Diet-by-Diet Breakdown
✓
Keto
Fully compatible. Zero carbohydrates, zero sugar, zero fat. Pure hydrolyzed protein. Will not affect ketosis. Marine collagen provides ~10g of protein per serving (2 scoops) without any carbohydrate load. Many keto dieters add it to bulletproof coffee, fat-based smoothies, or bone broth to increase protein intake without triggering an insulin response.
✓
Paleo
Fully compatible. Single ingredient — hydrolyzed collagen peptides from wild-caught fish. No grains, no legumes, no dairy, no refined sugar, no artificial ingredients, no processed additives. Wild-caught fish is a core Paleo food. The product has one item on the ingredient label: Hydrolyzed Marine Collagen Peptides (from Non-GMO, Wild-Caught Cod, Pollock, and Haddock).
✓
Pescatarian
Fully compatible. Derived entirely from fish — Cod, Haddock, and Pollock. Contains no bovine, porcine, or poultry ingredients. Marine collagen is the only collagen source suitable for pescatarians. Bovine and multi-collagen blends (which include chicken or eggshell membrane) are not pescatarian-compatible.
✓
Gluten-Free
Confirmed gluten-free. No wheat, barley, rye, oat, or grain-derived ingredients. Single-ingredient product with no fillers or binders that could introduce gluten cross-contamination.
✓
Dairy-Free & Soy-Free
No milk, casein, whey, lactose, or soy-derived ingredients. Safe for people with dairy or soy allergies or intolerances.
✗
Vegan / Vegetarian
Not compatible. Marine collagen is an animal-derived protein sourced from fish. It is not suitable for vegans or vegetarians.
A Note on "Vegan Collagen"
There are no true vegan collagen supplements. Products marketed as "vegan collagen" or "plant-based collagen boosters" contain precursor nutrients — Vitamin C, zinc, copper, proline — that may support your body's own collagen production. They do not contain actual collagen protein. If you follow a vegan diet and want to support collagen synthesis, a supplement combining Vitamin C, zinc, and copper is the closest available option — but it is not a direct substitute for collagen peptides.
Why Single-Ingredient Matters for Diet Compliance
Many collagen supplements contain added ingredients that can disqualify them from strict dietary protocols — artificial sweeteners (not Paleo), maltodextrin or dextrose (not Keto), whey protein fillers (not Dairy-Free), or multi-source blends that include chicken or bovine (not Pescatarian).
Zen Principle Marine Collagen Powder has one ingredient: Hydrolyzed Marine Collagen Peptides from Wild-Caught Cod, Pollock, and Haddock. No flavoring, no sweeteners, no fillers, no binders, no flow agents. This makes it compatible with more dietary frameworks simultaneously than almost any other collagen supplement on the market.

Is marine collagen paleo friendly?

Is marine collagen gluten free?
Yes. No wheat, barley, rye, oat, or grain-derived ingredients. Also dairy-free and soy-free.
Can vegans take marine collagen?
No. Marine collagen is derived from fish. No true vegan collagen exists. Vegan "collagen boosters" contain precursor nutrients (Vitamin C, zinc, copper) but not actual collagen protein.
Will marine collagen break my fast?
Technically yes — marine collagen contains protein (calories). If you practice strict water-only fasting, taking collagen would break the fast. However, many intermittent fasting protocols allow protein supplements during the eating window. Some "dirty fasting" approaches allow collagen in coffee. Check your specific protocol.
