Saffron can function as an effective energy booster and can increase your metabolism by increasing your blood circulation. A study, which was conducted and later published in the Phytomedicine Journal, had a group of healthy volunteers evaluate the short-term safety and tolerability of saffron stigma tablets. These volunteers were divided into 3 groups of 10 each, ie 5 males and 5 females. After consuming these tablets for a week, it was noted that saffron decreased slightly some of the hematological parameters like the red blood cells, hemoglobin, hematocrit, and platelets, while increasing the sodium, blood urea nitrogen and creatinine levels.

The high concentration of iron in saffron means that it increases the RBCs in your body, which thereby stimulates circulation and the oxygenation of organ systems and the body’s extremities. This improves the efficiency and functionality of the tissues and organ systems for healthier metabolic activity and also prevents the symptoms of anemia.
