Dietary deficiencies in micronutrient (vitamins, minerals, trace elements) are common in women and men of reproductive age, since these are scarce in the modern diet. Low levels of micronutrients in food are due to the way the food is processed and preserved from farm to table. Soil depletion, overfarming, early picking of unripe food for transport and prolonged storage at low temperatures are just some of the depleting factors.
Other significant contributors to micronutrient deficiency include the consumption of convenience/processed foods of low nutritional quality. Alcohol and smoking also destroy micronutrients.
To improve chances of getting pregnant, men and women should replenish their exhausted body storage of key micronutrients by having supplements to increase male and woman fertility.
