Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Sericin has none that clears that bar.
Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.
No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.
Research strength. Research strength says how much work stands behind the combination. It is never a product score.
Independent record. Every finding is cited to a named trial, dated, and never written by the brand.
20 pairings are live across the library today. Checked 20 July 2026.
No study gave these as a pair, so they are not in the card above. But the reason they belong together is settled biochemistry, not a guess, so it is worth knowing.
Roughly a third of sericin's amino acid residues are serine, with aspartic acid and glycine making up much of the rest. Digested sericin therefore delivers serine, which SHMT converts to glycine while transferring a one-carbon unit to folate. Glycine supplementation feeds the same interconversion from the other side. This is amino acid biochemistry, not a demonstrated clinical pairing.
Oral sericin is digested to peptides and free amino acids like any other protein. Because of its composition, the amino acid it supplies most is serine. Free L-serine supplies the same residue without the peptide step. Which of the two is preferable depends on whether the peptide fraction is wanted, and that has not been settled.
The work was done in rats and measured chromium exposure and downstream metabolic markers rather than clinical outcomes in people. Peptides can enhance trace mineral uptake by keeping the metal soluble in the intestinal lumen, which is a known mechanism for other peptide fractions. Whether this holds in humans has not been tested. Read it as mechanistic rather than clinical.
Peptide fractions that resist upper gut digestion become substrate for colonic bacteria. The human work reported shifts in microbiota composition alongside gastrointestinal tolerability data. A change in composition is a marker, not an outcome, and the direction of any benefit was not established. The pairing with a defined probiotic strain has not been tested at all.
Sericin's hydroxyl-rich serine residues bind water and leave a flexible film on drying. Hyaluronic acid holds water in the same layer through a different polymer chemistry. Combining them is standard practice in hydrogel and topical formulation for humectancy and film integrity. This is a formulation property and says nothing about oral use.
Collagen peptides supply glycine, proline and hydroxyproline; sericin supplies serine, aspartate and glycine. The amino acid profiles complement rather than duplicate each other. In topical and hydrogel work they also co-form films. The combination is a formulation choice, and no trial has tested the pair for any endpoint.
The reported antioxidant behaviour of sericin comes from cell-free and cell culture systems, where its hydroxyl-rich residues chelate transition metals and slow metal-catalysed oxidation. Glutathione works enzymatically inside cells, which is a different compartment and a different mechanism. Any additive effect is theoretical at this point. Do not read laboratory antioxidant activity as an effect in people.
