Movement changes before you realise why.
One day you notice your knees feel stiffer getting out of the car.
Your shoulders take longer to loosen up after sleep.
Exercises that once felt comfortable leave you feeling more achy than they used to.
It's easy to assume that's simply part of getting older.
But one of the biggest changes happening beneath the surface is a gradual loss of collagen.
From our thirties onwards, collagen production naturally declines by around 1% each year. Around menopause, falling oestrogen accelerates that process because oestrogen plays an important role in maintaining the cells responsible for producing collagen.
Most conversations about collagen focus on smoother skin. When it comes down to collagen for women over 40, we're focused on something else.
Collagen for joints that let you keep walking, lifting, travelling, exercising and saying yes to the life you want to live.
Hair, skin and nails matter too. But movement is what protects your independence.
Collagen powder is a supplement that provides the amino acids your body uses to produce collagen — the protein that supports joints, tendons, ligaments, skin, hair and nails.
Collagen powder isn't a miracle ingredient, nor does it replace good nutrition or regular strength training. It is, however, one evidence-backed way to support the connective tissues your body relies on every single day.

What is collagen?
Collagen is the most abundant protein in the human body.
Think of it as the framework that helps hold everything together.
It provides structure and strength to:
- Cartilage in your joints
- Tendons and ligaments
- Bones
- Skin
- Blood vessels
- Muscles
- The lining of your digestive tract
There are more than 20 recognised types of collagen, but three are particularly relevant during midlife. Type 1, 2 and 3 account for the vast majority in the body. Collagen powder is typically made from hydrolysed collagen, also called collagen peptides. Hydrolysed collagen powders usually provide Type I and III collagen, while specialised joint supplements may contain Type II collagen.
| Type | Found in | Why it matters |
|---|---|---|
| Type I | Skin, bone and tendons | Supports skin strength, bone and connective tissue |
| Type II | Cartilage | Supports joint cushioning and mobility |
| Type III | Skin, muscles and blood vessels | Supports tissue structure and repair |
Why does collagen decline after menopause?
Collagen production slows naturally with age. The steepest decline typically occurs in the first few years after menopause. Studies suggest women can lose up to 30% of their skin collagen in the first five years after menopause.
As oestrogen levels fall, the activity of fibroblasts—the cells responsible for producing collagen—declines.
That means your body gradually replaces collagen more slowly than it's being broken down. The effects of menopause collagen loss appear throughout the body.
You may notice:
- Stiffer joints - particularly noticeable in the morning
- Reduced flexibility - putting on shoes may become more difficult
- Longer recovery after exercise
- Changes in skin elasticity - the appearance of fine lines
- More brittle nails - breakage and flaking
- Hair that feels thinner and drier, lacks bounce and shine
These changes don't happen overnight. They build gradually, which is why many women describe feeling less resilient rather than simply "older.”
Collagen For Joints And Movement In Menopause
This is where the strongest practical evidence sits. Cartilage — the cushioning tissue in your joints — is largely made of collagen, as are the tendons and ligaments that hold everything in place. In fact, collagen makes up around 70% of cartilage dry weight, making it essential for joint cushioning, mobility and structural integrity. As collagen levels decline, that cushioning gradually changes — which is why joint support is where the strongest practical evidence for collagen supplementation sits.
While collagen powder won't rebuild damaged joints overnight, research suggests that regular supplementation may help support joint comfort and improve function, particularly alongside regular exercise.
When collagen levels drop, your joints may feel less cushioned and more achy — particularly with movement. This is where collagen supplementation shows the most promise. Studies suggest that taking 10-20g of collagen peptides daily may help:
- Support joint comfort and mobility
- Improve flexibility and range of motion
- Support the structural integrity of cartilage, tendons and ligaments
The evidence is strongest for joint support, particularly when combined with regular movement and exercise.
Collagen, Muscle And Healthy Ageing For Women Over 40
Muscle and collagen work together. A simple way to look at it is muscles create force and collagen transfers that force through tendons and ligaments.
Women can lose up to 3–8% of muscle mass per decade after 30, with losses accelerating after menopause. This muscle loss has a clinical name — sarcopenia — and it accelerates after menopause in ways many women aren't warned about. If this resonates, our guide to sarcopenia and menopause covers what's happening and what you can do.
That's why we don't see collagen as a beauty supplement. We see it as part of supporting the systems that keep you moving. Collagen synthesis doesn't happen in isolation. Your body needs vitamin C to convert the amino acids from collagen into usable collagen fibres — without it, the process stalls.
Our collagen powder doesn't contain vitamin C, but our Rebalancing Shake does — with a high-strength dose designed to support exactly this process.
Strength training remains one of the most powerful things you can do for healthy ageing. Collagen may help support the tissues that allow you to keep doing it comfortably.

Collagen and Gut Health Women
Collagen is rich in glycine and proline — amino acids that play several important roles in the body, including supporting the structure of the intestinal lining, which is renewed continuously and relies on these proteins to maintain its integrity.
Research into collagen and gut health is still developing, but it's another reminder that collagen isn't simply about appearance. If you're interested in how menopause affects gut health more broadly, our guide to how menopause changes your gut microbiome explores this in more detail.
Nutritionist Insight
"Feeling more bloated is something many women notice in midlife. Hormonal changes can affect how your gut moves food along, slowing things down or making you more sensitive to foods that never used to bother you - all of which affects how comfortable digestion feels day to day."

