Skim milk is commonly used to support or treat calcium deficiency, and its use is justified by scientific evidence. Skim milk, like other forms of cow’s milk, is a rich natural source of calcium, which is essential for bone health and metabolic functions. Scientific literature and nutritional guidelines consistently cite dairy products—including skim milk—as an effective dietary means to help meet daily calcium requirements. According to the USDA and multiple clinical studies, an 8-ounce (240 mL) serving of skim milk provides approximately 300 mg of calcium, which is about 30% of the recommended daily intake for adults. Importantly, the removal of fat in the process of making skim milk does not significantly affect its calcium content.

Clinical reviews and population studies indicate that regular consumption of low-fat dairy products can contribute to optimal bone mineral density and may help reduce the risk of osteoporosis, particularly when combined with adequate vitamin D intake. Although there are debates about the relative contributions of dietary and supplemental calcium, the role of dairy as a reliable calcium source is well-established. Therefore, recommending skim milk for the dietary management of calcium deficiency is supported by substantial scientific validation and forms a part of evidence-based nutritional guidelines worldwide.
