Nature's Sunshine Protein Digestive Aid 180tabs

Title :

1 In Stock

Protein Digestive Aid supplements the body's hydrochloric acid with betaine hydrochloride, which supplies diluted hydrochloric acid. It also adds pepsin, a natural protein digesting enzyme, making it a complete protein digestive aid

Special cells in the stomach lining require vitamin B-complex and other nutrients to manufacture hydrochloric acid to break down proteins during the digestive process. As the human body ages, its ability to produce hydrochloric acid decreases.

Each tablet of PDA provides 325 mg of betaine HCl and 20 mg of pepsin.

Indications for use

Adds hydrochloric acid to supplement normal body acids

Contains pepsin for natural protein digestion

Helps supply enzymes lacking in the diet

Supports smooth, comfortable digestion


Per 4 Tablets

Betaine (betaine HCl) 1,300 mg

Pepsin (contains milk) 80 mg

Recommended Dose

Adults: Take 1-4 tablets with a meal three times daily.
