Multivitamins might not be the health boost you expect. Many contain cheap fillers like calcium carbonate and magnesium oxide, which have poor absorption rates. The debate over natural versus synthetic vitamins highlights that synthetic options often miss crucial cofactors. Plus, hidden ingredients like maltodextrin can spike blood sugar. With major brands often tied to big pharma, it's vital to be aware of what you're actually purchasing. Is your supplement doing more harm than good? It's time to rethink your vitamin choices!

Episode notes
INSIGHT

Cheap Minerals, Low Absorption

  • Many mass-market multivitamins use cheap mineral forms like calcium carbonate and magnesium oxide with very low absorption.
  • These inexpensive ingredients make bottles heavy but deliver little usable nutrition compared to bioavailable forms like magnesium glycinate.
INSIGHT

“Natural” Labeling Is Misleading

  • The label term “natural” is unregulated and synthetic vitamins can be marketed as natural despite originating from coal tar or petroleum.
  • Even identical molecules may differ in absorption and biological effect when isolated from their natural complexes.
ADVICE

Don't Rely On Single Isolated Vitamins

  • Avoid taking single isolated vitamins long-term unless paired with their natural cofactors.
  • Dr. Eric Berg warns isolated high-dose vitamins can deplete cofactors needed for normal biochemistry.
