Nutratech is actively pursuing patent infringers to protect their Advantra Z customers

WAYNE, N.J., September 17, 2003 – Nutratech, Inc. – a research-based nutraceutical ingredient supplier – filed a
patent infringement lawsuit last week against Nutrabiotics Research Labs, Inc., a New Jersey Corporation, for using
patented claims on their labels and marketing materials reserved only for customers who purchase Advantra Z®
material. The lawsuit makes Nutrabiotics liable for making application claims pursuant to four current U.S. patents
(6,224,873; 6,316,499; 6,340,481 and 6,340,482) on labels and marketing material for their Thermofuel Beta 3,
Thermofuel Lite and LipoLean products that are protected by U.S. patents owned by Zhishin LLC and exclusively
licensed to Nutratech. These patents relate to the use of Citrus aurantium, bitter orange or citrus extracts for, but not
limited to:

• stimulating thermogenesis
• reducing weight loss
• increasing lean muscle mass to total body mass
• improving athletic performance and
• suppressing appetite

By purchasing Advantra Z®, Nutratech’s customers can utilize these claims, subject to their attorney’s comments
and/or approval, on their product’s label and marketing support material. This gives Nutratech’s customers a
marketing advantage over their competition that may be purchasing the generic Citrus aurantium, and therefore,
cannot legally make these claims.

“Since patents are only as good as the patent holder’s willingness to devote resources to defend and protect them,
Nutratech has decided to rigorously pursue companies who are infringing on these patents in order to protect our
customer’s competitive advantage in the marketplace,” challenges Bob Green, one of the principals of Nutratech.
Unlike generic counterparts on the market, most of the research on Citrus aurantium has been conducted using
Advantra Z®, which utilizes optimal harvesting techniques and a proprietary extraction process to produce a truly
unique synergistic amine composition. This complete composition of five synergistic adrenergic amines:
synephrine, n-methyltyramine, hordenine, octopamine and tyramine is responsible for delivering the applications
protected by the aforementioned series of patents and the positive results found in the research.

“And it’s this time and cost intensive investment that we want to make sure benefits our customers and not their
competitors who choose to use scientifically unsupported generic Citrus aurantium material in their diet and sports
nutrition products while riding the coat tails of our significant investment in research and product development,”
contends Marc Brucker, another principal owner of Nutratech.

In the wake of controversy surrounding the popular herb, ma huang (ephedra), Advantra Z® has emerged in the diet
and sports nutrition marketplace as the ideal thermogenic alternative, working as effectively as the former when
used properly without the potentially negative central nervous system and cardiovascular side effects.
Nutratech, Inc. with headquarters in Wayne, NJ provides innovative, proprietary and patented nutraceutical
ingredients with efficacy claims that are supported by sound scientific research.
