Reinventing collagen with ultra-low molecular weight di & tripeptides: Unlocking new product formats
Collagen has moved firmly into the mainstream, spanning beauty supplements, sports nutrition, healthy ageing solutions and weight management products. Backed by growing scientific interest in its benefits for skin, bone and joint health, it has become a staple ingredient across categories.
But as demand grows, so do expectations. Today’s consumers are more informed and increasingly looking for simpler, more convenient ways to consume collagen. This is putting pressure on brands to deliver high-performance solutions in smaller, easier-to-use formats.
The importance of peptide content
Collagen peptides are made by hydrolyzing collagen into shorter chains of amino acids, making them easier to use in foods, beverages and supplements than native collagen. However, their size can vary considerably. Standard market collagen (2000Da-3000Da) is generally made up of longer-chain peptides.
This matters because molecular weight and content of small peptides can influence bioavailability: how much of an ingredient is fast absorbed and made available in the body. Dipeptides contain two amino acids, while tripeptides contain three. In addition to their small size, the presence of specialized intestinal peptide transporters facilitates their efficient absorption [1-4].
Why faster absorption matters
Recent human and cell model research confirms the relevance of collagen peptide bioavailability. Ultra–low molecular weight collagen rich in di & tripeptides showed enhanced absorption kinetics [1].
For formulators, faster absorption is more than a technical benefit. It can support clearer product positioning and help create more convenient formats.
Why lower dosage opens new possibilities
Traditional collagen products often require large serving sizes. This can make formulation more challenging, especially where space is limited. Higher doses may affect taste, texture, mouthfeel and solubility in formats such as mouth-dissolving powders, coffee capsules, gummies, soft capsules, tablets, shots and beverages.
Lower dosage can change what is possible. When collagen peptides can be delivered more efficiently, brands can move beyond conventional powders and create smaller, easier-to-use products. For consumers, this can mean daily collagen without large scoops or high-volume servings.
Market data also shows why these formats matter. According to NIQ, collagen is gaining traction beyond traditional supplements, with strong growth reported in snack and beverage applications [5].
A new approach to collagen peptides
SOLUGEL® Supra is PB Leiner’s ultra-low molecular weight fish collagen peptide solution. With a molecular weight of 500 Da, it is significantly smaller than standard market collagen peptides.
It also contains 45% di & tripeptides and offers excellent organoleptic properties, clarity and broad pH stability. PB Leiner data shows rapid uptake within minutes and 4x faster absorption versus standard collagen peptides [1].
This makes SOLUGEL® Supra suitable for concepts where speed, efficiency and format flexibility matter, from beauty-from-within and sports nutrition to smaller, lighter daily serving formats.
A smarter way to formulate collagen
Not all collagen peptides are created equal. Peptide content and size plays a critical role in how collagen is absorbed, how efficiently it can be delivered and how easily it can be formulated. With faster absorption, greater efficiency and lower dosage (1-5 g / day), SOLUGEL® Supra helps brands unlock the next generation of collagen applications.
