If you do not like taking your oral multivitamins or have been feeling sluggish lately, then our Nutrient Boost bag is for you. It contains vitamin C, a mix of B vitamins including vitamin B12 for energy, and magnesium. The Nutrient Boost bag is especially great for patients with GI concerns such as Celiac disease, Crohn’s, Irritable Bowel Syndrome, diarrhea, and malnutrition. It is administered intravenously and therefore bypasses your digestion tract for maximum benefits.
