Is 1000mg of L-arginine enough to see benefits?

Yes. While higher doses (3–6g) are often studied for conditions like hypertension or erectile dysfunction, 1000mg daily can still improve circulation, support immune function, and aid in mild exercise recovery. It’s a safe starting point for beginners.

Can I take L-arginine every day?

Yes. Research shows that daily supplementation of 1–9g is generally safe for healthy adults. A dose of 1000mg daily is considered low and well tolerated, making it safe for long-term use when guided by a healthcare professional.

Does L-arginine improve workouts at 1000mg?

At 1000mg, the performance benefits may be subtle. However, consistent intake supports nitric oxide production, which helps blood flow and oxygen delivery. Athletes often use higher doses (3–6g), but 1000mg can still aid endurance and recovery over time.

Who should avoid L-arginine supplements?

Individuals with low blood pressure, kidney disease, liver disease, or those taking medications for heart conditions or erectile dysfunction should consult a doctor before supplementing. L-arginine can interact with certain drugs.
