Jackson or Hay, both methods work, but Dr. Hay used an alkaline water solution the first 3 morning for beginners; to cleanse the stomach and making fasting easier.
8-9 LBB capsules taken every day while fasting is like insurance in the bank
commercial capsules I have zero clue what they used----most, including christopher name uses 0 size, which are tiny.......the christopher company sold many times, destroying (removing) the best herbs so they could ship to canada and out of country I assume----the last building I knew of 26 years ago was torn down...1 mega utah manufacturer I believe makes over 600 brand names-----all of which I will assume to be about worthless. The only way to know is try them after you read their labels on line.
The jackson and Hay books are on line, on cure zone, read their books first.
