What We Like

  • 250mg magnesium as glycinate-lysinate chelate (vs Centrum's 50mg oxide).
  • Zinc picolinate (best-absorbed zinc form).
  • Natural d-alpha tocopheryl with mixed tocopherols (full vitamin E spectrum).
  • Selenomethionine (superior selenium form).
  • 500mg vitamin C.

Watch Out For

  • 8 tablets per day is commitment.
  • Premium price ($40-50/month).
  • CoQ10 at 10mg is still low.
