Every time we reach for a snack, a supplement, or even a seemingly healthy packaged product, we are surrounded by a long list of ingredients, many of which are hard to pronounce or understand. One such ingredient that often appears on labels, yet remains poorly understood by many consumers, is magnesium salts of fatty acids, also known as E470b. Despite the technical name, this compound is actually quite common in food and supplement production, and it serves very practical purposes.
But with the rise of clean eating and growing concerns about additives, many are asking: Is it safe? Does it contribute anything to our health?
In this article, we will take a closer look at what (magnesium salts of fatty acids) E470b really is, how it is used in everyday foods/products, what the research says about its safety, and whether there are important reasons to be cautious. We will also address common myths and questions, helping you make more informed choices when shopping for food or supplements.
What Are Magnesium Salts of Fatty Acids?
At its core, magnesium salts of fatty acids are chemical compounds formed when magnesium reacts with fatty acids, which are natural substances found in both plants and animals. While the term may sound like a complex chemical formula, its role is surprisingly straightforward. In the food industry, these salts are highly valued for their ability to improve the physical properties of products.
They function as emulsifiers, allowing ingredients that normally would not mix like water and oil to blend seamlessly. Additionally, they act as anti-caking agents, preventing powders from clumping together during production, storage, or transportation. In supplements, they improve the flow of powdered ingredients, making it easier to produce tablets and capsules that are uniform in size and texture.
Despite the presence of magnesium in chemical form, it is important to remember that magnesium salts of fatty acids are not a significant source of dietary magnesium. Their primary purpose is functional rather than nutritional, ensuring that products look good, feel smooth, and maintain their intended structure.
Where Can You Find Magnesium Salts?
Magnesium salts of fatty acids are more common than most people realize. In the case of food products, they can be found in everything from bakery items like cookies and bread to ice cream, margarine, and even processed meats. They are used to improve texture, prevent separation, and extend shelf life.
For example, in margarine, E470b helps maintain a consistent spreadable texture, while in ice cream it can prevent crystallization and improve creaminess. In supplements and pharmaceuticals, magnesium salts are even more prevalent.
Tablets, capsules, and powdered formulations rely on E470b to ensure smooth production, prevent sticking in machinery, and maintain consistent dosage. If you look closely at the labels, you may see it listed as E470b, magnesium stearate, or magnesium salt of fatty acid, which can be confusing for those who don't regularly read labels.
Awareness of these labels is important, especially for those who follow a clean eating policy or want to reduce their intake of processed additives.

Magnesium Salts and Health – Facts and Controversies
The safety and health implications of magnesium salts of fatty acids have been discussed extensively in both scientific literature and popular health media, and opinions are varied.
On the one hand, regulatory agencies such as the European Food Safety Authority (EFSA) and the World Health Organization (WHO) consider E470b to be safe for consumption within typical levels used in food and supplements.
Research suggests that, in these quantities, it does not pose a significant risk to health. Some potential benefits have also been identified. For example, magnesium salts may enhance the absorption of fats and fat-soluble vitamins, such as vitamins A, D, E, and K. This can theoretically support nutrient uptake in the diet.
However, it is crucial to understand that the amount of magnesium present in these compounds is very small and not nutritionally relevant.
On the other hand, some critics have expressed concerns. Some studies and anecdotal reports suggest that taking excess magnesium salts, especially in supplements, may have minor negative effects, such as slightly reducing the absorption of other nutrients.
There is also a theoretical risk that, over time, accumulation of the compound in the gut could interfere with digestive processes or, in sensitive individuals, mildly affect the immune system.
Furthermore, people with specific metabolic conditions may need to be more cautious, although there is no strong evidence linking normal consumption levels of E470b to serious health problems.
Overall, the scientific consensus is that magnesium salts of fatty acids are generally safe, but the controversy highlights a larger issue: consumers often lack information about the additives in their foods and supplements.
Reading labels and understanding the role of each ingredient can empower individuals to make choices that align with their health goals and dietary preferences.
Magnesium Stearate vs Magnesium Salts – Are They the Same?
Magnesium stearate is the most widely recognized form of magnesium salts in supplements and pharmaceuticals. It is a specific compound formed by combining magnesium with stearic acid, a type of fatty acid. While the terms “magnesium stearate” and “magnesium salts of fatty acids” (E470b) are often used interchangeably, E470b can include other fatty acids as well, making it a broader category.
Functionally, both magnesium stearate and E470b serve the same purpose: to improve flow, prevent caking, and facilitate tablet production. The difference lies primarily in the chemical composition and labeling, which can sometimes confuse consumers trying to avoid certain additives.
In reality, both forms are widely studied and generally considered safe for human consumption when used in regulated amounts.

Expert Opinions and Legal Regulations
Experts in food science and nutrition generally agree that magnesium salts of fatty acids do not pose a health risk under normal usage. They are approved for use in food and supplements by global regulatory bodies, including EFSA, FDA, and WHO, which monitor permissible levels to ensure safety.
Despite this, many health-conscious consumers prefer products that follow the Clean Label philosophy, which emphasizes minimal additives, transparent ingredients, and natural alternatives whenever possible. Choosing supplements or foods with fewer artificial additives may provide peace of mind and align with a preference for more natural products.
Ultimately, understanding the purpose of E470b and its regulated use allows consumers to make informed decisions without unnecessary fear or misunderstanding.
Conclusion & Consumer Recommendations
Magnesium salts of fatty acids are a practical and widely used ingredient in food and supplements. Their primary role is to improve texture, prevent clumping, and aid in manufacturing consistency. While they are generally considered safe and do not provide a meaningful source of magnesium, some consumers choose to limit their intake for personal or dietary reasons.
A balanced approach is recommended: read labels carefully, choose products that prioritize transparency, and consult a nutritionist if you have concerns about interactions or sensitivities. Awareness, rather than avoidance, is key.
By understanding what magnesium salts of fatty acids are and how they function, consumers can make choices that support both convenience and health without unnecessary worry.
