Bone broth lacks proven benefits for collagen levels in skin and joints

While bone broth has gained popularity as a natural source of collagen for skin and joint health, scientific evidence does not support its ability to directly rejuvenate tissues or improve bone density.

According to Antonio Zoido, a professor at the Universidad Europea de Andalucía, collagen consumed through food is broken down into amino acids during digestion. The body then uses these amino acids based on its specific needs, meaning consumption does not guarantee increased collagen production in specific areas like the skin or joints.

Experts note that there are currently no high-quality, controlled human clinical trials proving that bone broth consumption improves skin, bone density, or joint pain. Furthermore, the concentration of collagen-related amino acids in bone broth varies significantly depending on preparation and is typically lower than the doses used in successful supplementation studies. The mineral content, such as calcium and magnesium, is also considered limited per serving.
