Modern bars often incorporate additional components to enhance their nutritional impact and functional benefits. Dietary fiber, such as chicory root or soluble corn fiber, is frequently added to promote digestive health and increase feelings of fullness. Many bars are fortified with essential vitamins and minerals, bridging nutritional gaps and supporting overall metabolic functions. Other sophisticated formulations may include adaptogens for stress support, probiotics for gut health, or superfood extracts like spinach or kale powder for a micronutrient boost. These ingredients elevate the bar from a simple protein delivery system to a more holistic nutritional supplement.
