Histamine Block is now packaged in a moisture-controlled, desiccated bottle for enhanced product stability and potency. This new packaging delivers unparalleled protection for products that are sensitive to outside moisture. A desiccant sleeve surrounds the product creating an impenetrable barrier, contributing to greater product stability over time. Research has shown this container system to be more effective than standard bottles containing desiccants or even blister packs.
Take 1 capsule no more than 15 minutes before the consumption of histamine-rich foods, or take as directed by your healthcare professional.
