withinUs TruMarine Collagen, 5000mg Hydrolyzed Marine Collagen from Wild-Caught Fish Scales, Unflavoured, Jar Box or Stick Pouch

withinUs TruMarine Collagen Details

One ingredient. 5000mg of hydrolyzed marine collagen per 5g serving, exclusively from the scales of wild-caught fish. Unflavoured. Available as a 56-serving jar, a box of 20 sticks, or a pouch of 50 sticks.

The sourcing is the part worth understanding. Most collagen on the market comes from bovine hide or porcine skin. withinUs uses fish scales exclusively — not skin, not bones. Scale collagen is predominantly Type I, the type that dominates skin, bone and connective tissue, and its peptides are smaller than bovine collagen's, which is the usual argument for better absorption.

Unflavoured is the point of this one. There is no sweetener, no flavour, no gum and no colour, so the scoop is entirely what you are paying for and it dissolves into coffee, tea, soup or a smoothie without changing the taste. Most flavoured collagens carry additives that make up a meaningful share of the tub.

The label calls out 195mg of lysine per serving, and the licensed claim runs through it: lysine is an essential amino acid the body cannot make, and it is directly involved in collagen formation. That is the mechanism the claim rests on rather than the collagen peptides being reassembled wholesale, which is not how digestion works.

The three formats cost differently per serving. The 56-serving jar works out lowest; the sticks cost more but travel, portion themselves and do not need a scoop. The 50-stick pouch sits between the two.

withinUs is a Canadian company built around TruMarine collagen, sourced exclusively from the scales of wild-caught fish rather than from hides or bones.

Who withinUs TruMarine Collagen Is For

This suits anyone who wants collagen without additives, and particularly people adding it to coffee or cooking where a flavoured product would clash. It is the straightforward pick if you have found flavoured collagens too sweet. The sticks are worth the premium if portability is what keeps you consistent.

It contains fish — unsuitable for a fish allergy, and not vegan or vegetarian. Consult a practitioner before use if you are pregnant or breastfeeding, have liver or kidney disease, or have been instructed to follow a low protein diet. Mild gastrointestinal upset is a known reaction. Collagen is a protein supplement, not a complete protein source — it is low in tryptophan and should not be treated as a protein powder.
