Proprietary Nitraflex Nutrient Partitioning Blend
Also known as: Nitraflex Nutrient Partitioning Blend, GAT Nitraflex Pre-workout Blend, Proprietary Nitraflex Nutrient Partitioning Blend
Overview
The Proprietary Nitraflex Nutrient Partitioning Blend is a key component of the GAT Nitraflex pre-workout supplement, designed to enhance exercise performance, energy, focus, and muscle pumps. While its exact chemical composition and ingredient quantities are undisclosed due to its proprietary nature, it is known to contain a synergistic mix of nitric oxide (NO) precursors (e.g., citrulline, arginine), stimulants (caffeine), and other bioactive compounds like beta-alanine, resveratrol, pterostilbene, and calcium fructopyranose borate (CFB). Ingredients like citrulline and arginine are naturally occurring amino acids, while resveratrol and pterostilbene are polyphenols. The blend is primarily used by healthy adults engaging in resistance or high-intensity training to improve vasodilation, reduce fatigue, and increase central nervous system stimulation. Although individual ingredients have extensive research, the blend itself lacks direct peer-reviewed clinical trials, with evidence extrapolated from its components.
Benefits
The blend's benefits are derived from its individual components. Nitric oxide precursors like citrulline and arginine are known to increase NO production, leading to vasodilation, improved muscle blood flow, and enhanced muscle pumps and endurance. Meta-analyses on nitrate supplementation, a related NO pathway, show small but statistically significant improvements in exercise performance (standardized mean difference ~0.18, p<0.001). Beta-alanine, present at 1,600 mg per serving, improves high-intensity exercise performance by buffering muscle acidity and delaying fatigue, with moderate effect sizes. Caffeine, at a high dose of 325 mg per serving, is a well-established ergogenic aid that significantly increases energy, focus, and metabolic rate, with doses around 3-6 mg/kg body weight improving endurance and cognitive focus. Resveratrol and pterostilbene offer antioxidant properties, though their direct acute impact on exercise performance within this blend is less clear. Calcium fructopyranose borate (CFB) is marketed for testosterone enhancement, but robust clinical evidence for this claim is lacking. The blend is most beneficial for healthy adults in resistance or high-intensity training, with acute effects from caffeine and NO precursors appearing within 30-90 minutes, while beta-alanine requires chronic supplementation for carnosine buildup.
How it works
The Proprietary Nitraflex Nutrient Partitioning Blend operates through multiple synergistic mechanisms. Nitric oxide (NO) precursors, such as citrulline and arginine, increase NO synthesis, leading to vasodilation and enhanced blood flow to working muscles, which improves nutrient and oxygen delivery and waste removal. Beta-alanine increases muscle carnosine levels, which acts as an intracellular buffer for hydrogen ions, thereby delaying the onset of muscular fatigue during high-intensity exercise. Caffeine, a potent central nervous system stimulant, primarily works by blocking adenosine receptors, leading to increased neuronal activity, heightened alertness, improved focus, and a reduction in perceived exertion. These actions collectively enhance cardiovascular function, muscular endurance, and neurological drive during physical activity.
Side effects
While generally safe for healthy adults at recommended doses, the Proprietary Nitraflex Nutrient Partitioning Blend carries potential side effects, primarily due to its high caffeine content (325 mg per serving) and beta-alanine. The most common side effect is tingling or paresthesia, caused by beta-alanine, which is typically harmless and subsides with continued use. Caffeine can lead to jitteriness, increased heart rate, anxiety, insomnia, and gastrointestinal discomfort, especially in caffeine-sensitive individuals. Uncommon side effects may include headache. Rare but more severe cardiovascular events are possible, particularly in predisposed individuals. The blend should be avoided by pregnant or breastfeeding women, individuals with pre-existing cardiovascular conditions (e.g., hypertension, arrhythmias) without medical consultation, and those sensitive to stimulants. Caffeine can interact with stimulant medications and blood pressure drugs. Resveratrol may affect cytochrome P450 enzymes, potentially altering the metabolism of certain medications. Not recommended for children or adolescents.
Dosage
The Proprietary Nitraflex Nutrient Partitioning Blend is typically consumed as a single serving of the Nitraflex pre-workout powder. While the exact quantities of most ingredients are proprietary, it is known to contain 325 mg of caffeine and 1,600 mg of beta-alanine per serving. For optimal acute effects from caffeine and nitric oxide precursors, it should be taken 30-60 minutes before exercise. Beta-alanine, however, requires chronic daily dosing over several weeks to build up muscle carnosine levels for its full benefits. The minimum effective dose for caffeine is around 3 mg/kg body weight, and for beta-alanine, it's typically 2-5 grams per day. The maximum safe dose for caffeine in healthy adults is generally considered to be 400 mg per day, and for beta-alanine, up to 6.4 grams per day. It is consumed in powder form, mixed with water. Food intake may delay absorption, so it's often recommended on an empty stomach.
FAQs
Is the proprietary blend effective?
While the blend itself lacks direct clinical trials, it contains several ingredients (caffeine, beta-alanine, citrulline) with strong evidence for improving exercise performance, energy, and focus. Its effectiveness is based on the known benefits of its individual components.
Is it safe?
Generally safe for healthy adults at recommended doses. However, its high caffeine content (325 mg) may cause side effects like jitters or increased heart rate in sensitive individuals. Consult a healthcare professional if you have pre-existing conditions.
When should I take it?
For optimal acute effects from caffeine and nitric oxide precursors, take one serving 30-60 minutes before your workout. Beta-alanine's benefits accumulate over time, so consistent daily use is key.
How soon will I see results?
You can expect acute effects like increased energy, focus, and muscle pump from caffeine and NO precursors within 30-90 minutes. Benefits from beta-alanine, such as reduced fatigue, typically require several weeks of consistent use to become noticeable.
Does it enhance testosterone?
The blend contains calcium fructopyranose borate (CFB), which is marketed for testosterone enhancement. However, robust clinical evidence from high-quality studies to support this specific claim for CFB in humans is currently lacking.
Research Sources
- https://pmc.ncbi.nlm.nih.gov/articles/PMC7494956/ – This systematic review and meta-analysis of 25 randomized controlled trials concluded that nitrate supplementation significantly improves exercise performance with a small but statistically significant effect size (SMD ~0.18, p<0.001). The study highlights the ergogenic potential of nitrate, a key component in nitric oxide pathways, despite some heterogeneity in study designs.
- https://pubmed.ncbi.nlm.nih.gov/35055584/ – This systematic review investigated the effects of nitrate supplementation on explosive performance across 18 studies. It found mixed results, with some studies showing improvements in sprint and resistance exercise power, while others did not. The review suggests that while promising, more research with standardized protocols is needed to confirm the benefits of nitrate for explosive movements.
