NOW Foods Advanced UC-II® Joint Relief (60 Veg Capsules)
If stiff, aching joints are slowing you down, traditional joint formulas often ask you to swallow two to three enormous horse pills every day—often with mixed results. NOW® Advanced UC-II® Joint Relief offers a fundamentally different, clinically researched approach to joint comfort, flexibility, and daily mobility in just one small capsule per day.
Powered by patented UC-II® undenatured type II collagen, this formula is fortified with synergistic joint allies: Hyaluronic Acid for joint fluid lubrication, Albion™ Boron for bone-cartilage coordination, marine-derived Aquamin® trace minerals, and Vitamin D-3.
Why UC-II® Is Different: The Science of Oral Tolerance
Most collagen products on store shelves are hydrolyzed, meaning the collagen protein has been pre-digested and broken down into small peptides. While hydrolyzed collagen provides general building blocks for skin and connective tissues, it does not communicate directly with your immune system.
UC-II® is undenatured type II collagen. Sourced from chicken sternum cartilage through a patented, low-temperature, non-enzymatic manufacturing process, UC-II preserves the natural 3D triple-helix biological structure of the native collagen molecule.
How It Works in Everyday Terms
Joint stiffness and wear are often driven by an overactive immune response. When joint cartilage sustains minor wear from daily activity or exercise, exposed microscopic cartilage fragments can trigger your body's immune cells to view your own joints as foreign invaders, unleashing inflammatory enzymes that degrade cartilage further.
When you ingest intact, undenatured collagen on an empty stomach, it passes intact into the small intestine, where it contacts specialized immune sensors called Peyer's patches. Through a natural biological mechanism known as oral tolerance, your gut immune system learns to recognize type II collagen as harmless. Specialized regulatory T-cells are activated and migrate directly to your joints, sending signals to quiet down cartilage destruction and support natural joint rebuilding.
Clinical Research: UC-II® vs. Glucosamine & Chondroitin
Peer-reviewed human clinical trials have repeatedly evaluated 40 mg of UC-II® undenatured collagen against standard joint therapies and placebos. The results highlight why this small, 40 mg dose outperforms bulky multi-gram supplements:
✓ Outperforming Glucosamine + Chondroitin in Clinical Trials
In a randomized, double-blind clinical trial published in the International Journal of Medical Sciences, 40 mg daily of UC-II reduced joint discomfort, stiffness, and physical difficulty by more than double the rate of 1,500 mg glucosamine plus 1,200 mg chondroitin over 90 days. A subsequent multicenter trial in Nutrition Journal reaffirmed statistically significant reductions in knee discomfort and significant improvements in physical function.
✓ Enhanced Knee Extension and Flexibility in Active Adults
A clinical trial published in the Journal of the International Society of Sports Nutrition evaluated healthy volunteers who experienced joint discomfort during physical exertion. Supplementation with 40 mg of UC-II resulted in a statistically significant increase in average knee extension range of motion and allowed participants to exercise longer before noticing joint strain.

The "Advanced" Advantage: 4 Synergistic Joint Co-Factors
While standard UC-II products provide only the collagen complex, NOW Foods Advanced UC-II Joint Relief incorporates four critical co-factors that nourish the entire joint capsule—including joint fluid, surrounding bone, and cartilage matrix:
1. Hyaluronic Acid (25 mg)
Acting as your body's natural shock absorber, hyaluronic acid is the chief viscous component of synovial fluid. It cushions joints, reduces internal friction during movement, and helps transport nutrients into avascular cartilage tissue (Oe M, et al. Nutr J. 2016).
2. Boron (Albion™ Bororganic Glycine - 3 mg)
Boron is an essential trace mineral that regulates calcium, magnesium, and phosphorus metabolism. It down-regulates inflammatory markers such as hs-CRP and TNF-alpha while supporting the structural integrity of the subchondral bone beneath joint cartilage (Pizzorno L. Integr Med. 2015).
3. Aquamin® Seaweed Minerals (50 mg)
Derived from the pristine waters of the North Atlantic, Lithothamnium red marine algae provides a bioavailable, multi-mineral matrix of calcium and more than 70 complementary trace elements that support bone density and connective tissue resilience.
4. Vitamin D-3 (1,000 IU / 25 mcg)
Supplying 125% of your Daily Value, Vitamin D-3 ensures proper calcium absorption and supports healthy chondrocyte (cartilage cell) metabolism, helping maintain strong joint structure under physical stress.

Take 1 capsule daily at bedtime on an empty stomach with a glass of water.
Why on an empty stomach? Taking undenatured collagen without food prevents stomach acid and digestive enzymes from breaking down the fragile triple-helix protein structure, allowing it to reach the Peyer's patches in the small intestine intact to trigger oral tolerance.
Safety Information & Warnings:
For adults only. Consult a physician if pregnant or nursing, taking prescription medication, or if you have a medical condition. Keep out of reach of children. Store in a cool, dry place after opening.
Glucosamine vs. UC-II®: Side-by-Side Comparison
For decades, glucosamine and chondroitin were the default recommendation for aging or athletic joints. Here is how modern undenatured collagen compares:
Who Benefits Most from Advanced UC-II® Joint Relief?
Active Adults & Runners
Individuals experiencing temporary joint soreness, stiffness, or reduced range of motion after repetitive high-impact workouts, hiking, or sports.
Aging & Weather-Sensitive Joints
Seniors and mature adults wanting to preserve knee, hip, and finger flexibility without having to swallow difficult multi-pill regimens.
Those with Shellfish Allergies
Anyone seeking joint support who cannot safely take traditional glucosamine derived from crustaceans or marine shellfish.
Frequently Asked Questions (FAQ)
How long does it take for NOW Advanced UC-II Joint Relief to work?
In published human clinical trials, significant improvements in joint comfort and knee extension flexibility were documented within 30 to 90 days of consistent daily use. Because the mechanism relies on training gut immune cells via oral tolerance, consistent daily intake is essential for best results.
Why should I take this supplement at bedtime on an empty stomach?
Undenatured type II collagen relies on its intact, biologically active shape to interact with immune cells (Peyer's patches) in your digestive tract. Taking it at bedtime on an empty stomach minimizes digestive enzymes and stomach acid that could denature the collagen protein, maximizing oral tolerance delivery.
Is NOW Advanced UC-II safe for people with shellfish allergies?
Yes. Unlike traditional glucosamine supplements that are extracted from shellfish shells (crab, shrimp, lobster), UC-II is derived from chicken sternum cartilage, and the formula is completely free from shellfish ingredients.
Can I combine this with hydrolyzed collagen powders or fish oil?
Yes. NOW Advanced UC-II works via an immune-modulating pathway rather than providing bulk amino acids. You can safely take hydrolyzed collagen peptides (types I & III) with meals for hair, skin, and nails, and omega-3 fish oil for systemic inflammation, while keeping your UC-II capsule scheduled at bedtime on an empty stomach.
What role does Boron play in joint health?
Boron (Albion™ Bororganic Glycine) is a vital trace mineral that supports healthy inflammatory response by modulating cytokine markers like hs-CRP and TNF-alpha. It also helps your body retain calcium and magnesium, strengthening the underlying bone architecture that supports your joint cartilage.
