Marine collagen is a protein that is derived from fish. It is typically found in the skin, scales, and bones of fish. Marine collagen has been shown to have a number of benefits for the skin, including reducing the appearance of wrinkles and improving skin elasticity.
One of the main concerns with marine collagen is the potential for it to be contaminated with mercury. Mercury is a toxic metal that can cause a number of health problems, including neurological damage.
However, it is important to note that marine collagen itself does not contain mercury. The mercury contamination occurs when the fish that are used to produce collagen are themselves contaminated with mercury.
There are a number of ways to reduce the risk of mercury contamination in marine collagen. One is to choose fish that are known to be low in mercury, such as salmon and herring.
Another is to choose marine collagen that has been produced in a facility that uses strict quality control measures to ensure that the fish used are free of mercury contamination.
In general, marine collagen is safe to use and can provide a number of benefits for the skin. However, it is important to be aware of the potential for mercury contamination and to take steps to reduce the risk.
