What is a complete protein?
Protein is a crucial macronutrient made up of smaller compounds called amino acids. While the human body can synthesize some of these amino acids, nine are considered "essential" because they must be obtained through our diet. A complete protein is a source that provides all nine of these essential amino acids in sufficient quantities. The nine essential amino acids are:
- Histidine
- Isoleucine
- Leucine
- Lysine
- Methionine
- Phenylalanine
- Threonine
- Tryptophan
- Valine
Incomplete protein sources, typically found in plant-based foods like grains or legumes, are low in one or more essential amino acids. However, combining different plant sources throughout the day can provide a complete amino acid profile. Animal products, like meat, eggs, and dairy, are naturally complete protein sources.
Ensure's protein sources and products
Ensure offers a variety of products, and the specific protein sources can differ depending on the formulation. In most of its standard, dairy-based products, Ensure uses high-quality protein from a blend of sources. These typically include milk protein concentrate, whey protein concentrate, and/or soy protein isolate. Both milk and soy are widely recognized as complete protein sources, which means they contain all the essential amino acids needed by the body.
Beyond the original formula, other product lines cater to specific nutritional needs:
- Ensure Max Protein: Contains 30 grams of a high-quality protein blend to support muscle health. Its protein sources include milk protein concentrate and calcium caseinate. This product boasts a Protein Digestibility Corrected Amino Acid Score (PDCAAS) of 1.0, signifying excellent quality protein.
- Ensure Complete: Offers 30 grams of high-quality protein along with balanced nutrition and other health benefits. It includes milk protein concentrate, calcium caseinate, and soy protein isolate.
- Ensure Plant-Based Protein: For those avoiding dairy and soy, this version uses a blend of fava bean and pea proteins. While these legume proteins are incomplete on their own, the blend is formulated to supply all the essential amino acids.
How Ensure's complete protein benefits your body
Consuming complete protein, whether from Ensure or other food sources, provides numerous benefits vital for maintaining a healthy and active lifestyle:
- Muscle Health: Protein is the building block of muscles, and the essential amino acids found in complete proteins are crucial for muscle protein synthesis, aiding in both muscle growth and repair. This is especially important for athletes and older adults who need to maintain muscle mass.
- Immune Function: Amino acids are essential for the production of antibodies and immune cells that help the body fight off infections. Products like Ensure Complete and Max Protein are often fortified with additional immune-supporting nutrients like zinc and vitamins C and E.
- Satiety and Metabolism: Protein is known for keeping you feeling full for longer by influencing hunger hormones. It also has a higher thermic effect than fats or carbohydrates, meaning your body burns more calories to digest it, which can help support a healthy metabolism.
- Tissue Repair: The body constantly breaks down and rebuilds tissues. Complete proteins supply the necessary materials for this process, supporting recovery from injuries, surgery, or illness.
Comparing Ensure products
Choosing the right Ensure product depends on individual health goals, whether you're aiming for general nutrition, higher protein, or weight gain. Below is a comparison of some popular options:
