DAILY PUMP 2nd Edition

Electrolytes

Our bodies get pushed to their limits every single day and are expected to perform at a high level through a large variety of activities and events. Of these are athletic events, and in this context, fitness. No matter what, our bodies are in a constant period of either losing fluids and regaining fluids lost. These fluids offer a wide variety of essential benefits including aiding in muscle contraction and relaxation, balancing blood pH, regulating blood pressure, and controlling overall cellular fluid balance. The common electrolytes sodium and potassium work synergistically to provide a balanced fluid level within the body to maximize performance. ARN Daily Pump is formulated with an adequate blend of these electrolytes to help replace what is lost through intense training to allow for optimal functioning and performance from session to session.

Citrulline

Citrulline is a non-essential, non-protein amino acid that forms during the urea cycle and forms ornithine when combined with carbon dioxide. Citrulline is also a critical source of endogenous (natural) arginine, as it is rapidly and efficiently converted to arginine in the vascular endothelium and other tissues.

Citrulline’s benefits have been shown to be greater than its parent compound. While arginine undergoes direct hepatic (liver) metabolism through the enzyme arginase, citrulline bypasses hepatic metabolism entirely and it is delivered straight to the bloodstream. The result is that gut absorption and plasma (blood) bioavailability studies comparing citrulline and arginine have shown two things. First, that citrulline is less readily destroyed and has greater absorption than arginine. Second, that citrulline supplementation increases arginine levels more effectively than arginine supplementation itself.

This translates to promising results. For example, animal studies show a significant increase in anaerobic performance at a 250mg/kg/day serving of citrulline, while studies in humans implicate citrulline in both aerobic and anaerobic performance increases. As a critical part of the urea cycle, citrulline’s performance benefits are thought to be a result of its role in ammonia clearance. Citrulline is implicated in reducing the oxygen cost of muscle processes, along with increasing the rate of post-exercise ATP and phosphocreatine replenishment. As ATP and phosphocreatine are the body’s ‘exercise fuel,’ this may result in citrulline delaying time to exhaustion in aerobic and anaerobic exercise.

Beta Alanine

Carnosine is a bit of a misunderstood compound. We know that it is crucial for muscle function, and that dietary sources of carnosine are essential, but we don’t know precisely how it works. Moreover, for decades, we had no idea how to increase intramuscular concentrations of carnosine, as exogenous sources degraded in the body so quickly that it seemed to be effectively useless.

Enter beta-alanine. Simply a different iteration of one of the amino acids that comprises carnosine itself (alanine), beta-alanine has proven to be the most effective means of significantly increasing intramuscular concentrations of carnosine – and therefore of promoting all of carnosine’s various beneficial effects on muscle performance. If that weren’t enough, beta-alanine has also demonstrated beneficial physiological effects independent of its parent compound. In order to understand why, though, we need to first understand some of the basics behind carnosine itself.

Carnosine, a cytoplasmic dipeptide synthesized from the precursors L-histidine and l-alanine, is present in high concentrations in skeletal muscle and plays a pivotal role as a “chemical buffer” in myocytes (muscle cells). It has long been known that carnosine concentrations are highest in glycolytic muscle fibers (explosive) rather than oxidative muscle fibers (endurance) and thus long hypothesized that this amino acid is required for sustained performance during supramaximal exercise. Recent research demonstrates that carnosine exerts its physiological effects in long hypoxic (low oxygen) drives by functioning as a high-capacity pH buffer in skeletal muscle, preventing the pH ratio of plasma from dropping too low – and therefore preventing crucial pH-dependent processes such as protein synthesis from being inhibited by acidosis.

Despite its critical role in skeletal muscle anaerobic performance, intramyocellular synthesis of carnosine is rate-limited by the availability of l-alanine. Unfortunately, the majority of literature demonstrates that attempting to increase intramuscular levels of carnosine via either direct carnosine or alanine supplementation is largely ineffective due to carnosine/alanine pharmacokinetics. Enter beta-alanine. Research with beta-alanine demonstrates consistent and dose-dependent increases to intramuscular carnosine concentrations with beta-alanine supplementation, with certain studies showing an increase of 40-60% with chronic administration. These same writings reveal a synergistic effect of exercise on beta-alanine supplementation, whereby the muscles adaptive changes associated with resistance training promote further intramuscular carnosine production in response to beta-alanine supplementation.

In simpler terms, this essentially means that beta-alanine is a dietary supplement that promotes its own effects in combination with exercise. As you exercise, you simultaneously intensify beta-alanine’s physiological actions – both directly, as well as in the production of intramuscular carnosine. Once ingested, beta-alanine’s exercise-specific beneficial activity is well-established. Elevation of intramuscular carnosine content via beta-alanine supplementation has been shown to improve performance in the following ways.

• Both acute and chronic increases in total work capacity, measured by total volume during exercise sessions.
• Highly significant increases to TTE (total time to exhaustion), one of the most accurate and comprehensive measures of endurance. In various trials, beta-alanine supplementation has been shown to increase TTE by upwards of 20%.
• Increases to total muscle power output in both acute and chronic trials, suggesting that beta-alanine’s most significant benefit is to those engaging in power-dependent resistance training.

In total, a significant body of research exists to suggest that beta-alanine may significantly increase muscle power output, strength, training volume and output, overall performance in hypoxic (oxygen-deprived) conditions and peak VO2 max (oxygen holding capacity).

