Up to 80% of your immune system is located in your digestive tract, so good digestion is key to helping you feel your best every day! High potency probiotics come in a wide range of formulas and potencies to suit your needs. I love and carry the Advanced Naturals line. With 8 billion to 200 billion live cultures, and up to 40 scientifically studied probiotic strains per capsule, they’re powerfully formulated to help replenish beneficial gut flora and promote digestive and immune health. Work with your immune system this year and give it the boost it needs before it needs it. Stay healthy out there!
