The hormone progesterone and menstrual blood clots are linked through the action of estrogen. An increased risk of blood clots can occur because the hormone estrogen thickens blood. Hormone imbalances induced by environmental poisons especially the so-called 'xenoestrogens' are thought by some authorities to be a primary cause of this.
To help reduce the risk of the occurrence of blood clots you should avoid all forms of estrogen and maintain adequate levels of progesterone.
In addition take between 15 to 75ml of Omega 3 essential fatty acids in the form of flaxseed oil or fish oils.
