Advanced 4x Nitric Oxide Boost
Also known as: L-Citrulline, Citrulline, Nitric Oxide Booster, Nitric Oxide Precursor
Overview
L-Citrulline is a non-essential amino acid that plays a crucial role in the nitric oxide (NO) pathway. It is naturally found in foods like watermelon and is also available as a dietary supplement. As a precursor to L-arginine, L-citrulline helps increase nitric oxide production in the body, leading to vasodilation and improved blood flow. This makes it popular for enhancing exercise performance, supporting cardiovascular health, and managing conditions like erectile dysfunction. L-Citrulline is available in various forms, including capsules, powders, and as an ingredient in pre-workout supplements. Its ability to efficiently convert to L-arginine makes it a more effective NO booster compared to direct L-arginine supplementation. Research suggests that consistent intake of L-Citrulline can lead to noticeable improvements in blood pressure and exercise capacity.
Benefits
L-Citrulline supplementation is primarily associated with improved cardiovascular health and enhanced exercise performance. Studies indicate that L-Citrulline can lower systolic blood pressure, making it beneficial for individuals with hypertension. A systematic review supports this, showing a modest but clinically significant reduction in blood pressure with consistent use. For athletes, L-Citrulline can improve blood flow to muscles, leading to increased endurance and reduced muscle fatigue during exercise. Research suggests that L-Citrulline may also help with erectile dysfunction by improving blood flow to the penile area. These benefits are typically observed within a few weeks of consistent supplementation, with effects varying based on individual factors and dosage.
How it works
L-Citrulline works by being converted into L-arginine in the kidneys. L-arginine is then used by the enzyme nitric oxide synthase (eNOS) to produce nitric oxide (NO). Nitric oxide acts as a vasodilator, relaxing the smooth muscles of blood vessels and increasing blood flow. This improved blood flow can lower blood pressure, enhance oxygen and nutrient delivery to muscles, and support overall cardiovascular health. The L-Citrulline to L-arginine conversion is more efficient than direct L-arginine supplementation because L-Citrulline bypasses the liver's first-pass metabolism, leading to higher levels of L-arginine in the bloodstream.
Side effects
L-Citrulline is generally considered safe for most adults, but some side effects have been reported. The most common side effect is gastrointestinal discomfort, including nausea, bloating, and diarrhea, especially at high doses. Allergic reactions are uncommon but possible. Rare side effects may include severe allergic reactions, though these are very infrequent. L-Citrulline may interact with blood thinners and medications for hypertension, potentially increasing the risk of bleeding or causing excessive drops in blood pressure. Individuals with severe kidney or liver disease should consult a healthcare provider before using L-Citrulline. Pregnant or breastfeeding women should also seek medical advice before supplementation to ensure safety for both mother and child.
Dosage
The recommended dosage of L-Citrulline typically ranges from 2 to 6 grams per day. For exercise performance, a dose of 3-6 grams taken 30 minutes to 1 hour before exercise is commonly recommended. L-Citrulline is often preferred over L-arginine due to its better bioavailability. While a maximum safe dose has not been definitively established, exceeding recommended dosages may increase the risk of side effects. It is advisable to start with a lower dose and gradually increase it to assess tolerance. L-Citrulline can be taken with or without food, but timing it around exercise or meals may optimize its effects.
FAQs

Benefits can typically be observed within a few weeks of consistent supplementation, though individual results may vary.
Is L-Citrulline safe?
L-Citrulline is generally safe for most adults, but it's best to consult a healthcare provider if you have underlying health conditions.
When is the best time to take L-Citrulline?
It is best taken 30-60 minutes before exercise or with meals to optimize absorption and effects.
What results can I expect from taking L-Citrulline?
You can expect improved blood flow, potential lowering of blood pressure, and enhanced exercise performance with consistent use.
Is L-Citrulline a substitute for medical treatment for hypertension?
No, L-Citrulline is not a substitute for medical treatment. Consult a healthcare provider for appropriate management of hypertension.
