A major new umbrella review was recently published in the Aesthetic Surgery Journal Open Forum (January 2026). [1]
This wasn’t a small study.
The researchers analyzed 16 systematic reviews covering 113 randomized controlled trials and nearly 8,000 participants.
The findings were exactly what I’ve experienced firsthand.
- Skin elasticity: Significant improvement, with effect sizes researchers called among the strongest in the review.
- Skin hydration: Consistent improvement across thousands of participants.
- Joint pain: Real reductions in pain across 2,600+ people. Not a placebo effect.
- Fat-free mass: Meaningful increase in lean tissue with consistent supplementation.
- Maximal strength: Statistically significant gains across 11 trials.
The researchers also found the benefits are duration-dependent. Meaning the longer you stay consistent, the better the results.
The strongest signals came at 8 to 12 weeks of daily use.
Since the modern diet just doesn’t deliver collagen…
Your joints are working harder, your skin is getting less structural support, and your tendons and ligaments are under-recovered.
And you don’t even know it because there’s no dramatic symptom. It’s just a slow erosion of how good you feel and how well your body holds up.
This is why I think supplementing collagen protein is critical.
Why Kino Collagen Specifically
Kino Collagen is grass-fed and loaded with glycine, the key amino acid your body uses to build and repair collagen tissue.
Glycine also plays a role in sleep quality and gut health.
It also contains Hyaluronic Acid, which most collagen supplements skip entirely.
Collagen gives your skin its structure. Hyaluronic Acid keeps everything hydrated from the inside out.
You need both, and most collagen supplements only give you one.
Your joints, skin, and connective tissue all depend on collagen. This is the simplest way to make sure they’re getting it.
