L-arginine and L-citrulline are amino acids the body uses to produce nitric oxide, the molecule that relaxes blood vessels and supports healthy circulation. Athletes take them before training to support blood flow, oxygen delivery and endurance, and men often use them as part of a daily vitality routine.* This liquid version absorbs under the tongue rather than relying on digestion.

What's inside

• L-citrulline and L-arginine (1000 mg L-arginine formula)
• Boron and zinc
• Sublingual liquid, mixed berry flavor, zero sugar
• Vegan and non-GMO, with no artificial additives
• 60 ml (2 fl oz) glass dropper bottle

How to use

Hold the labeled serving under the tongue for 30 to 60 seconds, then swallow, ideally 20 to 30 minutes before activity or once daily. Liquid drops are convenient for people who dislike the large tablets these amino acids usually come in. If you take blood pressure or heart medication, check with your doctor first, since nitric oxide boosters can add to their effect.

Why we carry it

Arginine and citrulline usually come as horse pills or sugary pre-workout powders. NIUTRLUXE puts them in a sugar-free sublingual liquid with boron and zinc, packaged in glass rather than plastic. It is a tidy, fast format for a pair of ingredients that otherwise means swallowing several large tablets.
