Product Information

In the United States, vitamin D can now be found in multi-vitamin/multi-mineral formulations as well as a single supplement in a range of dosage levels, including 1,000 to 5,000 IU of vitamin D 3 per dose and even up to 50,000 IU of vitamin D 2 per dose. Calcitriol, through its receptor, the VDR, suppresses parathyroid gene expression and parathyroid cell proliferation, providing important feedback loops that reinforce the direct action of increased serum calcium levels ( Slatopolsky et al. Thus, overall, calcitriol acts on the intestine, bone, and kidney as described above, and as illustrated in Figure 2-1 in Chapter 2, to elevate serum calcium levels, closing the calcium loop. Additional hydroxylation reactions, such as that mediated by CYP24A1, as shown in Figure 3-1, result in more polar metabolites with greatly reduced or no apparent biological activity.

Vitamin D with a strength of 1000-2000 international units daily is the recommended dose for most adults,” Dr.What remains of the original chylomicron after lipolysis is a chylomicron remnant, a cholesterol-enriched, triglyceride-depleted particle that still contains a fraction of its vitamin D content. The pharmacokinetic consequence of the sum of these catabolic systems, as shown in studies in rats, is a slightly reduced half-life for 1α,25(OH) 2D 2 compared with 1α,25(OH) 2D 3 ( Knutson et al.

This is a major global health issue, as childhood fractures can lead to life years of disability and/or poor quality of life. As described previously, the products of vitamin D metabolism are excreted through the bile into the feces, and very little is eliminated through the urine. Until very recently it was thought that each new urinary tract infection was caused by a new and distinct contamination.

In contrast, the role of vitamin D in cancer immunosurveillance of nascent or established cancers remains to be defined. Importantly, while a fraction of newly absorbed intestinal vitamin D is also transported along with amino acids and carbohydrates into the portal system to reach the liver directly, the main pathway of vitamin D uptake is incorporation into chylomicrons that reach the systemic circulation via the lymphatics. Experimental animal studies have indicated that vitamin D 2 is less toxic than vitamin D 3, but this has not been demonstrated in humans. Introducing ancillary amounts of D-mannose into the bladder coaxes the bacteria into attaching themselves to the more readily available D-mannose.
