The effects of magnesium and vitamin E co‐supplementation on wound healing and metabolic status in patients with diabetic foot ulcer: A randomized, double‐blind, placebo‐controlled trial
Abstract
This study was carried out to determine the effects of magnesium and vitamin E co‐supplementation on wound healing and metabolic status in patients with diabetic foot ulcer (DFU). The current randomized, double‐blind, placebo‐controlled trial was conducted among 57 patients with grade 3 DFU. Participants were randomly divided into two groups to take either 250 mg magnesium oxide plus 400 IU vitamin E (n = 29) or placebo per day (n = 28) for 12 weeks. Compared with the placebo, taking magnesium plus vitamin E supplements reduced ulcer length (β [difference in the mean of outcomes measures between treatment groups] −0.56 cm; 95% CI, −0.92, −0.20; p = 0.003), width (β −0.35 cm; 95% CI, −0.64, −0.05; p = 0.02) and depth (β −0.18 cm; 95% CI, −0.33, −0.02; p = 0.02). In addition, co‐supplementation led to a significant reduction in fasting plasma glucose (β −13.41 mg/dL; 95% CI, −20.96, −5.86; p = 0.001), insulin (β −1.45 μIU/ml; 95% CI, −2.37, −0.52; p = 0.003), insulin resistance (β −0.60; 95% CI, −0.99, −0.20; p = 0.003) and HbA1c (β −0.32%; 95% CI, −0.48, −0.16; p < 0.003), and a significant elevation in insulin sensitivity (β 0.007; 95% CI, 0.003, 0.01; p < 0.001) compared with the placebo. Additionally, compared with the placebo, taking magnesium plus vitamin E supplements decreased triglycerides (β −10.08 mg/dL; 95% CI, −19.70, −0.46; p = 0.04), LDL‐cholesterol (β −5.88 mg/dL; 95% CI, −11.42, −0.34; p = 0.03), high sensitivity C‐reactive protein (hs‐CRP) (β −3.42 mg/L; 95%…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 57 participants or records.
