Even for those who don't conceive as a direct result of being on the programme, Foresight believes that they stand a better chance of success with IVF, GIFT and ZIFT by having first had their health and nutritional status enhanced (J of Nutritional Med, 1990; 1:251-58.)

A study conducted by Dr Stephen Davies, medical director of Biolab in London, noted that magnesium deficiency is associated with female infertility, increased miscarriage rate and increased incidence of premature and low birthweight babies, although the reasons why are not fully understood.

Davies and his team gave magnesium supplements to six magnesium-deficient women with unexplained infertility, whose magnesium levels normalized after four months of treatment. All six conceived within the following eight months and produced normal, healthy babies. Others with unexplained infertility whose magnesium levels did not normalize after four months' treatment did so after a further two months of magnesium plus selenium supplementation. These women also conceived within the following eight months, going on to produce normal, healthy babies (Magnesium Research, 1994; 7 (1): 49-57).
