Collagen
Best-in-class: Collagen Plus
Hydrolyzed collagen peptides that supply the amino-acid building blocks (glycine, proline, hydroxyproline) for skin, joint and connective tissue, often paired with vitamin C.
How Collagen actually works
Hydrolysed collagen peptides are absorbed as di- and tripeptides — prolyl-hydroxyproline in particular survives intact and appears in blood after ingestion. Two things follow: it raises circulating glycine, proline and hydroxyproline as substrate, and those specific peptides appear to signal fibroblasts directly, acting as a chemotactic and proliferative stimulus rather than merely supplying amino acids.
Collagen quick facts
| Suggested dose | 10–15 g daily; take with vitamin C, ~30–60 min before training for tendon goals. |
| How often | daily |
| Who it's for | Skin, hair/nail, joint and connective-tissue support; recovering athletes. |
✅ Clinically validated
- Meta-analyses show improved skin elasticity and hydration with daily peptides.
- RCTs report reduced activity-related joint pain and support for tendon/ligament recovery when dosed pre-exercise with vitamin C.
📊 Correlative data
- Collagen synthesis declines with age, tracking with skin and joint changes.
🧪 Theoretical / extrapolated benefits
- Specific bioactive di/tripeptides are proposed to signal fibroblasts to build collagen — supported but still being characterized.
These tiers tell you how much human evidence exists — not how well something works. This is the research space, and most of what’s in here is new rather than disproven. Something sitting at “theoretical” usually means nobody has funded the trial, not that the trial was run and failed.
The trap runs the other way too: something can be clinically validated and still do very little for you specifically. A statistically significant result in a study population is not a promise about your body.
- ✅ Clinically validated — human randomised trials or meta-analyses support it. The strongest footing available.
- 📊 Correlative — observational or epidemiological data. Suggestive, and genuinely useful for direction, but it cannot establish cause.
- 🧪 Theoretical / mechanistic — the mechanism is understood and often demonstrated in cells or animals, and the human trial doesn’t exist yet. Unproven is not the same as ineffective. Plenty of what’s standard practice today sat here five years ago.
✗ is a safety flag, not a grade. Where you see it, the concern is harm — not a disappointing trial. A compound tested for one purpose and found not to help there can still be worth studying somewhere else, so a negative result never gets rendered as a cross. It sits alongside the tier, because something can be both well-studied and genuinely risky.
My job is to tell you which one you’re looking at, and let you make the call. Grading something low isn’t me dismissing it — it’s me refusing to oversell it. This is the research space, and being able to reason forward from a mechanism matters as much as waiting for the trial.
The signalling mechanism is what makes collagen different from eating any protein, and it is better supported than the sceptical position allows. Meta-analyses show improved skin elasticity and hydration, and separately joint pain and bone density in postmenopausal women. It needs eight to twelve weeks. Vitamin C is required for the synthesis it stimulates, which is why they are usually combined.
Collagen — safety & side effects
- Well tolerated. Fullness, mild GI upset and an unpleasant aftertaste are the usual complaints.
- Source allergens matter — marine collagen is fish, bovine is beef, and both have caused reactions in sensitised people.
- Contains no tryptophan, so it is not a complete protein — it should not replace other protein. Caution with kidney disease (protein load) and in PKU, since it is high in phenylalanine-adjacent aminos.
- Heavy metal testing matters; collagen concentrates what the animal was exposed to.
