Calcium is vital during the teenage years for building strong bones and supporting overall health. Teenagers need between 1,000 and 1,300 mg of calcium daily to support growth and development. If teens don’t get enough calcium through their diet, their bodies will take it from their bones, which can weaken them over time.
Why is Calcium Important for Teenagers?
Calcium is the most abundant mineral in the body, with 99% stored in bones and teeth. It’s essential for:
- Bone health: Calcium is the primary building block of bone, and adequate intake during adolescence is crucial for achieving peak bone mass.
- Muscle function: Calcium helps muscles contract, including the heart.
- Nerve transmission: It plays a role in transmitting nerve impulses throughout the body.
- Blood clotting: Calcium is necessary for blood to clot properly.
- Hormone secretion: It helps regulate the secretion of hormones and the function of enzymes.
How Much Calcium Do Teenagers Need Per Day?
The Food and Nutrition Board of the U.S. National Academy of Sciences recommends that teenagers consume 800 to 1,300 mg of calcium daily. This is a higher requirement than adults, who need 1,000 to 2,000 mg of calcium daily.
What are the Best Food Sources of Calcium for Teens?
- Dairy products: Milk, cheese, and yogurt are excellent sources of calcium.
- Leafy green vegetables: Broccoli, turnips, and collard greens also contain calcium.
- Seafood: Salmon and sardines are good sources.
- Fortified foods: Some foods, like cereals and plant-based milk alternatives, are fortified with calcium.
What Factors Affect Calcium Absorption in Teens?
Several factors can affect how well the body absorbs calcium:
- Vitamin D: Vitamin D is essential for calcium absorption.
- Phosphorus: Optimal ratios of phosphorus to calcium in the diet help with calcium utilization.
- Dietary intake: Previous and current calcium intake levels affect absorption.
What Happens if Teenagers Don’t Get Enough Calcium?
If teenagers don’t get enough calcium, their bodies will take calcium from their bones to maintain normal blood levels. Over time, this can lead to weakened bones and increase the risk of osteoporosis later in life. Severe calcium deficiency can cause hypocalcemia, leading to numbness, tingling, muscle spasms, and aches.

What are the symptoms of calcium deficiency in teenagers?
Symptoms of severe calcium deficiency (hypocalcemia) include numbness and tingling around the mouth and fingertips, as well as muscle aches and spasms. However, a clinically detectable deficiency is relatively rare and usually caused by a deficiency of parathyroid hormone or vitamin D.
Can teenagers get enough calcium from their diet alone?
Yes, teenagers can get enough calcium from their diet by consuming calcium-rich foods like dairy products, leafy green vegetables, and fortified foods. However, some teenagers may need to take calcium supplements if they cannot meet their daily requirements through diet alone.
Are there any risks associated with too much calcium intake in teenagers?
While it’s essential to get enough calcium, excessive intake can also be harmful. High doses of calcium supplements may cause constipation and may interfere with the absorption of other minerals. It’s best to get calcium from food sources whenever possible and to talk to a healthcare professional before taking high-dose supplements.
Ensuring teenagers get enough calcium is crucial for building strong bones and supporting overall health. Encourage teens to consume a variety of calcium-rich foods and consider vitamin D supplementation to optimize calcium absorption.
