Arginine-Citrulline Sustain – 120 tablets

Jarrow Formulas Arginine-Citrulline Sustain delivers a dual amino acid formula in a convenient tablet form, combining L-Arginine and L-Citrulline in a sustained-release format designed to supply these nutrients to the body over an 8-hour period. Each 2-tablet serving provides 500 mg of L-Arginine (Free Base) and 500 mg of L-Citrulline (Free Base), alongside 10 mg of Vitamin C supplied as calcium ascorbate. The sustained-release design sets this apart from standard amino acid tablets, making it a considered choice for those who prefer steady, extended nutrient delivery rather than a single spike.

This 120-tablet pack is straightforward to incorporate alongside an existing supplement regimen — simply take as directed and let the extended-release matrix do its work.
