Yes, Vital Proteins Collagen Peptides is a hydrolyzed collagen product. The terms “collagen peptides” and “hydrolyzed collagen” refer to the same thing: collagen protein that has been broken down through enzymatic hydrolysis into smaller chains of amino acids. Vital Proteins uses these terms interchangeably across its product line, and the single ingredient listed is collagen derived from grass-fed, pasture-raised bovine hide.
What “Hydrolyzed” Actually Means
Collagen in its natural state is a large, tough protein. It’s the main structural protein in skin, bones, tendons, and connective tissue. In that raw form, your body can’t absorb it efficiently. Hydrolysis is the process of using enzymes to break those large collagen molecules into much smaller fragments called peptides.
These smaller peptides dissolve more easily and pass through the gut wall into your bloodstream far more readily than intact collagen. A randomized controlled trial published in Nutrients found that enzymatically hydrolyzed collagen raised blood levels of the key collagen amino acids (glycine, proline, and hydroxyproline) within 20 minutes of ingestion, compared to 40 minutes for a less thoroughly hydrolyzed version. The hydrolyzed form also produced significantly higher peak concentrations of all three amino acids over a four-hour window. In practical terms, hydrolysis makes collagen more bioavailable, meaning more of what you swallow actually reaches your tissues.
Collagen Peptides vs. Gelatin
Gelatin is partially hydrolyzed collagen. It dissolves in hot water but gels when it cools, which is why it’s the base of Jell-O. Collagen peptides are hydrolyzed further, into even smaller fragments that won’t gel. This is why collagen peptide powders like Vital Proteins dissolve in both hot and cold liquids without thickening them.
There’s one nuance worth knowing about temperature. A food scientist at Texas A&M University has noted that collagen’s molecular structure breaks down at temperatures above body temperature, essentially converting it into gelatin. Collagen peptides have already undergone that breakdown, so they behave more like a standard protein powder. If you’re adding a peptide powder to hot coffee, the structure has already been reduced during manufacturing. Mixing into a cold beverage preserves the peptide form as-is.
Sourcing and Certification
Vital Proteins sources its flagship Collagen Peptides from grass-fed, pasture-raised bovine hide. The product contains a single ingredient with no additives or fillers. The company, now owned by Nestlé, holds NSF Certified for Sport certification under NSF Guideline 306, which screens for banned substances and contaminants. This certification is typically relevant for athletes subject to drug testing, but it also signals that the product has undergone independent quality checks beyond what the FDA requires for dietary supplements.
How Much Hydrolyzed Collagen Shows Results
Clinical research on hydrolyzed collagen peptides has used a wide range of doses. For skin health, studies have tested anywhere from 372 milligrams to 10 grams daily. The broader evidence suggests that 2.5 to 15 grams per day is both safe and effective for most purposes, including skin elasticity, joint comfort, and bone support. Vital Proteins recommends one to two scoops per serving, which falls within that clinical range.
The key amino acids your body gets from hydrolyzed collagen, particularly glycine, proline, and hydroxyproline, are the raw materials used to build and repair your own collagen. Your body doesn’t absorb collagen and slot it directly into your skin or joints. Instead, the peptides and amino acids serve as building blocks that your cells can use for collagen synthesis wherever it’s needed.
What to Look for in Any Collagen Product
If you see “collagen peptides” on a label, the product is hydrolyzed. If you see “hydrolyzed collagen,” same thing. The two phrases describe the same end result. “Collagen protein” without the word “hydrolyzed” or “peptides” could mean gelatin or a less processed form, so check the label carefully.
Third-party testing matters more with collagen than with many supplements, because collagen is derived from animal tissue that can concentrate heavy metals. NSF certification, USP verification, or similar independent testing provides a layer of assurance that the product contains what it claims and stays below safety thresholds for contaminants. Vital Proteins carries the NSF Certified for Sport mark, which covers both purity and label accuracy.
