Saffron and Weight Management: What the Research Studied

Saffron is a culinary spice valued for its aroma, flavor and golden color. Claims that saffron causes weight loss need a separate look at the exact product, dose, population and duration studied.

What one randomized trial tested

A 2010 randomized, double-blind, placebo-controlled trial enrolled 60 healthy, mildly overweight women for eight weeks. Participants took capsules containing 176.5 mg per day of Satiereal, a named proprietary saffron-stigma extract, or placebo. The researchers reported fewer self-recorded snacking episodes and a greater reduction in body weight in the extract group (PubMed record and abstract).

What the trial does not establish

  • It did not test culinary saffron threads or powder added to food.
  • It did not test a Mehr Saffron product.
  • It was small, lasted eight weeks and enrolled only healthy, mildly overweight women.
  • Its findings do not establish long-term effectiveness, results in other populations or a mechanism involving serotonin.

The study is evidence about that proprietary extract under those trial conditions. It is not evidence that cooking with saffron suppresses appetite, treats emotional eating or produces weight loss.

Culinary use

Use saffron to add aroma, flavor and color to rice, soups, sauces and other dishes. Grind threads first, then add the ground saffron to boiled water or directly to food. Ready-ground powder skips the grinding step. Follow the amount and timing in your recipe.

The U.S. Food and Drug Administration advises consumers to be wary of hype and notes that sound health advice generally rests on research over time rather than one study (FDA). For an individual weight-management plan or questions about a saffron extract or supplement, speak with a qualified health professional.
