Wondering if collagen supplements actually work? You’re not alone. From powders to gummies, collagen is one of the most buzzed-about beauty and wellness supplements on the market. But is it really worth the hype—or your money?
I take an inside-and-out approach to skincare—there’s rarely one magic fix. Instead, it’s a combination of good habits, quality products, and helpful supplements that, when layered together, deliver real results over time.
So today, we’re breaking down what collagen does, how it can benefit women over 40, and what to look for (and avoid) before adding another supplement to your routine.
What Is Collagen and Why Do Women Over 40 Need It?
Collagen is the most abundant protein in your body. It gives structure to your skin, strengthens hair and nails, supports joints, and keeps connective tissues resilient.
But starting in your mid-20s to early 30s, collagen production naturally declines. By the time you’re in your 40s, that drop becomes more noticeable—think:
- Fine lines and wrinkles
- Dull or dry skin
- Thinning hair
- Brittle nails
- Joint stiffness
This is where collagen supplements for women over 40 come in—promising to restore some of what we lose with age.
Different Types of Collagen Supplements
Not all collagen supplements are created equal. Understanding what you’re buying is key to seeing results.
🧬 Hydrolyzed Collagen (Collagen Peptides)
Easiest to absorb and most common in powders—ideal for skin, hair, and nails.
🐟 Marine Collagen
Sourced from fish. Known for skin-specific benefits and usually gentler on digestion.
🐄 Bovine Collagen
Bovine collagen is derived from cows and is one of the most common and effective sources of collagen supplements. It’s especially rich in Type I and Type III collagen, which are the types most beneficial for improving skin elasticity, supporting muscle tone, and promoting strong bones. It’s a popular choice for women over 40 because it targets many of the areas where we start to notice changes with age—like skin firmness and recovery after workouts.
🧪 Types I, II, and III Collagen Explained
Understanding the different types of collagen can help you choose a supplement that matches your specific goals. Here’s a quick breakdown of the three main types:
- Type I:
This is the most abundant form of collagen in the body. It plays a major role in maintaining skin firmness and elasticity, as well as the strength of tendons, ligaments, and bones. If your focus is on smoother skin, fewer fine lines, stronger nails, or healthier hair, Type I is key. - Type II:
This type is found mainly in cartilage, making it especially beneficial for joint health and flexibility. It helps cushion joints and support smooth movement, so if you’re dealing with stiffness or discomfort—especially in the knees, hips, or shoulders—Type II may help. - Type III:
Often found alongside Type I, Type III collagen supports the structure of skin, internal organs, and blood vessels. It plays a big role in skin’s hydration and smoothness, as well as the elasticity of organs and the circulatory system.
✅ Look for:
- Hydrolyzed or marine collagen
- Added Vitamin C for absorption
- Transparent labeling and third-party testing
Do Collagen Supplements Work for Women Over 40?
Here’s what research and experience say about collagen benefits for women over 40:
- May improve skin elasticity and increase hydration
- May reduce fine lines and give skin a smoother appearance
- Some women notice stronger nails and less hair breakage
- Possible joint pain relief when taken consistently
Important: Results aren’t instant. Studies suggest it takes 8–12 weeks of consistent use to see visible improvements.
What to Consider Before You Buy a Collagen Supplement
Before investing in any wellness trend, here’s what to keep in mind:
- Lifestyle matters. Smoking, poor sleep, sun exposure, and stress all contribute to collagen loss. No supplement will fully reverse those effects.
- Your diet may already support collagen production. If you eat a protein-rich diet with vitamin C, your body may already be producing enough naturally.
- Quality over hype. Fancy branding doesn’t always equal results. You want a clean label and proven ingredients.
What to Avoid in Collagen Supplements
Here’s what to watch out for when shopping:
❌ Artificial Sweeteners
Avoid sucralose, aspartame, and artificial flavors that can cause bloating or gut sensitivity.
❌ Proprietary Blends
If the label doesn’t tell you how much collagen you’re actually getting, skip it. Transparency is key.
❌ Overpromising Claims
Collagen won’t erase wrinkles or magically regrow hair. Be realistic—look for subtle support, not miracles.
❌ Poor Ingredient Sourcing
Choose grass-fed, pasture-raised bovine collagen or wild-caught marine collagen for better quality.
Pro Tip: Third-party certifications like NSF or USP are great signs of quality and safety.
My Personal Experience Taking Collagen After 40
I’ve been adding Vital Proteins Collagen Peptides to my morning coffee or smoothie every day for years. It started as one of the first habits in my wellness journey—an easy, no-fuss step that felt like a small investment in myself. I figured, if it helps even a little, why not?
But I really noticed the difference at the start of this year. Right before the holidays, I went in for my usual gel manicure—something I’d been doing every two to three weeks for a long time. My nail tech gently suggested I give my nails a break, saying they were starting to look worn down. She wasn’t wrong. When the gel came off in January, my nails were a mess—brittle, splitting, and barely growing.
Of course, the holidays had thrown off my routine, and I hadn’t been consistent with my supplements. So I got back to my daily collagen, and sure enough, I started to see a real improvement. It wasn’t overnight, but within a few weeks, my nails were stronger, stopped peeling, and started growing again. I also noticed a subtle difference in my hair—it felt just a bit thicker and shinier.
Nothing dramatic, but enough to make it worth sticking with. That’s the thing with wellness: it’s rarely one big change—it’s the small things, done consistently, that add up.
I keep a container of Vital Proteins Collagen Peptides next to my coffee, and recently realized they had had travel packs too.

So—Is Collagen Worth It for Women Over 40?
In my opinion? Yes, with the right expectations.
If you’re consistent and choose a high-quality product, collagen can support healthier skin, stronger nails, and better hair texture. But it’s not magic. Think of it as one more tool to support your well-being—not a cure-all.
I’m in my 40s, I live a full, busy life, and I’m not trying to look 25. I’m simply trying to feel good, look well-rested, and support my body as it evolves—and collagen plays a small, helpful role in that.
