Led by Shuba Singhal, PhD, this randomized, controlled clinical study was conducted at the Department of Orthopedics of Lok Nayak Jai Prakash Hospital/Maulana Azad Medical College, New Delhi. For the study, 193 patients diagnosed with osteoarthritis of the knee were randomized to receive either turmeric extract (BCM-95) as a 500 mg capsule two times daily, or a 650 mg tablet of paracetamol three times daily for six weeks.

With the brevity of the study duration, the authors did hypothesize, however, that a longer-term supplementation regimen of lycopene could result in stronger antioxidant benefits for the isolated nutrient, in accordance with other studies that were carried out over a period of several weeks. Nonetheless, whole tomato contains chemical compounds that can enhance beneficial outcomes in synergy compared to a single compound, the authors said.
