In this article we will be discussing a very common question: vitamin d 3 range. It’s quite a sensitive & complex subject, as such we will do our best at providing a clear and concise article to clear any doubts you may have.
Reference Range
Many of the currently available assays measure and report on both vitamin D2 and D3 metabolites. 25-hydroxyvitamin D (25(OH)D) is the major circulating form of vitamin D; thus, the total serum 25(OH)D level is currently considered the best indicator of vitamin D supply to the body from cutaneous synthesis and nutritional intake. One exception is that 25(OH)D levels do not indicate clinical vitamin D status in patients with chronic renal failure or type 1 vitamin D-dependent rickets or when calcitriol (1,25-dihydroxyvitamin D) is used as a supplement.
Symptoms And Health Risks Of Vitamin D Deficiency
Yet, even without symptoms, too little vitamin D can pose health risks. Low blood levels of the vitamin have been associated with the following: Increased risk of death from cardiovascular disease
Cognitive impairment in older adults
Severe asthma in children
Cancer Research suggests that vitamin D could play a role in the prevention and treatment of a number of different conditions, including type1 and type 2 diabetes, hypertension, glucose intolerance, and multiple sclerosi.
How The Test Is Performed
The examples above are common measurements for results of these tests.
Normal value ranges may vary slightly among different laboratories. Some laboratories use different measurements or test different samples. 25 hydroxy vitamin D3 (cholecalciferol) is the vitamin D that your own body has made or that you absorbed from an animal source (such as fatty fish or liver) or a cholecalciferol supplement.
The two hormones (ergo- and cholecalciferol) work similarly in the body. The important value is the total 25 hydroxy vitamin D level in your blood. Many people are confused by the way these tests are reporte.
What Is Vitamin D?
Vitamin D is a fat-soluble vitamin that’s involved in many essential body functions. There are two forms of vitamin D in the diet and supplements: Vitamin D2 (ergocalciferol): found in some mushrooms. Vitamin D3 (cholecalciferol): found in oily fish, fish liver oil, and egg yolks.
D3 is the more powerful of the two types and raises vitamin D levels almost twice as much as D2 Significant amounts of vitamin D can also be made in your skin when exposed to UV rays from sunlight. Any excess vitamin D is stored in your body fat for later use.
