Energy Supplements

There are many factors that can affect energy level throughout the day. Nutrient deficiencies, insufficient carbohydrate fuel, stress, depression, fatigue and lack of restorative sleep can all affect liveliness and lust for life. Before slugging down those cups of coffee, read on to find out the many ways there are to improve alertness and vitality.

Energy-Boosting Supplements: Exercise Performance

Thermogenic stimulants:

Thermogenic stimulants are dietary supplements that work to increase metabolism, causing the body to burn more calories while boosting energy.

Synephrine (or Citrus aurantium, bitter orange): Physiological effect is similar to the banned supplement ephedra. Synephrine increases metabolic rate and caloric expenditure, thereby increasing energy. It is important to note that unlike ephedra, synephrine has no effect on heart rate or blood pressure and will not cause “jitteriness”.

Caffeine, guarana, kola nut, green tea extract: Caffeine is the most popular stimulant, often used in weight loss supplements as well as energy boosting supplements.

Caffeine can be listed under the following ingredient names: guaranine, guarana, green tea extract, kola nut, or yerba mate.

The main sources of fuel for the body are carbohydrates, one of the three macronutrients. Carbohydrates take two forms: simple sugars such as fruit juice provide quick energy; complex carbohydrates such as those found oatmeal provide sustained, lasting energy. Optimal exercise performance and endurance requires enough fuel for energy.

Bars, shakes, MRPs: Many energy bars, protein shakes and meal replacements provide carbohydrates and protein for quick or lasting energy. Products with simple carbohydrates and minimal protein are best for providing quick energy for short bursts of intense activity. Products with simple and complex carbohydrates and 15+ grams of protein per serving will provide more prolonged energy for endurance activities.
