What happens if I take collagen powder every day?

The clock of the hour and the clock of the week: what a daily scoop does to the blood and the gut, and what it costs the scales

What happens if I take collagen powder every day is a question that is usually given one answer, the trial window's, and needs four, because four different things happen on four different clocks and a reader who has heard only about the twelve-week result expects it in the first week, feels nothing, and either stops or begins imagining; the honest page runs the four clocks in order. The clock of the hour is the one nobody describes and everybody should know, because it is where the powder stops being collagen. A scoop of hydrolysed collagen stirred into coffee or water arrives in the stomach as a solution of peptides already cut short by the manufacturer's enzymes, and stomach acid and pepsin begin cutting them shorter; in the small intestine the pancreatic proteases and the enzymes on the gut wall finish the job, reducing the scoop to free amino acids and to di- and tripeptides, pairs and triples of amino acids that the gut wall absorbs directly through its own transporters. These are absorbed into the blood over the following hour or two, so that glycine, proline and hydroxyproline, the three amino acids that collagen is unusually rich in, rise above their fasting levels and peak at around one to two hours, along with small amounts of specific dipeptides such as prolyl-hydroxyproline that survive digestion and can be measured in plasma for a few hours; by the next meal, or within about four hours, they are back to baseline, taken up by tissues that use them, used for energy, or stripped of their nitrogen and the nitrogen excreted as urea. That is what happens every day on the clock of the hour, and it is exactly what happens after a bowl of bone broth, a piece of fish skin or a serving of any gelatinous cut of meat, since the gut does not know a scoop from a stockpot and the amino acids are identical. The clock of the week is the gut's. A daily 10g of protein arriving in a drink is a small change that some guts notice in the first days as fullness, a taste in water, a thicker texture in coffee, or looser stools, all recorded in the trial tables at the same rates as placebo and all settling within the first week or two as the gut adjusts, as it does to any new daily food; a reader who finds the scoop sits heavily can halve it or take it with a meal, and the gut's complaints are the only side effects the trials found at any dose, with the powder's own downsides, the drifting scoop, the clumping, the cost per gram, set out on the collagen powder downsides page. The scales are the other thing on the week's clock. A 10g scoop is about forty calories of protein, which is nothing in a day and something in a year: forty calories a day that displace forty calories elsewhere, because protein is filling and the reader eats a little less, cost nothing, while forty calories a day added on top of an unchanged diet are fourteen thousand six hundred calories a year, around a kilogram and a half of fat if nothing else changes, which is the honest arithmetic that the year at thirty grams on the too much every day page runs at triple the dose. Nothing else measurable has happened by the end of the first week, and a reader who feels that something has is feeling the week.

The clock of the trial window and the clock of never: what the instruments found, what never happens, and the worked example at capsule scale

The clock of the trial window is the one the shelf describes, and the honest page gives it with its numbers and its condition. At twelve weeks, the skin trials that gave 2.5 to 10g of collagen peptides a day measured elasticity and hydration on a marked patch of skin with a cutometer and a corneometer and found them a few percent higher in the collagen group than in the placebo group, a change that the instruments can detect and the eye usually cannot, with the wash-out data suggesting it begins to fade over the weeks after stopping. At twelve to twenty-four weeks, the joint trials that gave around 10g a day to people with knee pain found their pain and function questionnaire scores a point or two better than placebo, modest and real, with no change in cartilage on the scans that looked. At six months, the one nail trial found a millimetre or two more growth a month and fewer broken nails at 2.5g, and the one Achilles tendinopathy trial found more improvement with 2.5g beside calf strengthening than with placebo beside the same exercise. Those are the things that happen on the trial window's clock, and the condition attached to every one of them is that they are visible only against a baseline: a reader who photographed one patch of skin in fixed light, wrote down a pain score on one movement and marked one nail at the cuticle before the first scoop can look for them, and a reader who did not cannot see them and will either credit the powder with the season's drift or conclude it did nothing; the three baselines are on the is it working page. The clock of never is the list of things that do not happen, and it is the list a reader asking about every day most needs. Nothing accumulates: amino acids beyond the body's immediate use are not stored, so the body of a reader who has taken a scoop daily for a year contains no more collagen peptides than it did on the first morning, and the trials to twelve months found nothing building in blood tests or adverse events. No tolerance builds: a protein is substrate rather than signal, acts through no receptor and produces none of the adaptation that makes caffeine need a bigger cup, so the scoop in month twelve does what the scoop in month one did. No dependency forms: stopping produces no withdrawal, only the slow fading of the measured effect over weeks, as with any protein supply that stops. And the body's own collagen production is neither suppressed, since there is no feedback loop by which eaten collagen tells fibroblasts to stop, nor stimulated in any tissue a trial has looked at under a microscope, since collagen synthesis is driven by load, growth factors and hormones rather than by the arrival of its amino acids, the one exception being the synthesis marker that rose in blood after gelatin and vitamin C were taken before a loading session, which is a signal of the loading as much as of the gelatin. So a year of daily scoops, on all four clocks together, is a daily two-hour rise in three amino acids, a gut that adjusted in the first week, forty calories a day accounted for or not, a few percent and a point or two on the trial instruments if the reader had a baseline, no accumulation, no tolerance, no dependency, an effect that fades over weeks if the scoops stop, and a few hundred pounds spent at powder prices. The worked example is the capsule version of the same habit, stated on its true terms: two capsules, 1200mg hydrolysed type 1 marine collagen with 12mg vitamin C at 15% of its reference value plus zinc, 120 for £16.99 at 28p a day, lab tested and UK made, below the 2.5 to 10g doses at which the trial window's instruments moved, so that on the clock of the hour it does a smaller version of what the scoop does, on the clock of the week it costs five calories and no gut adjustment, on the clock of the trial window it offers vitamin C's collagen formation claim and a reason to measure, and on the clock of never it is identical. What happens if I take collagen powder every day: four things on four clocks, and the fourth clock is the reassuring one.
