What is the downside of taking collagen powder?

The first four lines of the audit: the scoop, the measure, the clumping and the taste

What is the downside of taking collagen powder is a question about a format more than a molecule, because collagen's own downsides, cost above whey, incomplete protein, fullness at large doses, the oxalate footnote and fish allergy with marine, are the same in every form, and what the powder adds is a set of downsides that belong to the tub, so the honest page audits the format on eight lines and scores the capsule and the gummy against it. Line one, the scoop. A tub's scoop holds around twenty grams, and twenty grams is a serving size chosen by the brand, not a dose chosen by a trial: the joint comfort trials gave around ten grams, the skin trials 2.5 to 10, the bone trial five, and only the tendon protocol reached fifteen, so a reader who follows the scoop takes double the joint dose and eight times the low skin dose without ever deciding to, pays for it, and sits heavily on it. Line two, the measure. A heaped scoop, a level scoop and a dessertspoon of the same powder differ from one another by roughly a factor of two, so a powder dose taken by eye drifts between ten and twenty-five grams from day to day, which matters to a reader trying to run the trials' dose for the trials' duration and is fixed only by a kitchen scale for the first week until the eye is calibrated. Line three, the clumping. Hydrolysed collagen is a fine, light powder that clumps when it hits cold liquid, forming a skin on the surface and lumps at the bottom, so it wants a warm drink or the whisk method, a paste made with a little liquid first and the rest added, a small chore every day for years. Line four, the taste. Some marine collagen powders leave a faint fishy or gelatinous note in plain water, present from the first mouthful and no fainter at week six because it is the powder's property and not the palate's, fixed by a coffee, a smoothie or a soup rather than by time, and absent from a capsule. Four lines in and none of them is a side effect of collagen; each is a cost of buying collagen as a powder, paid daily.

Line five, the flavour. Because of line four, many powders come flavoured, and a flavoured collagen powder carries sugar, several grams a serving in some, or sweeteners and flavourings in others, added to hide a taste the capsule never has, so a reader who chose collagen over a sweet drink for their skin is drinking a sweet drink, and the gummy takes this line to its extreme at two to four grams of sugar a piece for a fraction of a gram of collagen. Line six, the tub. An opened tub of powder absorbs moisture from the air each time it is opened, cakes, and is best finished within a few months, while a sealed capsule bottle sits unbothered for the printed shelf life, a small line that matters to the reader who takes a dessertspoon and finds the kilo tub still half full at month eight. Line seven, the shake. Most collagen powder in a lifter's kitchen goes into the whey shake, where it is stirred in and then blamed: the bloating from the whey's lactose, the acne the dairy literature associates with whey through insulin signalling, the fullness of forty grams of mixed protein at once, all land on the collagen because it was the thing added last, and a reader who wants to know what the collagen does drinks it alone for a fortnight. Line eight, the price, which is the powder's one advantage and the reason to buy it anyway: per gram of collagen, powder in a large tub is the cheapest form on the shelf, so a reader running the joint trials' ten grams a day for six months or the tendon protocol's fifteen before each session buys powder because the capsule cannot reach those grams affordably, and accepts the seven lines above as the price of the eighth. The secondary question, the side effects of collagen powder for women, has the same list as for anyone, because no collagen trial found anything sex-specific: fullness and bloating at scoop doses fading over a fortnight, the oxalate footnote for calcium stone formers, fish allergy with marine, and nothing else above placebo in trials whose participants were mostly women, so the women's version of this page is this page. The format scored: the powder wins on price per gram at trial doses and loses on the other seven lines; the gummy loses on all eight and adds sugar; and the capsule sidesteps six of the eight, the scoop, the measure, the clumping, the taste, the flavour and the shake, at a dose that is modest and has to be stated as such. The worked example is that capsule on its true terms: two capsules, 1200mg hydrolysed type 1 marine collagen with 12mg vitamin C plus zinc, 120 for £16.99 at 28p a day, lab tested and UK made, a measured dose below the research band taken for vitamin C's collagen formation sentence, with none of the tub's chores. What is the downside of taking collagen powder: the scoop, the measure, the clumps, the taste, the sugar, the shelf life and the shake, in exchange for the cheapest grams on the shelf.
