Understanding Your Diet: Does FAGE Greek Yogurt Have Hormones?

October 19, 2025 •

4 min read

According to FAGE's official US website, all of their yogurts are made with milk from cows that have not been treated with growth hormones. This assurance directly addresses a primary consumer concern and is supported by their Non-GMO Project Verification. However, understanding the full picture of whether Does FAGE Greek yogurt have hormones? requires distinguishing between synthetic hormones, like rBST, and the hormones that naturally occur in all dairy products.

Quick Summary

This article clarifies FAGE's company policy regarding synthetic growth hormones in their US yogurt products. It explores the difference between naturally occurring hormones in dairy and artificial ones like rBST. The content also covers how to interpret food labels and weigh potential consumer concerns about hormones within a healthy nutrition diet.

Key Points

FAGE is rBST-Free: FAGE confirms its US products use milk from cows not treated with synthetic growth hormones like rBST (rBGH).
Natural Hormones are Present: All dairy products, including FAGE yogurt, naturally contain hormones like estrogen and IGF-1, which are different from added synthetic hormones.
Labeling is Crucial: The 'rBST-free' label indicates no added synthetic hormones, while 'organic' yogurt provides broader assurances about animal welfare and non-synthetic farming practices.
Consider Health and Ethics: Consumer concerns regarding rBST involve potential health impacts (especially increased IGF-1) and animal welfare, influencing the preference for hormone-free and organic dairy.
FAGE offers Nutritional Benefits: Beyond hormone status, Greek yogurt is a nutritious food rich in protein and probiotics, beneficial for gut health and weight management.
Informed Choice: Understanding the differences between synthetic and natural hormones in dairy empowers consumers to make choices aligned with their dietary and ethical preferences.

FAGE's Stance on Synthetic Growth Hormones

For consumers concerned about added hormones in their food, FAGE provides clear messaging. The company states that all of its yogurt products in the U.S. are made from milk sourced from cows that have not been treated with recombinant bovine somatotropin (rBST), also known as recombinant bovine growth hormone (rBGH). Their Non-GMO Project Verified status further confirms this commitment to natural ingredients. This assurance is a key selling point for FAGE and other dairy producers who choose to avoid the use of artificial growth stimulants.

What is rBST and Why Does It Cause Concern?

rBST is a synthetic hormone developed to mimic a cow's natural growth hormone, bovine somatotropin (BST). It is injected into dairy cows to increase their milk production. While the U.S. Food and Drug Administration (FDA) has stated that milk from rBST-treated cows is safe for human consumption, some health and ethical concerns have persisted. These include:

Potential for Increased IGF-1 Levels: Some studies suggest milk from rBST-treated cows may contain higher levels of Insulin-like Growth Factor-1 (IGF-1), a hormone naturally present in milk. High levels of IGF-1 have been linked in some research to an increased risk of certain cancers, though the evidence is not conclusive.
Animal Welfare: The use of rBST can increase milk yield, which places additional stress on cows. This can lead to a higher risk of health issues like mastitis, an infection of the mammary glands.
Consumer Preference: A growing number of consumers prefer to purchase products from farms that do not use artificial hormones, driving many companies, including FAGE, to adopt rBST-free policies.

The Reality of Naturally Occurring Dairy Hormones

Even in yogurt labeled rBST-free, it is crucial to understand that all milk naturally contains hormones. The milk of mammals, including cows and humans, is a complex biological fluid that contains a variety of hormones and growth factors, such as prolactin, steroids (like estrogen), and IGF-1. These natural hormones play a role in the cow's biology and are a normal component of milk.

The key distinction lies in the concentration and type of hormones present. While FAGE's milk is free from added synthetic growth hormones, it still contains the hormones produced by the cows naturally. The concentration of these natural hormones can fluctuate based on factors like the cow's breed, age, and pregnancy stage. Concerns exist, for instance, that milk from pregnant cows may have higher levels of natural estrogens. However, some studies suggest that the oral bioavailability of these hormones upon human consumption is low.

How to Navigate Dairy Hormone Concerns

For a balanced nutrition diet, understanding the different types of hormones and what labels mean is key. Here is a guide:

Look for 'rBST-Free' or 'No rBGH' Labels: This indicates the product comes from cows not treated with synthetic growth hormones, which FAGE confirms for its US products.
Consider Organic Dairy: Organic certification prohibits the use of synthetic rBST and mandates stricter guidelines for animal feed and care. For consumers with broader concerns beyond rBST, organic dairy is often a preferred choice.
Focus on Nutrient Profile: Regardless of the hormone debate, Greek yogurt like FAGE offers significant nutritional benefits, including high protein content and probiotics. Choosing plain, unsweetened versions helps avoid unnecessary added sugars.
Maintain a Balanced Diet: Incorporating dairy products in moderation alongside a wide variety of fruits, vegetables, and other whole foods is fundamental to a healthy diet.

Frequently Asked Questions

rBST (recombinant bovine somatotropin) is a synthetic hormone used to increase milk production in dairy cows. Concerns include potential health risks from increased IGF-1 levels in the milk and ethical issues regarding animal welfare due to increased stress on the cows.

No, like all dairy products, FAGE Greek yogurt contains naturally occurring hormones. However, it is free of added synthetic growth hormones like rBST.

Not necessarily. 'rBST-free' only guarantees that synthetic growth hormones were not used. Organic certification is a broader standard that prohibits rBST use but also sets regulations for feed (e.g., non-GMO), pasture access, and synthetic pesticide use.

All milk naturally contains hormones, and the amount from added synthetic hormones is often debated. The FDA has deemed milk from rBST-treated cows safe, but some studies link increased IGF-1 levels to health risks, though evidence is not conclusive. Many consumers prefer to avoid synthetic hormones as a precaution.

The Non-GMO Project Verification confirms that FAGE's yogurts are produced according to their standards for avoiding genetically modified organisms. This includes ensuring the cows that provide the milk are fed non-GMO feed.

Check the packaging for labels stating 'rBST-free,' 'rBGH-free,' or 'No artificial growth hormones.' You can also opt for certified organic yogurt, as these standards prohibit synthetic hormones.

Countries like Canada, Australia, and all members of the European Union have banned the use of rBST. This is often due to concerns about animal health and welfare, and sometimes in response to consumer demand.
