What You Should Know
STS Sports Nutrition offers several fat burning supplements to help dieters achieve optimal weight loss. One such supplement is STS Metabolic Activator. The ingredient list is published on the official website and online ordering is supported. We could find no testimonials for the supplement and STS does not send out free trials. With fat burners, a free trial is important so dieters can gauge how the supplement reacts in the body. Stimulants can be overpowering for some dieters.
List of Ingredients
Green Tea Leaf Extract, Synephrine, Guggul, Vinpocetine, Bioperine, Cocoa Seed Extract and Yohimbe.
All of the ingredients in STS Metabolic Activator are listed with total amounts. This is ideal for the dieter who wants to take the right amount of a proven ingredient. First on the list is green tea leaf extract. Green tea is proven to improve weight loss, but only in amounts of 300 mg to 350 mg and more. This supplement contains only 150 mg of green tea leaf extract; too little to affect weight loss.
Synephrine is a stimulant with no clinical backing for weight loss claims. Some dieters complain of racing heart beat and hypertension after taking synephrine. There have been claims of liver damage and death associated with the ingredient, but the FDA has not pulled synephrine from the market.
Cocoa seed extract has antioxidant properties, much like green tea leaf extract. Antioxidants fight free radical damage, but recent reports claim dieters may be taking too many antioxidants; counteracting the positive effects of oxidants. Oxidants are produced when oxygen is converted to water in cells.
Bioperine is black pepper extract. When taken with other natural ingredients, Bioperine helps these ingredients absorb more effectively. There are no fat burning or weight loss benefits associated with Bioperine to speak of.
Yohimbe or yohimbine, is a sexual aid for men. The ingredient also has stimulating effects so the dieter will feel an energy boost after taking STS Metabolic Activator but not all stimulants are proven to increase weight loss.
STS Metabolic Activator sells for $20.69 per 60 capsule bottle. Warnings state that dieters with heart problems or those taking certain anti-depressants should not take this supplement.
