The Most Important Minerals for Fertility
When it comes to fertility, many people focus on hormones—and for good reason. Hormones like progesterone and estrogen play crucial roles in ovulation, menstrual cycle regularity, and preparing the body for pregnancy. However, what often gets overlooked is the foundational role that minerals play in the body’s ability to conceive and sustain a healthy pregnancy. Without a proper balance of essential minerals, hormone production can be impaired, leading to low progesterone, poor egg quality, and challenges with maintaining a healthy pregnancy.
Magnesium, potassium, sodium, copper, zinc, and iron are among the most important minerals for hormonal balance, ovarian function, and cellular energy. These minerals contribute to the production of steroid hormones like progesterone and help maintain the delicate balance of estrogen that’s necessary for conception. Low levels of these minerals can result in irregular cycles, anovulation (where ovulation doesn’t occur), and reduced egg quality, making it more difficult to conceive.
When preparing for pregnancy, nourishing yourself during pregnancy, and recovering in the postpartum period, ensuring optimal mineral balance is critical. Minerals are the foundation of our body’s physiological functions, and they play a vital role in fertility, healthy fetal development, and postpartum recovery. In this blog post, I’ll share my own HTMA results and how I am supporting myself postpartum, highlighting why focusing on specific minerals can make a significant difference in each phase.
The Role of Stomach Acid in Mineral Absorption
Another key aspect of fertility that often goes under the radar is the role of stomach acid in mineral absorption. Stomach acid (hydrochloric acid) is essential for breaking down food and releasing minerals so they can be absorbed effectively. Without sufficient stomach acid, the body may struggle to absorb crucial minerals like iron, zinc, and magnesium, even if you’re eating a nutrient-dense diet. This can lead to mineral deficiencies that impair fertility and overall reproductive health.
What’s even more fascinating is that the very minerals that we need for fertility—like zinc and sodium—are also crucial for the production of stomach acid. For instance, zinc plays a direct role in stimulating stomach acid production, while sodium is involved in the creation of chloride, a key component of hydrochloric acid. It’s a delicate cycle: without adequate minerals, stomach acid levels drop, which in turn further limits mineral absorption, creating a vicious cycle that can impact fertility.
Supporting both mineral levels and stomach acid production can create a healthier internal environment for hormone production and egg quality, making conception more likely and supporting a smooth transition into pregnancy.
The Specific Roles of Minerals in Preconception and Fertility
Minerals are the building blocks for a wide range of essential processes that support reproductive health and hormonal balance. Each mineral plays a unique role in preparing the body for conception, and deficiencies can create challenges in hormone production, egg quality, and overall fertility. Here’s a breakdown of the key minerals involved in preconception and fertility:
Magnesium: The Stress-Soothing Mineral
Magnesium is known as the “relaxation mineral” and is essential for regulating stress hormones like cortisol, which can interfere with progesterone production. Chronic stress can suppress ovulation, making it harder to conceive, but magnesium helps calm the nervous system and maintain balanced hormone levels. Additionally, magnesium is critical for blood sugar regulation, which is directly linked to hormone health. Insulin resistance and blood sugar fluctuations can lead to hormonal imbalances, making magnesium vital for those looking to conceive.
In preconception, magnesium also plays a role in muscle relaxation, including the uterine muscles, supporting a healthy uterine environment for implantation.
Potassium: Cellular Hydration and Energy
Potassium is essential for cellular hydration and electrolyte balance, which supports adrenal health and the body’s ability to produce adequate amounts of sex hormones. It also helps regulate blood pressure and works synergistically with sodium to maintain fluid balance, which is important for proper circulation and nutrient transport to the reproductive organs.
Potassium is particularly important for those experiencing fatigue or low energy, which can be a sign of underlying adrenal imbalances that affect fertility. Adequate potassium also helps support a healthy menstrual cycle, promoting overall reproductive health.
Sodium: Supporting Adrenals and Blood Volume
Sodium often gets a bad reputation, but it’s crucial for adrenal health and blood volume expansion, both of which are important in preparing the body for pregnancy. The adrenal glands play a significant role in producing sex hormones, particularly progesterone. Without enough sodium, the adrenals can become depleted, leading to low progesterone levels and difficulties with ovulation.
During pregnancy, blood volume increases by 50%, and sodium helps maintain the proper balance of fluids to support this expansion. It’s also vital for nerve function and ensuring electrical impulses between cells, which are crucial for hormonal signaling in the reproductive system.
Copper: Hormonal Balance and Egg Quality
Copper is essential for the formation of red blood cells, which helps deliver oxygen to tissues, including the reproductive organs. It also plays a role in the production of collagen, which helps maintain the structure and function of the ovaries.
Copper is intricately linked with estrogen metabolism, and an imbalance in copper levels can lead to issues like estrogen dominance, which can impact ovulation and egg quality. Balanced copper levels are necessary for the production of healthy eggs and overall hormonal harmony.
