Omega-3’s mixed effects on blood sugar leave diabetes experts divided
Omega-3 fatty acids, commonly found in fish oil supplements, have long been studied for their potential health benefits. Recent research continues to explore their effects on blood sugar levels, though findings remain mixed. Experts now suggest that while omega-3 may not help manage diabetes directly, it could still play a role in heart health for certain patients.
A 2024 study reviewed 30 randomised controlled trials to assess omega-3’s impact on blood sugar regulation. Some trials reported slight reductions in fasting blood sugar, while others found no noticeable effect. The inconsistent results have left researchers divided on whether these supplements meaningfully influence glucose control.
The American Diabetes Association (ADA) currently does not recommend routine omega-3 supplementation for people with diabetes. According to the organisation, evidence supporting its use for blood sugar management remains insufficient. However, the ADA acknowledges that omega-3 may still offer cardiovascular benefits for those with diabetes and a higher risk of heart disease. Despite the uncertainty, medical professionals stress the importance of consulting a doctor before starting omega-3 supplements. This precaution helps avoid potential interactions with other medications and ensures the supplements are suitable for individual health needs.
For now, omega-3 is not advised as a standard treatment for diabetes-related blood sugar control. Yet, it may still be considered for patients with diabetes who face an increased risk of cardiovascular issues. Anyone thinking about taking these supplements should first seek medical advice to weigh the benefits and risks.
