Did you know?
Vitamin D Binding Protein (GC) gene can decrease the bio-available Vitamin D that can get to cells,- GC is not the only such gene - there are 3 others, all invisible to standard Vitamin D tests
- The bio-available calculation does not notice the effect of GC, CYP27B1, CYP24A1, and VDR
- The actual D getting to the cells is a function of measured D and all 4 genes
- There is >2X increase in 8+ health problems if have poor VDBP (GC)
- It appears that VDBP only blocks oral vitamin D,
- but NOT Vitamin D from sun, UV, topical or inhaled (tissue activated)
- A clue: - Vitamin D from UV is 2X better for MS than oral Vitamin D

Factors to take into account when interpreting 25-hydroxy-vitamin D serum levels
Acta Clin Belg. 2024 Mar 7:1-6. doi: 10.1080/17843286.2024.2327218 – PDF behind a $65 paywall
Joris R Delanghe 1, Marijn M Speeckaert 2 3, Thomas Maenhout 1Background: Assessing vitamin D status, typically evaluated using serum or plasma 25-hydroxy vitamin D [25(OH)D] concentration, is complex because of various influencing factors.
Methods: Seasonality significantly affects intra-individual variability in 25(OH)D levels. This variation can be addressed by employing cosinor functions that are tailored to the geographical location of the patient to correct for seasonal effects. In addition to seasonality, genetic factors, such as DBP polymorphism and body composition, particularly adiposity, play crucial roles. Dialysis patients with DBP 2-2 phenotype exhibit higher vitamin D requirements. Genotyping/phenotyping of DBP allows for better tailored vitamin D supplementation. The lipid-soluble nature of vitamin D also interacts with plasma components such as serum triglycerides, which can influence vitamin D measurements. Adiposity, which is negatively correlated with vitamin D concentration, necessitates body mass-based mathematical adjustments for accurate vitamin D assessment in subjects with extreme BMI values.
Conclusions: Accordingly, vitamin D replacement therapy must be personalized, taking into account factors such as body size and seasonal variations, to effectively reach the target serum 25(OH)D concentrations.
Introduction (from DeepDyve)
Owing to a markedly increased interest in the role of vitamin D in human health, the determination of 25- hydroxy vitamin D [25(OH)D] in serum or plasma has become a frequently requested laboratory test [1 ]. This rise in popularity can be attributed not only to the growing recognition of the wide-ranging health implications of vitamin D [2,3] but also to significant advancements in the effectiveness of vitamin D analysis techniques [3].The intraindividual biological variability (CVI) has been reported to be 4.7% for 25-hydroxy vitamin D. In contrast, interindividual variation (CVG), representing diverse homeostatic points among subjects within the same population, was significantly higher at 64.3% for 25(OH)D [4]. The calculated reference change value (RCV) for 25(OH)D was 18.0%. These data indicate that interindividual variation markedly surpasses intraindividual variation in 25(OH)D levels [4].
On top of the biological variation of 25(OH) vitamin D, in moderate and Arctic climates, vitamin D levels exhibit significant seasonal variability, primarily due to changes in sunlight exposure. This variability becomes more pronounced with increasing distance from the equator, with studies indicating a marked decrease in vitamin D synthesis in populations at higher latitudes. The biological mechanisms underlying this phenomenon, including the reduced capacity of the skin to synthesize vitamin D under lower UV conditions, warrant further discussion [5,6].
Vitamin D, a fat-soluble vitamin, relies on a specific transport protein, known as the vitamin D binding protein (DBP), for its circulation in the bloodstream. This binding protein plays a crucial role in the bioavail- abilitv and metabolic reoulation of vitamin D. nosino a complex challenge for interpreting the vitamin D status from serum or plasma 25(OH)D concentrations. The complexities of this relationship, particularly in different physiological and pathological states, emphasize the need for a more nuanced approach to vitamin D analysis [7].Most clinical laboratories tend to oversimplify the interpretation of vitamin D status by comparing test results with generic 'summer' and 'winter' reference values. These seasonal reference values, which are often inadequately defined, fail to offer a comprehensive correction for individual variability and geographical differences, leading to potential misinterpretations in vitamin D status assessment. The scientific basis for these reference values, as well as alternative methodologies that might provide more accurate assessments, are areas ripe for exploration [8-10].
