Krill Oil May Help Relieve Knee Discomfort

Krill oil is a rich source of omega-3’s and also contains antioxidants and vitamin A. A new study suggests that daily supplementation with krill oil may help relieve knee discomfort. 

Participants in the study included 235 adults with mild to moderate knee discomfort and low levels of omega-3’s in their diet. They were given 4 grams of krill oil (containing 880 mg of omega-3 fatty acids and 450 mcg of astaxanthin) or  a placebo daily for 6 months. 

Scores for knee discomfort, knee stiffness, and physical function were assessed at baseline, 3 months, and 6 months using the Western Ontario and McMaster Universities Arthritic Index (WOMAC). Participants’ omega-3 index levels were measured at baseline, 3 months, and 6 months. 

Participants in the krill oil group saw significant improvements in knee discomfort compared to the placebo group. They also saw significant improvements in knee stiffness and physical function. 

In addition, the omega -3 index level increased from 6% to 8.9% in the krill oil group. In comparison, the omega-3 index level in the placebo group decreased from 5.5% to 5.4%. 

The study was conducted by researchers from the University of Adelaide. It was published online ahead of print on July 26, 2022 in The American Journal of Clinical Nutrition.

Collagen and Boswellia serrata were found to help knee discomfort in a previous study.
