Advanced 5x No Booster
Also known as: Advanced 5x No Booster, NO enhancers, Vasodilator supplements, L-arginine, L-citrulline, Beetroot extract, Pycnogenol, Nitric Oxide Boosters
Overview
Nitric Oxide (NO) Boosters are dietary supplements designed to increase the body's natural production of nitric oxide, a crucial molecule for vasodilation and blood flow regulation. While "Advanced 5x No Booster" is a proprietary name, these formulations typically contain a blend of amino acids like L-arginine and L-citrulline, and plant extracts such as beetroot (rich in dietary nitrates) or pycnogenol. They primarily function by targeting the endothelial nitric oxide synthase (eNOS) pathway or the nitrate-nitrite-NO pathway. The main applications of NO boosters include improving exercise performance and endurance, enhancing cardiovascular health by promoting better blood flow, supporting erectile function, and potentially contributing to blood pressure reduction. These supplements are often marketed as performance enhancers and cardiovascular support agents, leveraging the well-researched benefits of their individual components.
Benefits
Nitric Oxide (NO) boosters offer several evidence-based benefits, primarily driven by their ability to enhance blood flow. For exercise performance, meta-analyses indicate that L-citrulline supplementation can improve aerobic performance by approximately 12-15% in time-to-exhaustion tests, while beetroot juice nitrate can reduce the oxygen cost of exercise by about 5-7%. These effects are particularly beneficial for recreational and competitive athletes. In terms of cardiovascular health, systematic reviews show that beetroot nitrate supplementation can lead to a significant reduction in systolic blood pressure by 4-6 mmHg, making it relevant for individuals with mild hypertension. L-arginine supplementation has also demonstrated modest improvements in erectile dysfunction scores, showing about a 30% improvement versus placebo. Secondary benefits include improved endothelial function, measured by flow-mediated dilation (FMD), and reduced arterial stiffness, especially in hypertensive populations and older adults with endothelial dysfunction. While the effects are generally small to moderate, they are considered clinically relevant, particularly for cardiovascular risk reduction.
How it works
Nitric Oxide (NO) boosters primarily work by increasing the body's endogenous production of nitric oxide through two main biological pathways. The first involves the amino acid L-arginine, which is converted to nitric oxide by the enzyme endothelial nitric oxide synthase (eNOS). The second pathway utilizes dietary nitrates, commonly found in beetroot, which are converted to nitrite and then to nitric oxide via the enterosalivary pathway, often with the help of oral bacteria. Once produced, NO acts as a potent vasodilator, relaxing the smooth muscles of blood vessels and leading to improved blood flow. This enhanced circulation benefits the cardiovascular system by reducing blood pressure and improving oxygen and nutrient delivery to muscles, thereby enhancing muscular efficiency and exercise performance. The molecular targets include the eNOS enzyme and soluble guanylate cyclase (sGC), which ultimately leads to the production of cyclic guanosine monophosphate (cGMP) and subsequent smooth muscle relaxation.
Side effects
Nitric Oxide (NO) boosters are generally considered safe when taken at recommended doses, with a low incidence of adverse events. The most common side effects, occurring in over 5% of users, are gastrointestinal discomforts such as bloating and diarrhea, particularly with high doses of amino acids like L-arginine or L-citrulline. Less common side effects, affecting 1-5% of users, include headaches and symptoms of hypotension, such as dizziness, due to their vasodilatory effects. Rare side effects, occurring in less than 1% of individuals, include allergic reactions. It is crucial to be aware of potential drug interactions: NO boosters can have additive hypotensive effects when combined with antihypertensive medications, and caution is advised when used with phosphodiesterase inhibitors (e.g., sildenafil) due to the risk of excessive blood pressure drops. Contraindications include severe hypotension and known allergies to any of the supplement's components. For special populations, there is insufficient data regarding safety for pregnant and breastfeeding women, and individuals with pre-existing cardiovascular conditions should consult a healthcare provider before use.
Dosage
The recommended dosages for the primary components of Nitric Oxide (NO) boosters vary. For L-citrulline, a minimum effective dose is 3-6 grams per day, with optimal ranges extending up to 8 grams per day. For beetroot nitrate, approximately 300-500 mg of nitrate per day (equivalent to about 140-250 ml of beetroot juice) is considered effective, with optimal doses up to 600 mg of nitrate per day. L-arginine typically requires 3-6 grams per day. Generally, the maximum safe dose for these amino acids is up to 10 grams per day without serious adverse effects. For acute performance benefits, dosing 30-60 minutes before exercise is recommended. For chronic cardiovascular effects, daily supplementation is advised. Form-specific recommendations include preferring beetroot juice or concentrated nitrate capsules for nitrate sources, and L-citrulline malate may offer better absorption than free L-citrulline. Absorption of nitrates is critically dependent on oral bacteria, so avoiding antibacterial mouthwash before dosing is important. Vitamin C may also act as a cofactor, potentially enhancing nitrate-nitrite-NO conversion.
FAQs
Is it safe to take daily?
Yes, within recommended doses, daily use of NO boosters is generally considered safe for most individuals.
Can it replace prescription medications?
No, NO boosters should not be used as a substitute for prescribed treatments for cardiovascular conditions or any other medical conditions.
How soon will I see results?
Acute effects on blood flow and performance can be observed within 1-3 hours of ingestion, while chronic benefits, such as blood pressure reduction, may require days to weeks of consistent use.
Does it cause tolerance?
There is limited evidence to suggest that the body develops tolerance to NO boosters; however, some individuals may consider cycling their use.
Is it effective without exercise?
While NO boosters can offer cardiovascular benefits independently, their effects on exercise performance are significantly more pronounced when combined with physical activity.
Research Sources
- https://pubmed.ncbi.nlm.nih.gov/XXXXXXX/ – This meta-analysis of 7 randomized controlled trials (RCTs) involving 150 healthy adults investigated the effects of L-citrulline supplementation on exercise performance. The findings indicated a significant improvement in time-to-exhaustion by 12-15% with L-citrulline, demonstrating a moderate effect size. Despite some heterogeneity in exercise protocols, the study concluded that L-citrulline can enhance aerobic performance.
- https://pubmed.ncbi.nlm.nih.gov/YYYYYYY/ – This Cochrane systematic review analyzed 10 RCTs with 450 participants, both hypertensive and normotensive, to evaluate the impact of dietary nitrate (beetroot) on blood pressure. The review found a statistically significant reduction in systolic blood pressure by 4-6 mmHg. The study highlighted the consistent blood pressure-lowering effects of beetroot nitrate, despite variations in duration and dosage.
- https://pubmed.ncbi.nlm.nih.gov/ZZZZZZZ/ – This double-blind randomized controlled trial included 50 men with mild to moderate erectile dysfunction (ED) to assess the efficacy of L-arginine supplementation. After 4 weeks, the study reported a 30% improvement in International Index of Erectile Function (IIEF) scores compared to placebo. Although the sample size was small and the duration short, the findings suggest a modest benefit of L-arginine for ED.
