Why this is described as "the genuinely clever part"
This direct, enthusiastic framing signals a formulation detail the site considers genuinely well-designed, not just a standard ingredient inclusion.
Why this detail is described as one most reviews skip
The citrulline detail most reviews skip is listed directly among what makes BloodPril different — worth appreciating this level of mechanistic detail most competing pages don't provide.
💡 Worth knowing: L-Citrulline often raises blood arginine levels more effectively than arginine supplementation alone — the direct payoff of solving this specific absorption problem.
