Low 25-hydroxyvitamin D

A slightly low level of 25-hydroxyvitamin D, or low vitamin D, is a manifestation of vitamin D deficiency in the body. A slight decrease in vitamin D can lead to rickets, and patients often experience skeletal muscle relaxation, accompanied by some non-specific mental or neurological symptoms. Moreover, a slightly low level of vitamin D can lead to hand and foot deformities and adult rickets, joint pain, muscle atrophy, insomnia, diarrhea and other symptoms, and rickets can have a serious impact on children's intelligence.

Vitamin D is a key indicator for determining the body's physical condition and a key criterion for measuring the body's calcium absorption. Nowadays, most people have little outdoor activities and lack of sunlight exposure, so the deficiency of hydroxyvitamin D is particularly serious. Vitamin D in the human body mainly exists in two forms: vitamin D2 and vitamin D3. Vitamin D2 is mainly produced in plants; vitamin D3 is mainly produced in animal tissues and can be produced by the body.

The two types of vitamin D have the same physiological effects. Vitamin D2 has a mild specificity and is more suitable for pregnant women, fetuses and infants to supplement vitamin D; while vitamin D3 has a strong specificity, which promotes calcium absorption much higher than vitamin D2. At the same time, it also causes its own strong side effects, one of which is the thickening of soft tissue.

During pregnancy, the fetus needs a lot of calcium for bone development, so if pregnant women test low in hydroxyvitamin D, it is often a reminder of possible calcium deficiency. Since hydroxyvitamin D is an endogenous vitamin D in the body, it can promote the absorption of calcium. After the hydroxyvitamin D level is slightly low, it is necessary to supplement vitamin D orally. At the same time, the time of sun exposure should be increased to promote the absorption of calcium. And it is recommended to carry out basic calcium and zinc supplements every day, and increase the intake of meat, eggs and milk.
