Kolagen pro klouby: co pomáhá, jak ho vybrat a kdy začít

When you feel stiffness in your knees or pain when climbing stairs, it’s not just aging—it’s your kolagen pro klouby, přirozený protein, který tvoří základ chrupavky, šlach a vazů. Also known as kolagen typu II, it’s the main building block your joints rely on to stay smooth and shock-absorbing. As you get older, or after injury or heavy training, your body doesn’t make enough of it—and that’s when the pain starts.

Not all kolagen is the same. For joints, kolagen typu I, nejčastější typ v těle, který podporuje i vazovou strukturu is often used in supplements, but for cartilage repair, kolagen typu II, specifický pro kloubní chrupavku a často používaný v injekcích is what science points to. Injections are used when the damage is advanced—think osteoarthritis, chronic pain, or failed conservative treatment. They work by delivering purified collagen directly into the joint, helping rebuild tissue and reduce inflammation. But for most people, oral supplements with hydrolyzed collagen and vitamin C are enough to slow down degradation and improve mobility over time.

Don’t expect miracles in a week. Studies show you need at least 8–12 weeks of daily use before noticing less stiffness and better movement. Look for products with 10 grams of collagen peptides per serving, paired with vitamin C—your body needs it to turn collagen into usable tissue. Avoid cheap blends full of fillers. If you’re active, lifting weights, or just walking a lot, your joints are under stress—and kolagen isn’t a luxury, it’s maintenance.

You’ll find real stories in the posts below: from people who tried injections and saw results after months, to those who switched to daily powder and regained comfort in their knees. Some tried it after knee surgery, others because their ankles started creaking in the morning. You’ll learn which brands actually deliver, what to avoid, and how to combine kolagen with movement and simple nutrition to get the most out of it. No hype. Just what works.
