Irwin Naturals System Six contains the exact same ingredients as System Six with Xenedrol and the Triple Tea Fat Burner. Selling three products with three different names but the same ingredient list may seem like a great way to sell triple the products, but it is also a way to lose customers. If your weight loss product works, there is no reason to trick the shopper into buying more by changing the label.

List of Ingredients

Vitamin C, Vitamin E, Thiamin, Riboflavin, Niacin, Vitamin B12, Pantothenic Acid, Selenium, Chromium, Fish Oil, Cola.

Xenedrol Blend: Advantra Z, Eleuthro Extract, Gotu Kola Powder, Cayenne Extract, Guarana Extract, Mate Powder, Betaine Hydrochloride.

Garcinia Extract, St. John’s Wort, Tribulus Extract, Creatine Monohydrate, L-Carnitine, L-Tyrosine, Choline, Inositol, Spirulina, 5-HTP.

Bioperine Complex: Bioperine Extract, Ginger Extract.

Product Features

We immediately notice some problems with this weight loss supplement. Irwin Naturals System Six contains Tribulus Extract, St. John’s Wort and Creatine Monohydrate. If a dieter purchases this supplement with the idea of losing weight, these three ingredients will do nothing for that goal.

Tribulus Extract is a testosterone booster that simply does not boost testosterone. There is a lack of clinical evidence that tribulus does anything at all. St. John’s Wort is a mood booster and natural depression treatment. Again, no weight loss support. Creatine monohydrate is nearly NEVER included in weight loss supplements or fat burners. This ingredient is more commonly used in bodybuilding supplements to improve muscle growth. It has been known to cause water retention in muscles. That could increase weight not decrease weight.

The Xenedrol Blend is packed with stimulants. Advantra Z is another name for synephrine. Synephrine can cause negative side effects like elevated heart rate and increased blood pressure. The addition of more stimulants to the supplement will only increase that risk.

The Bioperine Complex is added to increase absorption. Bioperine, also known as black pepper, is commonly used for this purpose. Bioperine is just a brand name. Ginger extract may aid in digestion and work along with the black pepper.

Irwin Naturals System Six sells for about $15 per bottle. Ironically, the Irwin Naturals System Six with Xenedrol is marketed for men only.

  • Irwin Naturals lists ingredients online.
  • The product is much cheaper than other weight loss products.


  • The ingredients are the same for three Irwin Naturals products.
  • System Six is for everyone but System Six with Xenedrol is for men (though they have the same ingredients).


There is no reason for a manufacturer to sell the same product under three different names. Consumers will likely figure out what is happening when they fail to lose weight with any of the Irwin Naturals products. Creatine is not for everyone nor should dieters take this ingredient to lose weight.

    Would taking this product 6 at a time have adverse effects on one’s liver. Mine seems to be sore.
