In healthy subjects not receiving or requiring lipid lowering therapy and who do not have diabetes, the use of clinoptilolite (GPUR) will result in a reduction of absorbed dietary cholesterol observed over 6 days of therapy.

Condition Intervention

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: 39 Day Randomized, Open Label, Two Arm Cross Over Study of Clinoptilolite (Gpur) in Healthy Adult Subjects Not Requiring or Receiving Lipid Lowering Therapy

Further study details as provided by Canadian Collaborative Research Network:

Primary Outcome Measures:
  • Percent change in fractional cholesterol absorption in human subjects taking clinoptilolite over 6 days [ Time Frame: 39 days ]
    Primary Objective

Secondary Outcome Measures:
  • Percent change from baseline by gender to determine gender difference in fractional cholesterol absorption rates [ Time Frame: 39 days ]
    Secondary Objective

  • Percent change from baseline to end of treatment to evaluate for safety changes in metabolic profile measurements [ Time Frame: 39 days ]
    Secondary Objective
