Overview
•150mg caffeine per serving is moderate but high-caffeine content; not recommended for children, pregnant or breastfeeding women.
•Beta-alanine at 1.6g may cause harmless paresthesia (tingling) in sensitive individuals; splitting doses or chronic use mitigates.
•Vitamins (B-complex, C) at 15-94% NRV are safe and support energy metabolism without exceeding upper limits.
•Suitable for vegetarians and vegans; produced in facility handling milk so trace allergen risk possible.
•Acute use appears safe in healthy adults per studies on similar MIPS; monitor for GI upset from citrulline/arginine.
