Collagen Crash: 29 Plant-Based Foods That Actually Support Skin Elasticity

21. Shiitake Mushrooms — The Ergothioneine and Copper Synergist

Shiitake mushrooms are a standout, not just for flavor, but for their unique combination of two vital skin-supporting compounds: Copper and L-Ergothioneine. Copper is essential for the enzyme lysyl oxidase, which links collagen and elastin fibers, providing firmness. L-Ergothioneine is a powerful antioxidant that the body actively transports into skin cells, protecting them from damage. Sautéing shiitake mushrooms or incorporating them into broths delivers these critical minerals and antioxidants in a savory, highly bioavailable form, directly supporting the physical cross-linking and defense of your skin's structure.

22. Dried Thyme — The Concentrated Manganese and Flavonoid Source

This common kitchen herb packs an unexpected punch. Dried thyme is one of the most concentrated plant sources of the trace mineral Manganese. Manganese is a crucial cofactor for enzymes that build the glycosaminoglycans (GAGs)—the structural components in the skin that bind water and keep the tissue hydrated and plump. Furthermore, the flavonoids in thyme protect the vascular network that delivers nutrients to the skin. Adding thyme to your cooking, rubs, or sauces is an effortless way to ensure the underlying skin matrix has the necessary trace minerals to maintain its firmness and youthful bounce.
