[헤럴드경제=육성연 기자] Calcium is not the only nutrient required for bone health. Calcium is a nutrient with a low absorption rate in the body, so in order to fulfill its role properly in our body, we need a ‘nutrient partner’ to help it. That is why the word ‘Kalmadi’ is popular recently.

‘Kalmadi’ is an abbreviation of calcium, magnesium and vitamin D, and refers to a combination of nutrients needed to maintain bone health.

▶ Magnesium

Magnesium is a mineral that is closely related to the body’s functioning of calcium. It transports calcium throughout the body and also prevents calcium from escaping from the bones.

Magnesium is consumed during the absorption of calcium in the body, so if you consume too much calcium alone, the body can become deficient in magnesium. In other words, if you take calcium supplements, you should also pay attention to your magnesium intake.

Studies also show that magnesium regulates the amount of vitamin D in the blood to an appropriate level. According to Professor Daichi’s team at Vanderbilt University Medical Center in the United States, taking magnesium supplements showed that people with vitamin D deficiency increased their vitamin D levels, while those with excess vitamin D decreased.

Magnesium is found in green leafy vegetables, legumes, whole grains, nuts and seed foods.

▶ Vitamin D

Vitamin D, along with calcium, plays an important role in bone health. According to medical experts, vitamin D helps the large intestine and kidneys absorb calcium, and builds calcium in the bones to increase bone density. Therefore, when vitamin D is severely deficient, bone density begins to decline and the risk of osteoporosis increases.

Vitamin D also plays a role in regulating the concentration of calcium and phosphorus in the body within the normal range. When the phosphorus concentration in our body increases, there is a risk of calcium absorption disorder due to changes in the parathyroid hormone. In other words. No matter how much calcium you eat, if you don’t have enough vitamin D, you won’t see the effect.

The Korean Nutrition Association suggests that the recommended daily intake of vitamin D for adults is 400 IU (international unit).
