Mag Cal Vanilla Liquid supports musculoskeletal health with a concentrated combination of organic magnesium and calcium citrate minerals, plus vitamin D. Magnesium supplementation supports active lifestyles by aiding in the maintenance of muscle function and promoting healthy bone mineral composition.^1,2  Vitamin D levels tend to be lower in overweight adults,³ and clinical trial results indicate that higher levels of vitamin D supplementation are needed to maintain normal vitamin D status in overweight individuals.⁴ In a year-long, double-blind, placebo-controlled clinical trial, 1000 IU daily of vitamin D significantly attenuated hip bone mineral loss in women aged 60-70 with mean BMI values > 25. After 1 year of supplementation, mean hip bone mineral density loss was approximately 0.05% in the vitamin D treatment group, in comparison with an approximate loss of 0.60% in the placebo group. Serum calcium levels were also significantly increased in the vitamin D group.
