Not only are amino acids necessary for hormone production, but consuming marine collagen can also help to restore an amino acid equilibrium that favours healthy hormonal balance (1). Many of the meats commonly consumed in Western culture, including boneless, stockless muscle meats, are high in the amino acids tryptophan, cysteine, and methionine (2). If these amino acids aren't properly balanced with other amino acids, such as glycine and proline (abundant in marine collagen), they can lead to an increase of the stress hormone cortisol and suppress thyroid hormones. In women, high levels of cortisol can also interfere with the body's ability to produce progesterone, which is key to balancing estrogen in the body, while elevated cortisol levels in men can decrease testosterone production (3)(4).
Sourced from the by-products of wild-caught fish, our marine collagen is free of hormones and antibiotics—unlike conventionally raised meat and dairy—which can disrupt hormone health.
For these reasons, our marine collagen should be safe to consume if you are undergoing hormonal therapy or treatment, however we recommend that you speak to your primary healthcare practitioner before starting any new supplement first if you have any concerns.
