1-25 Dihydroxy Vitamin D2

Understanding 1-25 Dihydroxy Vitamin D2 in Your Lab Results

1-25 Dihydroxy Vitamin D2, also known as calcitriol, is an active form of Vitamin D found in plants and certain supplements. It plays a crucial role in maintaining bone health by regulating calcium and phosphorus levels in the blood. Understanding your 1-25 Dihydroxy Vitamin D2 levels can provide insights into your overall health, particularly in relation to bone density and immune function.

The Role of 1-25 Dihydroxy Vitamin D2

1-25 Dihydroxy Vitamin D2 is essential for the absorption of calcium and phosphorus from the gut, which are vital minerals for bone formation and maintenance. This biomarker is particularly important for individuals who rely on plant-based sources of Vitamin D, as it is derived from ergocalciferol (Vitamin D2), which is found in fungi and fortified foods. Unlike Vitamin D3, which is synthesized in the skin through sunlight exposure, Vitamin D2 is often consumed through diet or supplements.

Factors Influencing 1-25 Dihydroxy Vitamin D2 Levels

Several lifestyle and nutritional factors can influence your 1-25 Dihydroxy Vitamin D2 levels. A diet rich in fortified foods, such as plant-based milks and cereals, can help maintain adequate levels. Additionally, taking Vitamin D2 supplements can be beneficial, especially for those with limited sun exposure or dietary restrictions. However, excessive intake of Vitamin D2 supplements can lead to elevated levels, which may cause adverse effects.

Health Implications of Abnormal Levels

Abnormal levels of 1-25 Dihydroxy Vitamin D2 can be indicative of various health conditions. Low levels may suggest a deficiency in Vitamin D, which can lead to weakened bones, increased risk of fractures, and conditions like rickets in children or osteomalacia in adults. Conversely, high levels might indicate hypercalcemia, a condition characterized by excessive calcium in the blood, which can result in kidney stones and cardiovascular issues.

Normal Ranges for 1-25 Dihydroxy Vitamin D2

The normal range for 1-25 Dihydroxy Vitamin D2 in the blood is typically between 20 to 60 picograms per milliliter (pg/mL). However, these values can vary slightly depending on the laboratory and the specific testing methods used. It is important to interpret your results in the context of your overall health and any symptoms you may be experiencing. Regular monitoring and consultation with healthcare professionals can help ensure that your Vitamin D levels remain within a healthy range.
