Vitamin J is an old term for choline. The term "vitamin J" was also used by some researchers to denote vitamin C2, Chatechol (flavin), a bioflavinoid. Choline assists in fat metabolism. It supports the action of bile salts by reducing the surface tension of fat particles, making them more easily emulsified by the bile salts.

You would use this product with the patient who has extreme difficulty digesting fat foods. Let's say the patient has already tried A-F Betafood and Cholacol and still has difficulty with fats, then you would give him Choline. Any patient with venous congestion, hemorrhoids, constipation or a pasty complexion due to incomplete fat digestion is likely to need this product.
