Krill Oil and Metformin in Women With PCOS and Metabolically Unhealthy Obesity

17. maj 2026 opdateret af: Murat Açık, Firat University

Effects of Krill Oil and Metformin on Cardiometabolic, Adipokine, Hormonal, and Fatty Acid Profiles in Women With Polycystic Ovary Syndrome and Metabolically Unhealthy Obesity: An Open-Label, Randomized, Parallel-Group Pilot Trial

This open-label, randomized, parallel-group pilot trial investigated the effects of krill oil, metformin, and their combination on adipokine profiles, cardiometabolic risk markers, and serum fatty acid composition in women with polycystic ovary syndrome (PCOS) and metabolically unhealthy obesity (MUO). Eligible women aged 19-40 years with PCOS according to Rotterdam criteria and MUO based on combined NCEP ATP-III/IDF criteria were allocated to three 8-week interventions: continuation of standard metformin therapy (MET), krill oil supplementation alone (KO), or metformin plus krill oil (METKO). Metformin users were stratified and randomized 1:1 to MET or METKO, while metformin-naive participants were assigned to KO. Krill oil (Superba Boost, Aker BioMarine) was administered at 2,000 mg/day (approximately 400 mg EPA and 240 mg DHA) and metformin at 1,000 mg/day. Primary outcomes were changes in serum adiponectin and neuregulin-4 (NRG-4) measured by ELISA. Secondary outcomes included anthropometric indices, fasting glucose, insulin, HOMA-IR, lipid profile, reproductive hormones, and detailed serum fatty acid profiling by GC-MS, as well as Mediterranean Diet Adherence Screener (MEDAS) scores. The trial aimed to provide preliminary evidence on whether adding krill oil to metformin therapy offers broader metabolic benefits than either intervention alone in women with PCOS and MUO.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Metformin Group (MET)
Participants received Metformin Hydrochloride 1000 mg/day (single daily oral dose) for 8 weeks. No dietary supplement was added in this group.
Medicin: Metformin Hydrochloride 1000 MG
Metformin Hydrochloride 1000 mg/day (single daily oral dose) for 8 weeks. Metformin is a biguanide antidiabetic drug that improves insulin sensitivity and reduces hepatic glucose production. Used as standard treatment for PCOS-related insulin resistance and metabolic dysfunction.
Eksperimentel: Krill Oil Group (KO)
Participants received Krill Oil 2 g/day (1 g twice daily, orally) for 8 weeks. No pharmaceutical agent was administered in this group.
Kosttilskud: Krill Oil
Krill Oil 2 g/day (1 g twice daily, oral administration) for 8 weeks. Krill oil is a marine-derived omega-3 fatty acid supplement rich in EPA, DHA, and phospholipids with antioxidant astaxanthin. It has anti-inflammatory, lipid-modulating, and insulin-sensitizing properties relevant to PCOS and metabolic obesity management.
Eksperimentel: Metformin + Krill Oil Group (METKO)
Participants received Metformin Hydrochloride 1000 mg/day (single daily oral dose) combined with Krill Oil 2 g/day (1 g twice daily, orally) for 8 weeks.
Medicin: Metformin Hydrochloride 1000 MG
Metformin Hydrochloride 1000 mg/day (single daily oral dose) for 8 weeks. Metformin is a biguanide antidiabetic drug that improves insulin sensitivity and reduces hepatic glucose production. Used as standard treatment for PCOS-related insulin resistance and metabolic dysfunction.
Kosttilskud: Krill Oil
Krill Oil 2 g/day (1 g twice daily, oral administration) for 8 weeks. Krill oil is a marine-derived omega-3 fatty acid supplement rich in EPA, DHA, and phospholipids with antioxidant astaxanthin. It has anti-inflammatory, lipid-modulating, and insulin-sensitizing properties relevant to PCOS and metabolic obesity management.
Ingen indgriben: Control Group
Participants received no intervention during the 8-week study period. They continued their habitual lifestyle without any dietary supplementation or pharmaceutical treatment.
