L-Citrulline & L-Arginine Stack
The L-Citrulline & L-Arginine Stack pairs L-Citrulline DL-Malate with two forms of L-Arginine in one simple daily capsule made for active bodies. These amino acids are what your body uses to produce nitric oxide, which helps support healthy blood flow and the delivery of oxygen and nutrients to working muscles. It's built to fit into your training routine — supporting exercise stamina and muscle recovery after a workout — without a long list of extras. We're not promising a pre-workout miracle; just clean, measured support you can take consistently.

- Is it safe to take with other supplements or medications?
- It's a simple amino acid blend, but if you're pregnant, nursing, taking medication, or managing a medical condition, check with your physician before starting this or any supplement.

- A short, focused formula: three active amino acids in a vegetable-cellulose capsule, in carefully measured amounts, with nothing flashy piled on top.
