- 1

Adjust the method
Your body makes collagen from amino acids and vitamin C — you can't absorb it intact from a scoop anyway.

Taste and correct
Plant swaps are usually a little less salty and less rich than collagen supplement. Season at the end and add acid (lemon, vinegar) or umami (miso, nutritional yeast) if the dish tastes flat.
Mistakes to avoid
- Swapping by volume when the recipe measures collagen supplement by weight — check the ratio above first.
- Using a sweetened or flavoured version in a savoury recipe.
- Ignoring the method change: Your body makes collagen from amino acids and vitamin C — you can't absorb it intact from a scoop anyway.
- Assuming every packaged product labelled "plant-based" is vegan — some still contain milk powder, honey or egg. Scan the barcode to be sure.
