Sleep, stress, movement, and nutrition are integral in planning and emerging understanding considers up to a three-generation impact on the development of chronic disease in their offspring.

According to American College of Obstetricians and Gynecologists (ACOG)1, preconception nutrition helps handle the extra demands on the body as the pregnancy progresses. The goal is to balance getting enough nutrients to support the growth of the fetus and maintaining a healthy weight.

Food & nutrients to support biologic processed need extra emphasis such as:

  • Folate, B Vitamins & methylation co-factors – needed for rapid DNA synthesis and cellular growth
  • Prebiotic- and probiotic-rich food – beneficial for digestion and absorption
  • Phytonutrient Diversity

Diet considerations for men for preconception:
