Why muscle matters

Strength is what keeps life yours.

Muscle helps us stand up, carry the shopping and keep moving. Age, illness and inactivity can reduce muscle and strength. Getting enough protein and staying active help maintain muscle.

Evidence and sources

Everyday movement runs on muscle, and muscle and strength decline with age, illness and inactivity.1 2 Getting enough protein and staying active help maintain muscle.4 7

Muscle loss can make everyday tasks harder.

More muscle tissue

Less muscle tissue

Two side-by-side cross-sections of thigh muscle on the same bone and outer contour: more muscle tissue on the left, less on the right.
  • Muscle is the striated tissue that fills most of the cross-section.
  • Fat is the softer outer layer under the skin.
  • Bone is the dense core at the center.

How protein supports muscle

The first product

An unflavored powder, in a sachet.

Made to be added to the food already on the plate, not to replace it. It is a medical food for the dietary management of sarcopenia associated with chronic disease, used under a physician’s supervision.

What is in it

Whey protein, HMB and vitamin D.

Whey protein provides the amino acids muscle is made of, HMB is derived from the amino acid leucine, and vitamin D supports muscle function.

Why these three

Built around the life someone already has.

CORUS starts from the foods, routines and preferences an older adult already has, and designs clinical nutrition to fit them. Clear information for the people who help, and for the clinicians who supervise.
