Fertility is a deeply personal and sometimes complex journey. Whether you are actively trying to conceive, planning for the future, or simply curious about your health, understanding the many factors that influence fertility can be empowering. In honour of Fertility Month, we are highlighting five often-overlooked nutrition and lifestyle factors that can play a role in reproductive health for all genders.

1. Vitamin D: More Than the “Sunshine Vitamin”

Most people know vitamin D for its role in bone health, but it is also important for fertility. Research shows that vitamin D supports ovarian function, hormone balance, egg quality, and even helps prepare the uterus for implantation. For those undergoing fertility treatments such as IVF, vitamin D may also support better outcomes.

In Canada, it is challenging to get enough vitamin D from food and sunlight alone, especially during the winter months. While foods like fatty fish, egg yolks, and fortified products can help, a daily supplement of at least 1,000 IU is often recommended. If you are concerned about your vitamin D status, consider speaking with your healthcare provider about testing.

2. Iron: Essential for Reproductive Health

Iron is commonly associated with energy and preventing anemia, but it is also crucial for ovulation and a healthy uterine lining. Low iron can affect blood flow to the ovaries and disrupt regular cycles, making conception more difficult. While iron deficiency is more common in women, everyone can benefit from ensuring adequate intake.

Iron comes in two forms: heme (from animal sources such as red meat and poultry) and non-heme (from plant sources such as lentils and spinach). Pairing plant-based iron with vitamin C-rich foods, like bell peppers or strawberries, can boost absorption. If you are experiencing fatigue, heavy periods, or notice pale nail beds, it may be worth discussing iron testing with your doctor.

3. Environmental Toxins: Awareness, Not Perfection

Environmental toxins are present in many aspects of daily life, including personal care products, cleaning supplies, plastics, and pesticides. Many of these chemicals are known as endocrine disruptors, which means they can mimic or block natural hormones and potentially impact fertility over time.

While it is impossible to avoid all exposures, small changes can make a difference. Consider using glass or stainless steel containers instead of plastic, washing fruits and vegetables thoroughly, and choosing natural cleaning or personal care products when possible. The goal is not perfection, but rather increased awareness and gradual improvement.

4. Sleep: The Unsung Hero of Fertility

Quality sleep is often underestimated when it comes to reproductive health. Poor sleep can disrupt hormones such as cortisol and melatonin, both of which play roles in ovulation, egg quality, and overall hormonal balance. Chronic sleep deprivation can also increase inflammation and affect blood sugar regulation, further impacting fertility.

Simple strategies to improve sleep include maintaining a consistent sleep schedule, limiting caffeine and alcohol (especially in the evening), reducing screen time before bed, and practicing stress-reducing activities. Even small improvements in sleep quality can have a positive effect on your overall health.

5. Gut Health: More Than Digestion

Gut health is a popular topic for good reason. Beyond digestion, your gut plays a key role in hormone regulation, especially estrogen. A healthy gut microbiome helps process and eliminate excess estrogen, supporting hormonal balance and fertility. Signs of gut imbalance can include bloating, constipation, diarrhea, new food sensitivities, or even skin changes such as acne or eczema.

Supporting gut health does not require expensive supplements or drastic changes. Focus on regular meals, adequate fibre, hydration, and a variety of plant-based foods to nourish your gut microbiome. Small, sustainable habits can make a meaningful difference over time.
