Sustained Energy and Perpetuem

I was reading the difference between the two. It says Perpetuem has lyso-lecithin fat. What is that and what benefits?

Hi Wayne,

The fatty acids (lyso-lecithin) in Perpetuem basically encourages your body to use its own stored fats for fuel on endurance events and helps reduce the hunger feeling making it more satisfying on long distance events. Perpetuem is the new version of Sustained Energy that some people prefer on endurance events because of fatty acids that work so well to reduce hunger and make it a more concentrated (less scoops needed) more efficient fuel for ultra distances. Some people doing higher intensity prefer Sustained Energy because they find it to digest a little easier lacking the fatty acids. Either product is a great choice for endurance efforts and it boils down to personal preference which one you go with. I personally am a Perpetuem guy and use it all the time but I'd encourage you to experiment with both and determine which works best for you.

A little technical information about the two products can be found in The Hammer Nutrition Fuels, What They Are and How to Use Them http://www.hammernutrition.com/knowledg ... .1252.html
Under the section Comparing Sustained Energy and Perpetuem:
Sustained Energy is neutrally (a.k.a. “plain”) flavored. Perpetuem is available in three options: an orange–vanilla "Dreamsicle" flavor, a caffeinated caffe latte flavor (12.5 mg of caffeine per scoop), and in an unflavored/plain version.
Perpetuem contains lyso–lecithin fat, whereas Sustained Energy does not.
Perpetuem contains tribasic sodium phosphate, which is a tremendous lactic acid buffer. Sustained Energy does not contain this nutrient.
Both fuels contain l–carnosine (an antioxidant that also buffers lactic acid), l–carnitine (to promote fatty acid utilization), and chromium polynicotinate (to stabilize blood sugar levels).

Bottom line: With Sustained Energy and Perpetuem, you have two great long distance fuel choices. When exercise goes beyond about two hours, you can use either product as your primary or sole fuel, in any combination with each other or any other Hammer Nutrition fuel.

That said, we have noted that Sustained Energy may be the ideal fuel choice when endurance exercise intensity is at a higher level (approximately 70–85% MHR), whereas Perpetuem may be a more attractive choice the longer the athlete goes and when exercise intensity is at a more aerobic pace (under 70% MHR). Additionally, over the years we have noted that Sustained Energy may be the ideal choice for very lean athletes (the “high metabolizer/hyper–metabolic” types), while Perpetuem—with its added healthy fat component—may be the ideal choice for athletes with a naturally higher body fat percentage. The rationale for this suggestion is that athletes with a higher body fat percentage have a greater volume of calories available from body fat stores, which the lyso–lecithin component of Perpetuem may effectively assist in accessing for use as energy.

Again though, because the applications for Sustained Energy and Perpetuem are identical, either fuel can be used as the primary–to–sole fuel during prolonged bouts of exercise. Test each product in your long–duration workouts, under a variety of conditions, to find which product works best for you!

I have also some additional information from Dr. Misner who developed Perptuem and the science behind the lyso-lecithin:

Carbohydrates have an affinity for protein in time and space. When they react in any kind of moisture they change structure sensitivity toward staleness or what scientists commonly call "retrogradation". The lower the maltodextrin's dextrose equivalence (D.E.), the more likely the longer chain lengths will degrade or crystallize. Greater enzyme and fluid quantity-volume is necessary then to calorically convert stalemated-degraded carbohydrate substrates. In the absence of enzyme or fluid availability, such as that found in the depleted endurance athlete during exercise training or events, caloric transformation may be suspended or delayed from the energy cycle. A maltodextrin-monoglyceride complex is formed when the monoglyceride's long hydrophobic fatty acid chain is inserted into the middle of a maltodextrin helix. This action delays long-chain carbohydrate retrogradation in the presence of amino acid substrates. Enzymatic hydrolysis of lecithin produces Lysolecithins in which the middle fatty acid is removed. This allows the lecithin's hydrophobic remaining fatty acid to be drawn into the helix of the carbohydrate for inhibition of retrograded staling. It has been shown by scanning calorimetry research that hydrolyzed lysophilized Soy Lecithin effectively complexes with starch from wheat sources. When a lipid-lysolecithin, with its middle fatty acid removed, is agreeably adjoined or "coated" upon in a gel-formatted starch (MALTODEXTRIN), it will actively retard the release of free amylose, which will interact with the available proteins, resulting in retrograded staling reaction in time. Such a fuel source should hypothetically enhance prolonged performance in nearly "perpetual" fashion.

I hope that answers your question, please let me know if you have additional questions.
