Can bone broth replenish collagen and calcium in the body?

Whether bone broth actually helps replenish collagen and calcium is a question that, according to a Vietnamese government medium, is being investigated. The source discusses the theory that the long cooking time of bones releases substances such as collagen and minerals such as calcium. These could then be absorbed by the body.
Collagen is a protein that naturally occurs in skin, hair and nails, while calcium is important for bones and teeth. According to the source, it remains unclear whether consuming bone broth actually leads to a measurable increase in these substances in the body. Scientific research into its effectiveness is lacking or limited.
The source emphasizes that bone broth is traditionally seen as nutritious, but it is uncertain to what extent it contributes to specific health benefits. Those considering using it as a supplement should, according to the article, first consider other proven sources of collagen and calcium, such as fish, dairy or nuts.
