Of all people, we expected Bob Harper, celebrity personal trainer and trainer for the hit reality show, The Biggest Loser, to know the difference between weight loss supplements and cleansing supplements. Dieters often turn to colon and bowel cleansers to lose weight fast, but these supplements offer short-term solutions to a long-term problem. Overeating cannot be cured with a laxative, but diet supplements can help control hunger so the dieter learns how to eat better. Bob Harper’s 7 Day Cleanse is designed to jump start weight loss. What the ingredients provide, however, is a laxative and diuretic effect.

List of Ingredients


  • Calcium
  • Acai
  • Senna Extract
  • Turmeric
  • Papaya
  • Plum

Product Features

The ingredient list for Bob Harper’s 7 Day Cleanse is nothing more than an antioxidant and laxative. A laxative is the main ingredient for all cleansing supplements, but some companies choose non-stimulant laxatives and others choose stimulant laxatives. Senna is a stimulant laxative. The herb will cause muscles of the intestine to contract, forcing waste from the body. The body will react by collecting as much water as possible to lubricate the intestinal tract, leading to dehydration and possible constipation days later.

Turmeric is an interesting ingredient due to recent clinical information suggesting the spice has thermogenic properties. Unfortunately, combining proven or nearly proven ingredients with senna is the same as wasting the ingredient. The body will force waste out faster than other ingredients can be absorbed. In some cases, senna causes severe diarrhea and electrolyte imbalance.

Acai is another wasted ingredient. The superfruit has a high ORAC level, which means it is a strong antioxidant. Unfortunately, for the reasons stated above, this ingredient is wasted in a laxative supplement.

Bob Harper’s 7 Day Cleanse is a laxative, plain and simple. The dieter could choose any cheap colon cleanser or senna supplement and achieve the same results. It is best to take the remaining ingredients in this formula after the 7 day cleanse when the body can utilize the ingredients. It is important to drink lots of water to prevent dehydration and keep the bowels lubricated. Water also helps a dieter feel full and remove toxins from the body.

Bob Harper’s 7 Day Cleanse is nothing more than a mild colon cleanser. The supplement contains a stimulant laxative, which is common but dangerous. There are plenty of natural colon cleansers like psyllium and glucomannan that work to reduce hunger and gently remove waste. Stimulant laxatives contract bowel muscles. Senna can cause cramping, diarrhea, nausea and constipation.
