ok couple more questions:
- how much b12, what time of day?
- how much d3, what time of day?
- is the cal/mag/zinc at the same time as the d3?
- does he get any other supplemental magnesium at a different time than the d3 intake?
the reason for the timing and dosage questions is that i'm suspicious that his d3 intake could be affecting his magnesium status. just looking at the way you present the list, it looks like a possibility. it did happen to me - then i chanced upon a pharmacist who recommended magnesium, and it worked wonders.
so depending on what he's doing for dosage and timing right now, there might be some additional steps you could take.
a few snippets:
"magnesium affects blood pressure by modulating vascular tone and reactivity."
"It has been reported that the concentration of extracellular magnesium ions ([Mg++]o) can affect blood flow, blood pressure and vascular reactivity in intact mammals."
"A small pilot study suggests that magnesium may prevent or delay progression of vascular calcification"
"Magnesium sulfate for control of muscle rigidity and spasms and avoidance of mechanical ventilation in pediatric tetanus."
"The effects of magnesium glycerophosphate oral therapy on spasticity was studied in a 35-year-old woman with severe spastic paraplegia resulting from multiple sclerosis (MS). We found a significant improvement in the spasticity after only 1 week from the onset of the treatment"
and a quick FYI copy of an earlier post to a sleep issues topic..
