Unlike either Phentermine Adipex or Ionamin, Herbal Phentermine does not require a prescription. As claimed by the makers of Herbal Phentermine: "Herbal Phentermine is a Non-Prescription appetite suppressant that is 100% natural and safe. Scientifically designed to create the similar effects of the popular prescription phentermine version, Herbal-Phentermine works to increase your metabolism, suppress your appetite, burn calories and increase energy.

Another difference is that Herbal Phentermine is also not FDA approved, unlike the prescription Phentermine. Basically, the Herbal Phentermine makers can say anything they want about their product with little to no evidence to back it up.
Herbal Phentermine includes that following ingredients: L-carnitine, green tea, Camellia Sinensis, Alpha Lipoic Acid, Bioperine and Piper Nigrum, and Biotin.
L carnitine - One of the key uses of Acetyl L-Carnitine supplement
is for fatty acid oxidation - helping users burn unwanted
body fat. Fatty acids are one the key energy sources
the body uses, and oxidation is the process by which
they're broken down to create energy. The fatty acids
cannot penetrate the inner mitochondia membrane (where
they are burned for energy), and the key role for
L-Carnitine is to transport fatty acids accross the
mitochondra membrane to allow for oxidation of the
fats.
Green tea extract is also a common
ingredient in many fat burners - it helps with thermogenesis
and helps the metabolism of fat. It works without
increasing the heart rate which is most often associated
with most fat burners. With green tea, dieters get
the weight loss without the jitters and side effects.
Alpha Lipoic Acid is an antioxidant,
and is widely used in prevention of various diseases.
Its main function is to increase production of glutathione,
which helps dissolve toxic substances in the liver.
An antioxidant helps neutralize free radicals in our
bodies and protects our cells from damage.
Biotin (Vitamin B7) is a water-soluble vitamin, generally classified as a B-complex vitamin. After the initial discovery of biotin, nearly forty years of research were required to establish it as a vitamin and categorized as a Vitamin B.
