If you had asked me to talk about how quitting veganism helped me heal my hormones and get pregnant even a year ago, I probably wouldn’t have been comfortable doing so.  

Why?

Because for the longest time, I never wanted to ruffle any feathers. I didn’t want to upset anyone. In short, I was a chronic people pleaser who hated confrontation. And if you know anything about the vegan community—especially online—they can be ruthless.

But motherhood has taught me many things and truly forced me to face some of my deepest insecurities. Along the way, I’ve gained the confidence to talk about topics that not everyone might agree with.  

So, let’s dig in...

A Quick Backstory

My husband and I were vegan for four years. That meant we ate NOTHING that came from an animal—no meat, cheese, yogurt, milk, honey, fish, eggs, etc. We even fed our dogs vegan dog food. I didn’t buy anything made of leather, and I even started a vegan food blog. I was PASSIONATE about this lifestyle and thought I’d eventually open a private practice as a vegan dietitian.  

Then, during my last year of grad school, I started experiencing major hormone-related symptoms:

• Heavy and painful periods

• Adult acne

• Severe fatigue

• Hair loss

• Difficulty concentrating

  
  

I finally decided to work with a functional dietitian and completed an HTMA (Hair Tissue Mineral Analysis). That test opened my eyes to a whole new world. Based on my lab work, the dietitian suggested incorporating some animal products into my diet.  

I wouldn’t have even considered it had I not felt like I was losing myself because of my symptoms. I was desperate for relief and willing to try something different. Deep down, my intuition had been nudging me toward this change, but I had resisted for over a year at this point.  

Fast forward to a year later: I had officially added animal products back into my diet, worked to heal and balance my hormones, and was feeling SO much better. I truly view that year as my “pregnancy prep” phase and KNOW it contributed to conceiving quickly and having a healthy pregnancy.  

Why a Vegan Diet Isn’t the Most Supportive for Preconception, Fertility, and Pregnancy

While vegan diets can work for some, they do lack critical nutrients necessary for fertility, conception, and pregnancy. 

Here’s why:

Low in Bioavailable Protein

• Animal proteins provide all essential amino acids in forms that are easily absorbed and utilized by the body. Plant proteins often lack one or more essential amino acids, making it harder to meet the higher protein needs during preconception and pregnancy.

Absorption Differences

• The body absorbs 90–100% of the protein from animal sources.

• Plant proteins are absorbed at a lower rate, around 70–90%, due to fiber, anti-nutrients like phytates, and incomplete amino acid profiles.

Low in Choline

• Choline is crucial for fetal brain development and preventing neural tube defects. The richest sources are eggs (especially the yolks) and liver, both of which are absent from vegan diets.

Low in Retinol (Active Vitamin A)

• Vitamin A is essential for reproductive health and fetal development. While beta-carotene from plants can convert to vitamin A, the conversion rate is inefficient and varies from person to person. Retinol, the active form of vitamin A, is found in animal products like liver, eggs, and dairy.

Deficient in Vitamin B12

• B12 is critical for red blood cell formation, neurological function, and DNA synthesis. Since it’s found exclusively in animal products, vegans must rely on supplementation, which might not always provide sufficient levels.

Low in DHA and EPA (Omega-3 Fatty Acids)

• These long-chain omega-3s are vital for brain and eye development in a growing baby. While plant sources provide ALA (a precursor to DHA/EPA), the body’s conversion is highly inefficient. Fatty fish, fish oil, or algae-based DHA are far superior sources.

Lower Bioavailability of Key Minerals

• Iron, zinc, and calcium are harder to absorb from plant sources due to the presence of anti-nutrients like phytates. Animal products offer these minerals in more bioavailable forms.

High in Anti-Nutrients

• Many plant-based foods contain compounds (like oxalates and lectins) that can interfere with nutrient absorption, potentially leading to deficiencies over time.

Potential for Hormonal Imbalances

• Vegan diets are often high in carbohydrates and soy-based foods, which can disrupt hormonal balance for some individuals, particularly those with estrogen-dominant conditions.

I’m certainly not trying to hate on a vegan diet, but rather speaking from my personal experience and from working with so many women who, at one point in their lives, were vegan or vegetarian. For me, transitioning away from veganism was the key to healing my hormones, optimizing my health, and preparing my body for pregnancy.
