Is more collagen better? The honest answer

Walk the collagen shelf and the numbers climb: 5,000mg, 8,000mg, 10,000mg, and then the ones that shout a bigger figure still. Beyond Collagen+ sits at the generous end — 7,500mg in The Everyday, 15,000mg in The Flagship, both in a 100-millilitre bottle. So the fair question, the one careful label-readers ask us most, is simple: is more collagen actually better? The honest answer is the kind the supplement aisle rarely gives. Up to a point, yes. Past that point, no — more becomes more collagen, not more results.

We sell the bigger bottle, and we would still rather you understood the number than be impressed by it. So here is what the research has actually measured, where the evidence is solid, where it thins out, and what no milligram count can buy.

What the number on the label means

The milligrams on a collagen label count the collagen in the serving. Whatever form it takes — a hydrolysed peptide powder, or, in our case, whole collagen brewed fresh from fish scales — your body does the same thing with it once you swallow: digestion breaks it down into amino acids and small fragments, the building blocks your body uses to make its own collagen. The number is the input. What your body builds from it is its own decision — and that is exactly where the simple "more in, more out" picture falls apart.

When trials test whether oral collagen "works," they mostly measure skin: hydration, elasticity, the look of fine lines, over eight to twelve weeks. The better-designed studies find effects that are modest but real. And crucially, the dose-response is not a straight line. More collagen does not produce proportionally more effect. The curve climbs steeply at low doses, more gently in the middle, and then flattens — plateaus — somewhere, even if no study has pinned the exact spot.

What the research has actually used

The window most peer-reviewed studies fall inside is 2.5 to 10 grams a day. That is where the evidence base lives.

At the lower end, Proksch and colleagues (2014, Skin Pharmacology and Physiology) gave 2.5 grams of collagen peptides daily for eight weeks to older women and measured significant improvements in skin elasticity versus placebo. The same group, in Journal of Medical Food that year, reported reduced eye-wrinkle depth at the same 2.5-gram dose. Bolke and colleagues (2019, Nutrients) used 2.5 grams with added vitamins and minerals over twelve weeks and again found measurable skin improvements.

In the middle, Inoue and colleagues (2016, Journal of the Science of Food and Agriculture) compared 5-gram and 10-gram doses over twelve weeks for skin endpoints. Both worked; the 10-gram arm did slightly better, but the gap was smaller than the doubling of dose would suggest.

At the upper end, Asserin and colleagues (2015, Journal of Cosmetic Dermatology) used 10 grams of fish-derived collagen peptides daily for eight weeks; skin moisture and dermal collagen density both rose significantly versus placebo. The pattern across all of it is consistent: 2.5 grams produces measurable effects, especially in older participants whose own collagen-making has already slowed; 10 grams produces slightly larger ones; the difference between 5 and 10 grams is real but not dramatic. The 2.5-to-10-gram range is the well-paved part of the road.

One honest caveat runs through every study above: they were done on hydrolysed peptides — the powdered form — not on a whole, fresh brew like ours. We think the dose lesson still transfers, because it is a lesson about how much collagen a body can put to use, not about the form it arrived in. But we would rather flag that than quietly borrow the research as if it were run on our bottle.

Above 10 grams — what the evidence does and does not say

Above 10 grams, the published research thins out considerably. The studies that exist tend to be smaller, focused on specific groups, and rarely run a head-to-head against a 10-gram arm in the same protocol.

Zdzieblik and colleagues (2017, British Journal of Nutrition) tested a 15-gram daily dose in athletes over twelve weeks — but justified the dose by body mass and training load, not by measuring it against 10 grams in the same study. A handful of smaller trials have looked at 12 to 15 grams for skin, with positive but not overwhelming results.

So the honest framing for everything above 10 grams: this is not a region where the dose does nothing — a larger body uses more in absolute terms. It is a region where the extra benefit per gram is unclear. No single study has shown that 15 grams does measurably more for your skin than 10. What the higher dose buys is margin: a cushion above the threshold, room for the natural variation between people, a little compensation for the slower collagen-making of older bodies. Margin is real. It is simply not the same thing as "works better".

So why do we offer 15,000mg at all?

If more is not more results, why make the Flagship? Two honest reasons.

