Exposing MSG’s Hidden Names and Defending Your Health

Written by Dr Steven L. Robertson on August 30, 2025. Posted in Current News

Monosodium glutamate (MSG) is one of the most controversial food additives on the market

While it has long been used as a flavor enhancer—commonly associated with the “umami” taste—concerns remain about its impact on health.

MSG is considered an excitotoxin, meaning it overstimulates nerve cells to the point of damage or even death of the cells.

This overstimulation can create cravings for foods containing it, making MSG a hidden driver of overeating and food dependency.

More clinically an excitotoxin is similar to cocaine… (no wonder Chick Fil A needs a traffic cop for their drive through).

Why the Concern About MSG?

According to Battling the MSG Myth, MSG is not just a seasoning—it is a neurological disruptor.

The author explains how MSG is hidden under many different names, making it difficult for consumers to recognize. This hidden labeling has allowed MSG to enter nearly every aisle of the grocery store, from soups and snacks to protein powders and even “health” foods.

Foods That Always Contain MSG

When reading ingredient labels, MSG may not appear under its common name. Instead, manufacturers use alternate terms that disguise its presence. If you see any of these on a label, the product contains MSG:

• Monosodium glutamate
• Monopotassium glutamate
• Glutamate
• Glutamic Acid
• Calcium Caseinate
• Sodium Caseinate
• Hydrolyzed Vegetable Protein (HVP)
• Hydrolyzed Plant Protein (HPP)
• Autolyzed Plant Protein
• Autolyzed Yeast
• Yeast Extract
• Yeast Food or Nutrient
• Textured Protein
• Gelatin

Foods That Often Contain MSG

Some ingredients may not always contain MSG but are frequently processed in a way that results in free glutamates. Products made with the following should be approached with caution:

• Malted Barley / Barley Malt
• Malt Extract or Flavoring
• Maltodextrin
• Caramel Flavoring
• Stock / Broth / Bouillon
• Carrageenan
• Whey Protein or Whey Protein Isolate
• Soy Sauce or Extract / Soy Protein / Soy Protein Isolate
• Cornstarch / Citric Acid (from corn)
• Modified Food Starch
• Rice Syrup / Brown Rice Syrup / Corn Syrup solids
• Ultra-pasteurized or Enzyme-modified products
• Protein-fortified milk or enriched foods
• Flavors, Flavoring, or Reaction Flavors
• Spices and Seasonings blends
• Gums and Dough Conditioners
• Yeast Nutrients

Yes when you read labels you’ll be shocked to find msg is in almost everything…it naturally occurs in tomatoes and parmesan cheese maybe that’s why pizza is so good;)

These hidden sources of MSG are often present in foods marketed as “low-fat,” “healthy,” or “natural,” which makes careful label reading especially important.

Breaking Free from Hidden MSG

Battling the MSG Myth emphasizes that the key to avoiding MSG is education. By learning the hidden names and recognizing common sources, you can protect yourself from this excitotoxin.

The book also highlights healthy alternatives, showing how easy it can be to replace MSG-laden foods with natural seasonings, fresh herbs, and whole foods found in most supermarkets.

MSG is more than a simple flavor enhancer—it can act as a neurotoxin and create cravings that encourage overeating. Unfortunately, food manufacturers often hide it under deceptive names, making it hard for consumers to know what they are truly eating.

By becoming aware of these hidden names and choosing healthier alternatives, you can take control of your diet and protect your long-term health.

According to nutritional research and expert recommendations:

• Daily magnesium needs for adults typically range between 400–420 mg for men and 310–320 mg for women (U.S. National Institutes of Health).
• However, when dealing with high levels of dietary excitotoxins such as MSG, some practitioners and health advocates recommend 600–900 mg per day, divided into smaller doses throughout the day for better absorption and tolerance.

Forms of Magnesium Often Recommended:

• Magnesium Glycinate – highly absorbable, gentle on the stomach.
• Magnesium Malate – supports both brain and muscle energy.
• Magnesium Threonate – shown in studies to cross the blood-brain barrier effectively.

• Always increase magnesium gradually to avoid digestive upset.
• People with kidney disease or other medical conditions should consult their healthcare provider before using higher doses.
• Balancing magnesium with adequate hydration and other minerals (like calcium and potassium) helps optimize its protective effects.
• A pinch of Celtic Sea Salt before bed is a great way to keep magnesium and other essential minerals in your system. (it also helps with the quality of sleep)

By ensuring adequate magnesium intake, you may help buffer your nervous system against MSG’s excitotoxic effects while supporting overall brain and muscle health.
