Your digestive system is superb at one job: breaking proteins and peptides into pieces. That's great for dinner and a real headache for drug makers. Most peptide medicines swallowed as a tablet would be dismantled by stomach acid and enzymes long before reaching the blood, and any survivors struggle to cross the gut wall. That's why insulin, a peptide hormone, has been injected since 1922. Making peptides work by mouth is one of the field's biggest challenges.

Hydrolysis literally means splitting with water. In manufacturing, enzymes are used to cut long collagen proteins into much shorter peptides. You'll see it on labels as 'hydrolysed collagen' or 'collagen peptides', and they mean essentially the same thing. Most human studies of collagen supplements used this form. It dissolves readily in drinks, but 'hydrolysed' describes processing, not proof that a particular product does anything.

Collagen is the most abundant protein in the body, and scientists have identified 28 distinct types. Some form strong fibres, like the type I in skin and bone. Others build delicate meshes, such as type IV in the thin membranes that support layers of cells, or help anchor tissues together. All share a structure of three chains wound into a helix. Supplements focus on just a few of these types, a useful reminder that there is far more to collagen than a tub of powder.

Many peptide hormones start life as something bigger. The cell builds a longer precursor, called a prohormone, and then enzymes cut it at precise points to release the active hormone. Insulin is a good example. It is made as proinsulin, a single chain that folds up, and then a middle section is snipped out. That section, called C-peptide, is released into the blood alongside insulin, which is why doctors can measure it to estimate how much insulin someone's own pancreas is making.

'Clinically proven', 'doctor formulated', 'pharmaceutical grade'. These phrases sound official, but none of them is a licence. In the UK, a medicine is licensed only after the Medicines and Healthcare products Regulatory Agency (MHRA) has assessed its quality, safety and effectiveness. Supplements are regulated as foods, so they aren't assessed that way at all. A phrase on the box may point to one small study, or to nothing. Ask what study, in whom, and published where.

Jelly, panna cotta, the wobble on cold gravy: that's gelatin. When collagen-rich tissue is heated in water, the tightly wound collagen strands loosen and come apart. As the liquid cools, they tangle loosely together again and trap water, forming a gel. Hydrolysed collagen goes a step further, with enzymes cutting the protein into short peptides that dissolve easily and no longer set. Same origin, different processing.

Collagen is a family, not a single protein. Type I is the most common and gives strength to skin, bone, tendons and ligaments. Type II is the main collagen of cartilage. Type III often sits alongside type I in skin, blood vessels and internal organs. Supplements list types according to their source: hides and fish skin give mainly type I, cartilage gives type II. Once digested into peptides, the type matters less than labels suggest, with undenatured type II the notable exception.

Your nervous system does not only talk in fast chemical messengers like dopamine and serotonin. It also uses peptides. Neuropeptides are released by nerve cells to influence their neighbours, and they tend to act more slowly and for longer, adjusting the 'volume' of circuits rather than simply flicking them on or off. Researchers have identified a great many neuropeptides in the brain, involved in pain, appetite, sleep, stress and social behaviour.

'No pain, no gain' doesn't apply to medicines or supplements. Feeling flushed, sick, dizzy or unusually tired after taking something is not evidence that it's doing you good. It's evidence that your body is reacting, possibly badly. A product can cause side effects and still offer no benefit at all. If you notice something new after starting any product, mention it to a pharmacist or doctor. For prescribed medicines, get advice before stopping.

Hydroxyproline isn't added straight from food into your collagen. Your cells first build the collagen chain with ordinary proline, then enzymes modify some of it into hydroxyproline, which helps stabilise the triple helix. Those enzymes need vitamin C to function. Because hydroxyproline is so specific to collagen, researchers often measure it to estimate how much collagen is in a tissue or a food. Vitamin C contributes to normal collagen formation.
