Globally, over 70% of fish can be used for collagen production from its by-products, such as the skin, scales, and bones, making it a sustainable alternative to mammalian collagen. Fish collagen is gaining popularity in supplements and cosmetics due to its high bioavailability and eco-conscious sourcing. This guide explores where fish collagen comes from, the types of fish used, and the benefits of using these often-discarded materials.

According to a 2016 study, extracts from chum salmon eggs induced the upregulation of collagen type I genes in human skin cell cultures, indicating that while fish eggs may not contain the protein directly, they can actively promote its synthesis. The question, “do fish eggs have collagen?” is more nuanced than a simple yes or no, involving a deeper look at its nutritional composition.

As a nutritious powerhouse, kelp is especially high in the mineral iodine, which is crucial for thyroid health. This sea vegetable also contains a wide array of other vitamins, minerals, and antioxidants, making it a valuable addition to many diets.

While seaweed is celebrated for its dense nutritional profile, including minerals and antioxidants, its role in detoxifying heavy metals is a subject of both scientific interest and significant caution. Certain compounds in seaweed can bind to heavy metals, but the plant itself can also accumulate toxins from polluted waters.

Collagen is the most abundant protein in the human body, but did you know it's found exclusively in animals, not plants or seaweed? While seaweed does not contain actual collagen, it is a powerhouse of nutrients that actively support and stimulate your body's natural collagen production.

Fish skin can contain a remarkably high concentration of collagen, with some studies showing up to 98% of total protein on a dry weight basis. Answering the question, "Which fish is highest in collagen?" requires looking beyond the fish fillet to the parts most rich in this fibrous protein.
