Study shows Nordic Naturals’ triglyceride-form Ultimate Omega/ProOmega is more effective than krill oil, salmon oil and ethyl ester fish oil at increasing blood levels of DHA and EPA.

A recent study published in the July issue of the peer-reviewed journal Lipids in Health and Disease has added new evidence of the power—and value—of Nordic Naturals triglyceride-form best-selling Ultimate Omega®/ProOmega®. Consistently ranked as the number-one-selling omega-3 in the U.S., according to SPINS scan data, the product was shown to be the most effective when compared to other omega-3 products in the marketplace. The goal of the study was to determine which omega-3 product best helps individuals achieve increased blood levels of the omega-3s EPA and DHA.

The randomized clinical trial aimed to compare changes in blood levels of omega-3 fatty acids after consumption of omega-3 supplements when taken according to the manufacturers’ recommended daily dosages. The study was an open-label, randomized, crossover study involving 35 subjects. 

Results showed Nordic Naturals Ultimate Omega/ProOmega in the natural triglyceride form was 382 percent more effective than krill oil, 227 percent more effective than salmon oil, and 47 percent more effective than ethyl ester fish oil.

“This study underscores, once again, the importance of the natural triglyceride form to product efficacy,” said Joar Opheim, CEO and founder of Nordic Naturals. “We’ve always been committed to manufacturing our products in the natural triglyceride form—and science continues to validate that this decision has always been right. Consumers have the right to see the science, and learn why natural fish oil is critical to achieving results.”

Cost comparison of the four products with regard to dosage also generated impressive results. To match the EPA+DHA levels achieved by taking one daily serving of Ultimate Omega/ProOmega at a cost of $0.94, it would require a serving size of krill oil product at a cost of $6.40, salmon oil at a cost of $3.71, and ethyl ester fish oil at a cost of $2.08.

“What this demonstrates is that, at the end of the day, natural triglyceride form products are a better value,” Opheim said. “Responsible dosing is important. When consumers follow manufacturers’ recommended dosing, they are not always getting enough omega-3s. However, they are with Nordic Naturals.” 

Ultimate Omega/ProOmega is available in soft gels and liquid. The product has won several awards and been used for numerous studies by leading research institutions over the last 10 years. Grounded in third-party testing and sound scientific research, Nordic Naturals initiated this comparator study as part of its ongoing commitment to product quality and improved consumer health outcomes.
