The science behind Vitalyra

What hyaluronic acid does inside your joints, why it runs low as we age, and what research on taking it by mouth actually shows.

1. Your joints run on fluid

Every moving joint, from your knees and hips to your shoulders and fingers, sits inside a capsule filled with synovial fluid. It's what lets the ends of your bones glide past each other thousands of times a day without grinding. What makes that fluid thick, slippery and cushioning is one molecule: hyaluronic acid (HA). HA holds many times its own weight in water, which is why healthy joint fluid has the texture of egg white rather than plain water.

2. What changes as we get older

Research on aging and arthritic knees shows that HA in the joint fluid tends to drop, and what's left breaks down into smaller, thinner pieces. Less HA means thinner fluid. Thinner fluid means less cushion and more friction. That's the pattern so many people over 50 recognize: stiff when you first stand up, a click or grind on the stairs, and joints that loosen up only after you've been moving for a while.

3. What the research says about taking HA by mouth

In a double-blind, placebo-controlled trial, adults who took 200 mg of hyaluronic acid daily improved more than the placebo group on knee quality-of-life scores (Tashiro et al., ScientificWorldJournal, 2012).

When researchers gave labeled hyaluronic acid by mouth, it was absorbed and showed up in joints and connective tissue (Balogh et al., J Agric Food Chem, 2008; an animal study).

In the largest U.S. study, 1,583 adults took glucosamine, chondroitin, both or a placebo for 24 weeks. Overall, none beat the placebo for knee pain (Clegg et al., N Engl J Med, 2006).
