SBN Nitric Oxide Capsules are formulated to support your training routine with a blend of amino acids and nitric oxide precursors. Designed for those looking for a simple, capsule-based option, this formula combines L-Citrulline, L-Arginine HCL, Agmatine Sulphate and AAKG Alpha-Ketoglutarate - key nutrients commonly used to support blood flow and exercise performance. Each 3-capsule serve delivers a balanced combination of these ingredients in a convenient daily format suitable for regular training and active lifestyles.
This blend features L-Citrulline (1000 mg) and L-Arginine HCL (500 mg)—two well-known precursors involved in nitric oxide pathways. Citrulline is valued for its role in supporting circulation and exercise endurance, while Arginine contributes to the body’s natural nitric oxide production. Agmatine Sulphate (250 mg), a metabolite of Arginine, is commonly included in performance formulas for its complementary role in the same pathway. AAKG Alpha-Ketoglutarate (250 mg) combines Arginine with alpha-ketoglutarate, a compound involved in energy processes, making it a popular inclusion in pump and performance products. Together, these ingredients provide a supportive combination for training sessions where circulation and nutrient delivery matter. SBN Nitric Oxide Capsules offer a straightforward, capsule-based formula designed to fit easily into any pre-training routine. Whether you are lifting, training outdoors, or maintaining an active lifestyle, this blend provides a no-nonsense option for those seeking a reliable nitric oxide support supplement without unnecessary additives.
