If you’ve been comparing collagen supplements, you may have noticed a number followed by “Da” or “Dalton” on the label – for example “~1,000 Da” or “~5,000 Da”. But what does this actually mean, and does it matter when choosing a collagen supplement?
What is a Dalton?
A Dalton (Da) is a unit of molecular weight used in chemistry and biochemistry. In the context of collagen supplements, it describes the average molecular weight of the collagen peptide fragments in the product. The lower the Dalton value, the smaller the peptide fragments.
For reference:
- Intact collagen molecule: ~300,000 Da
- Standard collagen hydrolysate: ~2,000–5,000 Da
- Low-molecular collagen peptides: ~1,000–2,000 Da
- Collagen tripeptides: ~300 Da
How is Collagen Hydrolysed to Different Dalton Values?
During hydrolysis, enzymes break the long collagen protein chains into shorter fragments. By controlling the type of enzyme, temperature, pH and processing time, manufacturers can produce peptides of different average molecular weights. More extensive hydrolysis results in smaller peptides (lower Dalton value).

Does a Lower Dalton Value Mean a Better Product?
Not necessarily – but it does mean a more soluble product. Smaller peptides dissolve more easily, especially in cold liquids, and may be absorbed more readily in the digestive tract. However, collagen hydrolysate at any molecular weight between ~1,000 and ~5,000 Da is already highly processed compared to intact collagen.
The most important quality criteria remain:
- Purity of the raw material
- GMP-certified production
- Independent lab testing
- No unnecessary additives
A low Dalton value is a quality indicator – but it is not the only one.
What Dalton Value Does CollMeCell Use?
CollMeCell offers collagen hydrolysate with ~1,000 Da and ~1,500 Da peptide sizes – produced in Germany under GMP-certified conditions and independently lab-tested for purity and quality.
Summary
- Dalton (Da) = molecular weight of collagen peptides
- Lower Da = smaller peptides = better cold-water solubility
- ~1,000 Da is considered low-molecular and highly soluble
- Dalton value is one quality indicator among several – not the only one
- Always check: source, production standard, lab testing and ingredient list
