Trying to conceive can be a journey filled with excitement, hope and sometimes challenges. If you’re dealing with a thyroid condition, like Hashimoto’s, it’s so important to understand how your thyroid works with your body and how it can influence your fertility. But don’t worry—you’re not alone, and there’s a lot you can do to support your body during the preconception stage for better chances of conceiving. So, here’s what you need to know!
1. How the Thyroid Affects Hormones for Fertility
Your thyroid helps regulate key hormones like:
Progesterone & Estrogen: These two hormones are essential for preparing your body for pregnancy. Thyroid imbalances can disrupt their production and regulation, making it harder for your body to support a healthy pregnancy. Low levels of progesterone are very common with hypothyroidism but this hormone is responsible for supporting early pregnancy before the placenta takes over.

Cortisol: Known as the stress hormone, cortisol levels can be elevated in those with thyroid imbalances. Chronic stress can negatively impact ovulation and make it more difficult to conceive.
Insulin: Thyroid conditions can also affect your insulin sensitivity, which plays a role in your ability to conceive. Managing insulin resistance is key to balancing fertility hormones. If you think this might be an issue, get your healthcare provider to run a fasting glucose and insulin test to see how your body is responding. Focus on meals that include protein, healthy fats and fiber to keep your energy up and your blood sugar levels balanced.
2. Get a full thyroid panel blood test
When it comes to thyroid health, most doctors will only test for TSH but you can have underlying thyroid imbalances even if your TSH levels are in the “normal” range! The reason they generally only test for TSH is because the treatment is the same, a prescription for thyroid hormone. There sadly isn’t a lot of digging for root causes in conventional medicine. An autoimmune thyroid condition can have many causes – imbalances in the gut, infections, inflammation, environmental toxins, traumas, nutrient deficiencies, and other lifestyle factors. Taking thyroid medication alone won’t fix the problem that got you to that stage in the first place!
A full panel includes:
- TSH (Thyroid Stimulating Hormone)
- Free T3 and Free T4 (these are the active thyroid hormones)
- Reverse T3 (this can block T3, and you’ll want to know if it’s elevated)
- Thyroid Antibodies (to check if there’s any autoimmune stuff going on, like Hashimoto’s)
3. Nourish Your Thyroid with Key Nutrients
Supporting your thyroid through food is one of the best things you can do. There are a few key nutrients that are especially helpful for thyroid health:
- Zinc: This helps your body convert the thyroid hormone T4 into the active T3. If you’re on thyroid medication but are deficient in zinc, you will continue to struggle with these processes. You need zinc for your thyroid hormones but you also need thyroid hormones to absorb zinc! Foods like pumpkin seeds, chickpeas, oysters and cashews are packed with zinc.
- Selenium: Supports the conversion of T4 to T3 and helps reduce inflammation in the thyroid. Selenium is most abundant in the thyroid compared to all other organs in the body! Foods like Brazil nuts, eggs, and sunflower seeds are excellent sources of selenium. If supplementing, opt for the easily absorbed selenomethionine form.
- Iodine: You know that number in thyroid hormones, the 3 and 4? Those numbers are referring to the number of iodine molecules attached to the amino acid Tyrosine! While iodine deficiency can impair thyroid function, it’s important to strike a balance. Iodine-rich foods like seaweed, fish, and dairy are beneficial, but you shouldn’t overdo it—especially if you’re dealing with autoimmune thyroid disease like Hashimoto’s.
- Magnesium: This mineral supports thyroid function, balances blood sugar, and helps reduce stress, along with many other functions throughout the body. Leafy greens, almonds, dark chocolate and avocado are awesome sources of magnesium.
- B Vitamins: B12 and folate are essential, especially if you’re trying to conceive, but all of the B vitamins are important when it comes to the thyroid, with many of them being directly involved in synthesizing hormones! Eggs, dairy, meat, poultry and seafood, leafy greens, grains and legumes are great for these!
4. Support Your Gut for Better Digestion & Hormones
Did you know your gut health is closely tied to your thyroid health? An imbalance in the gut microbiome can affect how thyroid hormones are absorbed and metabolized, influencing fertility. Some ways to support gut health include:
- Lots of fiber from fruits, veggies, and whole grains to keep things moving and to feed your good bacteria.
- Probiotic-rich foods like yogurt, kimchi, and sauerkraut to help keep your gut bacteria happy.
- Less processed foods and sugar, which can mess with gut health and thyroid function.
5. Prioritize Sleep for Your Thyroid & Fertility
Sleep might be the easiest thing to overlook, but it’s crucial when it comes to thyroid health and fertility. Poor sleep messes with your cortisol levels, which in turn messes with your thyroid. Plus, you need that deep rest to support hormone production and balance.
Aim for 7-9 hours of sleep a night, and create a bedtime routine that helps you wind down. Maybe try some light stretching, reading, or listening to calming music before bed. And keep your bedroom dark, quiet, and cool for the best sleep.
6. Stress Management
Stress is a huge factor when it comes to thyroid health. When you’re stressed, your cortisol levels go up, which can make your thyroid function worse and mess with your fertility. It’s so important to find ways to manage that stress, even when life feels crazy.
Some things that help:
- Mindfulness or meditation, even just for a few minutes a day.
- Yoga or deep breathing exercises to calm your nervous system.
- Taking time to relax—whether that means a bath, a walk, or venting to a friend.
7. Move Your Body Every Day
Exercise is great for your thyroid and your fertility, but balance is key. Too much intense exercise can actually stress your thyroid out. Aim for gentle, regular movement like:
- Walking or light hiking
- Yoga or Pilates
- Strength training or resistance exercises a few times a week
Movement helps keep your blood circulating, supports healthy hormones, and boosts your overall well-being.
Trying to conceive with a thyroid condition can feel like a lot to juggle, but remember—you’re not alone in this. By focusing on nourishing your body with the right foods, supporting your thyroid with the proper care, and managing stress, you’re setting yourself up for success. Be patient with yourself, listen to your body, and don’t hesitate to reach out for support
