Quick take
The useful answer in 30 seconds
- Whey and casein are milk-derived ingredients.
- Plant-based does not automatically mean free from every allergen.
- Retail pages and formulas can change, so verify the exact package.
Where allergen information appears
Look for a clearly marked allergen statement, the ingredient list and any shared-equipment or facility notice. The placement and required wording can differ by market.
A product can be vegan and still carry a facility statement for an allergen. Treat those lines as separate pieces of information.
Common protein sources and allergen questions
Whey and casein come from milk. Soy protein relates to soy allergen labeling. Pea, rice and seed proteins may suit some shoppers but still require a complete label check for added ingredients and cross-contact statements.
| Protein source | Label check |
|---|---|
| Whey or casein | Milk ingredient and allergen statement |
| Soy | Soy declaration and blend ingredients |
| Pea or rice | Added flavors, gums and facility statement |
| Seed blends | Specific seed sources and other allergens |
When to stop and ask for professional guidance
If you have a diagnosed allergy or a serious reaction history, do not rely on a comparison summary. Confirm the current manufacturer and retailer information and seek advice from an appropriate healthcare professional.
