Arjuna’s curcuminoid complex rivals paracetamol in knee osteoarthritis study

06 Apr 2021 --- Arjuna Natural’s proprietary turmeric extract, BCM-95, is as effective as paracetamol in reducing pain and other symptoms of knee osteoarthritis (OA). This is according to a new study, which also demonstrated that the highly bioavailable compound was more effective in reducing inflammation. 

“While previous studies have shown the benefits of BCM-95 for managing the condition, this study is the first to link the anti-arthritic effect of BCM-95 in OA patients to its efficacy in modulating anti-inflammatory markers TNF and CRP,” Dr. Benny Antony, joint managing director of Arjuna, tells NutritionInsight. 

He explains that these inflammation markers are associated with osteoarthritis. BCM-95 has a proven mechanism for not just enhancing bioavailability but also being present in relevant concentrations in the blood for long periods, thus making it available to the cells.

Improved WOMAC scores
Published in Biomed Central BMC, the study included 193 patients diagnosed with knee OA. They were randomized to either receive BCM-95 as a 500 mg two times daily or a 650 mg tablet of paracetamol three times daily for six weeks.

Knee arthritis symptoms of pain, joint stiffness and diminished physical function were evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). 

After six weeks of treatment, responder analysis showed significant improvement in WOMAC scores across all parameters comparable to the paracetamol group, with 18 percent of the BCM-95 group reporting 50 percent improvement and 3 percent of subjects noting 70 percent improvement.

Additionally, CRP levels were reduced by 37.21 percent, and tumor necrosis factor-α (TNF-α) levels were cut by 74.81 percent. Arjuna says the modulation of these anti-inflammatory markers indicates that BCM-95 performed better than paracetamol (not an anti-inflammatory) in this category.

Tackling the mechanisms
Antony was not surprised by the findings as BCM-95 has a long history of use and close to two decades of research. He says it is also the most researched bioavailable turmeric extract with over 70 studies for various indications, including osteoarthritis.

However, he adds the study provides an accurate explanation of the mechanism behind its high efficiency. “This is sure to help countless formulators design more efficient and effective formulations to address their customer’s conditions.”

The researchers believe curcumin’s anti-inflammatory effect is a result of its ability to inhibit pro-inflammatory signals, such as prostaglandins, leukotrienes and cyclooxygenase-2.

Renewing hope for those with OA
According to Arjuna, knee OA is the leading cause of disability and pain among adult and old age populations. An estimated 10 to 15 percent of all adults older than 60 years have some degree of OA, with prevalence higher among women than men.

“This study reaffirms the anti-arthritic effect of BCM-95 and provides renewed hope for millions to improve their quality of life,” notes Nipen Lavingia, brand innovation advisor for Arjuna. 

The investigation was a follow-up to an Arjuna study conducted over a year ago that demonstrated a positive link between its flagship high-bioavailable curcumin formulation and osteoarthritic care. BCM-95 has also been linked with neuroprotective effects. 

A study in August found that the company’s Rhuleave-K botanical blend can help alleviate acute musculoskeletal pain.
