Vital ProteinsCollagen Peptides Advanced
Unflavored, collagen peptides
Incomplete protein. Most of the protein here is collagen, which lacks tryptophan, one of the nine essential amino acids. High concentration doesn’t make it a complete protein the way whey, egg or soy is.
Bench Facts
18 g of protein is 72 calories, more than the 70 on the label, because labels round. Protein per calorie is capped at 100%. Rated 4.5 out of 5 by 215,338 Amazon customers; blended with 100 average ratings, that’s a taste score of 4.50.

Research notes
Collagen is an incomplete protein: it lacks tryptophan (the label itself says collagen peptides are an incomplete protein), so its protein concentration and cost per gram overstate its value as a complete protein source. This is the flagship 20 oz unflavored Amazon listing, which is the Advanced formula (20 g bovine collagen peptides plus hyaluronic acid and vitamin C); Vital Proteins also sells a single-ingredient Collagen Peptides with the same 70 kcal / 18 g protein per serving. The Supplement Facts panel does not declare fat, carbohydrate or sugars (omitted because they are zero), recorded here as 0. Label says 'about 27 servings'; Amazon's variation is named '27 Servings' though its details table still says 28. Brand-site price for the 20 oz is $49.99. Because of label rounding, 18 g protein x 4 kcal = 72 kcal is more than the labeled 70 kcal, so protein concentration computes to about 103%.
