Stacker
2
Stacker 2
is one of the newer fat burners on the market. It is manufactured
by NVE Pharmaceuticals, and is heavily promoted in magazine ads.
The company also sponsors a NASCAR racing car to get additional
publicity. Stacker 2 calls itself "The World's Strongest
Fat Burner."
The primary ingredients in Stacker 2 are Ephedrine, Caffeine and
Aspirin (ECA). Like other ECA-based products, Stacker 2 works
by inducing thermogenesis (the production of heat), which speeds
up your metabolism and burns calories. Stacker 2 also has an appetite-suppressing
effect, so you feel less hungry and therefore eat less. (For more
about how Stacker 2 works, see Does
Stacker 2 Work.)
The most powerful component in ECA-based supplements is ephedrine.
It's long been regarded as a fairly potent thermogenic compound,
but it was found to be even more effective when combined with
caffeine and aspirin. It's true that caffeine is also a fairly
good thermogenic compound, but it hardly measures up to ephedrine.
When caffeine and ephedrine are combined in fairly specific ratios,
the results are synergistic. In other words, the effects of each
are greater than the sum of their individual effects. The studies
that produced dramatic synergies used a caffeine/ephedrine ratio
of 10 to 1. In fact, this ephedrine/caffeine combination produces
a synergistic fat-burning effect that is even more effective than
the once-popular diet pills Fen-Phen and Redux. When aspirin is
thrown into the equation, the results are further enhanced. (For
more studies on Stacker 2 and its ingredients, see Stacker
2 Reviews.)
Stacker 2 uses an 8:1 caffeine/ephedrine ratio, so proportionally
there is more ephedrine than with the 10:1 ratio. Since ephedrine
is the stronger of the two ingredients, this could produce a stronger
product as their logo claims. However, this ratio has not been
tested in clinical trials, so it cannot be said whether it produces
any greater fat loss than the traditional 10:1 ratio does.
Although for most people Stacker 2 is quite safe, if you have
a history of heart or thyroid disease or drug abuse, an enlarged
prostate or high blood pressure, you should definitely check with
your doctor before you take this product.
