L-Arginine HCL Powder

L-Arginine HCL vs Regular Free Form Arginine

The HCL, or salt, format of arginine tastes better than regular free form arginine, which is also just called L-arginine.

L-arginine HCL also mixes better with drinks and may have better bioavailability.

Arginine Benefits

This amino acid promotes blood flow during workouts, which contributes to muscle pump.

Due to arginine’s vasodilation benefits, it stacks well with supplements which constrict blood vessels, such as caffeine.

Dosage and Instructions

Arginine doses vary from 1 gram to 3 grams. Take up to 3 times daily.

Goes Well With

L-arginine stacks well with the L-theanine and caffeine combo as it can mitigate the vasoconstriction of caffeine.
