Source Naturals Super Amino Night (120 Capsules) is marketed as a comprehensive nighttime supplement, primarily featuring a blend of L-Arginine, L-Lysine, and L-Ornithine. These amino acids are often combined due to their potential synergistic effects, particularly in discussions around pituitary gland function. The formula is augmented with Vitamin B6, which is crucial for amino acid metabolism, and Vitamin C for antioxidant support. Chromium is included for blood sugar regulation, and L-Carnitine is added for its role in fat metabolism. However, a critical assessment reveals that while the doses of L-Arginine (900mg), L-Lysine (900mg), and L-Ornithine (500mg) are notable, the L-Carnitine dosage of 10mg is extremely low and unlikely to provide any significant impact on energy, metabolism, or weight loss goals. The product attempts to address a very broad spectrum of goals, from brain and heart health to immunity and fitness, which is ambitious for its ingredient profile. Online reviews indicate mixed user experiences, with some reporting general well-being improvements, while others note a lack of specific results for targeted goals like weight management or muscle gain. This broad approach with certain underdosed ingredients suggests that while it may offer some general nutritional support, its effectiveness for specific, ambitious claims may be limited.
