What is important is the total amount of fiber you consume per day. A minimum of 25 grams per day is recommended by Heart Associations while wholistic Doctors believe it should be in the low 30 grams.
So the amount you need of this supplement, where a capsule is almost a gram, depends on how much food based fiber you are consuming. So, if you have a prepackaged meal, for example, it will tell you how many grams of fiber. Normally you will see fiber content is very low. A slice of even vegetarian pizza will have only 1 gram of fiber
Personally if I'm eating a sandwich with bread, pasta, other carb rich foods, I will take an additional half dozen or so of these capsules to help balance the high carb, low fiber food content. Normally I take a few several times throughout the day. Fiber supplementation is one of the most important supplements we can take. Hope this helps Richard.

  Each of these capsules contains 880 mg (0.88 gm) of psyllium husk, which is nearly all fiber.

The Harvard School of Public Health has issued these guidelines for recommended daily fiber intake for children, men, and women:

  A serving size is (1) capsule; however the directions call for taking one or two capsules one or two times per day with a minimum of 8 pz of water. I take two every night with my other medications. I have used this product VS-2182 (600 capsules) for 28 years. There are 880 mg of Psylium (Plantago ovata) (husk) (fiber) and 10 mg of Lactobacillus acidophilus in each capsule. I've taken it to keep my colon clean. The Acidophilus keeps the ph balance in your colon with 10 mg of 'good' bacteria. It provides (4 million live organisms) in each capsule at the time of encapsulation. Those organisms are the good bacteria. The product is the best for the money!
