Peptide collagen powder is safe to take during pregnancy. However, when it comes to marine collagen, it is recommended to only use brands of marine collagen that have been tested for toxins and are deemed safe. This is important because marine collagen is sourced from fish and fish products can contain heavy metals. At Correxiko, we only source deep sea fish (cod, haddock, pollock) from pristine Canadian waters. All our batches are independently tested for heavy metals and other contaminants. We recommend to always check with your doctor or health care professional before taking any supplements when pregnant.
