ADVICE

Test Vital Nutrients Often

  • Always test vitamin B12 and D levels in psychiatric patients to reverse mental illness.
  • Don’t rely on standard 'normal' lab ranges; B12 levels below 500 can still cause symptoms.
INSIGHT

B12 Absorption Issues in Aging

  • Aging and stress reduce stomach acid necessary for B12 absorption.
  • Low stomach acid and zinc deficiency cause many cases of B12 deficiency, not just diet.
ADVICE

Better Magnesium Testing and Signs

  • Use RBC magnesium testing, not serum magnesium, for more accurate deficiency detection.
  • Consider clinical symptoms like anxiety, constipation, and insomnia to guide magnesium supplementation.
