Beef organ supplements are a nutrient powerhouse, but with naturally rising copper in pregnancy, we just need to be cautious and test levels first.
Because high copper can lower zinc (crucial mineral for literally everything) and increase oxidative stress, both associated with higher risks of pre-eclampsia and preterm birth.
Here is a rough guide:
• Serum copper: ideally ≤15 µmol/L (it will rise each trimester though)
• Plasma zinc: aim ≥10–11 µmol/L. I ideally like my clients sitting around 15-18
Zinc dosing (individualised & monitored):
• Zinc 15 mg/day if zinc is borderline
• Zinc 25 mg/day if zinc is low or copper is on the higher end
• Zinc 30 mg/day short-term if deficiency is confirmed
Everyone’s zinc requirements are different, but from my clinical experience, I tend to prescribe my clients with quite high doses of zinc to achieve an optimal zinc copper ratio. But if you’re not under the care of a health care practitioner, I don’t recommend dosing too higher than this guide. And if you haven’t been taking zinc before pregnancy, increase slowly and gradually — zinc can mobilise stored copper, which may cause symptoms if introduced too quickly.
I hope this is helpful. Leave any questions in the comments 🤍
