insights Analysis
This Nutricost Performance Nitric Oxide Booster stands out by incorporating multiple forms of both Arginine (1500mg total from Arginine AKG, L-Arginine, L-Arginine HCl) and Citrulline (750mg total from L-Citrulline Malate, L-Citrulline). This higher combined dosage per serving, along with the inclusion of preferred forms like L-Citrulline Malate and Arginine AKG, suggests a more robust and effective approach to nitric oxide production compared to basic single-form supplements. Online reviews frequently highlight noticeable improvements in 'pumps' and exercise performance, underscoring its efficacy for fitness-oriented users.
- Contains multiple forms of both L-Arginine (AKG, free-form, HCl) and L-Citrulline (Malate, free-form), potentially offering varied absorption and sustained nitric oxide benefits.
- The combined dosage of Arginine (1500mg) and Citrulline (750mg) per serving is higher than many basic supplements, indicating greater potential efficacy.
- The inclusion of L-Citrulline Malate is a significant advantage, as it is widely regarded as more effective for performance enhancement due to the added benefits of malic acid.
- The price per serving is higher than basic Arginine/Citrulline products, making it a larger investment for daily supplementation.
- While dosages are improved, they are still below the very high gram dosages (e.g., 6-8g Citrulline Malate) sometimes recommended for maximal acute performance benefits in serious athletes.
- The specific benefits of combining multiple Arginine forms beyond total dosage are not always definitively proven in all studies, potentially leading to unnecessary complexity.
- Individuals with pre-existing heart conditions or those on medications for blood pressure (e.g., nitrates) should consult a healthcare professional before use, as nitric oxide boosters can affect blood pressure.
- Some users may experience mild digestive upset, especially with higher dosages or specific forms like Arginine AKG.

bolt Effectiveness for goals
Yes, L-Citrulline supplementation can lead to higher and more sustained plasma L-Arginine levels than Arginine supplementation alone. This is because Citrulline bypasses intestinal and liver metabolism, being efficiently converted to Arginine in the kidneys. This indirect pathway can more effectively increase nitric oxide production.
L-Citrulline is often considered more effective at increasing sustained L-Arginine and nitric oxide levels in the body than L-Arginine itself. This is because L-Citrulline bypasses significant metabolism in the gut and liver, converting to L-Arginine more efficiently in the kidneys. This leads to a more pronounced and prolonged increase in circulating L-Arginine.
L-Citrulline is converted to L-Arginine in the kidneys, which then increases nitric oxide production. This can lead to enhanced blood flow to muscles during exercise, potentially reducing fatigue and improving endurance. It's particularly studied for high-intensity activities and resistance training.
Combining L-Arginine and L-Citrulline may offer enhanced and more sustained nitric oxide production. L-Citrulline can recycle back into L-Arginine, creating a continuous supply for nitric oxide synthesis. This combined approach could potentially lead to greater and longer-lasting effects on blood flow compared to taking either supplement alone.
L-Citrulline is converted to L-Arginine in the body, leading to increased nitric oxide production. This can help improve blood flow to muscles during exercise, potentially enhancing endurance and reducing fatigue. Studies have shown L-Citrulline to be effective in improving performance in both aerobic and anaerobic exercises.
schedule Dosage, timing & forms
Yes, Arginine and Citrulline can be taken together, and some individuals choose to combine them. Citrulline is converted to Arginine in the body, which can effectively increase Arginine levels. Taking them together may offer a synergistic approach, potentially providing both immediate and sustained benefits.
Citrulline is generally considered more effective at increasing and sustaining blood Arginine levels when taken orally. This is because Arginine itself undergoes significant breakdown in the gut and liver (first-pass metabolism) before reaching systemic circulation. Citrulline bypasses this metabolism and is efficiently converted to Arginine in the kidneys.
For exercise performance, dosages of L-Citrulline typically range from 6 to 8 grams per day. If using Citrulline Malate (often a 2:1 ratio of Citrulline to Malate), a common dose is 8 to 12 grams, providing an equivalent amount of L-Citrulline. For general cardiovascular support, lower doses around 3-4 grams may be suggested.
For exercise performance, typical dosages are 6 to 8 grams of L-Citrulline, or 8 to 12 grams of Citrulline Malate. Citrulline Malate is often a 2:1 ratio (6-8g L-Citrulline). It's generally recommended to take it about 60 minutes before physical activity.
When combining them, it's generally recommended to start with conservative doses for each. Since Citrulline effectively raises Arginine levels, you might consider slightly lower individual Arginine doses than if taking it alone. Monitoring your body's response is key to finding the optimal combined dosage.
health_and_safety Safety & interactions
Yes, L-Arginine and L-Citrulline can generally be taken together. L-Citrulline is a precursor to L-Arginine, and combining them may lead to sustained increases in nitric oxide levels. However, potential additive effects on blood pressure should be considered.
Yes, L-Arginine can interact with medications for blood pressure, erectile dysfunction (e.g., sildenafil), and nitrates, potentially causing blood pressure to drop too low. It may also interact with blood thinners and diabetes medications. Consulting a healthcare professional is crucial, especially if taking other medications.
Common side effects of L-Arginine can include abdominal pain, bloating, diarrhea, and nausea, especially at higher doses. These effects are generally mild and temporary. Individuals may also experience a drop in blood pressure.
L-Citrulline is generally well-tolerated, but some individuals may experience mild gastrointestinal discomfort, such as nausea or diarrhea. These side effects are more likely at higher doses. It can also potentially lower blood pressure.
Yes, L-Arginine can interact with medications for high blood pressure. Because L-Arginine can lower blood pressure, taking it with antihypertensive drugs might cause blood pressure to drop too low. It is advisable to consult a healthcare professional before combining them.
