Hi Emily,
Both Organic Fiber Bars and FitSmart Bars provide an excellent source of fiber, and a diet high in fiber helps with weight loss as well as bowel regularity. The combination of fiber plus protein in FitSmart bars makes them a good meal supplement, which is why they are part of the Fiber35 Diet line. Protein helps with muscle building, which is an essential part of the Fiber35 Diet nutritional program, and it also helps provide a needed energy source throughout the day.
Organic Fiber Bars are strictly fiber and will help with constipation simply by increasing the amount of insoluble fiber you consume, but they will not relieve constipation on their own. For that, we recommend CleanseMORE or ConstipationSTOP. Remember always to drink plenty of water (at least half your body weight in ounces every day) when you are increasing your fiber intake, or the bars may actually have the opposite effect—contributing to feelings of constipation. Regular cleansing, daily probiotics and a daily Omega oil supplement are also recommended to promote regular, healthy bowel movements.
Good luck!
