How Much Protein Do We Really Need Every Day?

Protein is an essential nutrient needed for building and maintaining muscles, bones, skin and many other tissues in the body. It is also responsible for the production of enzymes, hormones and antibodies.

But how much protein do we actually need each day? The answer to this question depends on various factors, such as age, gender, level of physical activity and individual needs.

Protein needs by age

Protein requirements vary throughout life. Here are some guidelines for daily protein needs by age group:

  • Infants (1-3 years): 13-19 grams
  • Children (4-8 years): 19-34 grams
  • Youth (9-13 years): 34-52 grams
  • Youth (14-18 years): 46-52 grams (boys), 46-50 grams (girls)
  • Adult (19+ years): 46-56 grams (females), 56-81 grams (males)

Protein requirements after physical activity

Protein requirements may also depend on physical activity. People who exercise regularly or do strenuous physical work may need more protein to aid in muscle building and recovery.

It is recommended to consume around 1.2-2 grams of protein per kilogram of body weight per day when active. This may vary depending on individual goals and training intensity.

protein sources

There are many different sources of protein that can be included in a balanced diet. Here are some protein-rich foods:

  • Lean meats (chicken, turkey, beef)
  • fish and seafood
  • Dairy products (milk, yogurt, cheese)
  • Legumes (beans, lentils, chickpeas)
  • Tofu and other soy products
  • eggs
  • nuts and seeds

It's important to consume a variety of protein sources to get a balanced mix of essential amino acids.


The daily protein requirement depends on various factors, such as age, gender and physical activity. Infants, children and teenagers require less protein than adults. People who are active or exercise may want to consume more protein to help build muscle. A balanced diet with a variety of protein sources is crucial to meet protein needs.
