The Navy SEAL Physical Fitness Guide 241
Nutritional Ergogenic Agents
Ergogenic agents are by definition, substances or techniques that enhance
performance. Because SEALs are required to perform at a high level both mentally and
physically, many are looking for substances or techniques to improve performance and
provide “an edge”. To perform longer, to be faster, to be stronger, and to be leaner, if not a
mission goal, are personal goals of many SEALs and elite athletes. People have been trying
to accomplish these goals for centuries through the use of ergogenic agents. It is our goal
to present information about certain products commonly found in retail stores or by mail
order, that claim performance enhancing effects. For a detailed discussion refer to The Navy
SEAL Nutrition Guide. Specifically, this section will provide information on:
" Nutritional Products Advertised as Ergogenic Agents.

Nutritional Products Advertised as Ergogenic Agents
This section lists many of the nutritional ergogenic agents sold by manufacturers
with claims to “enhance performance” or have “muscle building” properties. Some have
valid claims whereas others do not. It is often difficult to differentiate false claims from
valid ones if you haven't carefully researched each product individually. Many claims
sound very scientific and convincing but, unfortunately, they are often false or unproven.
For each agent described in Table 14-4, the claims, the usual dose used, and a comment are
provided.
