Short answer: These citations concern research on the individual ingredients, not the finished BloodPril product — a direct, honest distinction worth applying to every cited source.
Why this distinction is repeated across the formula's own materials
This same careful qualifier appears both in the "How It Works" section and the "Scientific References" section — a consistent, honest standard applied throughout.
What this means practically for evaluating the formula
L-Arginine and L-Citrulline are among the more studied amino acids in cardiovascular research — genuine, but distinct from a clinical trial confirming this specific three-ingredient combined formula's effect.
💡 Worth knowing: this same distinction between ingredient research and finished-product evidence is worth applying to any supplement's cited sources.
