Some people lose muscle strength or mass as they age and find daily activities more difficult. However, changes in later life vary from person to person. Fatigue and mood changes can have many causes and should not automatically be attributed to muscle or hormone levels.
Muscles support daily activity, but do not measure a person’s age
Maintaining the ability to move and carry out everyday tasks matters for health and independence. The World Health Organization notes that physical activity can support physical and mental health. Strength exercises adapted to a person’s ability can be part of maintaining strength and balance. If you have heart disease, chronic pain, or a history of falls, ask a healthcare professional for advice before starting a demanding program.
What “anti-aging hormone” claims can and cannot show
The phrase “anti-aging hormone factory” is a metaphor; it does not establish that increasing a particular hormone will slow aging or treat fatigue. The health references below support general benefits of physical activity and nutrition in older adults, but they do not establish that raising a hormone can reverse aging. Do not use this phrase as a reason to buy hormones or supplements for self-treatment.
