What Does Dalton Size Mean in Collagen Powder?

 

When researching collagen supplements, you may have come across terms like "Dalton size" or "kilodaltons (kDa)." But what does this actually mean, and why should it matter when choosing the right collagen powder?

Let’s unpack this important concept.

 

What Is Dalton Size?

Dalton (Da) is a unit used to measure molecular mass. When it comes to hydrolysed collagen, we’re usually talking in kilodaltons (kDa), 1 kilodalton equals 1,000 Daltons.

Collagen in its natural form is a large, complex protein. During hydrolysis, this protein is broken down into smaller collagen peptides, which are easier for the body to absorb. The smaller the peptide, the lower its Dalton size, and typically, the higher its bioavailability.

Molecular weights (in Daltons/kilodaltons) for hydrolysed collagen are typically distributed across a range, and it's common to describe the average molecular weight or to report what percentage of peptides fall within certain size ranges. 

 

Why Dalton Size Matters for Collagen Absorption

The body absorbs smaller peptides more efficiently. That’s why low molecular weight collagen peptides are often seen as more effective.

The optimal molecular weight range for bioavailability is between 2 kDa to 10 kDa (2,000–10,000 Da). This range is considered ideal for maximum absorption and effectiveness in supporting:

- Collagen synthesis

- Skin elasticity and hydration

- Joint and bone health

- Muscle recovery

- Gut lining repair

- Reducing inflammation

 

Dalton Size in Nutraviva Collagen Powders

At Nutraviva, we pride ourselves on transparency and quality. Here’s how our collagen powders compare:

-        Nutraviva Collagen Hydrolysate (Brazilian sourced) - Typical molecular weight: 3-5kDa.

-        Nutraviva Australian Collagen Hydrolysate - Typical molecular weight: 2.5–10 kDa

-        Nutraviva Marine Collagen - Typical molecular weight: 3-5kDa.

 

Dalton size is more than just a technical detail; it’s a key indicator of how well your body can use a collagen supplement.

With Nutraviva’s hydrolysed collagen powders, you’re choosing science-backed, easily absorbed collagen peptides to support your health and wellbeing from the inside out.