Zinc: The Fertility Mineral
Zinc is often called the “fertility mineral” due to its critical role in egg maturation, ovulation, and hormone production. It is involved in the synthesis of DNA and RNA, which are essential for cell division and growth—a process that’s key to the development of a healthy egg.
Zinc also helps regulate the balance between estrogen and progesterone, promoting regular menstrual cycles and a healthy luteal phase, which is crucial for implantation and sustaining early pregnancy. Zinc deficiency has been linked to anovulation (the absence of ovulation), so adequate levels are critical for anyone trying to conceive.
Iron: Oxygen and Blood Health
Iron is vital for the production of hemoglobin, the molecule in red blood cells that carries oxygen throughout the body, including to the ovaries and uterus. Proper oxygenation is necessary for egg development and the growth of the endometrial lining, which supports implantation.
Iron deficiency, or anemia, can lead to fatigue, poor egg quality, and inadequate blood supply to the reproductive organs, potentially contributing to difficulties in conceiving. Women with heavy menstrual bleeding are at an increased risk for iron deficiency, making it even more important to monitor and maintain optimal iron levels during preconception.
Other Relevant Minerals and Cofactors
- Iodine: This mineral is essential for thyroid health, and the thyroid plays a key role in regulating reproductive hormones. Low iodine levels can contribute to hypothyroidism, which can impair fertility and lead to irregular cycles.
- Selenium: A powerful antioxidant that protects eggs from oxidative stress and supports thyroid function. Selenium is also important for detoxification, helping the body remove harmful substances that can negatively impact fertility.
Stomach Acid and Mineral Absorption
One important aspect of fertility is ensuring that your body can absorb these essential minerals. Stomach acid is necessary for breaking down foods and releasing minerals like iron, zinc, and magnesium for absorption. If stomach acid is low, as it often is for people dealing with chronic stress or gut issues, mineral deficiencies can develop, even when eating a nutrient-dense diet. This is why supporting gut health and ensuring adequate stomach acid production is key to improving mineral absorption and overall fertility.
My own HTMA Insights during Pre-Conception
Magnesium, potassium, sodium, and copper are particularly essential during these stages. My own HTMA results before pregnancy revealed low levels of these minerals, and addressing them has been key to supporting my body through these changes. Here’s why these minerals matter:
- Magnesium: Crucial for relaxation, reducing stress, and supporting muscle function, magnesium also helps with sleep, which is vital during pregnancy and postpartum. It aids in balancing blood sugar levels, a common challenge during pregnancy.
- Potassium: Works alongside sodium to maintain fluid balance, support the adrenal glands, and ensure proper nerve and muscle function. Potassium is also essential for cellular hydration, which can impact energy levels and digestion. Potassium is also super helpful at preventing swelling in later stages of pregnancy.
- Sodium: Essential for maintaining proper blood volume and supporting adrenal function, especially as the body adapts to the increased demands of pregnancy. Adequate sodium helps prevent dizziness and fatigue, both of which are common during pregnancy.
- Copper: Plays a vital role in the development of red blood cells and is important for fetal growth and brain development. Copper is also necessary for maintaining a healthy balance of estrogen and progesterone, which are key hormones for fertility and pregnancy.
Here is how I supported each of these minerals during preconception:
During preconception, I focused on replenishing the minerals that my HTMA showed I was low in. For magnesium, I used Mag Soothe by Jigsaw at night and included magnesium-rich foods like dark leafy greens, pumpkin seeds, and almonds. For potassium, I drank a Pickleball cocktail 1-2 times per day and added cream of tartar to a mineral mocktail, plus I made sure to include a potassium-rich food (like bananas, avocados, or potatoes) with each meal. To boost sodium levels, I prioritized salting my food and often used Redmond Relyte for a daily mocktail. For copper, I took Oyster Zinc and upped my intake of copper-rich foods such as liver (I used the force of nature meats with liver mixed in), and dark chocolate. This balanced approach helped me support my body’s needs during this time.

Why Mineral Ratios Matter
Beyond looking at individual mineral levels, understanding the ratios between them can offer deeper insights into how the body is functioning. My pre-conception HTMA revealed the following ratios, which highlighted areas that needed support:
- High Ca/P ratio: Indicates stress and burnout and can point to low thyroid function. This is particularly important when trying to conceive, as thyroid health plays a role in hormone regulation and ovulation.
- High Ca/K ratio: Known as the “thyroid ratio,” this ratio can indicate a slowed thyroid, which can affect metabolic rate, energy levels, and the ability to maintain a healthy pregnancy.
- High Zn/Cu ratio: Indicates an imbalance between zinc and copper, which can impact immune function, hormone balance, and inflammation levels. A balanced Zn/Cu ratio is critical during pregnancy, as it helps support immune health and healthy fetal development.
- Low Na/Mg ratio: Reflects adrenal stress and difficulty maintaining electrolyte balance. This balance is key during pregnancy to support hydration and energy levels.
- High Ca/Mg ratio: Indicates a potential calcium dominance, which can affect muscle tension and blood sugar regulation. Balancing this ratio is important for muscle relaxation and preventing conditions like leg cramps during pregnancy.
