Suggested Use: Take 3-4 capsules three times daily, or as directed by a healthcare professional.
Contraindications:

  • Not to be used during pregnancy or while breast-feeding.
  • Several ingredients in this formula have demonstrated hypotensive, vasodilator, and cardiodepressant activities in animal studies. People with low blood pressure should monitor their blood pressure for this possible effect.
Drug Interactions: This product may enhance or increase the effect of high blood pressure drugs.
Other Practitioner Observations:
  • Several ingredients in this formula have demonstrated significant in vitro antimicrobial properties. Supplementing the diet with probiotics (like acidophilus found in live-cultured yogurt) is advisable when this product is used for longer than 30 days.
  • Taking CoQ10 and other supplements which increase cellular ATP might reduce the effects of N-Tense.
