Results of a new study published in the journal Biomed Central BMC showed turmeric extract was as effective as paracetamol in reducing pain and other symptoms of knee osteoarthritis (OA). The study demonstrated the bioavailable compound was more effective in reducing inflammation.

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.

In the randomized, double-blinded crossover study, 11 well-trained male athletes underwent three exhaustive exercise tests after a week of supplementation with a tomato powder, then a lycopene supplement, and then a placebo. Three blood samples (baseline, post-ingestion, and post-exercise) were taken for each of the supplements used, in order to evaluate total antioxidant capacity and variables of lipid peroxidation, such as malondialdehyde (MDA) and 8-isoprostane.

Knee OA is the leading cause of disability and pain among adult and old age populations. An estimated 10 to 15% of all adults older than 60 years have some degree of OA, with prevalence higher among women than men.
