Calorad Side Effects

Updated July 19, 2017

Since the 1990s, Calorad has become known as a miracle drink that helps you "lose weight and inches while you sleep" according to the Collagen Weight Loss website. This natural protein supplement, derived from beef or fish, has its critics but no known negative side effects.

Side Effects

Increased lean muscle mass, better sleep and reduced appetite are some of the benefits Calorad promises to deliver if you take the supplement for a three-to-five-month period. You may also experience less joint and arthritis pain, increased energy, more stamina, and improved hair, nails and skin, according to the Calorad website. Calorad is said to restore collagen, which the site says restores overall wellness and physiology. Negative side effects could result if you solely rely on Calorad for weight loss and do not eat a balanced diet while taking the drink.


To reap the positive side effects of Calorad, you must follow the supplement's restrictions, the product's website states. Do not eat or drink anything (except water) three hours before going to bed. Immediately go to bed after taking Calorad or you will reduce its effectiveness. Children and nursing or pregnant women should not take Calorad. Consult your doctor before adding this supplement to your diet.


Calorad works best during the first 90 minutes of sleep when the body is in a process of repair, according to the product's website. Although a balanced diet and exercise are not required for Calorad to work, both are recommended for maximum results.


Clinical exercise physiologist and consumer health advocate William R. Sukala, MSc., CSCS, does not believe that Calorad can increase lean body mass. He says, "Irrespective of what is claimed, muscle does not just spontaneously generate based on the consumption of a protein supplement." He suggests that not eating three hours before bedtime may be the "not-so-miraculous" cause of weight loss. Natural bodybuilder Dino Paul Pierce, who has a Bachelor of Science in Dietetics, says that Calorad could "work somewhat theoretically" and "may have some benefits" but he believes that the benefits are "far fetched."


When Canadian farmers complained that their chickens could not lay eggs because fatty liver syndrome had caused their chickens to gain too much weight, researcher and formulator Michel Grise was inspired to develop a formula to help their poultry lose pounds. He developed Calorad in the 1980s. After it helped the chickens, Grise developed a formula for humans. The original formula was also used to help cows and pigs slim down.
