Final word

When combined with resistance training, protein intakes above the current RDA can support muscle building.

The best way to meet your daily protein needs is by consuming lean meat, fish, beans, nuts, and legumes.

Since the optimal amount of protein a person needs depends on age, health status, and activity level, consider speaking with a healthcare provider or a registered dietitian to discuss how much protein is suitable for you.
