The manufactures of Xenadrine-NRG, claim that Xenadrine-NRG is an extended-release energy supplement and its patented formula is specifically aimed at increasing energy levels within 30 minutes and then enables it to sustain those levels for up to 8 full hours.

Strangely, the company is promoting Xenadrine-NRG less as fat burners pill and more as an energy booster and nutritional supplements. But the fact is Xenadrine, with almost all energy boosters, contains heavy quantities of caffeine. It may be said without fear of contradiction that Xenadrine-NRG pills are hard-pressed aspirin sized pellets, and when consumed these small pellets are slowly absorbed by the body system. This slow and gradual absorption of the pills allows for a continuous sustained dose of caffeine.
