Transparent Labs RawSeries L-Citrulline Malate 2:1
RawSeries L-Citrulline Malate 2:1 is another member of Transparent Labs’ popular RawSeries of pre-exercise dietary supplements targeting the needs of serious strength trainers who want to improve exercise performance while reducing post-exercise muscle stiffness and soreness.
L-Citrulline helps accomplish this by supporting the increase in the body’s production of nitrous oxide in response to exercise.
What is L-Citrulline Malate?
L-Citrulline is a non-essential amino acid, which means that the body can produce this substance from other compounds that are taken into the body as a part of normal nutritional intake. L-Citrulline is found in highest concentration in watermelon and, in lesser concentrations, in other members of the mellon family.
In the human body, nitrous oxide acts to dilate the smaller arteries and capillaries and thus to increase blood flow into the body’s tissues and then remove carbon dioxide or other waste products. Since no dietary supplement can provide nitrous oxide directly, they provide the precursor (“starter”) compounds from which nitrous oxide can be made.
The immediate precursor of nitrous oxide production are the amino acids L-Arginine and L-Ornithine, and the immediate precursor of l-arginine and L-Ornithine is L-Citrulline. When L-Citrulline is present in the bloodstream, it is broken down in the kidneys into l-arginine. L-Citrulline thus supplies the substance that is used to make the substance that is broken down into nitrous oxide. Malate is simply malic acid, which is bonded to to L-Citrulline to facilitate its absorption into the bloodstream by the intestines.
Most potential users of L-Citrulline might ask the obvious question “If L-Arginine and L-Ornithine are the substances that create nitrous oxide, why do I need this L-Citrulline stuff?” The answer is simply that L-Citrulline Malate is much easier on the user’s digestive system that either L-Arginine or L-Ornithine, both of which can cause diarrhea and electrolyte loss at dosages above 3 grams.
Researchers in exercise physiology have produced interesting laboratory data suggesting that the presence of extra citrulline in the diet can lead to the production of nitrous oxide during periods of heavy muscle use such as that associated with strength training.
Prior to its use as a dietary supplement in strength training L-Citrulline was, and still is, used in the treatment of mild to moderate hypertension (high blood pressure) and as a nutritional supplement in those with decreased food absorption due to intestinal or bowel surgery, or damage to the intestine that may occur during radiation therapy for some forms of cancer. Although there have been claims that L-Citrulline can mimic the effects of prescription medications used in the treatment of erectile dysfunction, most evidence indicates that the prescription medications (e.g. Viagra and Cialis) are more effective in that condition although RawSeries supplements may serve to enhance or augment these medications.
What’s in RawSeries L-Citrulline Malate 2:1?
Transparent Labs RawSeries L-Citrulline Malate contains only L-Citrulline Malate powder that is made to some of the strictest standards in the dietary supplement industry. The recommended dietary supplement dose for strength training is 6 grams (2 scoops) in 8 to 12 ounces of water or juice, to be taken 30 minutes prior to a workout session.
L-Citrulline Malate 2:1 is fully compatible with other products in the Transparent Labs RawSeries line of pre-workout supplements. Although it is possible to see benefits from a single dose of L-Citrulline Malate, the product should be used daily with meals but with half the amount (3 grams) used for pre-exercise supplementation.
From a purely physiologic sense, this would make sense because the l-arginine used to produce nitrous oxide would be quickly exhausted during exercise leaving none to deal with the post-exercise waste products of metabolism.
Many strength trainers and power lifters have reported that L-Citrulline has had a positive impact on their training programs by reducing both their between-reps rest periods as well as decreasing the amount of muscle stiffness and/or soreness that they had felt on the days after a hard workout.
Since these reports are consistent with the available scientific evidence, there is little reason to doubt the truthfulness of these first-person reports.
Transparent Labs has a well-deserved reputation for delivering quality products in all its product lines, with its RawSeries being no exception.
RawSeries L-Citrulline Malate 2:1, like all other Transparent Labs products, lives up to the great reputation of its sister products and users of this product can expect to receive nothing less than a first class pre-workout nutritional supplement.
Pros and Cons
In addition to the qualities already mentioned in this article, Transparent Labs’ RawSeries L-Citrulline Malate 2:1 has the advantage of being a purely natural product that metabolizes into substances that are always present in the body and thus RawSeries L-Citrulline Malate 2:1 can be used as a training and performance enhancer without worrying about false-positive results on pre- or post-competition drug screens.
On the downside RawSeries L-Citrulline Malate 2:1, once dissolved in water or juice, becomes a hypertonic solution. Hypertonic solutions are those whose chemical constituents exist in a higher concentration than those of the body. When a hypertonic solution is introduced into the small intestine, it will begin to draw fluids from the bloodstream into the intestine.
This can lead to a series of unpleasant symptoms such as abdominal cramping, nausea, electrolyte loss, and diarrhea. Fortunately, such symptoms are relatively uncommon and the risks of their occurrence can be minimized by taking the supplement with food or by beginning with smaller portions (e.g. 1 scoop instead of 2 in 12 ounces of juice) for a few days before moving on to a full, recommended dose.
Most powdered dietary supplements are not exactly the most pleasant-tasting things you’ve ever tasted. In this respect RawSeries L-Citrulline Malate 2:1 is surprising in that not only does it mix well with water or anything else you might choose.
And since it is a Transparent Labs product, it mixes in quite well with any of their other product lines without forming those annoying lumps that can be such a pain to dissolve when mixing different supplement products.
Transparent Labs has always had a great reputation when it comes to product value, and RawSeries L-Citrulline Malate 2:1 is no exception. In addition to their already low price, ordering from their web site will usually get you another discount on top of the value that you’ve come to expect from Transparent Labs.
Transparent Labs RawSeries L-Citrulline Malate 2:1 is a great way to add the benefits of nitrous oxide to your pre-workout supplement drinks. In addition to its reputation that comes from being a product of a first-class company, its cost per unit is among the best in the industry. You definitely need to add this supplement to your training meals today!
