Rather than relying on supplements, nutrition experts suggest that everyday foods can naturally support collagen production in the body. Collagen, a key protein responsible for skin elasticity and structure, declines with age due to factors like diet, stress, and environmental exposure. According to a recent report by MSN, vitamin C-rich foods such as citrus fruits and berries play a critical role in collagen synthesis. Protein sources like eggs, fish, and legumes provide essential amino acids, while bone broth offers collagen peptides. Omega-3 fatty acids from fish or flaxseeds help maintain skin hydration, and minerals like zinc and copper—found in seeds and nuts—support skin repair and regeneration.
