Let's talk about placenta calcification - aka "the aging placenta"
In this image is a teeny little placenta from a home birth that I attended. The doctor declared the placenta as Grade 3 calcification at 36 weeks, and this precious baby was born naturally at 38 weeks, healthy and at home with zero complications. Was she tiny? Yes. But she was perfect.
A Grade 3 placenta at 36+ weeks is often described as a “mature” or “calcified” placenta on ultrasound. The important thing to understand is that this grading system describes how the placenta looks - not how well it’s functioning.
Research has shown that placental grading alone is a poor predictor of placental insufficiency, fetal distress, or stillbirth. In fact, Grade 3 placentas are commonly seen in healthy term pregnancies and are considered a normal part of placental maturation toward the end of pregnancy.
Likewise, a baby measuring “small” on ultrasound does not automatically mean the baby is unhealthy or unsafe. Ultrasound weight estimations have a fairly large margin of error, AND many babies are simply constitutionally small (just like some adults are naturally smaller than others).
What matters more than placental appearance or baby size alone is doppler blood flow; amniotic fluid levels; baby’s movement patterns, growth trends over time, and overall maternal and fetal wellbeing. A single scan should never be viewed in isolation.
This doesn’t mean that concerns should be ignored, only that decisions around induction and birth planning deserve a full clinical picture, not fear-based assumptions from ultrasound findings alone.
If you want to naturally support the health and wellbeing of your placenta and baby, then consider these options:
🥚 Adequate daily protein intake
🥑 Healthy fats and omega-3s
🌿 Iron-rich foods and mineral support (especially whole-herb options like Nettle leaf and Spirulina)
🚶♀️ Gentle daily movement
💤 Rest and stress reduction
💧 Good hydration
There is no consistent evidence that a Grade 3 placenta automatically signals dysfunction. Every pregnancy is unique, and evidence-based care means looking at the whole picture - not just one ultrasound label.
