Every ingredient is a potent natural immune booster. Great price for the milligram size of each of the ingredients. I appreciate this formula being in capsule form.
Product is easy to * and leaves no after taste or 'burps' teenage son is not too keen on the flavor - very 'peppery' i believe they do & will help ward off any illnesses.
Always fast dependable shipping. Seems to be a quality supplement.
China has notoriously low processing standards. Didn't trust it to consume. It stays in clumps.
