Effect of Quercetin Supplement on Some Bone Mineralization Biomarkers in Diabetic Type 2 Patients
Abstract
Background: Diabetes associated with multiple metabolic problems in the body, including bone mineralization remodeling, osteoporosis and increase risk of fracture. Quercetin is natural flavonoids and according to animal studies; it has potent antioxidant, antidiabetic and protective effect against bone loss due to various causes. Objectives: explore effect of quercetin as nutritional supplement administrated orally on some bone mineralization bio-markers such as calcium, vitamin D and osteocalcin in Iraqi diabetic patients. Methods: interventional double-blind placebo randomized controlled study in which 40 patients with type 2 diabetes mellitus (age range 40-45) assigned randomly (using simple randomization) in either control (n=20) or study (n=20) group. Study group received Quercetin oral supplement as 500mg capsule once daily for three months. Venous blood was used for measuring Serum calcium, 25(OH) vitamin D and osteocalcin at base line and after 3 months. Results: After 3 months treatment with Quercetin; levels of Osteocalcin (28.1±7.6), serum calcium (9.2±1.8) and 25(OH) vitamin D (26.6±8.7) were significantly (p<0.05) higher than pretreatment values of osteocalcin (24.0±8.6); serum calcium (7.0±2.2) and 25(OH) vitamin D (20.6±7.7) and control values of serum calcium (6.8±2.0) and 25(OH) vitamin D (20.8±7.4), but not Osteocalcin (25.2±9.0). There was also significant correlation between use of quercetin; elevation of serum calcium and osteocalcin (r= 0.454; p=…
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: 40 participants or records.
