Recommended Citrate Intake for Teenagers: A Comprehensive Guide

Magnesium is an essential mineral that supports hundreds of biological processes in the body, from nerve signaling and muscle function to energy production and digestion. Yet studies show that many kids fall short of the recommended intake, especially picky eaters and those following processed, low-fiber diets. This article delves into the importance of magnesium, particularly in the form of citrate, for teenagers, exploring recommended intakes, benefits, and potential risks.

Why Magnesium Matters for Teenagers

Magnesium is involved in more than 300 biochemical reactions in your body and is crucial for maintaining good health. It plays a vital role in:

Energy Metabolism: Magnesium is essential for energy metabolism
Protein Synthesis: Magnesium is essential for protein synthesis.
Brain Function: It also contributes to proper brain function.
Bone Health: Magnesium also contributes to proper bone health.
Heart and Muscle Activity: Magnesium also contributes to proper heart and muscle activity.

Teenagers, undergoing rapid growth and development, have increased magnesium needs. Insufficient magnesium intake can lead to various health issues, making it crucial to understand and address their specific requirements.

Recommended Daily Allowance (RDA) of Magnesium

The table below shows the recommended daily allowance (RDA) or adequate intake (AI) of elemental magnesium for adults, infants, and children. This includes magnesium from the food and any supplements you may be taking.

The RDA for magnesium is 310-420 mg for adults, depending on age and sex. For people over 18 years of age who are pregnant, the requirements are increased to 350-360 mg per day.

Teenage Males (14-18 years): The RDA for magnesium is 410 mg.
Teenage Females (14-18 years): The RDA for magnesium is 360 mg.

It's important to note that these are general guidelines. Individual needs may vary based on factors such as activity level, diet, and underlying health conditions.

Magnesium Citrate: A Beneficial Form

Magnesium supplements for kids come in several forms, but not all are created equal. Magnesium citrate is one of the most bioavailable forms of magnesium, meaning it is easily absorbed by the body. It is formed by combining magnesium with citric acid, a natural acid found in citrus fruits.

Benefits of Magnesium Citrate

Improved Absorption: Magnesium citrate is generally better absorbed than other forms of magnesium, such as magnesium oxide.
Constipation Relief: Some types of magnesium supplements are commonly used to help relieve constipation, including magnesium citrate. Magnesium citrate works by pulling water into your intestines, which adds water, bulk, and weight to your stool. This can help soften your stool and help ease its passage.
Muscle Function: Magnesium is crucial for muscle function, and adequate intake can help prevent muscle cramps and spasms, which may be beneficial for active teenagers.
Mental Health: Magnesium deficiency has been linked to depression. In fact, taking a magnesium supplement may improve depressive symptoms in some people.

Magnesium and Calcium: Partners in Bone Health

Calcium is a mineral that is important for strong bones and a healthy body throughout your life. A healthy diet is the best way to get the calcium you need. But calcium supplements may be an option if you don't get enough from your diet. The benefits of calcium include maintaining strong bones and helping the muscles, heart and nerves work as they should.

To absorb calcium, your body also needs vitamin D. Some foods naturally contain small amounts of vitamin D, such as canned salmon with bones, tuna and egg yolks. You also can get vitamin D from foods fortified with the vitamin. The recommended amount of vitamin D for most adults is 600 international units or 15 micrograms a day. Spending time in the sun also helps the body make vitamin D, even when you wear sunscreen.

Magnesium plays a crucial role in calcium absorption and utilization. A proper balance of magnesium and calcium is essential for optimal bone health. Magnesium helps regulate calcium transport and influences the activity of vitamin D, which is necessary for calcium absorption.

