It’s no secret that collagen supplements are everywhere.
They promise smoother skin, stronger joints, and shinier hair — and fortunately, our research into the best collagen supplements on the market found plenty of scientific studies to back up those claims.*
Beneath thriving skin, hair, and nails is collagen — a fibrous protein that’s a key building block of connective tissue, giving it strength, elasticity, and structure.
Unfortunately, collagen production in the body starts to slow in our twenties, and that decline accelerates over time, especially after menopause. This collagen loss leads to visible signs of aging.
If the time has come to supplement your collagen production, read on. I’ll share my top three picks for the best collagen supplements on the market — and why they made the list.
As a nutritionist, I believe a holistic approach to health is essential. The three supplements that made it to the top of my list all:
- Contain high-quality ingredients
- Support skin elasticity and hydration
- Nourish hair and nails
- Promote joint comfort and flexibility
- Improves Gut Health – Helps heal the gut lining and balance the microbiome, reducing the inflammation that causes both digestive issues and premature aging.
- Provides Powerful Immune Support – Strengthens your body’s natural defenses while helping you maintain the energy and vitality that keep you looking and feeling younger.
- Promotes Cellular Regeneration – Contains regenerative peptides that work at the cellular level to support repair and renewal throughout the body, addressing aging at its source.
- Enhances Skin – Packed with growth factors shown to reduce the appearance of wrinkles and fine lines while improving skin elasticity and radiance.
- Strengthens Hair & Nails – Bioactive nutrients nourish hair follicles and nail beds from within.
My Picks:
PROS:
- High quality Ingredients
- Simple, no-frills formula
- Easy to find online or in stores
- Great price point
CONS:
- No additional support for gut, immunity, or energy
Verdict: Classic but basic.
PROS:
- Multiple collagen types
- Added ingredients for stress and digestion

CONS:

Final Thoughts
If you’re still using plain collagen, you’re missing out. While all three of these supplements have their place, Colsilk is the only one that goes beyond beauty—supporting your gut, immune system, and skin from within.
In our experience, it’s more than a supplement. It’s a daily ritual you can feel good about.
