    Saffron may positively influence cardiovascular and metabolic health by potentially improving lipid profiles and glycemic control and possibly reducing blood pressure; however, the research is inconsistent and varies across different populations and formulations. Notably, its benefits may not be significant for people with elevated lipid levels or type 2 diabetes.

    Saffron may have a beneficial effect on various aspects of cardiovascular health and metabolic health. Still, the research is mixed, and studies have included a wide range of patient populations, doses, and formulations (e.g., saffron extract, whole saffron powder, isolated crocin), which makes it difficult to draw any clear conclusions.

    Some evidence suggests that saffron can affect lipid profiles, including reductions in triglycerides, total cholesterol, and low-density lipoprotein (LDL) cholesterol. However, this effect may not be observed when it matters most: in people with elevated lipid levels or type 2 diabetes.[1][2]

    Saffron may improve glycemic control, with some research finding reductions in both hemoglobin A1c (HbA1c) and fasting glucose, including in people with type 2 diabetes.[1][2]

    Saffron might reduce blood pressure, but most research that finds a reduction in systolic blood pressure has found no change in diastolic blood pressure.[1][2]