Dietary Sources of Magnesium

Still, many kids don’t hit their targets through food alone, especially if they’re picky eaters or have allergies. Encouraging teenagers to consume magnesium-rich foods is a great way to meet their daily requirements. Good sources of magnesium include:

Leafy Green Vegetables: Spinach, kale, and collard greens are excellent sources of magnesium.
Nuts and Seeds: Almonds, cashews, pumpkin seeds, and flaxseeds are rich in magnesium.
Legumes: Beans, lentils, and chickpeas are good sources of magnesium.
Whole Grains: Brown rice, quinoa, and oats provide magnesium.
Dark Chocolate: A delicious way to get some extra magnesium!
Dairy products: Milk, yogurt, cheese and other dairy products.
Fish with soft bones: Fish with soft bones you can eat, such as sardines and canned salmon.

Magnesium Supplements: When Are They Necessary?

While obtaining magnesium through diet is ideal, supplements may be necessary in certain situations. If a teenager has a magnesium deficiency, a healthcare professional may recommend magnesium supplements.

Dosage of Magnesium Citrate

The standard dose for magnesium citrate is 240 milliliters (mL) per day, which can be mixed with water and taken orally.

Considerations for Supplementation

Consult a Healthcare Professional: It’s important to speak with a healthcare professional before taking any supplements.
Magnesium Toxicity: Exceeding the recommended intake may cause magnesium toxicity.
Drug Interactions: Calcium supplements may interact with some medicines. These may include antibiotics, lithium, HIV inhibitors and thyroid hormone treatments. Ask your healthcare professional before taking calcium supplements if you take any medicine.

Potential Benefits of Magnesium Supplementation

Improved Sleep: A limited number of studies have studied the effects of magnesium supplements on sleep quality, making it difficult to recommend a specific daily dose. However, a 2021 review found that older adults with insomnia who took between 320-729 mg of magnesium per day from magnesium oxide or magnesium citrate were able to fall asleep faster compared to a placebo.
Blood Sugar Regulation: People with type 2 diabetes may be more likely to have low magnesium levels. This is because high blood sugar levels may increase magnesium loss through urine, causing low magnesium levels in your blood. The authors of a small 2018 study found that taking magnesium supplements may help regulate your blood sugar levels by managing insulin action.
Muscle Cramp Relief: Magnesium deficiency may cause painful muscle cramps. As a result, some magnesium supplements are marketed to prevent or improve muscle cramping. For example, a 2002 study found that participants who received 300 mg of magnesium daily for 6 weeks reported fewer muscle cramps compared with those who received a placebo.
Improved Mood: Magnesium deficiency has been linked to depression. In fact, taking a magnesium supplement may improve depressive symptoms in some people.
Enhanced Athletic Performance: Various studies on the effects of magnesium supplements on exercise performance have found mixed results.
PMS Relief: Some research suggests that magnesium supplementation may help improve PMS symptoms. A 1998 study found that taking 200 mg of magnesium from magnesium oxide daily improved water retention associated with PMS. Another 2010 study found that supplementing with 250 mg of magnesium helped relieve PMS symptoms more effectively when combined with 40 mg of vitamin B6.
Migraine Reduction: People who experience migraines may be at risk of magnesium deficiency due to several factors, including genetic inability to absorb magnesium efficiently and increased excretion of magnesium due to stress. According to a 2017 review, supplementing with 600 mg of magnesium dicitrate (which contains 97.2 mg of elemental magnesium) could be a safe and effective option to reduce the frequency of migraine attacks. Another 2019 study found that taking 500 mg of magnesium oxide (300 mg of elemental magnesium) was as effective as a prescription drug at reducing the frequency and duration of migraine attacks over an 8-week period.

Potential Risks and Side Effects

While magnesium is generally safe, excessive intake can lead to side effects. It’s best to consume your daily magnesium intake throughout the day. If you consume too much all at once, you may experience symptoms of magnesium toxicity.

Common Side Effects

Diarrhea: Magnesium can have a laxative effect, especially at higher doses.
Nausea and Abdominal Cramps: Some individuals may experience digestive discomfort.
Magnesium Toxicity: Taking more magnesium than the recommended daily value may lead to magnesium toxicity.

Symptoms of Magnesium Toxicity

Although rare, magnesium toxicity can occur with very high doses of magnesium supplements. Symptoms may include:
