supposedly) Work?

Seed biking advocates declare that it balances your hormones, which means that intercourse hormones (principally estrogen and progesterone) are at acceptable ranges at totally different factors of the menstrual cycle. When intercourse hormones plummet throughout menopause, seed biking allegedly helps mitigate these results, too. Supposedly, this works for plenty of causes.

First and foremost, seeds comprise compounds known as lignan precursors. When you eat them, micro organism within the intestine metabolize them to create lignans. Lignans are phytoestrogens, just like the isoflavones in soy. Because their chemical constructions are just like estrogens the physique produces naturally, lignans can bind to estrogen receptors and mimic the results of estrogen. Proponents say that lignans assist create a great stability of estrogen and progesterone within the physique, boosting estrogen when it’s too low and binding it to facilitate cleansing when it’s too excessive. (We’ll return to this declare later.)

Other alleged advantages come from nutritional vitamins and minerals within the seeds. Specifically:

Zinc, principally from pumpkin seeds and sesame seeds, is supposed to prime the physique to provide progesterone.
Vitamin E in sunflower seeds is likewise meant to encourage progesterone synthesis.
Selenium from sunflower seeds is meant to assist clear (or “detox”) the physique of extra estrogen.

But does it truly work like that?

That’s the million-dollar query.

As discerning well being customers, we have to perceive {that a} concept may be “mechanistically plausible,” which implies that whenever you clarify why it might work, it completely is sensible. However, it nonetheless may not be true. In science, hypotheses often begin with concepts which might be mechanistically believable, however then these hypotheses should be examined. Some hypotheses that appear utterly legitimate and wise don’t bear out underneath scrutiny. That’s why empirical analysis is significant.

Seed biking is mechanistically believable. Lignans are phytoestrogens, and flax and sesame seeds are each vital dietary sources of lignans. Zinc is vital for reproductive well being. Selenium does promote glutathione synthesis. Glutathione is a crucial antioxidant and an vital element of the physique’s pure cleansing system. The physique does excrete extra estrogen.

So you’ll be able to see the place the concept for this protocol might need come from. The drawback is, there actually isn’t any stable proof that seed biking truly does what it purports to do.

Yes, lignans are phytoestrogens, however scientists are nonetheless working to know how, precisely, lignans have an effect on intercourse hormone ranges. They may be both estrogenic or anti-estrogenic, however it’s not but clear how and once they exert totally different results. There’s undoubtedly no concrete proof that they work like good medicine, growing or reducing estrogen on an as-needed foundation to create optimum hormone stability.

Proponents of seed biking rely closely on one small research from 1993 that requested 18 ladies to devour flax seeds for 3 months. In this research, flax seed consumption led to fewer anovulatory menstrual cycles (cycles the place an egg just isn’t launched as anticipated) and a extra favorable progesterone-to-estradiol ratio throughout the luteal section. However, a lot of the results on intercourse hormone ranges weren’t vital. Tellingly, this research has by no means been replicated, which means the findings couldn’t be reproduced with extra highly effective research or different researchers didn’t suppose this was vital sufficient to comply with up on.

Overall, there may be solely the scantest proof that lignans instantly have an effect on intercourse hormone ranges. Plenty of research discover that they don’t. Moreover, do not forget that lignans are created within the intestine. Not everybody has the microbes wanted to transform excessive ranges of lignans. So even when seed biking does work as proponents declare, we’d count on that some individuals would profit far more than others.

Zinc, vitamin E, and selenium are undoubtedly vital for general well being and reproductive well being particularly. However, there’s nonetheless loads to find out about how supplementing impacts the outcomes we’re serious about right here. For instance, a 2020 overview entitled “The Role of Zinc in Selected Female Reproductive System Disorders” concluded that zinc dietary supplements could assist with PCOS and dysmenorrhea, however there’s a dearth of proof on the subject of points like endometriosis and menopause. Similarly, a 2016 overview of antioxidants concluded, “Given the complexities of hepatic processing and the contribution of diet and lipoprotein metabolism, additional research is needed to further explore the potential relations and mechanisms between particular vitamin E concentrations and reproductive outcomes.”

In brief, we nonetheless have a lot to find out about all these processes. Furthermore, the seed biking speculation depends on mechanistic pathways (A resulting in B) that aren’t at the moment well-supported by knowledge.

Seed Cycling Has Never Really Been Put to the (Empirical) Test

The backside line is that this protocol has by no means been rigorously examined. I couldn’t discover any research the place contributors adopted this actual routine and scientists in contrast their outcomes to a management group. Even if the proof for all of the mechanistic pathways was robust—and it isn’t—your complete protocol would nonetheless must be put to the take a look at.

Currently, all of the proof is anecdotal. To be clear, I’m not discounting the experiences from ladies who really feel like seed biking labored for them. Anecdotes may be informative, however we are able to’t rely solely on them. They depart too many questions unanswered.

For those that have success with seed biking, is it as a result of lignans, nutritional vitamins, minerals, and fatty acids are optimizing hormone stability? Maybe. Or perhaps it’s resulting from different compounds or totally different mechanisms like lowering irritation.
Could it’s a placebo impact? Perhaps (and also you may be comfortable with that so long as you get the outcomes you need).
Is there a greater manner to make use of seeds and/or the compounds they comprise to attain the identical targets? We don’t know.

These are all questions that well-designed, well-controlled laboratory research might reply. Studies that we don’t at the moment have.

The Verdict: Is Seed Cycling Worth Trying?

On the one hand, I’m tempted to say it will probably’t harm, may assist. Seeds supply plenty of different advantages. They are good sources of vitamins like B nutritional vitamins, magnesium, manganese, and copper, in addition to fiber and the aforementioned vitamin E, zinc, selenium, and fatty acids. Lignans have recognized antioxidant, anti-inflammatory, and anti-cancer properties. Flax and sesame seeds appear to have cardioprotective results. Pumpkin seeds can enhance blood glucose ranges.

On the opposite hand, many ladies flip to issues like seed biking after typical docs have been unable, and even unwilling, to assist them. PCOS and endometriosis victims notoriously wrestle to get correctly recognized and handled. We don’t have nice options for menopausal ladies coping with frequent signs like sizzling flashes, evening sweats, and melancholy. These ladies have been let down so many occasions. I’m due to this fact reluctant to offer a thumbs as much as one thing that has no stable proof behind it. There’s a danger, too, of delaying or avoiding medical therapy in favor of other therapies that in the end aren’t what you want.

Although the dangers of seed biking appear low, try to be conscious of some issues:

Seeds are excessive in phytates and may be allergenic, so that they don’t work for everybody.
They’re additionally excessive in fiber, resulting in gastrointestinal points for some of us.
Seeds aren’t allowed throughout the elimination section of the AIP plan.
If your physician has suggested you to restrict your consumption of phytoestrogens, ensure you discuss to them first.

Finally, if hormone well being is your purpose, step one is to ensure you’re nailing the big-ticket gadgets: vitamin, sleep, stress administration, and wholesome motion.

So what’s YOUR verdict? Are you curious about seed biking or not a lot? Have you tried it already?
