the research on zinc status in ms is more controversial, ie some studies find high zinc and some studies find low zinc in ms patients. this one requires individual assessment, ie, can you effectively absorb vit d3? is your uric acid low? if so, zinc could be the problem. in the second study below, note that the patients have poor zinc status with or without pressure sores. the presence of pressure sores is (to me anyway) a dead giveaway re especially poor zinc status.
Zinc and copper in multiple sclerosis.http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1083158/
The serum concentrations of zinc and copper were measured in 50 patients with multiple sclerosis. Lower serum zinc levels were found compared to age- and sex-matched controls.
In younger patients low serum copper concentrations were noted...
Iron and zinc status in multiple sclerosis patients with pressure sores.
Measurements of weighted dietary intakes and plasma determinations of albumin, iron, zinc, ascorbic acid and TIBC were carried out on twenty female multiple sclerosis patients in a long-stay hospital for disabled people. The group included ten patients with a recent history of pressure sores, closely matched with ten patients without pressure sores
... For both groups, intakes of
energy, folate, vitamin D, iron and zinc were less than recommended values.
Mean plasma levels of albumin and iron were towards the lower limit of the normal range, whilst that for zinc was considerably less than the normal range
. Plasma TIBC was slightly above the normal range. Levels of plasma iron and zinc were significantly lower in the pressure sore group. The data indicate that severely disabled hospitalized patients with multiple sclerosis may be at risk of poor nutritional status. The results suggest that in the presence of pressure sores, there are increased requirements for specific nutrients, notably zinc and iron. Consideration is given to the possible value of supplementation of these individuals.
