Why does some blood smell very strong metallic and others more sweet? is the blood type or does the metallic type mean there's anemia or another condi

Metallic blood: Most people think the metallic smell from blood is due to iron or other heavy metal traces in blood. The sweet smell may be the absence of metallic smell, and may indicate a lower hemoglobin levels, requiring supplementation. Blood type seems not be important factor in blood samell. BTW, where did you get to smell all that blood?:) Should we be on standby!

Blood odor: The odor of menstrual blood varies with the amount to "dilute" its mixture with vaginal secretions, and whether there is concurrent bacterial or yeast components. The odor has very little to do with "blood type" and/or anemia.
