Fennel is an aromatic plant commonly used in Italian dishes, noted for its delicate, flavorful taste and thin texture. It commonly grows in the Mediterranean but is only grown in other areas of the world, including Canada and Southeastern Asia, but is mass produced around Italy, where it is popular with chefs and cooks. Fennel contains a low carbohydrate count, ample amounts of Vitamin C, and is considered an important herb in various low-carb diets because of its nutritious, low-carb value. Recently diet companies have utilized Fennel in supplements that claim to cure IBS while helping dieters lose weight.

Fennel is a widely available, nutritious plant used heavily in culinary dishes, but it also being used in supplements because of these same properties. Some even claim Fennel can promote weight loss, along with curing several digestion-related diseases. Although the use of Fennel may contain nutritional benefits, some question the legitimacy of its dietary benefits.


Fennel contains Thiamine, Riboflavin, Niacin, Pantothenic Acid, Vitamin B6, Folate, Vitamin C, Calcium, Iron, Magnesium, Phosphorus, Potassium, Zinc, and Manganese. It also contains seven grams of carbohydrates and three grams of dietary fiber.

Product Features

Several diet companies claim that Fennel regulates digestion, resulting in weight loss. There is sufficient evidence that Fennel helps normalize digestion due to the chemicals contained in its extract form. It may be a safe supplement for treating constipation, although these statements are only backed by herbalists. No studies have revealed any dietary benefits, however, and these appear to be only undocumented claims made by various diet companies. Its nutritious value should not be underrated, however, and it often suggested it is a potent flavoring agent for spicing up low-carb meals. There are also no known side effects associated with Fennel, which is a rarity. Most herbs contain some unpleasant side effects.
