HelloPharmacist Scorecard of L-Arginine L-Citrulline Complex 1000 mg by Best Naturals
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This tablet contains 2 active ingredients: L-arginine hydrochloride and L-citrulline, totaling 1,000 mg per dose. L-arginine is an amino acid that your body uses to produce nitric oxide, which relaxes blood vessels.
L-citrulline is another amino acid that your body converts into L-arginine, giving it similar effects. The rest is inactive ingredients — binders and fillers like microcrystalline cellulose, dicalcium phosphate, and magnesium stearate that hold the tablet together.
Does it work?
Moderate evidence
L-citrulline is possibly effective for athletic performance — some evidence suggests it may help with exercise capacity. For sarcopenia (age-related muscle loss), it's rated possibly ineffective.
The evidence for cardiovascular disease, heart failure, Reye syndrome, and diabetes is insufficient right now; we don't have enough reliable data to say whether it works for those uses. L-arginine's effectiveness ratings are not on file in our data.
How safe is it?
Well-documented data
Both ingredients are generally well tolerated in the short term when taken by mouth. The most common side effects are gastrointestinal — abdominal pain, bloating, nausea, diarrhea, and heartburn — plus headache, insomnia, and flushing.
Because L-arginine can lower blood pressure and L-citrulline's long-term safety isn't fully studied, use only under medical supervision; safety for self-treatment isn't well established. For pregnancy: L-arginine is rated possibly safe, but L-citrulline should be avoided — there isn't enough safety data.
For breastfeeding: L-citrulline safety is unknown, so it's best to avoid it. There's no lactation data on file for L-arginine.
Talk to your doctor or pharmacist before taking either ingredient if you're pregnant or breastfeeding.
Meds to double-check
Moderate interaction found
Before taking this product, check your blood pressure medications (ACE inhibitors, ARBs, and other antihypertensive drugs), blood thinners, diabetes medications, potassium-sparing diuretics, sildenafil (Viagra), and phosphodiesterase-5 inhibitors — all carry Moderate interaction risks. Your doctor or pharmacist can help you decide whether it's safe to combine them with this supplement.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is for people interested in amino acid supplementation for blood vessel health or athletic performance, but it carries real interaction risks — especially with blood pressure medications, blood thinners, and diabetes drugs. If you take any prescription medications, check them against the interaction tool on this page before starting.
Talk with your own doctor or pharmacist about whether it's right for your health and medications.

Formula
L-Arginine and L-Citrulline are two amino acids bundled into a single powerful supplement. L-Arginine is an important factor in muscle metabolism and is a precursor for nitric oxide, which promotes increased circulation by relaxing blood vessels. L-Citrulline helps the body rid itself of ammonia, a by-product of exercise. This clearing enables the body to recover after a workout. Certain research publications indicate that it may help support the following: Supports protein metabolism. Supports maintain muscle tissue. Supports heart function & circulation.

L-Arginine Hydrochloride
Ace Inhibitors (Aceis)
Theoretically, concomitant use of L-arginine and ACE inhibitors may increase the risk for hypotension and hyperkalemia.
Combining L-arginine with some antihypertensive drugs, especially ACE inhibitors, seems to have additive vasodilating and blood pressure-lowering effects. Furthermore, ACE inhibitors can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ACE inhibitors with L-arginine may increases the risk of hyperkalemia.
Angiotensin Receptor Blockers (Arbs)
Theoretically, concomitant use of L-arginine and ARBs may increase the risk of hypotension and hyperkalemia.
L-arginine increases nitric oxide, which causes vasodilation. Combining L-arginine with ARBs seems to increase L-arginine-induced vasodilation. Furthermore, ARBs can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ARBs with L-arginine may increases the risk of hyperkalemia.
Anticoagulant/Antiplatelet Drugs
Theoretically, concomitant use of L-arginine with anticoagulant and antiplatelet drugs might have additive effects and increase the risk of bleeding.
Preliminary research suggests that L-arginine infusions reduce platelet aggregation in humans. The clinical significance of this effect is unclear.
Antidiabetes Drugs
Theoretically, concomitant use of L-arginine might have additive effects with antidiabetes drugs.
Preliminary clinical research shows that L-arginine decreases blood glucose levels in patients with type 2 diabetes.
Antihypertensive Drugs
Theoretically, concomitant use of L-arginine and antihypertensive drugs may increase the risk of hypotension.
L-arginine increases nitric oxide, which causes vasodilation. Clinical evidence shows that L-arginine can reduce blood pressure in some individuals with hypertension. Furthermore, combining L-arginine with some antihypertensive drugs seems to have additive vasodilating and blood pressure-lowering effects.
Isoproterenol (Isuprel)
Theoretically, concurrent use of isoproterenol and L-arginine might result in additive effects and hypotension.
Preliminary clinical evidence suggests that L-arginine enhances isoproterenol-induced vasodilation in patients with essential hypertension or a family history of essential hypertension.
Potassium-Sparing Diuretics
Theoretically concomitant use of potassium-sparing diuretics with L-arginine may increases the risk of hyperkalemia.
Potassium-sparing diuretics can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients.
Sildenafil (Viagra)
Theoretically, concurrent use of sildenafil and L-arginine might increase the risk for hypotension.
In vivo, concurrent use of L-arginine and sildenafil has resulted in increased vasodilation. Theoretically, concurrent use might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.
Testosterone
Theoretically, concomitant use of L-arginine and testosterone might have additive effects.
In clinical research, L-arginine increases the level of testosterone in male patients with erectile dysfunction. The clinical significance of this finding is unclear.
L-Citrulline
Antihypertensive Drugs
Theoretically, concomitant use of L-citrulline with antihypertensive drugs might have additive effects and increase the chance of hypotension.
L-citrulline is converted to L-arginine, which can increase nitric oxide and cause vasodilation. However, a meta-analysis of 5 small clinical studies suggests that taking L-citrulline 3-6 grams daily for 1-8 weeks does not lower blood pressure when compared with control.
Phosphodiesterase-5 Inhibitors
Theoretically, concurrent use of phosphodiesterase-5 (PDE-5) inhibitors and L-citrulline might result in additive vasodilation.
L-citrulline is converted to L-arginine, which can increase nitric oxide and cause vasodilation. Theoretically, taking L-arginine with PDE-5 inhibitors might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.
