What is it?

Calorad is a weight loss liquid protein drink claiming to offer well-rounded weight loss results in just a few weeks. They advise to take this natural product for 3 to 5 months however, to experience all the benefits.

It claims to be able to benefit with the body by working alongside it, to help improve its absorption of amino acids.  Other benefits include more energy, better sleep, reduced cravings, a better sense of wellness, and an overall better physical appearance.  They add that it can help improve the look and quality of skin, hair, and nails, while providing safe and effective weight loss. So is this weight loss brand truly effective? What kinds of results are customers experiencing? You’ll see in this Calorad review what this supplement truly has to offer.

Calorad Ingredients and Side Effects 

Many different blends are available for the Calorad brand. Here are the main ingredients that the company lists: 

Oxygenated Water Bovine Collagen Hydrolysate Aloe Vera Glycerin
Potassium Sorbate Lemonade Flavoring Methylparaben Propylparaben

 Bovine Collagen Hydrolysate: Cow derived amino acid source which is made from crushed bones and cartilage. Collagen is the connective tissue that helps provide structure to the connective tissue.

It’s a quick absorbing protein source that is used by the body to create stronger hair and nails.  Possible side effects may include:

  • Bloating, heavy stomach, and gas.
  • Heartburn.
  • Allergic reactions. 

Since it’s made up of a mass of often discarded cow parts, there’s a possibility for contaminations that include mad cow disease.

Live also mentions:

“there is currently no evidence supporting (collagen hydrolysate’s) many claims” 

The manufacturers claim they have clinical studies showing this ingredient can help promote weight loss. Though these studies are not published, and it was not peer reviewed. This makes it impossible to verify the company’s claims. 

Aloe Vera: Natural plant ingredient used to provide a safe laxative effect. It’s also used as a topical ingredient, often to help soothe sunburns or to improve skin health.

It also has been shown to help with stabilizing blood sugar levels, and it has been used to help diabetics. 

Potassium Sorbate: Preservative used to help kill bacteria and mold. Clinical studies have shown this to be potential dangerous.

The Gazi University and Ankara University performed a study showing:

“clearly seen to be genotoxic to the human peripheral blood” 

This can make it extremely damaging to the human body, and it may even cause DNA damage that can make it a cancerous ingredient. Another study by the Osaka City University found:

“Mutagenicity and DNA-damaging activity” 

This effect can potentially lead to cancer.  Other possible symptoms may include:

  • Nutritional deficiencies, loss of vitamins and minerals, and digestive problems. 
  • Nausea, vomiting, and upset stomach.
  • Diarrhea.
  • Serious long-term health complications.
  • Doctors Health adds:

“There are many potassium sorbate side effects” 

“limiting how much you eat can prevent health complications” 

This ingredient is not advised by many health organizations, due to its many potential side effects. 

Methylparaben: Preservative often found in women’s cosmetics. It can have a toxic and estrogenic effect in humans.

It is a controversial ingredient that when eaten, is immediately absorbed by the digestive tract.

Live mentions:

“researchers suggest that methylparaben may increase the risk of breast cancer, or accelerate the growth of these tumors” 

“some researchers suggest that compounds… can cause decreased sperm production and motility” 

There were also concerns over its carcinogenic effect, especially when applied to skin:

“oxidative stress… is responsible for a number of disease processes, including cancer” 

A study featured in ScienceDirect also showed a potential negative effect to skin: 

“significantly increased cell death, oxidative stress” 

Propylparaben: Preservative found in shampoos, creams, and lotions.

The EWG Skin Deep website has rated it as a potential danger score of 7 out of 10, with 10 being an ingredient better avoided. It’s considered moderately toxic, due to its possible negative effects on organ damage.  The European Commission has stated this ingredient had side effects:

“endocrine activity have been documented in at last one study” 

Endocrine disruptors can damage and interfere with normal hormones. This may potentially lead to birth defects, cancer, and several other serious issues.

The FDA also does not regulate cosmetic ingredients, but they do mention:

“study published in 2004 detected parabens in breast tumors”

 A study by Burdock and Associated Inc. also found:

“Allergic reactions to ingested parabens have been reported” 

Many studies have confirmed this ingredient to have potentially damaging effects to the body. 

Calorad Quality Of Ingredients

There are many potentially damaging preservatives, and the only active ingredient for weight loss is bovine collagen.  Though this ingredient has only been shown to have an effect by the company’s unpublished studies.  These findings cannot be trusted until they’re available, and only if the data is actually good.

It’s impossible to judge for certain what kind of an effect this ingredient might have.  Due to the amounts of preservative used, and the lack of proof for weight loss, this isn’t a very good mixture of ingredients.

The possibility for serious damaging side effects makes this a risky supplement to take. The official website claims it’s safe to use, but no evidence is provided to prove these claims.

Collagen can also be purchased for cheaper elsewhere. Since this is the main active ingredient for weight loss, and the only proven safe ingredient is aloe vera, the overall quality of ingredients is poor.

The Price and Quality of Calorad 

The regular Calorad Classic offering 30 servings sells for $40.95 when purchased via the manufacturer.

The only ingredient added to this to help with weight loss is cow collagen. This cheap ingredient is made up of crushed bones and cartilage, which is often thrown away when slaughtering cows.

The rest of the ingredients are all preservatives. For the price paid, one is paying a large amount for one typically inexpensive ingredient.

Bovine collagen also needs to be specially treated in order to avoid possible contaminations. There’s no proof provided by the company to show that their product is formulated in a way to reduce possible contaminations. 

Business of Calorad 

Different businesses market this brand, but the makers are NutriDiem. They can be reached via the following: 

Phone Number: (888) 748-2566 


They offer a 30 day return on unopened products, but they apply a 15% restocking free.

Since different companies market this brand, there have been different claims made about the usefulness of this brand. There used to be marketing claims that Calorad:

“could (help you) lose weight while you sleep” 

However, this is no longer used as an advertising claim, as no evidence is available to help support his claim. The official website now states:

“Proven Effective… Safe and Clinically Tested” 

No proof is provided to help prove either of these claims.  When a brand is claiming to be proven effective, this usually means the FDA has shown this effect. Though the bottom portion of the website adds:

“statements made have not been evaluated by the Food and Drug Administration” 

So it’s unknown why the company would make these claims. Technically, what they are saying is not legal. No supplement can claim to be proven effective without being approved by the FDA.

Customer Opinions of Calorad

There are a few reviews available online. Here’s what some users have experienced according to

“Tastes terrible… Have to throw it out” 

“lost no inches but instead gained more pounds” 

“Will not be buying this product again or recommending it to anyone” 

“I haven’t seen any result” 

Many people failed to see any weight loss benefit. Some did say their sleep was improved, but none of the other claimed benefits were listed. This includes no mention of improved energy, endurance, or overall appearance.

Some said that thus spoils very quickly, even with all the preservatives added in. There were also a few complaints about the taste. Many claimed it was undrinkable, and that it had a sharp artificial taste.

Conclusion – Does Calorad Work?

Before you make a final decision on whether or not Calorad is for you, it’s important to look over all the data. This brand has not been well reviewed, and the company offers no evidence for the use of this brand. They claim clinical studies are available, but the only studies performed by other groups have shown potential side effects from the ingredients added.
