I've been having an interesting back channel discussion with another poster here about "carb" blockers. During the course of it, I actually, you know, READ the label on my old bottle of them. It states that it is ineffective against fruit, milk, and sugar. Hmmmm.....oh, sugars generally, fructose, lactose, glucose. This bottle is a K-Mart house brand and they correctly labeled it a Starch Blocker. Sometimes the truth is hidden in plain sight.
Said other poster told me that the pills used definitely did SOMEthing.....induced the runs. But I looked at the particular pills on the net and it is a light duty, by mg, starch and fat "blocker" combo. So who knows how much of that experience is due to the fat perhaps moving on through?
Another point of variability is in the use instructions. If you look at a lot of labels, you will find advice to take 15-20 minutes ahead of the starch, with the starch, and even before and after. (No harm in mopping up stray starch moleecules, I guess!)
Yet another variation is in the amount of extract. And hence, how many pills are are a "dose". Most hover around 600-750mg, the good guys are 1000mg, yet the respected NOW brand is only 500mg.
So, if you are still with me, you know pretty much what I know.
I'll add that some Mayo clinic evidence says that you need 4000mg. But then, they don't say how many starch grams it blocked. Maybe that was needed for Supersized fries?
Which opens up another unanswered question, is dosage in proportion to starch eaten, or does a certain minimal amount kill the alpha-amylase enzyme for awhile that converts starch to glucose?
