Why 5,000mg of Marine Collagen is the Beauty Standard

At Tide, we believe that being good to yourself should be enjoyed, not endured. For too long, the collagen market has been defined by a medicine cabinet mentality… expensive supplement shots in plastic bottles that feel more like energy drinks than beauty products, or powders and sachets that are made sickly sweet to mask the taste of the collagen itself.

When our founder, Louise, a working mother and retail veteran with over 20 years of experience at Selfridges and Waitrose, set out to create Tide in January 2025, she was driven by a personal frustration. She was already a believer in collagen, but she couldn't find a product that felt like a premium ritual rather than a chore. Tide was born to bridge that gap: a delicious beauty water designed to nourish your hair, skin, and nails through a daily drink that tastes as good as it does good.

To achieve this, we focused on two pillars: provenance at heart and taste at the forefront. This led us to our Marine Collagen range, formulated with exactly 5,000mg of premium peptides. But in a market flooded with varying dosages, why is 5,000mg the gold standard for beauty?

1. Why do small molecules absorb better?

The efficacy of a collagen supplement isn't just about how much you swallow; it’s about how much your body can actually use. This is the concept of bioavailability.

Not all collagen is created equal. Our marine collagen is sourced exclusively from wild-caught North Atlantic fish. This source is predominantly Type I collagen, which targets and supports the structural matrix essential for firm, youthful skin, hair, and nails.

The Marine Advantage lies in the molecular structure. Marine collagen is 1.5x more bioavailable than bovine collagen because it consists of smaller peptides. These smaller molecules allow for faster, more efficient absorption and utilisation by the gastrointestinal tract. Because the body can process these peptides more effectively, a 5,000mg (5g) dose of marine collagen is incredibly potent, providing a concentrated delivery of the building blocks your skin needs most.

2. The 5g Threshold- Clinically Proven Results

We didn't arrive at the 5,000mg dosage by accident; we chose it because that is where the clinical evidence for skin health is most compelling. While our Bovine range utilises a 10,000mg dose to account for its lower bioavailability and its focus on muscle and bone integrity, the 5,000mg Marine dose is specifically optimised for the Beauty from Within customer.

Clinical studies have consistently shown that a daily intake of 5g of collagen peptides significantly enhances skin moisture and firmness. These results typically manifest within an 8 to 12-week window of consistent daily consumption. By providing 5,000mg in every can, Tide ensures you are meeting the threshold required to see measurable changes in skin hydration and elasticity.

3. Combatting the "Collagen Cliff"

Why is supplementation necessary in the first place? Biology dictates that our natural collagen production begins to decline around age 25. From our mid-20s onwards, we lose approximately 1% of our collagen every year. This decline is what eventually leads to the visible signs of aging, such as fine lines and loss of skin volume.

A daily 5,000mg dose of Tide acts as a proactive defence. By supplying the body with high-quality Type I peptides daily, you help maintain the structural integrity of the skin and support its natural renewal process. It is about maintenance and prevention, fitting effortlessly into a busy lifestyle so that you can stay ahead of the natural aging curve.

4. Beyond the Skin: Hair and Nails

The benefits of our 5,000mg Marine range extend beyond the complexion. Oral collagen supplementation has been scientifically linked to a reduction in nail brittleness and the promotion of healthier, thicker hair.

For the modern woman juggling work, family, and wellness our core audience of women aged 35–55- these holistic results are vital. She doesn't want a dozen different pills: she wants one effective, transparent, and credible solution that works for her entire beauty profile.

5. The Role of Vitamin C

At Tide, we don't just stop at collagen. Every can of Tide is powered by premium collagen + vitamin C.

Vitamin C is a non-negotiable partner for collagen because it is essential for collagen synthesis. Without adequate Vitamin C, the body cannot effectively turn those absorbed peptides into the new collagen fibres that keep skin firm. Additionally, Vitamin C acts as a potent antioxidant, protecting skin cells from the oxidative damage caused by the environment. This dual-action approach ensures that the 5,000mg of collagen in your Tide is being put to its absolute best use.

The Tide Difference

We know our customer. She is sophisticated and values a holistic approach to health. She is the woman you find in hotels, spas, and boutique gyms. She likely shops at Harrods or Fenwick, and she expects the products in her fridge to reflect the same quality as the skincare on her vanity.

Our Marine Collagen range… featuring Natural Raspberry and Natural Lemon & Lime… is designed to replace daily soft drinks with something functional and delicious.

Clean Labelling: We use only natural flavours and ingredients.
Sustainability: Our drinks are packaged in 100% recyclable cans, moving away from the plastic waste common in the supplement industry.
Low Calorie: At just 13 calories per can for our Marine range, it is a guilt-free addition to any wellness routine.
Transparency: We are open about our provenance, using MSC-certified wild-caught fish and ensuring our claims are nutritionist-backed.

Summary: Why 5,000mg?

In short: because it works. By choosing a 5,000mg dose of Marine collagen, Tide provides a highly bioavailable, clinically supported, and nutrient-dense drink that targets the specific concerns of our community. We have removed the frustration of supplementation (the bad taste), the clinical packaging, and the lack of provenance… and replaced it with a world where being good to yourself is a moment of genuine pleasure.

Whether you are reaching for a cold can of Natural Raspberry after a Pilates session or enjoying a Natural Lemon & Lime at your desk, you can trust that Tide is delivering the Beauty from Within results you deserve.
