Commercial protein bars and supplements
Commercial protein bars and supplements are convenient, pre-packaged snacks designed to provide a concentrated source of protein, often marketed for fitness, meal replacement, or on-the-go nutrition. They typically feature protein isolates (like whey, soy, or pea) as the primary ingredient, combined with sweeteners, binders, and flavorings. Originating from the sports nutrition industry, they are now ubiquitous in mainstream grocery stores and pharmacies worldwide.
