As the main structural protein of connective tissue, collagen is essential for proper joint function, and may provide specific benefits such as:

  • Promoting overall joint health. Collagen plays a key role in the growth and strengthening of joints, tendons, and cartilage.  
  • Improving joint disorders. Collagen may reduce inflammation and other markers of joint disorders.

Overview

As the main structural protein in connective tissue, collagen is the most abundant type of protein found in humans and other mammals, accounting for 25-35% of total body protein content. Collagen constitutes nearly 2% of muscle tissue and is also integrated into bone, tendon (including skin and ligaments), cartilage, cornea, and even blood vessels.

Collagen has been categorized into over 16 different types, although about 90% of collagen in the body is either type I, II, or III. Among its 3 main types, collagen type II is the one most responsible for joint development and maintenance.

Contemporary science has utilized collagen derivatives for culinary, beauty, and medicinal reasons. In terms of joint health, collagen is popularly used in joint supplements to reduce pain and inflammation, particularly in the context of disorders such as arthritis.

How Collagen Might Help With Joint Health

Collagen supplementation might support joint health in a variety of ways:

Osteoblast differentiation

Collagen seems to aid cellular growth and regeneration in and around joints by differentiating bone cells, or osteoblasts.12

Stabilizing serum antibodies

By reducing the quantity of antibodies against itself, collagen supplements may reduce inflammation and subsequent pain.3

Enhancing bone density

Like other proteins, hydrolyzed collagen supplementation is shown to increase bone density4, bone mass, and bone strength, which may improve overall joint stability.5

Reducing inflammation and dysfunctional immune responses

Type II collagen in particular has adifferent course of action when it comes to the destructive consequences of elevated T-cell levels and inflammatory markers in the autoimmune condition rheumatoid arthritis (RA). Oral ingestion of low doses of collagen II seems to enable immune cells to tolerate collagen and gradually reduce (or even prevent) adverse autoimmune responses. Consumption of proper doses of UC-II seems to:

  • Prevent the body from destroying cells near joints, known as immunoreactivity6
  • Boost production of antibodies, specifically IgG2A and IgG17
  • Reduce inflammation by increasing the release of the cytokine IL-10, which suppresses the destructive effects of IL-178

Collagen Benefits & Uses for Joint Health

Collagen, specifically collagen II, may be a potent supplement for supporting overall joint health. It seems especially effective when it comes to recovering from joint pain and deterioration due to arthritis and similar joint complications. It works especially well in combination with other joint supplement ingredients.

Among the myriad of joint benefits it might impart, collagen looks to have concrete backing when it comes to pain reduction (including morning stiffness, stiffness following periods of rest, pain that worsens with use of the affected joint) and improved joint range of motion and function.

Hydrolyzed vs Undenatured Collagen

The two primary collagen supplements for joint health are hydrolyzed collagen and undenatured collagen. Their preparation differs so much that they can almost be considered two distinct supplements.

Hydrolyzed collagen yields moderate improvements in joint comfort and is praised for its high bioavailability. It is regularly taken at doses of 3 to 6 grams per day.

Undenatured collagen is most commonly offered as glycosylated undenatured type II collagen (UC-II) to people with joint pain, and more specifically for those battling rheumatoid arthritis or osteoarthritis. Dosage is much lower at an average 0.1 mg, although amounts as low as 20 mcg and up to 1 mg have been shown to be effective.

Research

Animal Research

Animal research suggests that collagen may improve joint health by:

  • Diminishing joint pain and immobility. Dogs receiving either 1 or 10 mg of UC-II showed significant reductions in pain during limb movement and lameness after exertion, as well as increased physical activity.9 Significant pain reductions were also noted when UC-II was taken in combination with glucosamine and chondroitin.10
  • Improving arthritic conditions. Horses receiving either 320, 480, or 640 mg of UC-II were observed to have improved status of overall arthritic pain.11

Human Research

Collectively, clinical studies demonstrate collagen’s capacity to reduce joint pain and swelling, improve joint mobility, and delay the onset of joint discomfort.

Undenatured type II collagen (0.1 – 1 mg) may reduce joint pain and swelling in seniors with rheumatoid arthritis

In this randomized, placebo-controlled, double-blind investigation, 60 elderly patients with severe, active rheumatoid arthritis were daily given chicken type II undenatured collagen at 0.1 mg for 1 month and then 1 mg for the following 2 months. The supplementation resulted in reduced joint pain and stiffness.

