Customers can go ahead, double up on any two probiotics that suit their fancy (Mood for mental health, Fit for energy and weight loss, Skin for skin health, or Immunity for an immune boost). In fact, Jetson encourages it. Jetson’s formulations are complimentary – meaning customers will never get too much of one strain and too little of another. If customers decide to do so, Jetson suggests that they split up the doses: one in the morning, one in the evening.
