Collagen Peptides: The Complete Guide

From triple helix to peptide — what the word actually means

The complete guide starts with the molecule: native collagen — the body's most abundant protein, built as rope-like triple helices that give skin, tendon, bone and cartilage their tensile structure: strong, insoluble, and in that form fairly useless as a supplement; hydrolysis — enzymatic chopping of those ropes into short fragments (di- and tripeptides prominent, hydroxyproline-proline pairs the signatures), producing a soluble powder that dissolves in anything and absorbs measurably into circulation: this is what 'collagen peptides' means, and it's interchangeable with 'hydrolysed collagen' on labels; why it matters — the human trial file (skin elasticity and hydration at 8-12 weeks, activity-related joint comfort over longer runs) was built almost entirely on hydrolysed material, so the word on the panel is the difference between buying the studied thing and buying gelatin's cousin (the terminology page, absorption in full).

Types and sources — the number game, deflated

The label's Roman numerals, translated honestly: Type 1 — skin, bone, tendon, ligament: the body's dominant collagen and the research's, present in marine and bovine peptides alike; Type 2 — cartilage's collagen, whose supplement form (undenatured Type 2, taken at tiny 40mg doses on an immune-tolerance mechanism) is a genuinely different product that shouldn't be confused with gram-scale peptides; Type 3 — Type 1's travelling companion in skin and vessels, along for the ride in bovine material; the deflation — multi-type blends sold as more-numbers-more-benefits are mostly labelling theatre: for the mainstream skin/joint file, hydrolysed Type 1 covers the territory, and source choice (marine's Type 1 skew versus bovine's 1+3 mix) matters less than hydrolysis, dose and testing (sources compared). Futuro Labs Marine Collagen plays it straight on every axis this guide has named: 1200mg hydrolysed Type 1 marine collagen per serving, 12mg vitamin C carrying the register's collagen-formation claim, 1.5mg zinc, £16.99 for 60 days (the review).

Using them properly — and the close

The practice section, kept honest: dose — the trial range is wide (capsule-tier ~1-3g through powder-tier 5-10g), with skin studies succeeding across it: pick a product whose per-serving number is stated and hold it constant (the dosage page); timing — genuinely free for general goals: with breakfast, in coffee, before bed — adherence beats clock-craft, with the single refinement being collagen-plus-vitamin-C before training for the connective-tissue crowd (that protocol); duration — 8-12 weeks before judgement, matching every positive trial and skin's own renewal cycle (the timeline); and expectations — no authorised claims exist for collagen itself, effects are modest and outcome-specific, and vegans should know 'vegan collagen' means precursor blends, not collagen (the myths page). The complete guide, closed in one sentence: hydrolysed Type 1 at a stated dose, taken daily for a quarter, judged by photos and diary — everything else on the label is typography.
