Casein and Whey in Muscle 5

Inspired by Nature and Designed by Science

Muscle 5 is a unique health supplement that contains a blend of muscle-building nutrients, each scientifically proven to enhance lean mass, strength, and performance, but in different, complimentary ways.

Two of the five key ingredients in Muscle 5, whey protein isolate (Fonterra WPI 895-I) and milk protein isolate (Fonterra MPI 4900), are low lactose proteins from New Zealand that are specifically formulated by our scientists to supply a time-dependent release of essential amino acids (EAAs) to sustain a net positive protein balance for optimized muscle growth.

1. Fast-Acting Whey: Immediate Muscle Benefits

The WPI in Muscle 5 is a fast-acting protein component that is easily digested and provides a rapid spike in EAAs of high anabolic potential known as branched-chained amino acids. Over the last 30 years, research has consistently shown that intake ≥ 20 g of whey enhances muscle protein synthesis (MPS) at rest and post exercise. It is also well-known that whey augments lean mass and strength gains in both young and old individuals that are resistance training. Theoretically, these benefits may be further enhanced when whey is combined with other supplements, such as creatine monohydrate or casein.

2. Slow-Acting Casein: Sustained Muscle Benefits

In addition to the fast-acting WPI component, Muscle 5 contains milk protein isolate that comprises of both whey (20%) and micellar casein (80%), which is a slow-acting protein with a slightly delayed digestion and plasma amino acid profile, making it a great compliment to WPI. Research studies have repeatedly shown that intake of casein results in a lower but sustained spike in plasma EAAs and improves protein turnover by enhancing long-term MPS and reducing whole-body protein breakdown.

3. Whey and Casein Ratio in Muscle 5 – Inspired by Nature

Furthermore, the combination of fast-acting WPI and slow-acting MPI in a whey-to-casein ratio optimal for human development (e.g., 60:40), makes Muscle 5 a unique supplement on the market, which is truly inspired by nature for improved digestibility and muscle growth.

Why Muscle 5?

One scoop of StayAbove Nutrition™’s multi-nutrient product Muscle 5 contains 40 grams of high-quality whey and casein proteins from New Zeeland and additional ingredients for optimized muscle growth (vitamin D, calcium, and creatine).

True to the motto of Stay Above Nutrition (“Built and Backed by Science”), Muscle 5 is designed by scientists and has been proven in several, independent clinical trials to enhance muscle mass, strength, and performance.

Muscle 5 is currently being used by professional athletes in the CFL, elite runners, and by health conscious individuals across all North America.
