The interactive effect of vitamin D3 supplementation and vitamin D receptor polymorphisms on weight and body composition in overweight women with hypovitaminosis D: a randomized, double-blind, placebo-controlled clinical trial.

Different responses to vitamin D supplementation may be due to genes involved in vitamin D metabolism, including the vitamin D receptor () gene. The present study aimed to determine the interactive effect of vitamin D supplementation and polymorphisms, including (rs2228570) and (1544410) on weight and body composition in overweight women with hypovitaminosis D. This study comprised two phases: a double-blind, randomized and a before-after clinical trial.

No association between infant growth and adherence to the dietary approaches to stop hypertension (DASH) diet in lactating women.

Objective: Breastmilk is considered an optimal food for infant development especially during the first 6 months of life. However, little evidence exists regarding maternal dietary intake and infant growth. We evaluated how adherence to the DASH diet in lactating women is associated with the infant weight, height and head circumference at birth, 2 and 4 months of age.

Melatonin Supplementation and Anthropometric Indices: A Randomized Double-Blind Controlled Clinical Trial.

Obesity, as the most common metabolic disorder in the world, is characterized by excess body fat. This study is aimed at determining the effects of melatonin supplementation on body weight, nody mass index (BMI), waist circumference (WC), and body fat mass percentage (BFMP) in people with overweight or obesity. Thirty eight overweight or class-I obese adult individuals were recruited in the study (8 men and 30 women).
