Frequently Asked Questions
Do all BIG 100 flavors have the same protein content?
Protein content ranges from 30-32g depending on the specific flavor — Super Cookie Crunch delivers 32g, while flavors like Crispy Apple Pie deliver 30g. Macros (calories, fat, sugar) also vary slightly by flavor due to different flavor-specific ingredients. Check the specific flavor's nutrition label for exact figures.†Is BIG 100 gluten free?
Yes — BIG 100 bars are labeled gluten free across the flavor lineup.†Can BIG 100 actually replace a meal?
Yes, functionally — at approximately 400 calories with 30-32g protein and a full 18-vitamin-and-mineral panel, BIG 100 is formulated with genuine meal-replacement nutrition rather than just a protein snack profile. Use in conjunction with an intense daily exercise program and a balanced diet including adequate total caloric intake for your goals.†What allergens does BIG 100 contain?
BIG 100 bars contain milk, egg, soy, peanut, and tree nut (almond) ingredients — a broad allergen profile due to the multi-source METAMYOSYN protein blend and various flavor components like almond butter and peanut flour. Individuals with any of these allergies should not consume this product.†
