If you’ve ever browsed collagen supplements, you’ve probably noticed some of them brag about being “low molecular weight.” It sounds technical—but what does it actually mean? In simple terms, it’s all about how small the collagen particles are after the protein has been broken down through a process called hydrolysis. Smaller particles (measured in Daltons) are easier for your body to absorb, which means you can actually get more out of your supplement.
Why Smaller Collagen Particles Matter
Your body can’t just take in big, intact collagen proteins—they’re too large to pass through your digestive system and into your bloodstream. That’s why collagen is broken down into tiny pieces called peptides. When these peptides are low molecular weight—usually between 1,000 and 3,000 Daltons—they can slip through your intestinal wall more easily, enter your bloodstream faster, and get to work in your skin, joints, bones, and other connective tissues where collagen is needed most.
Why Fish Collagen Has the Edge
One of the reasons marine collagen, like Ballstad’s premium fish collagen, gets so much love is because it naturally has a lower molecular weight compared to bovine or porcine collagen. This means your body can absorb it more efficiently, so you’re not just taking collagen—you’re actually using it. Whether your goal is to boost skin hydration, support joint comfort, or maintain strong bones, fish collagen offers a gentle yet powerful way to get results.
Choosing the Right Low Molecular Weight Collagen
If you’re shopping for collagen, look for a brand that’s transparent about both the source and the molecular weight. The best options are sustainably sourced, thoroughly tested for purity, and free from unnecessary fillers. Low molecular weight fish collagen is especially worth considering if you want the most bioavailable form, so every scoop or capsule is actually working for you.
