L-Arginine L-Ornithine L-Lysine Complex
Puritan's Pride L-Arginine L-Ornithine L-Lysine Complex is a combination supplement designed to provide amino acids. Each 4-caplet serving delivers 1447mg L-Arginine Hydrochloride, 900mg L-Ornithine Hydrochloride, and 1200mg L-Lysine Hydrochloride, alongside 184mg of Calcium. This product achieved an N+ Score of 46, earning an 'F' grade due to its below-average quality assessment. While label transparency is 100% and it contains 5 ingredients, the Calcium dosage is underdosed compared to typical daily recommendations, and none of the key amino acids are specified as being at clinically studied doses for specific outcomes. This product may appeal to those seeking a blend of these three amino acids.
