When we talk about “glowing up” your fertility, we’re really talking about optimizing the environment your body needs to support hormone balance, ovulation, and overall reproductive health ✨

One of the most impactful, and often overlooked, pieces is your Omega-3 intake.

Omega-3 fatty acids play a key role in reducing inflammation, supporting egg quality, and improving hormone signaling. They also contribute to healthy cervical mucus and support implantation by promoting a more receptive uterine environment.

Many women are unintentionally deficient, especially if their diet is low in fatty fish or high in processed oils rich in Omega-6s.

Increasing your Omega-3 intake can look like:
• Incorporating fatty fish like salmon, sardines, and mackerel 2–3x per week
• Adding in chia seeds, flaxseeds, and walnuts
• Considering a high-quality fish oil supplement when appropriate

This is not about perfection, but about creating consistent inputs that support your body at a foundational level.

Small shifts, done consistently, can have a meaningful impact over time.

Save this as part of your fertility support toolkit, and follow along for Part 5 🤍

A little peek into the other side of life ✨

Beyond the clinic, I am also a mama. And that part of my life is what shaped so much of the work I do today.

Walking through my own journey gave me a deeper understanding of how complex, emotional, and personal fertility can be. It is more than protocols and labs, it is real life in motion between appointments.

Sharing a bit of the moments you don’t always see on here, but that mean everything.

Thank you for being here for all of it.

Why does thyroid dysfunction get missed so often?

Because symptoms are easy to dismiss.
Fatigue, weight changes, irregular cycles, hair loss, brain fog, mood shifts — they get labeled as stress, postpartum, or “just hormones.”

And then the labs come back “normal.”

But here’s where nuance matters.

Thyroid physiology is more complex than a single TSH value.
And at the same time, not every advanced marker you see online is actually helpful.

One of the most over-discussed markers in the wellness space is reverse T3.

Reverse T3 is often marketed as a key driver of symptoms or a sign that your body is “shutting down metabolism.” In reality, for most patients, it is a byproduct of normal thyroid hormone metabolism and can fluctuate with stress, illness, or calorie restriction.

It is not a primary driver of thyroid disease.
And it is rarely the missing piece.

Over-focusing on reverse T3 can lead to unnecessary supplements, over-treatment, and a lot of confusion, without actually improving outcomes.

What matters more?

A comprehensive, evidence-based evaluation that looks at TSH, free T4, free T3 when indicated, thyroid antibodies, and how this all connects to your symptoms, your cycle, and your metabolic health.

Because thyroid function does not exist in isolation.
It is deeply connected to fertility, ovulation, and overall hormone balance.

If you feel like something is off, even when you have been told everything is “normal,” it is worth looking deeper.

Just make sure you are looking in the right places.

If you’re trying to support your fertility, supplements can be a helpful piece of the puzzle when used intentionally ✨

I say this with so much care, because I see it every day.
Women spending hundreds of dollars on supplements, taking handfuls of things they saw online, and still not getting results.

Not because they are not trying hard enough.
But because no one has shown them what their body actually needs.

More is not better.
And the wrong supplements, in the wrong doses, can create imbalances, interfere with absorption, and in some cases, work against your fertility goals.

There is a place for foundational support like a high-quality prenatal and omega-3s.
And there is a place for more targeted nutrients like CoQ10 or inositol when clinically indicated.

But this should be guided by your labs, your cycle, and your specific physiology.

Fertility is not about guessing your way through a supplement routine.

It is about working with the right provider who can interpret your labs, connect the dots, and create a plan that is precise, not excessive.

You should not have to waste time or money trying to figure this out on your own.

If you are ready for a more strategic, evidence-based approach to your fertility, follow along for more education on hormone health, labs, and what actually moves the needle.

Save this for later when you’re choosing your supplements, or send it to someone who’s on this journey too 🤍

We’re back with our series: 26 Ways to Glow Up Your Fertility in 2026 ✨

Let’s talk about cycle tracking and the rise of wearables like Oura rings and fertility bracelets.

These tools can be a much easier, more consistent alternative to traditional basal body temperature tracking. Instead of remembering to take your temperature first thing every morning, they passively track overnight trends like body temperature, sleep, and recovery.

And yes, that data can be helpful.

Over time, you may start to see patterns in your cycle, confirm ovulation, and better understand how your body is responding month to month.

But this is where I want you to zoom out.

These devices are a piece of the picture, not the full picture.

They can help confirm that ovulation happened.
They cannot tell you if ovulation was optimal.
They do not assess progesterone levels, egg quality, thyroid function, or metabolic health.

And they should not replace proper lab work or a comprehensive fertility evaluation.

So if you love your Aura ring or bracelet, keep using it. It can absolutely support awareness and consistency.

Just make sure you are not relying on it as your only source of truth.

Fertility is not about one data point. It is about how everything connects.

Follow along for more evidence-based ways to actually support your fertility in 2026.

PCOS management isn’t just about symptom control. It’s about supporting the systems in the body that influence hormones in the first place.

Here are a few foundational areas I often focus on when approaching PCOS from a natural, root-cause perspective:

• Balance blood sugar
Blood sugar and insulin signaling play a major role in PCOS. Building meals around protein, fiber, and healthy fats can help stabilize energy, reduce cravings, and support more balanced hormone communication.

• Support insulin sensitivity
Movement, muscle building, sleep quality, and key nutrients can all help the body respond to insulin more effectively, which is one of the biggest drivers behind many PCOS symptoms.

• Reduce inflammation
Chronic inflammation can worsen hormonal imbalance. Prioritizing whole foods, omega-3 fats, gut health, and reducing ultra-processed foods can make a meaningful difference over time.

• Support ovulation and androgen balance
When the body begins ovulating more consistently, many symptoms start to improve. Targeted nutrition, lifestyle shifts, and supportive therapies can help regulate cycles and lower excess androgens.

