Spend time hanging round different well being areas, and also you’ll undoubtedly come throughout seed biking. This in style protocol goals “steadiness girls’s hormones” and assist with all types of points associated to intercourse 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 night time sweats.

Testimonials abound from girls who credit score seed biking with altering their lives. No scarcity of holistic medical doctors, naturopaths, dietitians, and bloggers advertise as a useful instrument, or perhaps a miracle remedy, for ladies. There are additionally loads of skeptics.

Whereas it’s nice to maintain an open thoughts, we additionally need interventions that really work. No one desires to throw useful money and time after treatments that don’t do something or, worse, that trigger hurt. While 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.

What’s Seed Biking?

Seed biking is a program the place you eat sure seeds throughout completely different phases of the menstrual cycle. In response to proponents, for those who diligently observe the protocol for a number of months, you may anticipate to see enhancements in no matter signs or illness you’re hoping to handle.

Seed biking appears like this:

  • Through the follicular section (first day of menses to ovulation), eat one tablespoon of flax seeds and one tablespoon of pumpkin seeds per day.
  • Through the luteal section (day after ovulation to day earlier than menses), eat 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). Girls 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 necessary to grind the flax seeds and sesame seeds. Often, 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 Biking (Supposedly) Work?

Seed biking advocates declare that it balances your hormones, which means that intercourse hormones (largely estrogen and progesterone) are at appropriate levels at completely different factors of the menstrual cycle. When intercourse hormones plummet throughout menopause, seed biking allegedly helps mitigate these results, too. Supposedly, this works for a lot of causes.

At the start, seeds comprise compounds referred to as lignan precursors. While you eat them, micro organism within the intestine metabolize them to create lignans. Lignans are phytoestrogens, just like the isoflavones in soy. As a result of 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 an excellent steadiness 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.)

Different alleged advantages come from nutritional vitamins and minerals within the seeds. Particularly:

  • Zinc, largely 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.

However does it truly work like that?

That’s the million-dollar query.

As discerning well being shoppers, we have to perceive {that a} principle might be “mechanistically believable,” which signifies that whenever you clarify why it might work, it completely is sensible. Nonetheless, it nonetheless may not be true. In science, hypotheses normally 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 below scrutiny. That’s why empirical analysis is important.

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

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

Sure, lignans are phytoestrogens, however scientists are nonetheless working to know how, precisely, lignans have an effect on intercourse hormone ranges. They are often both estrogenic or anti-estrogenic, nevertheless it’s not but clear how and after they exert completely different results. There’s positively no concrete proof that they work like good medication, growing or reducing estrogen on an as-needed foundation to create optimum hormone steadiness.

Proponents of seed biking rely closely on one small examine from 1993 that requested 18 girls to eat flax seeds for 3 months. On this examine, flax seed consumption led to fewer anovulatory menstrual cycles (cycles the place an egg isn’t launched as anticipated) and a extra favorable progesterone-to-estradiol ratio through the luteal section. Nonetheless, a lot of the results on intercourse hormone ranges weren’t vital. Maybe tellingly, this examine has by no means been replicated, suggesting the findings couldn’t be reproduced with extra highly effective research or different researchers didn’t assume this was value following up on.

General, there may be solely scant proof that lignans immediately have an effect on intercourse hormone ranges. Loads of research discover that they don’t. Furthermore, 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 anticipate that some folks would profit rather more than others.

Zinc, vitamin E, and selenium are undoubtedly necessary for total well being and reproductive well being particularly. Nonetheless, there’s nonetheless  so much to study how supplementing impacts the outcomes we’re concerned with right here. For instance, a 2020 evaluation entitled “The Function of Zinc in Chosen Feminine Reproductive System Problems” concluded that zinc dietary supplements might assist with PCOS and dysmenorrhea, however there’s a dearth of proof relating to points like endometriosis and menopause. Equally, a 2016 evaluation of antioxidants concluded, “Given the complexities of hepatic processing and the contribution of food plan and lipoprotein metabolism, extra analysis is required to additional discover the potential relations and mechanisms between specific vitamin E concentrations and reproductive outcomes.”

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

Seed Biking Has By no means Actually Been Put to the (Empirical) Take a look at

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

At the moment, all of the proof is anecdotal. To be clear, I’m not discounting the studies from girls who really feel like seed biking labored for them. Anecdotes might be informative, however we are able to’t rely solely on them. They go away too many questions unanswered.

  • For individuals who have success with seed biking, is it as a result of lignans, nutritional vitamins, minerals, and fatty acids are optimizing hormone steadiness? Perhaps. Or possibly it’s as a result of different compounds or completely different mechanisms like lowering irritation.
  • May it’s a placebo impact? Maybe (and also you is likely to be pleased 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 realize the identical objectives? We don’t know.

These are all questions that well-designed, well-controlled laboratory research might reply. Research that we don’t presently have.

The Verdict: Is Seed Biking Value Attempting?

On the one hand, I’m tempted to say it might probably’t harm, would possibly assist. Seeds offer lots of other benefits. They’re 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 identified antioxidant, anti-inflammatory, and anti-cancer properties. Flax and sesame seeds appear to have cardioprotective results. Pumpkin seeds can enhance blood glucose ranges.

Then again, many ladies flip to issues like seed biking after standard medical doctors have been unable, and even unwilling, to assist them. PCOS and endometriosis victims notoriously battle to get correctly identified and handled. We don’t have nice options for menopausal women dealing with common symptoms like sizzling flashes, night time sweats, and melancholy. These girls have been let down so many occasions. I’m subsequently reluctant to present an enthusiastic thumbs as much as one thing that has no strong proof behind it. There’s a danger, too, of delaying or avoiding medical remedy in favor of other therapies that in the end aren’t what you want.

Though the dangers of seed biking appear low, you ought to be conscious of some issues:

  • Seeds are excessive in phytates and might 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 through the elimination section of the AIP plan.
  • In case your physician has suggested you to restrict your consumption of phytoestrogens, be sure you speak to them first.

Lastly, if hormone well being is your objective, step one is to be sure you’re nailing the big-ticket objects: diet, sleep, stress administration, and wholesome motion.

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