- Intramuscular injection of 0.5 mg/kg progesterone twice daily
- 5µg/kg oral vitamin D3 twice daily up to 5 days
= 32,000 IU daily for 80 kg (176 lbs) person (400 IU/day/kg) = total of 160,000 IU
many other vitamin D studies use loading doses of 300,000 to 800,000 IU
Some of the study participants might have achieved a useful level of vitamin D by day 5
A single loading dose of Vitamin D would have resulted in good level in 3 rather than 5 days

It appears that Progesterone improves the Vitamin D Receptor

Overview Loading of vitamin D contains the followingLoading dose:
Vitamin D loading dose (stoss therapy) proven to improve health overview
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
Steroid hormones offer promising therapeutic perspectives during the acute phase of spinal cord injury (SCI) while the role of progesterone and vitamin D remain controversial. The aim of the current study was to investigate the effects of progesterone and vitamin D on functional outcome of patients with acute traumatic SCI.
This was a randomized clinical trial including 64 adult patients with acute traumatic SCI admitted within 8 hours of injury. All the patients received methylprednisolone on admission according to standard protocol (30 mg/kg as bolus dose and 15 mg/kg each 3 hours up to 24 hours). Patients were randomly assigned to receive intramuscular injection of 0.5 mg/kg progesterone twice daily and 5µg/kg oral vitamin D3 twice daily up to 5 days (n = 32) or placebo (n = 32). Patients were visited 6 days, 3 and 6 months after injury and motor and sensory function was assessed according to American Spinal Injury Association (ASIA) score.
There was no significant difference between two study groups regarding age (P = 0.341), sex (P = 0.802) and therapy lag (P = 0.609). The motor powers and sensory function increased significantly after 6 months in both study groups. Those who received progesterone and vitamin D had significantly higher motor powers and sensory function after 6 months of therapy.
Those who received the therapy within 4 hours of injury, had significantly higher motor powers and sensory function 6 months after treatment in progesterone and vitamin D group. Therapy lag was negatively associated with 6-month motor powers and sensory function in progesterone and vitamin D group.
Administration of progesterone and vitamin D in acute phase of traumatic SCI is associated with better functional recovery and outcome.
