Calcium is not only necessary for bone health but also participates in many important bodily functions such as nerve transmission, muscle contraction, blood clotting and regulating hormone activity. Therefore, calcium supplementation is necessary at all ages.
When mentioning calcium supplementation, many people often immediately think of milk. In fact, milk is an abundant source of calcium. A glass of milk of about 275 ml can provide nearly 34% of an adult's daily calcium needs. In terms of nutritional content, milk is one of the foods that effectively support calcium supplementation.
However, the amount of calcium the body absorbs does not completely depend on the content in milk. For calcium to be absorbed and used effectively, the body needs enough vitamin D to support absorption, vitamin C helps synthesize collagen and vitamin K supports calcium intake into bones.
In addition, not everyone can absorb nutrients from milk well. People with lactose intolerance or elderly people with reduced digestive function may experience bloating and diarrhea after drinking milk, thereby reducing the ability to absorb calcium and other nutrients. Therefore, milk is a good source of calcium, but the effectiveness of supplementation depends on the absorption capacity and nutritional status of each person.
