Many women use either an oral contraceptive pill or hormone replacement therapy (HRT). It is the oestrogen in these medications that causes the nutrient deficiencies. There are a couple of contraceptives and hormone replacement therapies that do not contain oestrogens but the vast majority do contain oestrogen.
Oestrogen containing oral contraceptives and HRT and nutrients depleted by them
Magnesium, zinc, B vitamins, vitamin C, most minerals and healthy microorganisms that live in our gut are depleted by oestrogen containing medications.
Deficiencies in these nutrients can cause fatigue, irritability, depression, insomnia, memory loss, heart disease, increased risks of stroke, breast cancer and other cancers, irritable bowel syndrome, nerve pain, hypothyroidism, candida and lowered immunity.
How to combat oestrogen nutrient deficiencies
A good quality multivitamin will provide the nutrients listed above. Healthy microorganisms can be gained from a good quality probiotic.
