There are many supplements which help achieve a flat tummy due to bloating.
Bloating is probably the primary cause of a distended stomach. If having a flat tummy is your objective, these supplements will help you achieve that goal. Bloating is also often a sign of a lack of digestive enzymes since these are involved in the complete breakdown of carbohydrates, fats and proteins. Broad spectrum digestive enzymes will help alleviate this concern as do herbs such as artichoke and ginger which stimulate the body to produce its own digestive enzymes.
Best Sellers include Flat Tummy Plus tablets and Enhanced Super Digestive Enzymes by Life Extension.
