Collagen & Peptides – What you Really Need to Know

As a nutritionist supporting women 40+, one f the questions I get asked most often is:

“Should I be taking collagen?”

Honestly, it depends.

Supplements are never a one size fits all, and what works for one person may not be right for another. But recently collagen has become one of the most talked about wellness supplements, especially for skin, joints, hair, nails and healthy ageing.

So let’s simplify the science and look at what collagen actually is, what peptides are and whether supplements really are worth considering.

What is Collagen?

Without becoming overly scientific, collagen is the main structural protein in the body. You can think of it as the ‘support system’ that helps keep skin firm, joints cushioned, bones strong and connective tissue healthy.

Collagen makes up around 30% of the body’s total protein. When collagen levels are healthy, skin tends to feel firmed and more elastic, joints move more comfortably and tissues repair more efficiently.

Why Does Collagen Decline?

Unfortunately, our natural collagen productions starts to slow down from our mid-to-late twenties onwards.

For women, this decline becomes much more noticeable during and after menopause due to falling oestrogen levels.

Common signs of collagen decline may include:

• Fine lines and wrinkles

• Thinner or less elastic skin

• Joint stiffness

• Slower recovery

• Brittle Nails

• Changes in hair texture

Lifestyle factors can also accelerate collagen loss, including:

• Excess sun exposure

• Smoking

• High Sugar intake

• Chronic stress

• Poor Sleep

• Nutrient deficiencies

This is one reason why supporting collagen production through nutrition and lifestyle can be increasingly important as we age.

Different Types of Collagen Simplified

There are many different types of collagen in the body. The main ones people know about through supplements are:

Type 1- Skin, Hair & Bones

This is the most common type of collagen in the body. It supports:

·Skin firmness and elasticity

·Hair and nail strength

·Bones

·Tendons and ligaments

This is the type most commonly found in beauty focussed collagen supplements.

Type II – Joints and Cartilage

Type II collagen is mainly found in cartilage. It is often used in supplements aimed at:

·Joint support

·Mobility

·Osteoarthritis support

·Active

Type III – Skin and Connectivity Tissue

Type III works alongside Type 1 and supports:

·Skin Structure

·Blood Vessels

·Muscles

·Organ Support

What Are Collagen Peptides?

Collagen peptides are simply collagen that has been broken down into smaller pieces so the body can absorb it more easily.

These smaller pieces dissolve well in drinks and are commonly sold as powders, capsules or sachets. You may see them labelled as:

• Hydrolysed collagen

• Collagen hydrolysate

• Marine Collagen peptides

Once absorbed, these peptides provide the body with amino acids and may help stimulate the body’s own collagen productions.

Does Collagen Supplementation Actually Work?

Research on collagen has grown significantly over the last few years, particularly around skin and joint health.

Current evidence suggest collagen supplementation may help support:

• Skin Hydration

• Skin elasticity

• Fine lines and wrinkles

• Joint comfort

• Cartilage support

However, it is important to keep expectations realistic.

Collagen is not a miracle cure and results are usually gradual rather than dramatic. Most studies showing benefits involved daily use over several weeks or months.

Consistency matters more than taking high doses.

Marine vs Bovine Collagen- What is the difference?

Clients often ask whether marine or bovine collagen is better. The truth is both can be effective.

Not all collagen supplements are the same. The form of collagen matters significantly depending on your goal.

Marine Collagen

Usually sources from fish and often promoted for skin support, hair and nails and easier absorption.

Bovine Collagen

Usually sourced from cows. Often used for skin, bones, joint support and general collagen support

The best choice often comes down to:

• Personal preference

• Dietary needs

• Sustainable considerations

• Product quality

What Helps Collagen Work Better?

Collagen supplements work best when the body also has the nutrients needed to build collagen naturally. Important nutrients include:

• Vitamin C (Ascorbic Acid)

• Zinc

• Copper

• Protein

• Amino Acids

Simple ways to support collagen naturally include:

• Eating enough protein

• Including colourful fruit and vegetables

• Managing stress

• Prioritising sleep

• Stay hydrated

• Protecting yourself from the sun

Small lifestyle habits make a difference over time.

Choosing a Collagen Supplement

If you are considering collagen supplementation look for:

• Clear ingredient lists

• Third party testing where possible

• Added vitamin C

• Minimal fillers and sweeteners

• A form suited to your goals

For example:

• Skin focused products often contain Types I and III

• Joint focused products may contain Type II collagen

Powders tend to be the most versatile and are easy to add to tea, coffee, smoothies, yoghurt, porridge etc.

A Balance View on Collagen

Collagen supplementations can be a helpful support tool for some people, particularly during midlife and menopause when natural collagen production declines more rapidly.

That said, supplements should never replace the foundations of health:

• Good Nutrition

• Strength training

• Good quality sleep

• Stress Management

• Hydration (are your cells at their optimal level for hydration)

Think of collagen as one piece of a wider wellbeing picture, it’s not a quick fix.

Final thoughts

Collagen is one of the body’s most important structural proteins and natural production declines with age.

While supplements are not essential for everyone, some people do notice improvements in skin hydration, nail strength or joint comfort when taken consistently.

As always quality matters, consistency matters and supporting the body through a balanced lifestyle remains the most important step.
