Meratrim is manufactured by InterHealth, an FDA certified lab based out of California. It is an innovative combination of two plant extracts, Sphaeranthus indicus, a flower, and Garcinia mangostana, a fruit rind. Weve looked at hundreds of different ingredients that claim to aid with weight loss. Of the ingredients weve researched, Meratrim definitely stood out from the crowd. Meratrim is the first patented supplement additive weve seen that combines these two ingredients for maximum effect. Weve seen everything from exotic plant extracts to patented synthetic chemical compounds. What we really liked about Meratrim is that its a caffeine free, non-stimulant metabolism booster, which means users can accelerate their metabolism without feeling jittery or any of the other side effects typically associated with caffeine.
