Product Overview

active/sport performance pre-workout

Increase your endurance and burn more fat to get the most out of your cardio sessions! Cardio Igniter® is designed to maximize your aerobic capacity so you can run, swim, spar, train longer; and burn fat, not muscle, while doing it. So drink up, lace up, and get out there and go for miles.*

aerobic capacity booster*

performance enhancing fat burner*

improves endurance*

never do high intensity exercise without it!

Amino Shield® with ursolic acid - with ursolic acid – Amino Shield is a patent-pending anti-catabolic lean mass potentiating element, containing ursolic acid* We included Amino Shield in Cardio Igniter to help reduce muscle loss and support lean mass stimulation.*

Red Beet Juice High in Nitrates - Red beet root is naturally high in nitrates (NO3) which are believed to improve athletic performance. A study led by the University of Exeter, published in 2009 in the Journal of Applied Physiology, pointed to the benefits of NO3, concluding that they boost a cyclist's endurance. Nitrates are helpful to athletes because they quickly bring oxygen to muscles.*

Raspberry Ketones - Research suggests that raspberry ketones may have the potential to support body fat reduction by increasing norepinephrine-induced lipolysis (stored fat release).*

L-Carnitine - is a naturally occurring amino acid that plays a vital role in the metabolism of fat. It functions as a transporter of fatty acids into the mitochondria, the metabolic furnace of the cell. It has been established that an adequate supply of L-carnitine is necessary for the maintenance of good health and energy.*

Carnosyn® Beta-Alanine - Beta-alanine is an amino acid that promotes muscular energy. A study published in a 2010 issue of Medicine and Science in Sports and Exercise concluded that supplementation with beta-alanine increases muscle’s carnosine content and, therefore, total muscle buffer capacity, with the potential to improve physical performance during high-intensity exercise and to delay the onset of neuromuscular fatigue.*

Brassica Campestris - is a lipolytic stimulator, is a cruciferous vegetable that has been suggested to possess weight loss promoting effects.*

L-Tyrosine – is a precursor to dopamine, also known as the “feel-good hormone”. A recent human study showed that acute tyrosine supplementation is associated with increased endurance capacity for moderately trained subjects exercising in hotter climate.*

L-Taurine - is a non-essential sulfur-containing amino acid and plays a role in several metabolic processes, such as heart contraction and antioxidant activity. It is essential for cardiovascular function, and development and function of skeletal muscle. In an exercise study conducted with 11 men ages 18-20 and taurine supplementation, it was found that significant increases in VO(2)max, exercise time to exhaustion and maximal workload occurred.*

Caffeine – We have included caffeine in Cardio Igniter for its ability to improve aerobic performance, reduce fatigue, stimulate mental activity, induce lipolysis, and help prioritize fat as an energy source during exercise.*

Evodiamine – Evodiamine is an extract from the Tetradium family of plants. Research has suggested that evodiamine acts primarily as a thermogenic, similar to capsaicin.*

Choline Bitartrate - Choline bitartrate is a water-soluble B vitamin that is a precursor to acetylcholine, one of the crucial brain chemicals. Acetylcholine is a neurotransmitter used throughout the body; it controls muscle contraction and determines your brain speed. Research suggests that choline levels drop during exercise, and supplementing choline prior to exercise can enhance pre-workout vigor and reduce post-workout fatigue.*

Electrolytes - Are needed to maintain proper fluid balance and to optimize your energy levels so you can function at your best. We have added a unique electrolyte matrix of dipotassium phosphate, disodium phosphate, magnesium glycerophosphate, and magnesium aspartate to Cardio Igniter to help maintain a desirable electrolyte balance while exercising.*

Get the most out of your workouts by burning more fat and boosting performance.

Nothing gets 10 / 10, but it would be unfair if I don’t give this one a 10 / 10. It has been over a month I have been using this product and every time I use it, it gets better. I couldn’t believe I could run on a treadmill for 40 min at a stretch; but Cardio Igniter makes it possible. Frankly, this product has really boosted my cardio-vascular training capabilities. Now I can do the training for over 90 min and still feel energy left in me. :) Fruit Punch flavor is sooper awe (keen to try Blue Raspberry), the only thing is it leaves a medicinal after taste. Nonetheless, you would get used to it and probably would start liking it.. :) I take it thrice a week only half hour before cardio training in 16 oz chilled water. Also the added advantage is YOU LOSE WEIGHT :) 10th Aug 14 - 189 lbs 13th Sept 14 - 182 lbs

Great stuff! I used the old and the new formula (not sure the formula changed much, but the packaging did). It works! I try to incorporate a 60 minutes cardio work-out during, and I am using this product during. The first 20 minutes just fly by, and you stay very focused. The other 20 are more gruesome, but you manage to push through. I think CI gives you the extra umph! The last 20 minutes you tap into your reserves, and usually you are able to do a semi-sprint in the last 5 minutes or so. There is just this rush of energy. DON'T over do it though! I usually use a scoop and a quarter. You don't get the jitters, but anything more than - you feel the heart in the chest (rate is usually elevated over by 10-20 bpm than what it should be).

Mixing this with cold water is a must; careful with room temperature water. I hardly notice any difference in improving my cardio with this and any difference wears off after the first mile. I will not repeat this buy.

The fruit punch tastes like a pixie stick. I enjoyed the flavor quite a lot. My energy levels were through the roof on this product. I'm not sure it helped my "pump" much at all. This is still my favorite energy boost before conditioning or high-intensity workouts. This would not be my product of choice for heavy lifting days.

Perfect energy to push through a demanding workout without a crash at the end. Only con is you must take it at least 2 hours before your workout as it lasts for while in your system after your workout is ended, which in turn affects when you sleep.

Used the product for more than two years and it has worked very well for me. I take it 20 minutes before any cardio activity, and you really feel energized. It is like a slow burning fuel which aids your endurance. I strongly recommend the product without reservations.

I had the liberty of trying some samples and this is what I think.. Everything you would imagine from a pre-workout. Decent pump, decent flavor, mixes very well. I hope this helps someone!
