Omega-3s and girls’ metabolism
by Newsletter Editor
In this study, 25 obese boys and girls, aged 14 to 17, took a placebo or a daily supplement containing 930 mg EPA (eicosapentaenoic acid), 290 mg DHA (docosahexaenoic acid), 100 mg GLA (gamma-linolenic acid), and 19.8 IU vitamin E for three months. After a six-week rest phase, participants alternated placebo and supplement for another three months.
While there were no changes for placebo, or blood sugar benefits for boys, girls taking omega-3s had 17 percent greater insulin sensitivity, a 34 percent increase in insulin levels during a glucose tolerance test, and 39 percent better glucose tolerance.
Circulating levels of EPA and DHA increased significantly for both boys and girls, and both had higher tissue and skeletal muscle levels of omega-3s and lower tissue levels of omega-6s, which doctors said raised the chances of maintaining healthy metabolic function in the future.
