What is Period Blood Made Of?
Period blood, also known as menstrual blood, isn't just blood. It's a complex mixture of several components shed from the uterus during menstruation. According to recent scientific studies, menstrual blood consists of:
- Water
- Dead endometrial cells: These are cells from the uterine lining.
- Lipids (fats)
- Proteins
- Stem cells
- Hormones: such as progesterone.
Basically, the blood we lose each period is nothing more than the uterine lining that your body did not use.
