How Much Collagen Should You Take a Day?

Most research on collagen uses a daily dose of 2.5g to 10g. Around 8g sits near the top of that range, so it's a generous daily amount. Every Naturally Collagen sachet gives you 8,000mg (that's 8g) of marine collagen, along with 180mg of Vitamin C, which contributes to normal collagen formation.

So the simple answer is this: aim for a daily dose somewhere inside that 2.5g to 10g window, and take it every single day. The rest of this guide explains where the range comes from, whether 8,000mg is genuinely "enough", and why the type of collagen you choose matters just as much as the amount.

The short answer: how much collagen per day?

Collagen studies don't all use the same dose, but most of them land inside a fairly narrow band. Here's what the research tends to use:

Two things are worth noticing. There's no single magic number; it's a range. And the exact amount matters less than one simple habit, which is taking it every day. Your body is always using its collagen up, so a daily top-up is really the whole point.

That's why Naturally Collagen comes as one sachet a day. There's nothing to scoop and no dose to guess at. You get a measured 8,000mg every time.

Is 8,000mg of collagen enough? And is more actually better?

8,000mg (8g) sits near the top of the doses used in research, so it's a genuinely generous daily serving rather than a token sprinkle.

Now for the honest part: more isn't automatically better. Once you reach a sensible daily dose, taking very large amounts hasn't been shown to add much. Your body can only make use of so much collagen at a time, so a huge number on the label is rarely the advantage it looks like.

Three things matter far more than a big headline figure:

• Taking it daily. A steady dose every day beats an occasional large one.
• Collagen that's easy to take. Ours is hydrolysed, which simply means it's been broken down into small pieces called peptides, so it dissolves into a drink instead of sitting as a gritty powder.
• The Vitamin C that comes with it. This is the part most people overlook, and it deserves its own section below.

Why the type of collagen matters, not just the amount

Not all collagen is the same, and two details are worth understanding.

The first is where it comes from. Ours is marine collagen, sourced from fish rather than cattle. Marine collagen is mostly Type I, which happens to be the main type of collagen found in your skin.

The second is the quality of the collagen itself. Naturally Collagen is made with Peptan, a marine collagen peptide that has been clinically studied. When you read about collagen research, this is usually the kind of studied ingredient the science is referring to, rather than an unnamed powder. We look at this properly in our guide to marine collagen and in the science behind Naturally Collagen. The takeaway is straightforward: a studied ingredient at a daily dose beats a bigger number of something you know nothing about.

Don't forget the Vitamin C

Here's the detail that's easy to miss. Vitamin C contributes to normal collagen formation. That's an officially approved statement, and it reflects something real, because your body genuinely needs Vitamin C to build collagen of its own.

So a collagen drink that includes Vitamin C is doing something sensible. Each Naturally Collagen sachet contains 180mg of it, which is roughly three times the amount found in some other collagen drinks. It's a small addition that quietly does real work.

How to take your daily collagen

The routine could hardly be simpler:

• One sachet a day. Drink it neat, or stir it into water or juice.
• At any time of day. Morning or evening, whichever you'll actually remember and stick with. We cover the timing question in best time to take collagen.
• Every day. Consistency really is the whole game.

How long before you notice a difference?

Collagen is a slow build rather than an overnight fix. Most people who take it daily give it a full 8 to 12 weeks before deciding whether it suits them, which is also the window used in most studies.

We're confident enough in that daily habit to back it with a results guarantee. Take one sachet a day for the full course, and if you're not happy, our UK team will put it right. You can read how the guarantee works and how long collagen takes to work if you'd like the detail.