These myriad benefits make beta-alanine both one of the most-studied, and most well-rounded dietary supplements. Beta-alanine not only has direct, actionable physiological effects, but also promotes critical muscle physiologic adaptations that promote its own effects.

Betaine Nitrate (NO3-T®)

Betaine (trimethylglycine) is found naturally in most living organisms. It is well known to protect non-mammalian animal life in conditions of osmotic stress (a rapid change in the amount of solute surrounding a cell), in addition to functioning as an osmolyte in mammalian (including human) tissues\. Betaine is formed in cells as an oxidation product of choline and can be obtained in the diet from foods such as spinach and beets.

Though data on betaine is limited, and recent, the available literature suggests that this compound may have effects in a number of areas. Studies on betaine using servings as little as 1.25g/day and up to 5g/day for up to 14 days have shown promising results. In one study, a 2.5g/day serving was found to enhance endurance and total repetition volume for the squat, bench press, and jump squat in in healthy-exercised trained adults. A similar study using the same serving found that betaine use increased peak power and maximum peak power, along with force and the maintenance of both force and power in healthy, exercise-trained subjects.

Perhaps more interesting, however, is a study which examined betaine’s effect on the endocrine system. This study revealed that betaine may exert an effect on several endocrine processes given the proper conditions, causing the authors to hypothesize that long(er) term betaine supplementation may increase the hypertrophic response to resistance training.

Pairing betaine with the patented nitrate (N03-T®) enhances nitric oxide production via the nitrate-nitrite pathway. Organic nitrate esters have a direct relaxant effect on vascular smooth muscles through non-nitric oxide synthase pathways, being directly converted first to nitrites and then to nitric oxide itself. (With attendant increases to guanylyl cyclase and then cyclic guanosine monophosphate (cGMP), which relax the vasculature.) Pairing both nitric oxide synthase and non-nitric oxide synthase-dependent mechanisms of actions theoretically enhances total NO production, given that rate-limiting enzymatic pathways in either mechanism do not determine total NO production.

In an absolute sense, both inorganic and organic nitrates also possess benefits beyond a secondary NO-production pathway. Studies in athletes have demonstrated that nitrate ingestion prior to both aerobic and anaerobic exercise meaningfully increases both delay to fatigue and total work capacity – likely a consequence of nitrate’s activation in hypoxic (oxygen-deprived tissues). Nitrate effectively reduces the oxygen cost of muscular activity, making contractions more efficient.

Alpha GPC

Of the known choline pro-drugs or precursors, Alpha GPC appears to have exert the greatest influence on circulating choline levels. Choline is an essential nutrient involved in numerous metabolic pathways, including DNA regulation and repair, protein function, and metabolism. Perhaps most importantly, the critical neurotransmitter acetylcholine is produced directly from free choline via cholinergic neurons. Acetylcholine is then responsible for several functions itself, most crucially as the compound which induces muscular contraction, and as the neuromodulator partially responsible for modulating risk/reward, arousal, and enhancing memory.

Choline’s essential role as a substrate for acetylcholine, and therefore brain development, is well documented in animal models. These studies demonstrate that levels of free maternal choline have a direct and fundamental impact on prenatal brain development, with the enhancements or deficits lasting into adulthood. Choline’s enhancing effect is particularly prominent in the hippocampus. In humans, the hippocampus is primarily involved in the consolidation of memory (taking short, episodic memory and translating it into long-term memory) and the learning of new information. Acetylcholine is a critical component in these processes, as mentioned above, and choline may therefore play a potential role in these processes as well by providing the substrate for acetylcholine synthesis.

Whether through these, or other independent mechanisms, a recent trial using Alpha GPC demonstrated a statistically significant increase to power output. In a placebo-controlled, double-blind, randomized trial, 14 healthy volunteers, split into an Alpha GPC or placebo group, were tested on various exercises. In comparison to the placebo group, the Alpha GPC group experienced a 14% increase to bench press. The researchers hypothesize that the peak power increase was the result of a substantial acute increase to growth hormone, one of the observed effects of Alpha GPC supplementation.

Senactiv® (Panax notoginseng (root) and Rosa roxburghii (fruit)) Extracts

Senactiv®, derived from extracts of Panax notoginseng and Rosa roxburghii, has been shown to act in a few pathways to reenergize and rejuvenate cells within the body that take a beating on a daily basis. Ultimately this product falls within a category known as senolytics, or compounds that primarily work to induce cell death. This may not sound ideal as we need our cells to function, but the key is to ensure that these compounds are working on the right kinds of cells. The human body does contain many senescent cells, which are old cells and can be deteriorating. How these senolytics work to promote health is by speeding up the breakdown of these older cells as well as encouraging the grow of new, vibrant cells. The other benefit of Senactiv® and its ingredients is its ability to protect against muscle damage. Ginseng in particular has been shown to help reduce the proinflammatory state that is associated with rigorous training. Where this is going to benefit is to reduce inflammation and jumpstart the recovery process of torn down muscle fibers so these cells can begin to scar and grow stronger. The other benefit that ginseng has been able to show is it has been shown to improve VO2 max by about 20% when compared to a control group in studies. This improvement can significantly improve oxygen uptake to increase delivery to muscle cells for the ability to push harder and longer. 

On another angle of recovery, Senactiv® has been shown to improve the rate of glycogen storage after exercise. When glycogen can be stored efficiently post exercise it has the ability to attenuate the structural damage associated with training by allowing those carbohydrates and sugars going towards recovery.
