intenseFX Quick Release Energy Tablet

intenseFX™ Quick Release Energy Tablets combine caffeine, amino acids and B-vitamins to provide the long-lasting physical and mental energy you and your lifestyle demand. Coffee and soft drinks might wake you up, but they don’t support your mental focus. intenseFX™ supports your body’s own energy systems in providing long-term, sustainable performance you can count on.*

intenseFX™ Quick Release Energy Tablets provide much-needed fuel and promote mental focus without a major crash afterward. Huge amounts of sugar in mass-marketed energy drinks might bring a big rush but only with a slowdown that has you falling twice as hard. This definitely defeats the purpose of using them for energy. They also rob your focus and add empty calories that nobody needs. While energy shot formulas might spare you the sugar, they still can’t deliver the pocket-sized, quick-dissolving convenience that delivers intenseFX™ in a flash — any time you need it!*

The convenience and potency of intenseFX™ Quick Release Energy Tablets make them a practical solution anytime, anywhere. For school, work or play, intenseFX™ Quick Release Energy Tablets are great tasting, quick dissolving and fast acting, delivering sustained, natural energy whenever you need it with zero sugar, calories or crashing. Life moves fast — and intenseFX™ Quick Release Energy Tablets can help you move faster.*  


Caffeine 75 mg
Caffeine promotes focus and alertness, and stimulates the central nervous system. It also  support the breakdown sugars and fats in the body, promoting a mild thermogenic effect.

Thiamin (Vitamin B1) 1.5 mg

Thiamin supports a healthy nervous system, and promotes the production of the neurotransmitters acetylcholine and gamma-aminobutyric acid (GABA), which both regulate neural excitability. Thiamin supports normal carbohydrate metabolism and nerve function. It increases energy and helps promote mental clarity.

Riboflavin 5-Phosphate (Vitamin B2) 1.7 mg
Vitamin B2 promotes the conversion of food into energy. Vitamin B2 supports the breakdown of fats, while functioning as a cofactor or helper in activating B6 and folic acid. Vitamin B2 is water-soluble and cannot be stored by the body except in insignificant amounts; thus, it must be replenished daily.

Pyridoxine HCl (Vitamin B6) 3 mg

Vitamin B6 has been recommended as a nutrient to enhance mental function, as it supports the normal synthesis of neurotransmitters in brain and peripheral nerve cells. Some athletic supplements include vitamin B6 because it promotes the conversion of glycogen to glucose for energy in muscle tissue. Vitamin B6 is a co-factor that promotes protein and amino acid metabolism and helps maintain proper fluid balance. It also assists in the maintenance of healthy red and white blood cells. Vitamin B6 should be taken as a part of a complex of other B-vitamins for best results.

Vitamin B12 (Cyanocobalamin) 1 mg

Vitamin B12 helps maintain optimum energy levels, as it plays a vital role in the Krebs energy cycle. It also promotes concentration. It is essential that vegetarians consume a vitamin B12 supplement to maintain optimal health. Vitamin B12, when ingested, is stored in the liver and other tissues for later use. The synthetic form of vitamin B12, cyanocobalamin, is not derived from either plants or animals and is integral in the maintenance of normal functioning body cells, especially those of the nervous system (protecting the sheaths of nerve cells), bone marrow and intestinal tract. These tissues are the first to exhibit signs of vitamin B12 depletion.

Taurine 30 mg

Taurine is important in the hydration of the body and gives an energy boost by promoting the cells’ nutrient uptake, as well as enhancing physical reaction time. Further, it promotes mental alertness and supports the ability to concentrate. It is classified as an essential amino acid, and supports micelle formation and fat absorption. It is found in high amounts in the brain, retina, myocardium, skeletal and smooth muscle, platelets and neutrophils. It is plentiful in the fluids of muscle, lungs and nerve tissue. Dietary taurine mainly comes from animal food sources. Taurine is also present in plant food sources like seaweed.

Arginine 20 mg
L-arginine supplements may prove to be a good way to maintain healthy circulation to the heart and blood vessels, while promoting the delivery of oxygen and other important nutrients to the brain. Arginine is an amino acid found in many foods such as dairy products, meat, poultry, fish, nuts and chocolate. It supports several important processes in the body.

Love it!

By MikeM

Comments about intenseFX Quick Release Energy Tablet:

I recently started a manually intensive job, and about halfway through I find myself feeling sluggish. I take a tablet, and not only finish the day strong, but have more of a bounce in my step at the end than I did when I started.

Love this product. Whenever I notice that I'm starting to yawn at work, I take a tablet and I realize that after I'm no longer yawning but I don't feel worked up or jittery- just calm and awake. Thanks for such a great product!

It dies exactly what it says. I feel the energy quickly and it's a great pick me up after lunch, right before working out or for those late nights. I really like them.

As a mother of 2 young children, the extra boost in the afternoon or after a night of not much sleep, the Intense FX gives me that extra little boost without the jitters! It is a great boost before work outs as well!
