Omega-3 Fatty Acids and Vitamin B12 May Ease Menstrual Pain

DENMARK, May 2000 - A double-blind, randomized, placebo-controlled trial suggests that women who regularly experience dysmenorrhea (menstrual pain) can find relief by supplementing their diet with omega-3 fatty acids and vitamin B12. In this trial, 78 Danish women (16 to 39 years of age) received either fish oil (2.5 g/day), fish oil plus vitamin B12 (2.5 g/day), seal oil (5 g/day), or placebo for 3 to 4 months (3 menstrual cycles). Women taking fish oil plus vitamin B12 reported the greatest reduction in intensity of symptoms (e.g., pelvic pain, fatigue, headache) and the most long-lasting relief (up to 3 months after supplementation ended). Eight women reported mild side effects (stomach upset). The researchers posit that supplementation with omega-3 fatty acids (such as fish oil and seal oil) and vitamin B12 may serve as an "alternative treatment to NSAID [non-steroidal anti-inflammatory drugs], such as ibuprofen and aspirin] medication.
