Joint pain, stiffness when waking up, knees that creak as soon as you go up the stairs: osteoarthritis ruins the daily lives of millions of people. When treatments struggle to calm everything down, many turn to
food supplements presented as “special joints”.
This self-medication seems reassuring, because it involves plants or yeasts sold without a prescription. However, French health authorities believe that the risks linked to supplements remain underestimated, especially among people suffering fromarthritis who are already taking several long-term medications.
Red yeast rice: an “anti-cholesterol” to avoid in cases of osteoarthritis
Among the most problematic supplements is the
red yeast riceused to lower cholesterol but also, sometimes, for bones and joints. “This is because of its high content of calcium and magnesium, two important nutrients for bone health,” explains Alyssa Pacheco, American dietitian, cited by EatingWell. However, another expert points out that
“Just like statin medications, red yeast rice can cause muscle pain and joint discomfort,” effects already reported to ANSES.
Chaparral and arnica: when “natural” threatens the liver or the heart
Chaparral, a North American shrub sold in “detox” or anti-inflammatory capsules, has already been associated with fulminant hepatitis and emergency liver transplants. “Consumption, even in small quantities, can (trigger) significant health problems, particularly liver toxicity,” explains a specialist, who adds
“No human studies have been conducted to support its use, as the risk far outweighs any potential benefit.”
Arnica is widely used as a gel or cream to soothe painful joints, although some people develop rashes, itching or dry skin. Orally, the danger is much more serious: “Arnica should not be taken orally except on medical advice, as consumption, especially in concentrated amounts, can cause a host of serious side effects, some of which can be fatal” warns the expert.
Devil’s claw, diet: focus on what really helps
Another star of the “joints” sections, the
devil’s claw promises to calm painful outbreaks. “Devil’s claw has a high level of anti-inflammatory properties, which is considered the reason for its potential benefit for those who have osteoarthritis or inflammatory joint problems” recognizes a specialist. Studies remain limited and old, while nausea, stomach upset and interactions with blood pressure or cholesterol medications are well documented.
Healthy lifestyle, the lever to prioritize
To manage osteoarthritis without multiplying the capsules, specialists emphasize a healthy lifestyle. A nutritionist advises, for example: “Foods such as salmon, sardines, berries, oranges, kiwis, broccoli, cauliflower, spinach, nuts, seeds and olive oil are great foods to incorporate into your diet more regularly.” All in addition to regular physical activity and a discussion with the doctor before any new supplement.
