6 months of Vitamin D
|Initial||Loading dose1||Loading Dose 2||Maintenance dose |
for remainder of 6 months
|< 10 ng||50,000 IU weekly |
|25,000 IU weekly 4 weeks||25,000 every two weeks|
|10-20 ng||-||25,000 IU weekly 4 weeks||25,000 every two weeks|
|20-30 ng||-||25,000 every 2 weeks for 8 weeks||25,000 once every 4 weeks|
Note: some other groups have all loading dosing completed in 1 week, or even one day
Study did not test vitamin D levels at the end of the 6 months, but probably those getting > 30ng of Vitamin D would have had much more than a 3 cm reduction in waist size

Overview Loading of vitamin D contains the followingLoading dose:
If a person is or is suspected to be, very vitamin D deficient a loading dose is typically given
- Loading = restore = quick replacement by 1 or more doses
- Loading doses range in total size from 100,000 IU to 1,000,000 IU of Vitamin D3
- = 2.5 to 25 milligrams
- The size of the loading dose is a function of body weight - see below
- Unfortunately, some doctors persist in using Vitamin D2 instead of D3
- Loading may be done as quickly as a single day (Stoss), to as slowly as 3 months.
- It appears that spreading the loading dose over 4+ days is slightly better if speed is not essential
- Loading is typically oral, but can be Injection (I.M,) and Topical
- Loading dose is ~3X faster if done topically or swished inside of the mouth
- Skips the slow process of stomach and intestine, and might even skip liver and Kidney as well
- The loading dose persists in the body for 1 - 3 months
- The loading dose should be followed up with on-going maintenance dosing
- Unfortunately, many doctors fail to follow-up with the maintenance dosing.
- About 1 in 300 people have some form of a mild allergic reaction to vitamin D supplements, including loading doses
- it appears prudent to test with a small amount of vitamin D before giving a loading dose
- The causes of a mild allergic reaction appear to be: (in order of occurrence)
- 1) lack of magnesium - which can be easily added
- 2) allergy to capsule contents - oil, additives (powder does not appear to cause any reaction)
- 3) allergy to the tiny amount of D3 itself (allergy to wool) ( alternate: D3 made from plants )
- 4) allergy of the gut to Vitamin D - alternative = topical

OBJECTIVES: To evaluate i) the correlation between vitamin D (vit. D) serum concentrations and metabolic syndrome (MetS); ii) the efficacy of 6 months supplementation therapy with vit. D.
METHOD: 200 patients were enrolled. Blood analyses and anthropometric measurements were carried out. Patients with hypovitaminosis D received an oral supplement therapy.
81% of the sample shows vit. D levels < 30 ng/mL. Rate of MetS was significantly higher in vit. D deficiency group than in vit D insufficiency (p = 0.009) and sufficiency (p = 0.002) groups. Vit. D shows a significant negative correlation with both waist circumference (WC) (ρ - 0.202 p = 0.004) and glycaemia values (FBG) (ρ -0.185 p = 0.009). After the supplementation therapy in a group of 60 subjects a significant increase in vit. D levels (p = 0.001) and a significant reduction in WC values (p = 0.001) were observed.
MetS, WC and FBG appeared to be associated vit. D status and it is well-known that central obesity, with the inflammatory alterations thereto correlated that determine insulin resistance, can be considered the "primum movens" for the development of MetS.
