We worked hard to ensure that our formulation is the best option.  Stress Killer Sleep

• is GMO FREE and GLUTEN FREE

• has more total nutrients

• uses the premium, more bio-available versions of key nutrients, like

  • Cholecalciferol Vitamin D3, which your body can use more effectively than the cheaper Vitamin D2 version

  • Zinc Citrate, which is more bio-available than Zinc Oxide

We also don't use certain crummy ingredients (like artificial colors) that we were amazed to see the competition using.  We refuse to skimp.
