Diuretics are sometimes called 'water tablets' because they can cause you to pass more urine than usual. They work on your kidneys by increasing the amount of salt and water that comes out through your urine. Too much salt can cause extra fluid to build up in your blood vessels, raising your blood pressure. Our range of diuretic supplements contains natural diuretics such as dandelion, ginger, parsley, hawthorn and juniper. These tablets and pills may have a diuretic effect that can help with sodium and water retention. Great supplement to speed up weight loss or help shed those last couple of calories before going away on holidays or competing in a bodybuilding competition.
