Most users notice changes in 8 weeks with daily use. Some report earlier improvements around week 4 such as softer fine lines and better skin texture. Keep going daily to maintain benefits.

Customers often report stronger hair and nails with consistent use. Some also mention reduced joint niggles. These tend to show from 6–10 weeks.

Short breaks of a few days are fine. If you stop entirely, results will gradually return to baseline over time.

Each sachet provides 8,000 mg of premium marine collagen peptides. This level is widely used in clinical protocols for visible skin outcomes while keeping calories low.

We use Peptan® hydrolysed marine collagen peptides – primarily type I with type III – produced under stringent quality controls. Peptan® is recognised globally for purity and consistent peptide profile.

• Trusted clinical pedigree – Peptan peptides are used in multiple peer-reviewed studies.
• Low molecular weight – hydrolysed to around ~2 kDa for efficient absorption.
• Tight sourcing controls – traceable fish origin with rigorous contaminant screening.

Hydrolysed peptides are absorbed in the small intestine, circulate in the bloodstream, then signal fibroblasts to support collagen formation in the dermis. Vitamin C contributes to normal collagen formation.

No. It is derived from fish, so it is not suitable for vegans or vegetarians.

We brought manufacturing in-house in the UK. That gives us end-to-end control of raw materials, hydrolysis compatibility, flavour balance and stability. We run tight in-process checks – pH, brix, organoleptic testing – and small-batch blend to avoid the “fishy” or “metallic” notes common in liquid collagens.

• In-house production reduces third-party margins and freight inefficiencies.
• Direct sourcing of Peptan® at scale.
• Lean operations – we prioritise quality control and pass efficiency savings to you. The result is Peptan®-grade performance with a pleasant flavour profile, at a fair price.
