Stoplight Info

How Does Your Gut Feel?

After consuming prebiotic fiber & antioxidants, you feel:

  1. What is the purpose of the Stoplight System?

    The Stoplight System helps you identify how each Dr. Mercola® or Pure Power supplement may impact your gut health, so you can make choices that support your microbiome journey, whether you’re just starting or have a strong gut foundation.

  2. Do I need to choose only Green products if I’m just starting?

    While Green products are generally best for beginners, it’s more about how you feel. If you’re comfortable, you may explore Yellow-labeled products and gradually build up from there to Red.

  3. What if a product isn’t labeled with a Stoplight color?

    All branded Dr. Mercola® supplements are included in this system, including subbrand Biothin®, as well as our Pure Power sports nutrition supplements. All of our Mercola Market products are safe to use but may not align specifically with the Stoplight System criteria.

  4. Are probiotics included in this system?

    Yes, all Dr. Mercola® probiotics are included in the Stoplight System. While some are currently labeled Yellow, we are working to reformulate them for the Green category, as probiotics play an important role in the gut health journey, especially for beginners looking to build a strong foundation. As always, we recommend consulting with your healthcare provider to determine the best probiotic for your needs.

  5. Can I take products from different categories?

    Yes, you may take products from different categories based on your needs and how you feel. Green and Yellow products may be taken together, as long as the Yellow ones are well-tolerated, while you continue on your journey toward a balanced gut.

  6. What should I do if I feel discomfort from a Red product?

    If you experience discomfort, you may want to switch to Yellow or Green products, which could be easier on your digestion. Once you feel more comfortable and your gut health has improved, you may try reintroducing the Red product.

  7. Why would I use a Red product if it might cause discomfort?

    Red products are for those with strong, resilient digestion and are meant to provide powerful support. If you have a solid gut health foundation, Red products can be very beneficial.

  8. How often should I reassess my gut health to know when to switch categories?

    It’s a good idea to reassess every few months or whenever you notice significant changes in how you feel. Progress can be gradual, so listen to your body.

  9. Are Stoplight labels a permanent fixture on all products?

    Yes, the Stoplight labels will remain on products to continuously guide customers in making choices that align with their gut health.
