NOW Supplements UC-II Type II Collagen is a specialized joint health supplement that uses undenatured type II collagen from chicken sternum cartilage. This form of collagen is the primary structural protein in cartilage, responsible for its tensile strength and toughness. It is designed for individuals seeking to maintain joint flexibility and comfort, particularly those with active lifestyles or age-related joint concerns.
The standout feature is the UC-II ingredient, which is a unique, patented form of undenatured type II collagen. Unlike hydrolyzed collagen, UC-II works with the immune system to support healthy joints by modulating the body's response to joint stress.

Buying Guide
Undenatured vs. Hydrolyzed Collagen
Not all collagen supplements work the same way. Undenatured type 2 collagen (UC-II) retains its native triple helix structure, which allows it to interact with the immune system in the gut and promote joint comfort. Hydrolyzed collagen, on the other hand, is broken down into peptides for skin and general connective tissue. For targeted joint support, UC-II is the preferred choice. Look for products that specify “undenatured” and use patented ingredients like UC-II.
Dosage and Potency
Clinical studies show that just 40 mg of undenatured type 2 collagen per day can improve joint function and reduce discomfort. All three products in our comparison deliver that exact dose per serving. Some formulations add complementary ingredients like hyaluronic acid or shea nut oil to enhance absorption. Consider whether you prefer a straightforward capsule or a bioenhanced softgel.
Quality and Manufacturing Standards
Third party certification matters for purity and potency. NOW Supplements holds GMP certification and is Non-GMO, soy free, and gluten free. Naturalis also follows cGMP standards and is manufactured in a California facility. Always choose supplements from reputable brands that disclose their sourcing and verification processes. For more on supplement quality, visit our Joint Support category page.
Form and Convenience
Capsules versus softgels: each has pros. NOW offers veg capsules (60 or 120 count) that are easy to swallow and free from common allergens. Naturalis uses liquid softgels with nano emulsification for potentially better absorption. Consider your daily routine and any dietary restrictions. A 60 capsule bottle lasts two months at one capsule per day, while the 120 count provides a four month supply.
Final Thoughts
For most people seeking reliable joint support, NOW Supplements, UC-II Type II Collagen offers a well proven, affordable option with a generous supply of 120 veg capsules. If you prefer a bioenhanced formula with added hyaluronic acid for extra joint cushioning, the Naturalis UC-II 40 mg 60 Softgels is an excellent choice. Both deliver the clinically studied 40 mg dose of undenatured type 2 collagen. Choose the one that fits your lifestyle and budget, and start moving more comfortably.
Frequently Asked Questions
What is the difference between undenatured type 2 collagen and regular collagen?
Undenatured collagen retains its natural structure, which helps it interact with immune cells in the gut to support joint health. Hydrolyzed collagen is broken down into smaller peptides and is used more for skin and overall connective tissue. For joint specific benefits, undenatured type 2 collagen is the preferred option.
How long does it take for UC-II to work?
Many users notice improvements in joint comfort within 30 to 60 days of daily use. Consistency is key, as the supplement works gradually with your immune system. Pair it with a healthy lifestyle and regular movement for best results.
Can I take undenatured type 2 collagen with other supplements?
Yes, UC-II is generally safe to combine with other joint supplements like glucosamine or turmeric. However, always consult your healthcare provider before adding new supplements to your routine. For more on natural support, read our guide on how to support prostate health naturally.
Are there any side effects?
Undenatured type 2 collagen is well tolerated by most people. Some may experience mild digestive upset initially. Start with one capsule per day and drink plenty of water. If you have a chicken allergy, avoid products derived from chicken sternum cartilage.
