Although there is are no superfoods or supplements that have been proven to help with fertility, to give yourselves the best chance when planning a pregnancy, it is advisable for both men and women to eat a healthy balanced diet, to moderate alcohol intake (under 2 units a week), and to aim for a healthy weight (see our page on seeing if you are a healthy weight here). 

Being a healthy weight is particularly important for women – women with a healthy weight (body mass index between 20 and 25) have been found to be more successful at getting pregnant than women who are overweight or underweight. 

 Here is more advice for women trying to get pregnant

• take a daily 400 microgram folic acid supplement, and carry on taking it until the 12^th week of pregnancy. This helps to prevent some birth defects.
  
  
• eat fish weekly because of its healthy oil content, but don’t have more than two portions of oily fish a week. Oily fish includes fresh tuna (not canned tuna, which does not count as oily fish), mackerel, sardines and trout. Other goods sources of these healthy fats are rapeseed oil, olive or omega 3 rich spreads, omega 3 enriched eggs, omega 3 enriched milk, nuts and seeds.
