Recent Study Reinforces the Benefits of Omega-3 for Weight Control

Pronova Biocare Continues to Emphasize the Importance of Omega-3s

LYSAKER, Norway, January 24, 2005 -- A recent article published in Lipids 2004 reviewed effects of omega-3s and weight control. The study reaffirms Pronova Biocare's (the world leading supplier of Omega-3 fatty acids and makers of EPAX® Omega-3 EPA/DHA concentrates) research concluding the importance of omega-3s for general health and weight control.

"It is well established that a diet rich in seafood prevents weight gain but the mechanisms responsible for this effect has not been known," stated Morten Bryhn, M.D., Ph.D., director of research and development for Pronova Biocare, makers of EPAX® Omega-3 EPA/DHA. "This article presents effects on weight reduction in obesity prone animals using different omega-3 concentrates containing EPA (eicosapentaenoic acid) or DHA (docosahexaenoic acid). These animals behave very much like humans in the way that overfeeding leads to severe obesity."

Data from the study clearly demonstrated that the omega-3 concentrate rich in DHA (EPAX 1050 TG) increased oxidation of fat by activating genes that breaks down fat in the mitochondriae and peroxisomes. These effects not only showed weight reduction but they also showed weight gain prevention in animals given free access to food. Additionally, the omega-3 concentrate not only intensified breakdown of fat but also reduced the number of fat cells, especially in the abdominal region. The effects were augmented in animals on a concomitant 10% calorie reduction regimen.

This regimen has also been tested in a pilot study, presented at the North American Association for Study of Obesity (NAASO) Annual Meeting, November 2004, including 20 women with severe obesity (Body Mass Index, BMI, more that 40). The women were already on a very low calorie diet. The group given the omega-3 concentrate reduced their weight by 20% more than the group given placebo after only three weeks of treatment. BMI was reduced by as much as 15%. The effects were highly impressive because of the short treatment period. A new, larger study in obese women is ongoing testing EPAX 1050 TG against placebo.

"Being overweight is not only a problem of too much food and too little exercise but also a problem of bombarding genes with signals leading to fat accumulation. A diet rich in red meat and vegetable oils increases accumulation of fat in fat tissue because of a chronic disarray of genes responsible for handling fatty acids and carbohydrates," stated Dr. Bryhn. "The number of fat cells increases and turnover of carbohydrates into fat is facilitated. The net result is being overweight which leads to obesity that is difficult to curb by calorie reduction and exercise only. Genes are constantly programmed to a situation of starvation and they need to be reprogrammed. Omega-3 fatty acids from seafood seem to do exactly that."

According to Dr. Bryhn, the process of reprogramming genes is slow so no drastic effect is to be expected by taking EPAX 1050 TG. Weight control should be a combination of: reduced intake of red meat, saturated fat and foods containing vegetable oils and carbohydrates, regular exercise and increased intake of omega-3 fatty acids high in DHA, like EPAX 1050 TG.

The health benefits of marine omega-3 fatty acids are increasingly being accepted worldwide. The scientific evidence continues to mount, representing an opportunity for the treatment and prevention of common diseases. The American Heart Association and the World Health Organization both support the addition of omega-3 fatty acids to diets citing their importance in maintaining good health.

At Pronova Biocare, each and every production run of omega-3 carries full quality control documentation to ensure that the highest purity and quality standards are maintained. Chemical analyses take place at every crucial stage and the most stringent, hygienic conditions are applied throughout Pronova Biocare operations. EPAX products are produced in Pronova's GMP state-of-the-art facilities to meet the highest possible quality standards.
The products also comply with the CRN voluntary monograph.

Pronova Biocare, headquartered in Lysaker, Norway, has two GMP approved production facilities: one located in Sandefjord that is qualified by the US Food and Drug Agency for producing omega-3 pharmaceuticals and the second located in Alesund. Pronova Biocare offers Omega-3 EPA/DHA oils in the B2B segment under the brand name EPAX. EPAX is available in a wide range of top quality formulas with different EPA/DHA ratios.
