Poor digestion makes it difficult to break down food into usable nutrients. Pain, bloating, gas, cramping, and/or heartburn are some of the symptoms. This is usually caused by a lack of stomach acid or digestive enzymes. When poor digestion becomes chronic and severe, it can result in weight loss, muscle mass loss, wasting, pallor, and fatigue.

Taking digestive enzymes is the first step in resolving this issue. Proactazyme Plus is a good place to begin. Other options include Protease Plus, Food Enzymes, and PDA. It is also advisable to attempt to stimulate the body's natural digestive secretions. Chinese Anti-Gas, Anti-Gas Formula with Lobelia, Digestive Bitters Tonic, Safflowers, or Papaya Mint Tablets can all be beneficial.

Weak digestion, along with a lack of muscle mass, pale skin color, and fatigue, are symptoms of the Chinese formula Spleen Activator. The spleen in Chinese medicine refers to the body's ability to convert food into muscle mass. As a result of spleen chi weakness, it is impossible to gain muscle mass. Protein metabolism and spleen chi deficiency may also benefit from Trigger Immune, American ginseng, and saw palmetto.
