What's Noticed After Using Naturally Collagen®

Science Inside – Peptan® Marine Collagen

Naturally Collagen® uses Peptan®, the gold-standard marine collagen clinically proven to boost skin hydration and elasticity. Every 15 ml sachet delivers visible results, powered by science and manufactured in-house for absolute quality.

  • ✧ 8,000 mg low-molecular-weight (2 kDa) Peptan® collagen peptides.
  • ✧ 95% absorption for visible results within 30 days.
  • ✧ Clinically proven to improve skin elasticity & hydration within 8 weeks.

What is Peptan®?

Peptan® is the world’s leading brand of bioactive collagen peptides – a natural, clinically tested ingredient developed by Rousselot, the global leader in collagen science.

Each sachet of Naturally Collagen® contains 8,000 mg of Peptan® marine collagen peptides, the same peptide profile used in numerous published clinical studies on skin health, joint comfort, and recovery.

Why Peptan® is different

  • ✧ Clinically researched: Multiple peer-reviewed studies show Peptan® peptides improve skin elasticity, hydration, and reduce wrinkles after 8–12 weeks of daily use.
  • ✧ High bioavailability: Peptan® peptides have a low molecular weight (~2 kDa), allowing them to be easily absorbed and distributed throughout the body.
  • ✧ Made from traceable freshwater fish, produced in France under the highest safety and environmental standards.

The results

In clinical studies, women taking Peptan® experienced measurable improvements in skin elasticity and hydration after just 8 weeks, with continued improvement through 12 weeks of daily use.

Customer Reviews

Overall rating: 4.7 / 5 from 146 reviews.

The best I’ve tried so far 10/10 * I’ve been using another well known brand so had nothing to compare it to till I saw an offer for naturally collagen. I’m into week 2 of using it & can already see the difference in my skin & hair. It tastes great & has a sparkly shine to the liquid which makes it look rich. Good consistency so easy to swallow straight from the handy little sachets. Unfortunately and I say this with great sadness I cannot afford to purchase regularly at the normal price it’s just too expensive for my budget. If I won the lottery I would buy it in bulk!

Naturally Collagen® Premium Peptan® Liquid Marine Collagen – Natural Tropical Flavour

For me this is the best collagen I have tried. It doesn't have the best taste but is edible. I find it easier to take than powders/tablets and I have noticed a difference in myself particularly in the rate that my nails grow. I think it has helped reduce hair fall as well. Just a note that I had a batch that expires Aug 2026 that I must have accidentally put to the back of my cupbpard as I opened the pack last week (1st June 2026) and they tasted awful! My advice is don't let them get close to expiry.

Frequently Asked Questions

How soon will I see visible results?

Most users begin to notice smoother, more hydrated skin within 8 weeks of daily use. Some report subtle changes by week 4 (lighter fine lines, improved texture). To maintain your glow, continue using one sachet a day.

Can I cancel or pause my subscription anytime?

Yes - there’s no minimum term. You can pause or cancel your subscription easily via your account dashboard or by contacting our support team. Billing stops from your next scheduled delivery.

Is Naturally Collagen® safe for pregnancy, breastfeeding or medical conditions?

Our formula is sugar-free, gluten-free, dairy-free and contains no artificial nasties. However, if you are pregnant, breastfeeding, taking prescription medication or have an underlying medical condition, we recommend consulting your doctor before use.

How should I take it and can I mix it with other drinks?

Take one 15 ml sachet daily. You can drink it straight or mix it into water or juice (cold or room-temperature). For best absorption, avoid adding it to very hot drinks (above 60 °C) which may affect peptides’ effectiveness.

What ingredients are included and is it suitable for vegetarians/vegans?

Each sachet contains 8,000 mg of premium marine collagen peptides (type I & III) plus 180 mg vitamin C (calcium ascorbate). It is not suitable for vegetarians or vegans, as the collagen is sourced from freshwater fish. Free from gluten, dairy, bovine/porcine products, added sugar, artificial sweeteners, artificial colours and flavours.

Why 8,000 mg and why marine collagen?

Our 8,000 mg dose uses patented marine peptides (hydrolysed to ~2 kDa) for superior absorption (up to 95 %). We selected marine collagen for its effectiveness in skin, hair and nail support and our freshwater sourcing reduces heavy‐metal risk.

What results can I expect besides skin?

Many users report additional benefits including stronger hair, healthier nails, and less joint discomfort when taken consistently. These secondary results typically show after 6–10 weeks’ use.

What shipping options and delivery times are available?

Orders placed before 1 pm UK time (Monday–Friday) are usually dispatched same day. UK standard delivery takes 2-4 working days. Free UK shipping is available on all one-time and subscription orders.

Can I change my delivery frequency, skip or pause my subscription?

Yes – via your account dashboard you can change the delivery interval, skip a shipment or pause your subscription at any time. If you need help just contact our support team.

How is the collagen sourced and what sustainability credentials does it have?

The marine collagen is sourced from freshwater fish in France, enzymatically hydrolysed to 2 kDa peptides. We ensure low sodium/mercury contamination. The product is made in the UK under strict quality standards. We use recyclable sachets and partner with a carbon‐offset programme.

What if I’m using skincare products or topical treatments – can I still take Naturally Collagen®?

Absolutely. Our drink works from the inside-out and complements topical skincare. Whether you’re using retinoids, peptides, or vitamin C serums, you can still benefit. For best results, take one sachet daily along with your regular routine.
