insights Analysis
This Source Naturals product is the larger, more economical version of its L-Arginine L-Citrulline Complex (ID 195043), offering the same blend of 750mg L-Arginine Hydrochloride and 250mg L-Citrulline per serving. The primary benefit of this version is its significantly improved price per serving, making it a more attractive option for individuals seeking consistent, long-term daily supplementation. While the individual dosages remain moderate for achieving acute peak performance, it remains a reliable choice from a well-regarded brand for general nitric oxide support, with online reviews often highlighting its quality and cost-effectiveness for ongoing wellness.
- Produced by Source Naturals, a reputable brand recognized for its quality and commitment to natural health products.
- Offers an economical price per serving due to the larger bottle size, providing better value for consistent or long-term use.
- Combines both L-Arginine and L-Citrulline, utilizing their synergistic relationship to enhance nitric oxide production.
- The L-Citrulline dosage (250mg) is still relatively low compared to doses often recommended for peak athletic performance or when seeking the primary benefits of Citrulline.
- The product does not utilize L-Citrulline Malate, which is often preferred for its additional performance benefits attributed to malic acid.
- For individuals requiring very high doses of either amino acid, multiple servings would still be necessary, which, while more economical here, could be inconvenient.
- Individuals with low blood pressure or those currently taking medications that affect blood pressure should consult a healthcare professional before beginning supplementation.
- As with any supplement that impacts circulation, monitor for adverse effects, especially if you have pre-existing cardiovascular conditions.

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.