First, generosity you can see. The Flagship is, as far as we know, the most generous collagen pour on the market — and for some people that is exactly the point. A gift should feel abundant; someone buying the best for their mother, or for themselves, is allowed to want the most generous bottle in the room. We simply will not tell them it works better than The Everyday, because it does not. It is more collagen, not more results.

Second, the bodies asking for it. Our own collagen-making slows with age — very roughly one to one-and-a-half per cent a year after twenty-five, faster after menopause. For a woman in her fifties or sixties, the higher dose is a wider margin over a lower baseline. That is reassurance more than mechanism — but reassurance, honestly named, is a fair reason to choose a bottle.

What a bigger number does not buy

It is worth being just as plain about what the higher dose does not do, because the industry has trained us to read a milligram count as a quality score it is not.

It is not a magic threshold. Your body can only put so much collagen toward skin, hair and nails at once; the rest is used like any other protein. Doubling the milligrams does not double the effect. The plateau is real, even if its exact location is not.

It is not a faster timeline. Every study above ran on eight-to-twenty-four-week protocols, because your skin renews on a slow clock at any dose. Someone who feels a change in the first week or two is usually responding to the ritual, the hydration, or hope itself — not to new collagen, which takes its time.

It is not a substitute for the basics. Sleep, staying out of the midday sun, eating enough protein, and moving your body do more for your skin over a decade than any collagen at any dose. A 15-gram bottle on five hours of sleep and no sunscreen will do less than a 7,500mg bottle on eight hours of sleep and daily SPF.

And it is not better than The Everyday for most people. If your body is making collagen well, 7,500mg sits squarely in the middle of the proven 2.5-to-10-gram range. It is a full, generous dose — nothing skimped.

Choosing between The Everyday and The Flagship

Choose by what your body — and your reason — are actually asking for, not by the headline number.

• Most people start with The Everyday (7,500mg). It sits in the middle of the range the research is built on — a full, clinically meaningful dose, nothing skimped. It is the one we recommend.
• Reach for The Flagship (15,000mg) if you want the most generous bottle — as a gift, or because you are past fifty and like the wider margin. More collagen, not more results.
• Either way, the dose you actually drink beats the dose on the label. A 15-gram bottle half-finished in the fridge does less than a 7,500mg bottle you finish every morning. Consistency is the whole game — give it 90 days, and remember results vary from person to person.

How to take it

A few practical questions come up often enough to answer here.

Can you split a bottle across the day? You can, but there is no clear reason to. The research is on once-daily dosing, and the brew is made to be drunk in one sitting — in the morning, before food. That is simply how the studies were run, and the easiest habit to keep.

Should you add vitamin C? It is a sensible habit. Vitamin C contributes to your body’s own normal collagen formation, so we suggest taking the bottle with some — a squeeze of lemon, or a vitamin-C-rich breakfast alongside. The goji and red dates in the brew carry only a trace, much of it lost to the long simmer, so we would rather you topped it up than counted on the herbs for it. More on the building-blocks idea in the story of how the jelly works.

And timing? Morning, on an empty stomach, one bottle a day is what the research most closely supports. But if you forget and drink it at lunch, drink it at lunch — consistency matters far more than perfect timing.

Where Beyond Collagen+ lands

The dose conversation gets muddled because the industry trains us to read a milligram count as a proxy for quality. The honest version is more careful. There is a wide window — 2.5 to 10 grams — where the research is solid and the effect is real, and above it, more buys margin rather than a measurably better result. Below 2.5 grams, you are likely under the threshold.

Beyond Collagen+ gives you both ends of the sensible range: The Everyday at 7,500mg, squarely in the proven window and the one we recommend, and The Flagship at 15,000mg for those who want the most generous pour. Both are the same whole collagen, brewed fresh from fish scales with the same herbs, halal-supplier sourced (HALVEC verified; JAKIM certification in process). Neither replaces sleep, sun sense, or enough protein — and both, chilled overnight, do the one thing a powder at any milligram count cannot: set into a jelly you can see.

If you are weighing the two, the FAQ covers the practical questions, our piece on whole collagen vs hydrolysed peptides goes deeper on form, and fish scale vs marine vs bovine on source. Or look at the two doses of the same brew: The Everyday (7,500mg) and The Flagship (15,000mg).
