Probiotics are the so-called “good” or “friendly” bacteria that live in your gut. There are different types of probiotic strains that have been isolated and defined by scientists for their potential to support our health. Various strains have different effects on the body; some may support digestion, while others are thought to help support immune health, for example.*
Prebiotics are a form of non-digestible fiber found in many foods. These prebiotics pass through your small intestine and then become fermented before they reach the large intestine. It’s here that prebiotics serve as a food source for probiotics, allowing them to grow and thrive within your gut microbiome. Many people refer to prebiotics as a “probiotic booster” for their ability to support a positive environment for the healthy bacteria in your gut.*
Primal Probiotics is expertly formulated to support your gut and overall health. This premium formula blends high-quality prebiotics with 12 diverse probiotic strains for a holistic approach to gut health.*
The best probiotics are the ones that you’ll actually remember to take! Primal Probiotics come in the form of one easy-to-swallow capsule that is taken once daily. Simply take one capsule, preferably on an empty stomach upon waking or right before bed. For best results, use consistently each day.
Each bottle of Primal Probiotics contains 30 servings (30 capsules of probiotics pills), or a one-month supply, if taken daily.
This product contains hydrolyzed bovine and it is manufactured in a facility that also processes tree nuts, peanuts, wheat, and soy. Always review the label closely for the most accurate information and consult with your personal physician when in doubt.
This product is intended for use by healthy adults over 18 years old. We recommend that you consult your physician before use if you are taking any prescription or over-the-counter medications or are being treated for any medical condition.
