BioRythm is the manufacturer of SynthroLean and they make some observations about finding the right weight loss supplements and aids. One such observation is that dieters shouldn’t have to have the jitters in order to know that a fat burner is doing its job. They go on to state that dieters who are looking for energy supplements should possibly stick with stimulants and supplements that are made for that reason. SynthroLean, they say, is intended for only those dieters who are serious about losing fat.

The makers of SynthroLean claim that they produce a superior product that will increase metabolism, not just give dieters a higher heart rate, the jitters and increased blood pressure. They state that this product works because it increases the metabolism, enhances thyroid functions, increases energy levels and provides improved transportation of nutrients throughout the body.

List of Ingredients

BioRythm, the manufacturer of SynthroLean, includes a list of ingredients and descriptions of each component on their official website. The list almost looks like a listing of active ingredients instead of a complete list. The listed compounds are: B Complex, L Tyrosine, Coleus Forskohlii, 3b Acetoxyandrost 5 Ene 7 17 Dione, Choline, Inositol and Guggulsterones. p>

Product Features

SynthroLean is a fat burner that is taken in pill form. The manufacturer’s website does not give adequate information regarding usage instructions. The 90 capsule bottle does say that it contains 45 servings which would suggest that two capsules should be taken at a time, though it is unclear what times or how many times in a day it should be taken. Many Bodybuilding sites discuss this product and give good reviews on its fat burning properties.
