Let's talk about collagen

Your collagen production drops 1% every year after 35.

That is normal biology, not a failing. Between your late 30s and menopause, your body slows down its natural collagen synthesis by about a percent every year. By 50, most women have lost around 30% of the collagen they had at 25.

It shows up gradually. Fine lines that settle in for good. Hair that feels finer than it used to. Nails that split before they grow long. You noticed. That is not your imagination.

The good news is, you can help your body top it back up. That is what the next 8 to 12 weeks are for.

Here's the thing though

Your body still knows what to do with collagen.

Give it 2.5g of hydrolysed marine collagen and a supporting dose of Vitamin C every day, and it can rebuild what it has stopped making enough of on its own. That is the whole science of it.

  • 2.5g hydrolysed marine collagen per sachet The peptide form your body absorbs best, sourced from wild-caught fish.
  • Vitamin C in the same sachet Vitamin C contributes to normal collagen formation. Your body needs it to put the collagen to work.
  • A sachet, not a pill Mix one into water, coffee, tea or yogurt. Takes ten seconds a day. No hard to swallow pills.
  • Lemon & strawberry, actually pleasant No chalky aftertaste. The taste is why women stick with it long enough to see a difference.

Not magic. Just science, patience, and showing up for yourself.

By the founder

Why I made this.

As a GP, I kept having the same conversation. Women coming in worried about their hair, their skin, their nails. Almost always in their late 30s or 40s. Almost always well-informed and already taking supplements they had been told to take.

The problem was, most of what they were taking did not have the right dose or the right form to actually do anything. So I built the range I wished I could recommend. Evidence-based, dosed properly, and simple enough that you will actually take it every day.

The lemon and strawberry marine collagen sachet was one of the first I formulated. It is the one my patients ask me about most, and the one I take myself.

How to take it

Ten seconds a day. That is the whole routine.

No hard to swallow pills, no measuring, no shaker bottle. One sachet, one drink, one habit.

Tear open one sachet

One sachet a day, no measuring. Do not exceed 2 sachets per day.

Mix into your morning drink

Water, coffee, tea, yogurt or porridge. Dissolves cleanly. Tastes like lemon and strawberry, no chalky finish.

Repeat for 8 to 12 weeks

Consistency matters more than dose. Skin, hair and nail cells rebuild slowly. The women who see the biggest difference are the ones who show up every day.

Best in the morning. Take before or with food, first thing sets the habit.

A long game, not a quick fix

What actually changes, week by week.

Collagen is a slow build. Here is a realistic timeline of what women tend to notice, and when, so you know what to expect (and what to ignore) as the weeks go on.

Week 1 Baseline

Nothing visible yet, and that is normal.

Your body is absorbing the peptides and getting them to your skin, hair follicles and nail beds. This is the habit-forming week. Set the morning routine and let the biology start working underneath.

Week 4 Nails first

Nails start showing up first.

Nails have the shortest growth cycle of the three, so this is where women tend to notice the change first. Less peeling. Growing past the "always splits before it gets long" point. Small, but real.

Week 8 Hair follows

Hair follows next.

Two full hair growth cycles later, women describe hair that feels stronger at the root and less shed collected through the day. Nothing dramatic overnight. Just steadily better.

Week 12 Skin catches up

Skin catches up last.

Skin cells turn over the slowest, so this is the month. Most women describe a softer, plumper feel and the sort of glow that shows in photos before it is obvious in the mirror. The 3-month protocol is designed to land you here.

Beyond Keep going

Collagen is not a one-and-done.

Your body still loses about 1% of its collagen every year. The women who see lasting change are the ones who keep the daily sachet in the routine after week 12. That is why Subscribe & Save exists.

Individual results vary. Consistency matters more than dose. As with any supplement, consult your GP before starting if you are pregnant, breastfeeding or on medication.

Real talk

Every question we get asked.

Answers to the six questions new customers send us most. Not here? Reply to your order confirmation and a real person will get back to you.

What does it taste like?

Lemon and strawberry, and it dissolves cleanly with no chalky finish. It is not overly sweet, which most of our customers say they prefer. Mixes into water, coffee, tea, yogurt or porridge without changing the drink much.

Can I take it if I am pregnant, breastfeeding or on medication?

As with any supplement, please check with your GP first. Marine collagen is generally well tolerated, but we cannot decide that for you without knowing your history. If you are on medication, mention any supplements you take before blood tests too.

Is it gluten-free and coeliac-friendly?

Yes to both. Every sachet is gluten-free and coeliac-friendly. Manufactured and packed in Ireland to Irish and EU food standards.

How does the Subscribe & Save subscription work?

A fresh box ships automatically every 30 days at 10% off, with free shipping on every subscription order in Ireland and the UK (no order minimum). You can skip a delivery, change frequency or cancel any time from your account. No lock-in, no phone calls, no awkward save offers.

Can I take more than one sachet a day?

One a day is the standard dose. Do not exceed 2 sachets per day. Consistency matters more than dose, so taking one every day for 12 weeks will do more than doubling up for a week and then forgetting.

What is your returns policy?

Unopened products can be returned within 28 days for a replacement or refund. Just contact us and we will sort it out.