  • The study concluded that “a decrease in the number of swollen joints and tender joints occurred in subjects fed chicken type II collagen for 3 months but not in those that received a placebo. Four patients in the collagen group had complete remission of the disease.”12

Undenatured type II collagen (40 mg) may improve knee extension and range of motion, as well as delay the onset of joint discomfort

In this randomized, double-blind, placebo-controlled investigation, 55 adults with mild joint discomfort were given either a placebo or 40 mg of undenatured type II collagen (UC-II) derived from chicken sternum every day for a period of 120 days. Those in the UC-II group showed statistically significant improvement in average knee extension and longer exercising stints before feeling any initial joint discomfort, 2.8 ± 0.5 min, compared to baseline, 1.4 ± 0.2 min.

  • The study concluded that “daily supplementation with 40 mg of UC-II was well tolerated and led to improved knee joint extension in healthy subjects. UC-II also demonstrated the potential to lengthen the period of pain free strenuous exertion and alleviate the joint pain that occasionally arises from such activities.”13

Undenatured type II collagen (40 mg) may enhance joint functioning and reduce pain in the completion of daily activities by adults with osteoarthritis

In this cohort study, 52 adults with osteoarthritis were given either UC-II, one 20 mg capsule in the morning and another in the evening, or a combination of glucosamine and chondroitin (G+C) for 90 days. UC-II treatment showed significantly better improvements than the G+C treatment in several measures of osteoarthritis, including pain and overall joint function.

  • The study concluded that “UC-II treated subjects showed significant enhancement in daily activities suggesting an improvement in their quality of life.”14

Hydrolyzed collagen (10 g) may improve joint comfort in adults with primary osteoarthritis

In this randomized, double-blind, placebo-controlled study, 250 adults with primary osteoarthritis of the knee were given 10 grams of collagen hydrolysate (CH) daily for 6 months resulting in significant improvements in knee comfort.

  • The study concluded that “there was a significant improvement in knee joint comfort as assessed by visual analogue scales to assess pain and the Womac pain subscale. Subjects with the greatest joint deterioration, and with least intake of meat protein in their habitual diets, benefited most.”15

Undenatured type II collagen (20 mcg) may reduce joint pain and swelling in adults with rheumatoid arthritis

In this randomized, placebo-controlled, double-blind investigation, 247 adults with rheumatoid arthritis were given placebo or one of four doses of undenatured type II collagen (20, 100, 500, 2,500 mcg) for 24 weeks. Out of all groups, 20 mcg showed the highest response rate and the most improvement in the three sets of criteria: the American College of Rheumatology criteria for improvement in RA, the Paulus criteria, and a requirement for > or = 30% reduction in swollen and tender joint counts.

  • The study concluded that “the efficacy seen with the lowest [collagen] dosage is consistent with the findings of animal studies and with known mechanisms of oral tolerance in which lower doses of orally administered autoantigens preferentially induce disease-suppressing regulatory cells.”16
Chicken-derived collagen seems to be most effective. Thus far, most successful clinical studies have utilized chicken collagen extracts, whereas other sources of collagen have seen little successful research .17

Dosage for Joint Health

For joint health, collagen may be taken as:

  1. Hydrolyzed collagen
    • Capsules, 1 – 10 grams
    • Powder, stirred into a drink, 6.6 grams per scoop
  2. Undenatured type II collagen
    • Tablets, 20 mcg – 40 mg

Supplements in Review Says

  • Collagen 3 – 6 grams for joint health.

We recommend collagen for promoting overall joint health. Collagen II supplements are one of the better candidates for reducing joint pain, discomfort, and swelling.

There are 2 viable types of collagen supplementation. Proper dosing depends heavily on the intention of supplementation. Undenatured type II collagen at about 40 mg seems ideal for combating joint pain, swelling, and deterioration. Hydrolyzed collagen from 3-10 grams seems better suited for regular use to improve joint health in otherwise healthy conditions.

    Can you take both? Together or Separately I have been taking type ii 40mg Now the powder seems very popular but I thought it wasn’t efficatious to mix the 3 types in 1 supplement? Should I switch to the hydrolysate powder -stick with the type ii which also contains 5 mg of boron & 3.3 HA- or do both? I’m senior female-very active -Osteoarthritis not Rheumatoid/previous hip replacement

    Hi Natalie, generally speaking type 2 is best for your joints because type 1 and type 3 collagen are found mostly in the skin, hair, and nails. This is also the reason why hydrolysate powders mixing all 3 (well, actually 5) are so popular – people take them to support joints, skin, nails, and hair all at once. Isolated type 2 is probably better for your joints, but if you want all of the benefits you can consider switching to hydrolysate.