What About Hair, Skin And Nails?
This is the benefit most people have heard about - skin support. The evidence is encouraging, particularly for skin hydration and elasticity.
Several studies suggest hydrolysed collagen can improve skin elasticity typically after 8-12 weeks of daily use. This is particularly relevant during menopause when skin elasticity changes noticeably.
When it comes to collagen for nails that have become more brittle the evidence for hair and nails is promising but most hair and nail studies are small or short-term. Some women notice improvements. Others don't.
That's why we'd rather be honest than make promises we can't support.
| Potential benefit | Strength of evidence |
|---|---|
| Joint comfort and mobility | Strongest and most consistent |
| Skin elasticity and hydration 1 | Moderate |
| Hair and nails | Emerging |
| Gut health and intestinal lining | Emerging / early stage |

Does Collagen Replace A Healthy Diet?
No. And no trustworthy brand should tell you otherwise. Collagen is one useful tool for women over 40.
But your body also needs:
- Enough daily protein to maintain muscle — collagen alone doesn't provide a complete amino acid profile
- Vitamin C to help build new collagen
- Regular strength training to challenge bones and muscles
- Fibre to support your gut microbiome - which affects everything from digestion to immunity
- Good overall nutrition to provide the nutrients every tissue depends on in menopause
This is why we think about nutrition as a system rather than a single ingredient. Everything works together. Sleep and stress management also matter — cortisol, the stress hormone, actively breaks down collagen, and poor sleep disrupts the repair processes your body relies on overnight. Managing both is part of supporting your connective tissues long term.
There's another factor worth knowing about: blood sugar. When blood glucose levels are consistently high, a process called glycation occurs — glucose molecules bind to collagen fibres, making them stiffer and more prone to damage. For women in midlife, when insulin sensitivity naturally declines, keeping blood sugar balanced isn't just about energy — it's also about protecting the collagen you have. You can read more in our guide to blood sugar balance and menopause.
How To Choose The Best Collagen Powder For Women Over 40
Not all collagen products are the same. When comparing products, look for:
Hydrolysed collagen peptides
Hydrolysed collagen has been broken into smaller peptides, making it easier to dissolve and absorb.
An effective daily dose
When it comes to collagen dosage, most studies use around 10g of collagen peptides per day, although some use slightly higher amounts. Most studies show measurable improvements after 8–12 weeks of daily use.
High-quality sourcing
Look for clearly stated sources and transparent manufacturing standards.
Minimal unnecessary ingredients
Avoid products loaded with artificial sweeteners or proprietary blends that don't disclose individual doses, fillers or ingredients that don't meaningfully contribute to the formulation.
Eve Biology Collagen Powder is formulated with these principles in mind — hydrolysed collagen peptides, a meaningful daily dose, and nothing unnecessary.
How to get the most from collagen
Unlike some supplements, collagen doesn't need to be taken at a specific time of day — consistency over weeks matters far more than when you take it.
Most people simply add collagen powder to:
- Coffee
- Smoothies
- Yoghurt
- Overnight oats
- Porridge
Try to include a source of vitamin C somewhere in your day—such as berries, kiwi fruit, citrus fruits or peppers—as vitamin C is needed for collagen synthesis.
And remember: Collagen works best alongside enough dietary protein. Your body still needs the building blocks to maintain muscle, connective tissue and healthy ageing.
Why We've Included Collagen At Eve Biology
We didn't develop an Eve Biology collagen product because it's fashionable. We developed our collagen powder for women in menopause and beyond because movement matters.
As women move through menopause, protecting muscle, joints and connective tissue becomes increasingly important. Our collagen is designed to sit alongside the nutritional foundations that make the biggest difference over time:
- High-quality protein
- Fibre
- Support for an active lifestyle
- Targeted nutrients where they're genuinely useful
We're not interested in helping you look younger. We're interested in helping you keep doing the things that make life feel like yours. Now is the time to build those foundations for your future. Explore Eve Biology Collagen Powder— formulated for women who want to keep moving, for longer.
Frequently Asked Questions
Does collagen powder actually work?
For joint comfort, the evidence is encouraging, particularly when taken consistently over several months alongside exercise. Evidence for skin is also supportive, while evidence for hair and nails is still emerging.
How long does collagen take to work?
According to clinical research most studies report noticeable improvements after around 8–12 weeks of daily use, although individual responses vary.
What type of collagen is best for joints?
Type II collagen is naturally found in cartilage, while hydrolysed collagen peptides (usually Type I and III) have also shown benefits for joint comfort in clinical studies. The best choice depends on the product and the outcome you're looking for.
Can collagen help with menopause symptoms?
Collagen isn't a treatment for menopause symptoms such as hot flushes or night sweats. It may, however, help support joints, connective tissue and skin, which can all be affected by declining oestrogen.
Is collagen powder safe?
Collagen supplements are generally considered safe for most healthy adults. If you're pregnant, breastfeeding or have a medical condition, speak to your GP or healthcare professional before starting any new supplement.
Should I take collagen with vitamin C?
You don't need to take them at exactly the same time, but having a good source of vitamin C somewhere in your day matters. Vitamin C is essential for collagen synthesis — your body uses it to convert the amino acids from collagen into usable collagen fibres. Without adequate vitamin C, that process is less efficient.
Good food sources include berries, kiwi fruit, citrus fruits and peppers. If you're using Eve Biology Collagen Powder alongside our Rebalancing Shake, the shake provides a high-strength vitamin C dose that supports this process as part of your daily routine.
