Trading since 2000, Markwell Nutrition takes pride in delivering high-quality products to our clients. We initially started with a unique product for the relief of constipation and to aid in gastrointestinal detoxing, which was made from natural ingredients only. In 2014, we re-formulated this fantastic product which was an improvement on the original. Namely ColozonePlus.

Ask a professional



    Will one cleansing completely empty the colon?

    Almost never. Dependant on your age, many people have ten or more pounds of impacted faeces in our colon.
    It took many years to create this toxic material and it takes time to remove the impacted faeces from the colon wall.
    One cleansing will remove some and the second cleansing will remove more. Your individual condition will determine how many sessions you will need to have.

    How much do I take?

    Please see recommendations on label as this is based on how much you weigh.

    Can colon cleansing wash away all bacteria even the good?

    The helpful bacteria can only live in an alkaline environment. Most people, due to years of improper eating, lack of exercise, and poor elimination, have an acidic colon. So it’s helpful to flush away the bacteria in an acidic colon. The great benefit of cleansing is to change the environment from acidic to alkaline.
