Response to Daily Dosing

WSS =White South Sahara residents  BSS =Black South Sahara residents


Response to Monthly Dosing

WSS =White South Sahara residents  BSS =Black South Sahara residents


Note: Monthly groups started with a loading dose of 60,000 IU for 4 weeks

   There were no loading doses for the daily groups

Zinc increased ~2X with monthly Vitamin D


Copper increased 2X with monthly Vitamin D


The 25-hydroxyvitamin D3 (25OHD3) deficiency in chronic kidney disease (CKD) is associated with immune system dysfunction (pro-inflammatory cytokines storm) through macrophages renal infiltration, oxidative stress (OxS) damage and athero-thromboembolic risk. Conversely, cholecalciferol supplementation (25OHD-S) prevents kidney fibrosis by inhibition of vascular calcification and nephrotic apoptosis (nephrons reduction). The objective of this study was to investigate the pleiotropic effects of 25OHD-S on immunomodulation, antioxidant status and in protecting against thromboembolic events in deficiency CKD Black and White individuals living in the Southern Sahara (SS).
The oral 25OHD-S was evaluated in 60,000 IU/month/36 weeks versus in 2000 IU/day/24 weeks in Black (n = 156) and White (n = 150). Total serum vitamin D was determined by liquid chromatography-tandem mass spectrometry. All biomarkers of pro-inflammatory cytokines (PIC) were assessed by ELISA tests. OxS markers were assessed by Randox kits. Homocysteine and lipoproteine (a) were evaluated by biochemical methods as biomarkers of atherothromboembolic risk. All statistical analyses were performed with Student's t-test and one-way ANOVA. The Pearson test was used to calculate the correlation coefficient. The means will be significantly different at a level of p value < 0.05. Multiple logistic regressions were performed using Epi-info and Statview software. Vitamin D deficiency alters the PIC profile, OxS damage and atherothrombogenic biomarkers in both SS groups in the same manner; however, these disorders are more acute in Black compared to White SS individuals. The results showed that the serum 25OHD3 concentrations became normal (>75 nmol/L or >30 ng/mL) in the two groups.

We have shown that the dose and duration of 25OHD-S treatment are not similar in Black SS residents compared to White SS subjects, whilst the same inhabit the south Sahara environment.
It appears that a high dose intermittent over a long period (D60: 36 weeks) was more efficient in Black people; while a lower dose for a short time is sufficient (D2: 24 weeks) in their White counterparts.
The oral 25OHD-S attenuates PIC overproduction and OxS damage, but does not reduce athero-thromboembolic risk, particularly in Black SS residents.

Non-daily (Bolus) is better:

  1. Better compliance for everyone
    • Fewer opportunities to forget.
    • If happen to forget, just take the pill days or weeks later
    • Fewer times to have to take a pill - for those who dislike doing so
  2. Non-daily is better the ~20% who have a poor Vitamin D Receptor
    • A high concentration gradient is one of 14 ways to get past Vitamin D Receptor limitations
    • So, while 80% get no extra benefit from non-daily dosing, 20% will get an extra benefit

CKD RCT on this page found that both Zinc and Copper were increased only by monthly, not by daily dosing.
Suspect the monthly dosing got more vitamin D into cells by getting past gene limitations
