Slender Blend Ingredients and Side Effects

Here are the ingredients to their vanilla flavor:

Whey Proteinconcentrate Skimmed Milk Powder Natural Flavorings Magnesium Oxide Potassium Chloride
Ascorbic Acid Mixed Natural Tocopherols Zinc Gluconate Ferrous Fumurate Vitamin K2 Menaquinone
Molybdenum Chelate Manganese Gluconate Beta Carotene Curpic Gluconate Nicotinamide
Calcium D-Pantothenate Pyridoxine Hydro-Chloride Thiamin Hydrochloride Riboflavin Cholecalciferol
Methylcobalamin Chromium Picolinate Folic Acid Potassium Iodide Sodium Selenite
D-biotin Guarana Extract Green Tea Extract Sunflower Lecithin Sucralose

Whey Protein Concentrate:Extracts from the cheese making process which is made up of around 29% to 89% protein by weight. It’s considered high quality protein strain, and it contains all the essential amino acids.

Often used by athletes as a way to increase the size of muscles. Whey is also an easy to digest protein source.

Guarana Extract: Seeds of this plant are found in the Amazon where they are used as a medicine. It contains stimulants such as theobromine and caffeine which stimulates the muscles and heart.

Web MD has stated:

“Guarana is POSSIBLY UNSAFE when taken by mouth in high doses for a long time”

“At typical doses, the caffeine in guarana can cause insomnia, nervousness and restlessness”

Other possible side effects can include:

  • Nausea, vomiting, and rapid breathing.
  • Difficulty breathing, agitation, and anxiety.
  • High blood pressure, rapid heart rate, and jitters.
  • Cold sweats, muscle spasms, and headaches.
  • Stomach cramps, increased urination, and ringing in the ears.
  • Delirium, pain in the chest, and irregular heartbeat.

Without knowing the full amount of caffeine from guarana, it’s impossible to determine whether or not it’s added in safe dosage strengths. Often this amount varies from person to person, as well as whether or not one takes stimulants from other foods such as coffee, tea, chocolate, and others. A full list of the highest rated meal replacements are available in the link listed here.

Green Tea Extract:This common tea extract has a high amount of antioxidants and caffeine. It’s commonly used as a weight loss ingredient since it’s cheap to add. The National Center for Complementary and Integrative Health adds:

“There have been some case reports of liver problems in people taking concentrated green tea extracts”

They also studies whether or not it had any weight loss potential:

“There are not enough reliable data to determine whether green tea can aid in weight loss” has also stated:

“Any fat burning benefits are dependent on beingcaffeine naïve”

Though caffeine can increase metabolism for a short while, the body quickly creates a tolerance which reduces its overall effects. There is also a possibility for side effects such as:

  • Vomiting, indigestion, and nausea.
  • Rapid heart rate, irregular heartbeat, and cardiovascular issues.
  • Insomnia, difficulty relaxing, and restlessness.
  • Headaches, ringing in the ears, and anxiety.
  • Jitters, cold sweats, and muscle spasms.

Much like the added guarana, without knowing the full amounts of caffeine, it’s impossible to determine whether or not one is getting a safe dosage. This can be potentially damaging to health, as caffeine can promote many side effects. It may also negatively interact with other stimulants and can be potentially damaging to overall health.      

Sucralose:Artificial sweeter that is not broken down by thebody. Multiply studies have shown it to be potentially dangerous to overall health. One such study was performed by the Journal of Toxicology and Environmental Health, they found:

“Exerted numerous adverse effects, including reduction in beneficial fecal microflora, increased fecal pH, and enhanced expression levels of P-gp”

When gut microflora is reduced, it raises the possibility for immune system issues. Also, increased P-gp only occurs in the body when a potential contaminant enters the body.  It’s the body’s way of getting rid of sucralose.

They were subject to a controversy for claims that they added 17 times more carbohydrates than what’s stated in Slender Blend.  One scientific study saw that it claimed to have 2.2 grams of carbohydrates per serving, but it instead had 38.5 grams.

A scientist who held these studies was quoted as saying:

“The declared nutrition information was outside acceptable tolerances of accuracy which is potentially misleading”

An investigation into the company was held by the ASA or Advertising Standards Authority, which helps make sure that any advertisements in the UK are truthful.

They reviewed the marketing clams made for Slender Blend and how it can create a healthier body and reduce food cravings.  The company was forced to stop making these claims, and they also had to stop making any more exaggerated claims in the future. Still the ASA responded back by stating:

“Slender Blend” was in itself a health claim, which implied weight loss. We had not seen evidence that “Slender Blend” was an authorized health claim”

The ASA sent another notice warning the makers of Slender Blend to not make false health claims about their meal replacement.
