Frequently asked questions
- What is marine collagen?
- Collagen peptides sourced from fish (typically fish skin), rather than the bovine or porcine source of most collagen powders. Marine collagen is the standard pescatarian option.
- Where is it sold?
- Holland & Barrett at £20.61 is the listed retailer.
- Is the IGEN cert a banned-substance test?
- No — IGEN Non-GMO Tested verifies non-GMO sourcing only. Vital Proteins' Chocolate Collagen Peptides carries NSF Certified for Sport, which is the banned-substance cert in their line.
- Is marine collagen better than bovine?
- Different amino-acid profiles. Marine collagen has higher proline/glycine and is often marketed for skin support; bovine collagen has more Type I/III. Dietary restrictions and personal preference usually decide.
- Vegan-friendly?
- No — marine collagen is fish-derived. Vegan collagen 'builders' (typically amino-acid blends) exist as a separate category.
