Explainer
In plain language
This group covers processed protein ingredients: caseinates, which are milk proteins treated with calcium or sodium, and textured or isolated plant proteins like textured vegetable protein and soy protein isolate. They are used to boost protein content, improve texture, and bind ingredients in bars, powders, and meat substitutes. They are concentrated forms of proteins that also occur in ordinary dairy and soy foods.
Assessment
Why it is flagged
Because these are broken-down and concentrated proteins, they contain higher levels of free glutamate, the same compound that gives MSG its savory taste, than the whole foods they come from. Some people who report sensitivity to added glutamates track these ingredients for that reason. The evidence that free glutamate from food causes symptoms in the general population is weak, and controlled studies have generally not confirmed a consistent effect, so this is contested rather than established. Regulators treat caseinates and textured proteins as ordinary food ingredients, not additives of concern. Clear Label flags them at low severity so users curious about glutamate sensitivity can see them and test their own patterns.

Where it commonly shows up
- Protein bars and protein powders
- Meat analogs and veggie burgers
- Non-dairy creamers
- Processed cheese products
- Nutrition shakes and meal replacements
- Some baked and frozen convenience foods
Practical
Reading the label
Watch for calcium caseinate, sodium caseinate, textured vegetable protein, TVP, soy protein isolate, and soy protein concentrate. Caseinates are milk-derived, so they matter for dairy allergies even though they can appear in products marketed as non-dairy.
Alternatives
If you want to avoid it
Some people who want to limit added free glutamates choose protein from whole foods like eggs, plain dairy, beans, or minimally processed protein powders with shorter ingredient lists. Comparing bars and shakes side by side often reveals simpler options.
FAQ
Common questions
Do these proteins contain MSG?
They are not MSG, but processing them releases free glutamate, the same compound found in MSG. That is why people watching for added glutamates sometimes track them.
Are caseinates dairy-free?
No. Caseinates are made from milk protein, so they are not suitable for a dairy-free or vegan diet even when they appear in products labeled non-dairy.
Is glutamate sensitivity real?
Some people report symptoms they link to added glutamates, but controlled studies have not consistently confirmed an effect in the general population. It is exactly the kind of personal pattern worth testing in your own logs.
