Query: Didn't do anything

I decided to purchase Lipovarin based on the reviews. However, other than making me irratable, they did not do anything. I will add that there were times when I did not take the full dosage recommended, but I did try them for a full month. I am now back to Trimspa and have lost 6 pounds.
