Lamberts L-Arginine HCl 1000mg 90 Tablets is a food supplement providing 1000mg of L-arginine, a pure, free-form amino acid that is ready to be absorbed by the body without needing to be broken down by digestive enzymes. The body uses arginine to produce nitric oxide, which relaxes blood vessels and supports healthy blood circulation, and this free-form tablet offers a straightforward way to supplement an amino acid the body may not always make in sufficient amounts.

Key Features

• Pure free-form amino acid: Ready to be absorbed by the body without needing to be broken down by digestive enzymes first.
• Supports nitric oxide production: The body uses arginine to produce nitric oxide, which relaxes blood vessels and supports healthy blood circulation.
• A conditionally essential amino acid: The body may not make enough arginine during periods of rapid growth, trauma or physical stress, when extra intake may be useful.
• Flexible dosing: 1 to 4 tablets can be taken daily, with guidance to take them 30 minutes before a meal or at bedtime.

Is L-arginine safe for everyone, and who should avoid it?

This product is not recommended for children, or for pregnant or lactating women. It is also not recommended for anyone who has had a recent heart attack, as L-arginine has been linked to an increased risk of death in this group. People with a history of herpes infection or asthma should seek advice before taking it, as L-arginine may worsen these conditions.

Can this be taken alongside blood pressure or heart medication?

L-arginine can lower blood pressure. Taking it alongside blood pressure-lowering medication or nitrate medicines, which are often used for chest pain, may cause blood pressure to drop too low, so speak to a doctor or pharmacist before combining them.

What is nitric oxide, and why does the body need arginine to make it?

The body uses the amino acid arginine to produce nitric oxide, a substance that relaxes blood vessels. This vasodilator effect helps maintain healthy blood flow around the body.
