What is Protein?

Proteins are large, complex molecules made up of amino acids, which are the building blocks of muscle, enzymes, and various cellular structures. They can be sourced from both animal and plant origins, commonly derived from meat, dairy, legumes, soy, and grains.

Proteins are essential for building and repairing tissues, supporting metabolic reactions, and maintaining healthy skin, hair, and nails. They are used in food products to boost nutritional content and may be present in sports nutrition products for muscle-building purposes. The health evidence suggests they are critical for maintaining overall health, though the required amounts can vary based on factors like age, activity level, and specific health goals.

When you see protein listed on a product label, consider whether it fits your dietary needs, especially regarding the source, as it can be animal-based or plant-based, affecting its suitability for certain diets.
