Joint pain can be bothersome and may impact the quality of life of those affected. Most often due to arthritis, it can be quite challenging to alleviate. Among the possible options, the use of treatments containing collagen is sometimes mentioned. Do these products truly offer effective relief?

Joint Pain: Effects of Collagen?
Naturally synthesized by the body, collagen is particularly found in joints and bones where it ensures cohesion, elasticity, and tissue regeneration. Collagen fibers act as a cushion to reduce shocks between bones and pressures. Additionally, collagen aids in the healing of tissues in case of damaged joints. This protein constitutes approximately 67% of the dry weight of cartilage. However, the efficiency of collagen production decreases over time. Certain sports or professional activities can also contribute to the premature wear of joint collagen, which can increase the risks of osteoarthritis or, more generally, joint pain.
To prevent or mitigate them, some people embark on a collagen regimen. Most dietary supplements available on the market are based on collagen type II native or hydrolyzed collagen. Several studies have been conducted on the effects of such supplementation. The majority have reported positive results in terms of pain relief and improvement in joint function. Moreover, changes in cartilage degradation have been detected. The results of a few studies are presented in the table below.
Study | Type of Collagen | Clinical Condition | Duration of the Study | Daily Dosage | Results |
---|---|---|---|---|---|
ATLAS & al. (2016) | Native Collagen | Osteoarthritis | 3 months | 40 mg | Significant reduction in discomfort |
LANE & al. (2016) | Native Collagen | Osteoarthritis | 6 months | 40 mg | Significant reduction in discomfort |
BOFF & al. (2020) | Native Collagen | Osteoarthritis | 3 months | 40 mg | No difference compared to the placebo |
SHAMIE & al. (2013) | Native Collagen | Joint pain without arthritis | 4 months | 40 mg | Significant reduction in discomfort |
JUTURU & al. (2022) | Native Collagen | Joint pain without arthritis | 6 months | 40 mg | Significant reduction in discomfort |
FLECHSENHAR & al. (2011) | Hydrolyzed Collagen | Osteoarthritis | 6 months | 10 g | Significant reduction in discomfort |
BERNARDO & al. (2012) | Hydrolyzed Collagen | Osteoarthritis | 6 months | 1.2 g | Significant reduction in discomfort |
VENKATESWARATHIRUKUMARA & al. (2014) | Hydrolyzed Collagen | Osteoarthritis | 3 months | 10 g | Significant reduction in discomfort |
ALBERT & al. (2008) | Hydrolyzed Collagen | Joint pain without arthritis | 6 months | 10 g | Significant reduction in discomfort |
HOPMAN & al. (2020) | Hydrolyzed Collagen | Joint pain without arthritis | 3 months | 10 g | No difference compared to the placebo |
However, there is a significant heterogeneity in the design and implementation of studies, often with very small participant samples. Furthermore, the effects of collagen treatment are rarely compared to those of a placebo or, when they are, the effects of placebos are not always considered. Additionally, studies do not indicate whether the effects of supplementation have lasted over time and/or if the treatment was continued or discontinued.
Finally, one might question the effectiveness of thebody's absorption of collagen, criticized by some researchers due to the significant molecular weight of collagen (300 kDa). Indeed, once ingested, it is broken down into amino acids in order to cross the intestinal barrier. These amino acids can then be used by the body to rebuild proteins, but it is not guaranteed that they will specifically form collagen. This also applies to collagen hydrolysate, which corresponds to collagen peptides. As a reminder, peptides are short chains of amino acids, not performing exactly the same functions as native proteins.
It is prudent to be cautious about the potential effects of collagen treatments on the joints.