• Address root causes
PCOS doesn’t show up the same way for everyone. Gut health, stress hormones, thyroid function, and nutrient deficiencies can all influence how it manifests.

Managing PCOS naturally isn’t about quick fixes. It’s about supporting the body in a more sustainable way.

If you’re navigating PCOS, I’d love to hear from you. Comment “”PCOS”” or share your experience below so we can open the conversation 🤍

• Test your gut. This is one of the most overlooked pieces of fertility. Gut health influences inflammation, nutrient absorption, estrogen metabolism, and even ovulation signaling. If the gut is struggling, hormones often follow.

• Look deeper than “normal” labs. Optimal hormone levels and functional patterns matter far more than simply falling inside a wide reference range.

• Support blood sugar balance. Stable glucose and insulin signals play a major role in ovulation, egg quality, and hormone communication.

• Don’t ignore mineral status. Nutrients like magnesium, zinc, iron, and selenium are foundational for hormone production and thyroid health.

• Address chronic stress on the body. This includes sleep deprivation, overtraining, under-eating, and emotional stress. The nervous system plays a huge role in reproductive signaling.

• Prioritize egg quality early. Egg development actually begins months before ovulation, so what you do now matters for the cycles ahead.

• Remember fertility is a whole-body conversation. Gut health, thyroid function, inflammation, nutrient status, and nervous system regulation are all part of the picture.

Fertility isn’t just about trying harder. Often it’s about looking deeper.

Comment “fertility” if you want to learn more about testing and the root causes we often look at when supporting women on their conception journey, and let’s open the discussion. 🤍

Postpartum recovery is often spoken about in weeks, but hormonally, the story is much longer and much more nuanced.

After birth, estrogen and progesterone drop dramatically within the first 24 hours. It’s one of the most significant hormonal shifts the human body will ever experience. At the same time, other hormones like prolactin, cortisol, and oxytocin begin adjusting to support healing, milk production, and the emotional bond between mother and baby.

This transition can feel beautiful, overwhelming, exhausting, and sacred all at once.

In naturopathic endocrinology, we view postpartum recovery as a gradual recalibration rather than a quick “bounce back.” While the initial physical healing may happen in the first 6–8 weeks, the endocrine system can take anywhere from several months to a full year to find its new rhythm.

That timeline is not a sign that something is wrong. It’s a reflection of how intelligent and complex the body truly is.

During this time, the body is asking for nourishment, rest, and gentle support. Minerals become incredibly important. Blood sugar stability matters more than many realize. Thyroid function can shift. Adrenal hormones adjust to new sleep patterns and stress levels. Every system is learning how to work again in a new season of life.

This is why postpartum care should never end at the six week visit.

True recovery honors the full hormonal timeline. It honors the mother as much as the baby. And it recognizes that healing after birth is not something to rush, but something to support with patience, compassion, and the right tools along the way.

If you’re in this season, know that your body is not broken or behind. It is recalibrating in the most profound way.

We’re back with Part 2 ✨

26 Ways to Glow Up Your Fertility in 2026 continues today with something simple, but powerful: gentle movement.

Fertility thrives in a body that feels safe and supported. Consistent, low impact movement like walking, strength training, Pilates, or yoga can improve insulin sensitivity, support ovulation, reduce inflammation, and regulate stress hormones.

This is not about overtraining. It is about intentional movement that works with your hormones, not against them.

Follow along as we continue this series and share evidence-based ways to truly support your fertility this year 🤍

PCOS is one of the most misunderstood hormone conditions I see.

There is so much noise around what it is, what causes it, and what you “have” to do to manage it. The truth is, PCOS is nuanced. It is not one size fits all, and it is not a life sentence.

Understanding the difference between myths and facts is the first step toward supporting your body with clarity and confidence.

Follow along for evidence-based guidance and real peace of mind when it comes to your hormones and PCOS 🤍

Even if your TSH levels are “normal,” you may still notice symptoms or challenges with conception.

TSH, or thyroid stimulating hormone, plays an important role in ovulation, progesterone support, and preparing your body for implantation. Sometimes, “normal” lab ranges aren’t quite optimal for fertility, and small differences can make a meaningful impact.

If you’re trying to conceive and still feeling off, it may be worth looking closer at your thyroid to ensure it’s truly supporting you 🤍

If you’re on your fertility journey, trying to conceive, and haven’t had your thyroid fully evaluated, this is your reminder.

Thyroid hormones regulate ovulation, support progesterone, and are essential for implantation and early pregnancy. Even mild dysfunction, including subclinical hypothyroidism or autoimmune conditions like Hashimoto’s, can influence fertility outcomes.

Certain fertility medications can increase your thyroid hormone demand. Without proper monitoring, this can impact cycle response and early pregnancy support.

During controlled ovarian stimulation (IVF/IUI), estradiol rises to late-pregnancy levels, affecting your thyroid:

TSH increases significantly
44% of women with normal baseline TSH rose above 2.5 mIU/L
Women on thyroid medication have more pronounced TSH increases
Women with thyroid antibodies (TPOAb+) show even higher TSH

Why it matters:
🔹 Lower clinical pregnancy rates
🔹 Lower live birth rates
🔹 Higher miscarriage risk

Who is most at risk?
Women with hypothyroidism
Women with thyroid autoimmunity (Hashimoto’s/TPOAb+)
Women with baseline TSH in the upper-normal range

Thyroid care is essential in IUI/IVF—fertility care should never focus on one hormone alone.

Before treatment:
Get a thyroid evaluation (TSH, free T4, TPO antibodies)
Discuss dose adjustments if on thyroid medication
Monitor thyroid during and after stimulation

If this is your season, make sure it’s fully supported.
