Amyl Guard functions by preventing the enzyme amylase from doing its job, which is to convert complex carbohydrates into simpler sugars the body can absorb. If these sugars are not used for energy right away, they are frequently stored as fat. Amyl Guard works by inhibiting amylase, which stops carbohydrates from quickly becoming sugars that store fat, therefore lowering the total number of calories that can be absorbed from a meal. Inhibiting amylase results in undigested carbohydrates passing through the digestive tract unabsorbed.
