Taking a specific type of fish oil daily for three months may help lower insulin levels in obese Mexican women between 25 and 45, and the benefit might last even after they stop taking it — without needing to lose weight.

We analyzed one assertion on omega-3 supplementation and insulin resistance in obese Mexican women, and it supports the idea that taking a specific type of fish oil daily for three months may help lower insulin levels in this group, aged 25 to 45. The effect was seen even when no weight loss occurred, and it appeared to last after supplementation stopped [1]. What we’ve found so far is limited to this single assertion, which does not include details about the dose, type of omega-3, or how insulin was measured. There are no studies in our review that contradict this finding, but we also don’t have data from larger trials, different populations, or long-term follow-up beyond the three-month period. The evidence we’ve reviewed leans toward a possible benefit, but we cannot say whether this applies to all obese Mexican women or if the effect is strong, moderate, or small. We don’t know if other types of omega-3 supplements would have the same result, or if the benefit holds for women outside this age range. The assertion mentions no side effects, no comparison to placebo, and no information about diet or activity changes during the study. Without more data, we can’t determine how reliable or repeatable this outcome is. For now, if you’re an obese Mexican woman between 25 and 45 and considering omega-3s to help manage insulin levels, this one report suggests it might be worth exploring — but it’s not a guaranteed or proven solution. Always talk with a healthcare provider before starting any new supplement, especially if you have other health conditions.
