Is MSG Gluten-Free?

Monosodium glutamate, commonly known as MSG, has been a topic of debate and concern in the food industry for decades. As a flavor enhancer, MSG is widely used to elevate the taste of various dishes, from soups and sauces to snacks and processed foods. 

However, its reputation has been marred by persistent misconceptions and rumors, leading to questions about its safety and potential impact on health. 

One of the most common questions raised: is MSG gluten-free? or if it contains gluten, making it unsuitable for individuals with gluten sensitivities or celiac disease. 

In this article, we will delve into the world of MSG, explore its composition and usage, and address the crucial question: Is MSG truly gluten-free? Let’s separate fact from fiction and gain a better understanding of this controversial food additive.

What is MSG?

MSG, short for Monosodium Glutamate, is a flavor-enhancing food additive that has been utilized in the culinary world for over a century. It is a sodium salt of glutamic acid, which is an amino acid naturally found in certain foods like tomatoes, cheese, and mushrooms. 

The process of creating MSG involves fermenting starches or sugars from sources such as sugarcane, molasses, or tapioca. The resulting white, crystalline powder is soluble in water, making it easy to incorporate into a wide range of dishes. 

MSG earned its popularity due to its ability to enhance the savory taste of foods, often described as “umami,” which is considered the fifth basic taste, alongside sweet, salty, sour, and bitter. 

While MSG is commonly associated with Asian cuisines, it is prevalent in many processed and packaged foods worldwide. 

Despite its widespread usage, MSG has faced unwarranted criticism, with some individuals attributing adverse health effects to its consumption, which has led to numerous studies and investigations to assess its safety.

Role of MSG in food industry

In the food industry, MSG plays a crucial role as a flavor enhancer and taste amplifier. Its ability to heighten the savory taste in various dishes makes it a popular choice among chefs and food manufacturers. 

By adding MSG to foods, it intensifies and balances the existing flavors, creating a more satisfying and enjoyable eating experience. 

Additionally, MSG can help mask undesirable tastes and odors that may arise during food processing and storage. Its water-soluble nature allows it to dissolve easily in liquids, making it versatile and suitable for a wide range of culinary applications, including soups, sauces, marinades, dressings, snacks, and processed foods. 

The use of MSG enables food manufacturers to achieve consistent and desirable flavors in their products, ultimately enhancing the overall palatability and appeal to consumers.

Is MSG gluten-free? 

Yes, MSG is gluten-free. Monosodium Glutamate (MSG) is a flavor-enhancing food additive made from fermenting starches or sugars and contains no gluten. Gluten is a protein found in certain grains like wheat. Since MSG is derived from non-gluten sources, it does not contain gluten and is safe for consumption by individuals with gluten sensitivities or celiac disease.

Some food sources of MSG

MSG is a common taste amplifier used in various cuisines and processed foods. While it can be added separately to dishes, it also occurs naturally in certain foods. Here are some common food sources of MSG:


Tomatoes are naturally rich in glutamate, the amino acid that is the primary component of MSG. This is why tomatoes and tomato-based products, such as tomato sauce and ketchup, have a naturally savory and umami taste.


Several types of cheese, particularly aged cheeses like Parmesan, Roquefort, and Gouda, contain naturally occurring glutamate, contributing to their rich and savory flavors.


Mushrooms are another natural source of glutamate, and they are often used to add umami flavor to various dishes.

Seaweed and Kelp

Certain types of seaweed and kelp are high in glutamic acid, which can be extracted and used as a natural flavor enhancer.

Soy Sauce

Soy sauce is a common condiment in many Asian cuisines and contains naturally occurring glutamate, providing a savory taste to dishes.

Fermented Foods

Fermented foods like kimchi, sauerkraut, and certain pickled vegetables can have naturally occurring glutamate, contributing to their savory taste.

Processed and Packaged Foods

Many processed and packaged foods, such as chips, soups, snacks, and frozen meals, may contain added MSG to enhance their flavor.

Side effects of MSG on health

While the majority of people can consume MSG without any adverse effects, some individuals may experience side effects, commonly referred to as “MSG symptom complex” or “Chinese Restaurant Syndrome.” The common side effects include:

  1. Headaches: One of the most commonly reported symptoms is headaches, particularly in sensitive individuals.
  2. Flushing or Sweating: Some people may experience facial flushing or excessive sweating after consuming foods high in MSG.
  3. Nausea and Vomiting: In rare cases, MSG ingestion may lead to feelings of nausea and vomiting.
  4. Chest Pain or Heart Palpitations: Some individuals have reported experiencing chest pain or irregular heartbeats after consuming foods containing MSG.
  5. Tingling or Numbness: A few individuals have described feelings of tingling or numbness in certain body parts after consuming MSG-rich foods.

MSG alternatives 

For individuals who prefer to avoid or reduce their consumption of MSG or have sensitivities to it, there are several alternatives available to enhance the flavor of dishes. Here are some MSG alternatives:

Natural Umami-Rich Ingredients: Incorporate ingredients that naturally contain glutamate and provide umami flavor. Examples include tomatoes, mushrooms, soy sauce, fish sauce, aged cheeses like Parmesan, and certain seaweeds.

Nutritional Yeast: Nutritional yeast is a deactivated yeast product that has a cheesy, nutty flavor. It is a popular choice among vegans and vegetarians as a seasoning to add umami to dishes.

Tamari Sauce: Tamari is a type of soy sauce that is typically gluten-free and contains a rich umami taste. It can be used as a substitute for regular soy sauce, which often contains added MSG.

Anchovies and Anchovy Paste: Anchovies and anchovy paste can add a savory umami flavor to various dishes, such as pasta sauces and dressings.

Miso Paste: Miso is a fermented soybean paste commonly used in Japanese cuisine. It provides a deep, umami flavor to soups, marinades, and glazes.

Herbs and Spices: Certain herbs and spices, such as thyme, rosemary, and savory, can contribute to a savory flavor profile in recipes.

Dried Seaweed Flakes: Dried seaweed flakes, like nori or dulse, can be crumbled over dishes to add an umami taste.

Lemon or Lime Juice: The acidity of lemon or lime juice can brighten flavors and enhance taste in various recipes.


Does MSG cause bowel movements?

There is no direct evidence to suggest that MSG causes bowel movements. However, some individuals may experience digestive discomfort or changes in bowel habits after consuming MSG.

What does a reaction to MSG feel like?

Reactions to MSG, also known as “MSG symptom complex,” may include symptoms such as headaches, facial flushing, and sweating. Some individuals may experience nausea, chest pain, or tingling sensations in certain body parts.

Does wheat have MSG?

No, wheat does not naturally contain MSG. Monosodium Glutamate (MSG) is derived from fermenting starches or sugars and is not present in wheat. However, certain wheat-based products may have added MSG as a separate ingredient for flavor enhancement.

How to flush msg out of your body?

MSG is metabolized like any other amino acid in the body and does not require any special flushing process. It is broken down and excreted naturally through normal bodily functions. Staying well-hydrated and consuming a balanced diet with plenty of fruits, vegetables, and fiber can support the body’s natural detoxification processes.


MSG is a flavor enhancer commonly used in the food industry to elevate the savory taste of various dishes. Despite being associated with certain side effects in sensitive individuals, MSG is generally considered safe for consumption by the majority of the population. 

Importantly, MSG is gluten-free, making it suitable for individuals with gluten sensitivities or celiac disease. Understanding the facts about MSG and its gluten-free status allows consumers to make informed choices and enjoy its flavor-enhancing properties without unnecessary concern.
