Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Vitamin C, also known as ascorbic acid, has some scientific basis for its use in supporting joint health, though the evidence is moderate and not robust. Vitamin C is essential for the synthesis of collagen, a key structural protein found in connective tissues, including cartilage, tendons, and ligaments that form and support the joints. Deficiency of vitamin C results in impaired collagen formation, leading to joint pain and swelling as seen in scurvy.
Several laboratory and animal studies have demonstrated that vitamin C can support collagen production and reduce oxidative stress in joint tissues. Some observational studies in humans have suggested that higher dietary intake of vitamin C is associated with a lower risk of developing osteoarthritis and may slow its progression. For example, a study published in Arthritis & Rheumatism (2004) found that participants with higher vitamin C intake had a reduced risk of knee osteoarthritis progression.
However, randomized controlled trials on vitamin C supplementation for joint health in humans are limited, and the results have been inconsistent. There is insufficient evidence to confirm that supplementation with vitamin C alone provides significant therapeutic benefit for joint disorders such as osteoarthritis or rheumatoid arthritis in otherwise healthy individuals. Thus, while there is a scientific rationale rooted in vitamin C’s role in collagen synthesis, the overall evidence supporting its supplemental use specifically for joint health is moderate at best.
