After 40, collagen loss becomes one of the most visible changes in skin — and the supplement industry has responded with an overwhelming number of powders, capsules, and drinks all promising to turn back the clock. But do collagen supplements actually work? And if so, which ones are worth your money?
Here’s the honest, science-informed answer — and the best collagen supplements that are genuinely worth taking after 40.
What Happens to Collagen After 40?
Collagen is the most abundant protein in your body — it gives skin its firmness, elasticity, and plumpness. From your mid-20s, collagen production begins to slow. By 40, the decline is noticeable: skin loses its bounce, fine lines deepen, and the overall structure of the face begins to change.
After menopause, collagen loss accelerates sharply — studies suggest women lose up to 30% of skin collagen in the first five years post-menopause. This is why the visible changes in skin during this period can feel sudden and significant.

Do Collagen Supplements Actually Work?
The emerging evidence is more promising than the skeptics once suggested. Several well-designed clinical trials have found that daily supplementation with hydrolysed collagen peptides (collagen that has been broken down into smaller, more bioavailable fragments) can:
- Improve skin hydration and elasticity after 8–12 weeks of consistent use
- Reduce the visible depth of fine lines, particularly around the eyes
- Support nail strength and hair thickness
- Contribute to joint comfort — a secondary benefit many women over 40 appreciate
The key caveat: results are gradual and require consistency. Collagen supplements are not a quick fix — they work by providing the amino acid building blocks your body uses to synthesise new collagen. Think of them as raw materials, not a finished product.
🧴 Oily Mature Skin Note
Collagen supplements are an inside-out approach to skin health — they work from within rather than topically. If you have oily or acne-prone mature skin, look for formulas that don’t contain added sugars, flavourings, or biotin above 2500mcg (high-dose biotin has been linked to breakouts in some people). Unflavoured collagen powders added to coffee or smoothies are the cleanest option.
Best Collagen Supplements for Women Over 40
1. Vital Proteins Collagen Peptides
Best for: Everyday collagen powder | Form: Unflavoured powder
Vital Proteins is arguably the most recognisable collagen brand on the market — and their original unflavoured collagen peptides remain one of the best options. Sourced from grass-fed, pasture-raised bovine hide, it dissolves completely in hot or cold liquid and has no taste or smell. Each serving delivers 20g of hydrolysed collagen peptides alongside hyaluronic acid and vitamin C — two ingredients that work synergistically with collagen synthesis. Simple, clean, and effective.
2. Garden of Life Grass-Fed Collagen Beauty
Best for: Clean label, certified option | Form: Powder
Garden of Life’s collagen powder is certified paleo, non-GMO, and sourced from grass-fed bovine — with added biotin, vitamin C, and silica to further support skin, hair, and nail health. It’s one of the cleaner formulas on the market, free from artificial additives, and comes in both unflavoured and light vanilla options. A good choice for women who prioritise clean sourcing and certifications alongside their supplement routine.
3. Neocell Super Collagen Tablets
Best for: Capsule option for convenience | Form: Tablets
Not a fan of powders? Neocell’s Super Collagen tablets are one of the most popular capsule alternatives, delivering 6g of hydrolysed collagen type 1 and 3 per serving — the types most associated with skin, hair, and nail benefits. No mixing required, easy to take with breakfast, and widely available. A practical choice for women who want to add collagen to their routine without changing what they eat or drink.
4. Sports Research Collagen Peptides
Best for: Budget-friendly daily collagen | Form: Unflavoured powder
Sports Research offers a solid hydrolysed collagen powder that delivers 11g of collagen per serving at a very accessible price point. It’s non-GMO, sourced from grass-fed bovine, dissolves well in both hot and cold drinks, and has consistently strong reviews for improving skin texture and joint comfort after consistent use. If you want to try collagen supplementation without a large upfront investment, this is an excellent starting point.
5. Reserveage Marine Collagen Capsules
Best for: Marine collagen alternative | Form: Capsules
Marine collagen (sourced from fish) is considered by some researchers to have superior bioavailability compared to bovine collagen — meaning it may be absorbed more efficiently by the body. Reserveage’s marine collagen capsules combine type 1 collagen with hyaluronic acid and antioxidant astaxanthin for a comprehensive skin-support formula. A good option for women who prefer marine sourcing or who have not seen results from bovine collagen.
How to Take Collagen Supplements for Best Results
- Be consistent — daily supplementation for at least 8–12 weeks is needed to see skin results. Sporadic use delivers little benefit.
- Take with vitamin C — vitamin C is required for collagen synthesis. Taking your supplement with a glass of orange juice or alongside a vitamin C supplement maximises effectiveness.
- Morning or evening — timing doesn’t matter significantly. Choose whichever fits your routine best and stick to it.
- Combine with topical actives — collagen supplements work best alongside topical retinol and vitamin C, which also stimulate collagen production from the outside in.
💡 My Routine Tip
I stir Vital Proteins unflavoured collagen peptides into my morning coffee — it dissolves completely with no taste at all. After about 10 weeks of daily use I noticed my skin looked notably more hydrated and plump, and a few of my deeper forehead lines had softened. Hair and nails also felt stronger. It’s now a non-negotiable part of my morning routine alongside my topical skincare.
Final Thoughts
Collagen supplements aren’t magic — but they’re no longer just marketing either. The clinical evidence has matured alongside the market, and daily hydrolysed collagen is now a genuinely reasonable addition to a mature skincare strategy. Pair it with your topical vitamin C and retinol for an inside-and-outside approach to collagen support after 40.
Start with Vital Proteins or Sports Research for an accessible entry point. Give it three months before assessing results — patience is the secret ingredient here.
