FOODS FOR FERTILITY
Four key nutrients to be aware of

With all the differing opinions out there, you can rest easy that these four are agreed on to optimize fertility + pregnancy health across the board—
↠ B12 : low levels are associated with miscarriage
↠ Folate : prevents neural tube defect
↠ Choline : enhances the transport of nutrients across the placenta (a real rising start in being recognized as a must-have)
↠ Omega-3 : anti-inflammatory; the backbone to hormone production
These are four main players you should be looking for in your pre-natal vitamin and also what you should be filling your kitchen with.
Remember supplements are intended to fill gaps- not be your main source. Your prenatal will go loads further if you're building a strong foundation for yourself through diet.
