Why Muscle Matters More as the Years Go By

Staying strong is one of the best investments in your long-term health. Muscle supports your metabolism, balance and your ability to stay active and independent — yet from around our late 30s onward, most adults gradually begin to lose it. The encouraging news: muscle is remarkably responsive to the right habits.

Adults gradually lose muscle from their late 30s onward — good habits can help slow it.
Muscle is built from amino acids; nine "essential" ones must come from your diet.
Resistance training plus adequate protein are the two most reliable levers.
Essential amino acid supplements are one option when food alone falls short.
The Science

Protein Quality — Not Just Quantity

Of the 20 amino acids involved in building muscle, nine are essential — your body can't make them, so they must come from your diet. But not all protein is used with the same efficiency: some is lost to digestion rather than going toward muscle.

Common Questions

Questions & Answers

At what age should I start thinking about muscle maintenance?

Earlier is better — muscle changes can begin subtly in your late 30s and 40s, so building good habits sooner helps preserve strength over time.

Can I get all my amino acids from food?

Many people can, especially with a varied diet including complete protein sources. Supplements are simply an option for those who find it hard to meet their needs through food alone.

Are amino acid supplements only for athletes?

No. Essential amino acids are relevant to anyone interested in maintaining muscle and strength — including older adults focused on healthy aging.

Do I need to exercise for amino acids to help?

Nutrition and activity work together. Amino acids provide the building blocks, while resistance training signals your body to use them.
