The Power of Protein: A Lifelong Fuel for Athletes and Beyond

Protein, often hailed as the building block of life, plays a crucial role in maintaining and enhancing health across all stages of life. From infancy to old age, and particularly for athletes, the benefits of adequate protein intake are undeniable. In this blog, we'll explore the diverse advantages of protein consumption across the age spectrum, shedding light on its significance for individuals pursuing an active lifestyle.

Infancy and Childhood:

In the early stages of life, protein is instrumental in supporting the rapid growth and development of tissues, organs, and muscles. Breast milk, recognized as the gold standard for infant nutrition, is naturally rich in proteins that facilitate the formation of a robust immune system and contribute to optimal brain development. For infants who are not breastfed, specialized infant formulas are designed to provide an appropriate balance of proteins.

During childhood, protein remains essential for growth spurts, bone development, and overall physical well-being. It supports the formation of enzymes, hormones, and antibodies, ensuring that young bodies have the necessary tools to navigate the challenges of growth and development.

Adolescence and Young Adulthood:

As individuals transition into adolescence and young adulthood, protein continues to be a key player in supporting physical development. This is a critical time for those engaged in sports and fitness activities, as the demand for protein increases to build and repair muscles. Adolescents involved in sports benefit not only from muscle development but also from improved bone density, as protein aids in the absorption of essential minerals like calcium.

Young adults pursuing athletic endeavors can leverage protein intake to enhance performance, support recovery, and achieve their fitness goals. Whether through natural food sources or supplements, the right balance of protein is crucial for sustaining energy levels and promoting muscle repair after intense workouts.


In adulthood, the importance of protein extends beyond growth and development. It becomes a key component in maintaining muscle mass, supporting metabolic functions, and preserving overall health. Protein also plays a role in weight management, as protein-rich diets contribute to a feeling of fullness, potentially reducing overall calorie intake. Adequate protein intake is particularly beneficial for active adults as it serves as a fundamental element in post-exercise recovery, aiding in the repair of muscle fibers and reducing the risk of injury.

Elderly Population:

As individuals age, maintaining muscle mass and strength becomes increasingly important for overall health and independence. Protein becomes a crucial ally in combating age-related muscle loss, known as sarcopenia. Older adults, including athletes in their golden years, can benefit from increased protein intake to support muscle maintenance, bone health, and overall vitality.

Protein Intake Recommendations:

The American College of Sports Medicine (ACSM) provides general guidelines for protein intake, especially for individuals engaged in regular physical activity and exercise. Keep in mind that guidelines may have been updated since then, so it's always a good idea to check for the latest information.

As of my last update, ACSM recommended the following protein intake guidelines for athletes and active individuals:

  • For sedentary individuals, the MINIMUM recommended dietary allowance (RDA) for protein is 0.8 grams per kilogram of body weight per day.

  • For those engaging in regular exercise, the protein needs are higher, ranging from 1.6 to 2.2 grams per kilogram of body weight per day. (2.2g/kg bodyweight =1g/pound bodyweight).

  • Distributing protein intake throughout the day is generally recommended.

  • Consuming protein-rich meals and snacks in close proximity to exercise (before and after) may be beneficial for muscle protein synthesis and recovery.


Considering ~1g protein per pound bodyweight, it can be difficult for many to achieve adequate protein intake without supplementation. Protein supplements can be purchased almost anywhere, from gyms and nutritional shops, to grocery stores and gas stations. It is important to note that the FDA does not monitor supplements and that not all products are equal in terms of safety, quality and efficacy.

At Altius, we recommend and distribute Thorne Nutritional Products, which are NSF Certified for Sport. NSF certification is a rigorous third party supplement testing process that verifies that the contents of the product match what is on the product’s label and that the products do not contain any banned substances. If you are looking for a high quality and effective protein, you can purchase online or purchase at our facility!


Protein stands as a nutritional powerhouse offering a multitude of benefits across the age spectrum. From supporting growth and development in infancy to enhancing athletic performance and recovery in youth, adolescents and adults to mitigating muscle loss in old age, its significance cannot be overstated. Athletes, in particular, can harness the power of protein to optimize their training, aid recovery, and achieve peak physical condition. Through natural dietary sources or carefully chosen supplements, integrating an appropriate amount of protein into one's diet is a key step towards a healthier, more active life.
