    Posted by Anonymous on May 11th, 2018

    I have had other probiotics which have not assisted in reducing discomfort as much as this product. For me this product has been useful in giving relief.

  • Just Right!

    Posted by Connie on Mar 11th, 2018

    This is the first time I am confident the prebiotic and probiotic is right for me.

    I am feeling the energy of full health.

    I feel, systematically, I am in full recovery from the harm of parasites and the medicine to treat the parasites, with all the mucous and inflammation from all that.
