Collagen Supplements: Hype or Helpful?
Collagen has become one of the most talked-about supplements in the beauty and wellness world — and for good reason. As we age, our natural collagen production declines, leading to fine lines, wrinkles, joint stiffness, and reduced skin elasticity. But with so many collagen products on the market, it’s natural to ask: are all collagen supplements the same?
The short answer? No — and the differences matter.
What Is Collagen?
Collagen is the most abundant protein in the human body, making up around 75% of your skin and a significant portion of your joints, ligaments, and connective tissues. It acts like scaffolding, keeping skin firm and joints supple.
There are at least 28 types of collagen, but Type I, II, and III are the most relevant for skin, bones, and joints.
Types of Collagen in Supplements
Not all collagen supplements contain the same type — and each type serves a different function:
| Collagen Type | Found In | Benefits |
|---|---|---|
| Type I | Skin, bones, tendons | Skin firmness, anti-ageing |
| Type II | Cartilage | Joint support |
| Type III | Skin, muscles | Skin elasticity, gut health |
Most beauty-focused collagen supplements contain Type I and III, while joint health formulas often include Type II.
Marine vs Bovine vs Porcine Collagen
The source of collagen also affects its quality and absorption:
Marine Collagen (from fish): Rich in Type I collagen. Known for high bioavailability and skin benefits.
Bovine Collagen (from cows): Contains Type I and III. Good for skin, hair, nails, and gut health.
Porcine Collagen (from pigs): Similar to bovine, but less commonly used in premium supplements.
Marine collagen peptides are often considered the most effective for skin rejuvenation due to their smaller molecular size and better absorption.
Hydrolysed Collagen (Collagen Peptides) – What Does It Mean?
Look for the term “hydrolysed collagen” or “collagen peptides” on the label. This means the collagen has been broken down into smaller chains (peptides) that are easier for your body to absorb.
Without hydrolysis, collagen is harder to digest and less bioavailable.
Ingredients to Look For
A good collagen supplement should ideally also contain:
Vitamin C – essential for collagen synthesis
Hyaluronic Acid – supports skin hydration
Zinc & Biotin – promote skin, hair, and nail health
Avoid products with added sugars, artificial colours, or unnecessary fillers.
Powder, Capsules, or Drinks – Does Form Matter?
The form you choose depends on personal preference, but:
Powdered collagen peptides often provide higher doses per serving and can be easily mixed into smoothies or water.
Liquid collagen may be more convenient, but often contains lower doses and added sweeteners.
Capsules are easy to take but may require multiple pills to reach an effective dose (5,000–10,000 mg daily).
Is There Any Scientific Evidence?
Yes — several UK and international studies have shown that daily collagen supplementation (especially hydrolysed Type I collagen) can:
Improve skin hydration and elasticity
Reduce the appearance of fine lines
Support joint and bone health
However, results vary, and consistency is key. Most studies show visible improvements after 8–12 weeks of daily use.
Final Thoughts: Are All Collagen Supplements the Same?
Definitely not. When choosing a collagen supplement, consider:
✅ The type of collagen
✅ The source (marine vs bovine)
✅ Whether it’s hydrolysed
✅ The supporting nutrients included
✅ The dose (ideally 5,000–10,000 mg per day)
At BHA, we only recommend evidence-based supplements that meet UK quality standards and support your skin and wellness goals.
