iSatori Energize Caffeine Pills

iSatori Energize time-release caffeine pills are designed for sustained energy. A serving of two tablets contains 196mg of time-released caffeine. This amount is roughly equivalent to two standard 8-ounce cups of brewed coffee (80-100mg each). The time-release formula aims to provide extended effects and avoid a sudden crash.

BeachBody Performance Energize Pre-Workout

The BeachBody Performance Energize pre-workout is a powder mixed with water, taken before exercise to enhance performance and focus. It contains caffeine from natural sources like green tea and coffee bean extract. A one-scoop serving provides 100mg of caffeine, comparable to a single 8-ounce cup of coffee. The formula includes other ingredients such as beta-alanine and quercetin for performance.

XXL Nutrition Energize Powder

XXL Nutrition offers an Energize Powder, a sugar-free drink mix for energy or pre-workout use. One scoop contains 80mg of caffeine, a more moderate dose. It also includes taurine and B vitamins.

In some markets, 'Energise' is available as a ready-to-drink energy beverage. This drink contains 36mg of caffeine per 100ml. A 330ml can has approximately 119mg of caffeine.

Other Sources: Account for all caffeinated items consumed daily.

For a quick lift: The Energise Energy Drink is a convenient, moderate option.

The Role of Caffeine in Performance

Caffeine is an ergogenic aid known to improve athletic performance by stimulating the central nervous system and delaying fatigue. Benefits can be dose-dependent, but so are the risks of side effects. Doses between 3-6mg per kilogram of body weight are often effective for performance.

Potential Side Effects of Excessive Caffeine

Jitters and Anxiety: High doses can cause nervousness.
Elevated Heart Rate: Caffeine is a stimulant that increases heart rate and blood pressure.
Insomnia: Late consumption can disrupt sleep.
Digestive Issues: Some experience stomach upset.
