Short answer: Niacin supports cellular energy production, while Beta-Alanine is more commonly studied for physical performance — two ingredients rounding out the formula beyond the core nitric-oxide amino acids.
Niacin: cellular energy, not circulation
Niacin (Vitamin B3) helps the body convert food into energy and supports normal nervous system function — a distinct mechanism from the nitric-oxide pathway targeted by the amino acids.
Beta-Alanine: an honest evidence note
Beta-Alanine is commonly used in sports nutrition to support physical performance, though research on its direct brain-health benefits is still limited — an honestly framed, moderate-evidence inclusion.
Why these round out rather than duplicate the formula
Niacin's cellular-energy role and Beta-Alanine's general performance-support profile add breadth to a formula otherwise concentrated on the nitric-oxide pathway.
