Introduction

25-hydroxyvitamin D affects fertility. Low levels of 25-hydroxyvitamin D may lead to decreased egg quality, impaired embryo implantation, and may contribute to the development of polycystic ovary syndrome. Deficiency in pregnant women may cause muscle cramps, intrauterine growth restriction, and delayed fetal bone calcification. Excess levels may result in calcium salt deposition, arthritis, and adverse effects on the digestive and nervous systems.

Generally, 25-hydroxyvitamin D can affect fertility and pregnancy preparation.

25-hydroxyvitamin D is a fat-soluble vitamin that primarily regulates calcium and phosphorus metabolism, promotes the absorption of calcium and phosphorus, strengthens bones, stimulates skin cell growth, and supports new bone formation and calcification. It also acts as an immune modulator. Low levels of 25-hydroxyvitamin D may lead to decreased egg quality, impaired embryo implantation, and may contribute to the development of polycystic ovary syndrome (PCOS). Additionally, 25-hydroxyvitamin D is crucial during pregnancy; deficiency in pregnant women may cause muscle cramps, intrauterine growth restriction, and delayed fetal skeletal calcification. Excessive 25-hydroxyvitamin D can result in calcium salt deposition, arthritis, and adverse effects on the digestive and nervous systems, and in severe cases, may lead to kidney damage.

It is essential to maintain 25-hydroxyvitamin D within the normal range. When levels are low, increased sun exposure can help boost vitamin D naturally. It is recommended to get about one hour of sunlight daily, although prolonged exposure may harm the skin. Consuming foods rich in vitamin D—such as eggs, fish, and animal organs—can also help. In more severe cases, supplementation under medical supervision with vitamin D drops or chewable vitamin D tablets may be advised. For individuals with excessive vitamin D levels, it is recommended to discontinue supplements, drink plenty of water, and consume more vegetables and fruits to aid recovery.

Is fasting required for a 25-hydroxyvitamin D test?

In general, fasting is not required for a 25-hydroxyvitamin D test. This test measures the level of vitamin D in the body and is performed through a blood draw. Food usually does not affect the accuracy of this test, which can clearly determine the concentration of 25-hydroxyvitamin D in the body and provide accurate diagnostic results.

What causes low 25-hydroxyvitamin D levels in adults?

Low levels of 25-hydroxyvitamin D in adults may be caused by insufficient dietary intake of vitamin D, inadequate sun exposure, or abnormal liver function. Some individuals may have reduced vitamin D intake due to an unbalanced diet or picky eating habits. Infrequent sun exposure leads to decreased cutaneous production of vitamin D, and impaired liver function can affect the conversion of vitamin D into 25-hydroxyvitamin D.

Difference between 25-hydroxyvitamin D and vitamin D

The differences between 25-hydroxyvitamin D and vitamin D are reflected in their distinct absorption mechanisms, bioavailability, and biological activity. 25-hydroxyvitamin D is primarily absorbed through the small intestine, whereas vitamin D needs to undergo a series of metabolic transformations in the liver to become 25-hydroxyvitamin D before it can be absorbed in the small intestine.

What does high 25-hydroxyvitamin D mean?

High levels of 25-hydroxyvitamin D result from excessive intake of vitamin D, leading to its accumulation in the body. Vitamin D is a fat-soluble vitamin, and 25-hydroxyvitamin D is formed when vitamin D undergoes hydroxylation in the liver. Elevated 25-hydroxyvitamin D levels may indicate excessive vitamin D supplementation, resulting in its buildup and causing vitamin D toxicity.
