Vitamins:
Vitamins are organic compounds crucial for numerous bodily functions. They can support immune function, energy production, and overall health. Nutrition bars enriched with vitamins like B-complex or vitamin C can provide additional health benefits. A well-rounded nutrition bar should ideally include various vitamins, helping to meet daily recommended values and support overall wellness. -
Minerals:
Minerals are inorganic elements that play vital roles in various bodily processes, including muscle function and hydration. Common minerals include calcium, potassium, and magnesium. Nutrition bars can be fortified with these minerals, often through the inclusion of nuts and seeds or through added supplements. Aim for bars that provide key minerals to complement a balanced diet and support overall health.
