Ephedra and ephedrine, (the alkaloids of ephedra which are the byproduct of ingestion and assimilation) are pretty much banned for weight loss use. It may still be found in fat loss supplements in the UK, though usually in fairly small amounts, that does NOT guarantee any weight loss. However, supplement researchers have discovered a way to create a synthetic version of ephedrine called Synephrine/bitter orange that is extremely efficient, stable, and regulated. It works very similar to ephedra and without the caveats of dangerous side effects associated with it. We recommend a Synephrine product Phen375 and/or if you are looking for even better thermogenic fat burner, we rcommend you check out Instant Knockout, that also contains 'glucomannan'.
