What Primal Earth Probiotic Does for Your Gut

SIBO-Safe Support†
Soil-based spore-forming organisms provide transient support without colonizing your small intestine where they could feed bacterial overgrowth, making this safe for SIBO-conscious protocols.†

Survives to Your Colon†
Spore-forming technology makes these probiotics one thousand times more resistant to stomach acid than traditional Lactobacillus strains, ensuring they reach your intestines alive and active.†

Rebuilds After Antibiotics†
Resilient spore strains survive harsh post-antibiotic gut conditions and help restore the beneficial bacterial diversity that antibiotics destroyed, supporting complete microbiome recovery.†

Reduces Digestive Discomfort†
Three clinically studied Bacillus strains work synergistically to reduce bloating, support regular bowel movements, and promote comfortable digestion without harsh side effects.†

Key Ingredients

Specialized spore-forming organisms that mimic the beneficial bacteria from our ancestors' paleo diets.

Why I Made This

“My Primal Earth Probiotic contains three different strains of live, inherently viable microorganisms. These soil-based super probiotics have a seed-like structure that protects them from heat, oxygen, and even passage through the stomach and small intestine. It’s super resilient, so you can be too.†”

Frequently Asked Questions

Why don’t I have to refrigerate Primal Earth Probiotic?

Primal Earth Probiotic is made with soil-based probiotic organisms that naturally have a seed or spore-like protective coating. Because of this inherent protection, they are protected from heat, light, and oxygen, and therefore may be stored in a kitchen cupboard, desk drawer, or even traveled with.

How do I know if I should take Primal Earth Probiotics or one of your other probiotics?

We generally recommend Primal Earth Probiotic to those who have tried other lactic acid-based probiotics and have not experienced the level of digestive and microbiome support they have been seeking. Another reason to choose Primal Earth Probiotic over 30 Billion Probiotic or 100 Billion Probiotic is if you travel frequently and want to take your probiotic with you. Primal Earth Probiotic stands up to the rigors of travel very well.

When should I take Primal Earth Probiotic?

Because of its viability and how resilient it is, Primal Earth Probiotics can be taken at any time of the day, with or without food. Many find they feel best when they take it right before bed, and many others report it works best for them when taken with breakfast, lunch, or dinner. We recommend trying it at different times of the day and finding out what works best for you.

Is it safe to give probiotics to children?

We generally recommend our less potent Probiotic 30 Billion for children and teenagers. Because everyone tolerates probiotics differently, we always recommend raising this question with your child’s pediatrician, so that their health history and individual circumstances may be taken into account when forming a decision and before starting supplementation.

How often should I take probiotics?

Take one capsule per day, ideally before a meal to increase the chances of survival of the probiotics through the stomach acid and reaching the gut. However, we recommend you consult with your physician before use to determine what works best for you.

Is it safe to take probiotics when I am on antibiotics?

It is generally safe to take probiotics while on antibiotics, however it's important to speak with your physician first. Antibiotics can disrupt the balance of bacteria in the gut, and probiotics can help replenish the beneficial bacteria. However, certain antibiotics may not be compatible with all probiotics. It's also a good idea to take probiotics a couple of hours before or after taking antibiotics to avoid any irritation and ensure their effectiveness.

    Great Product!!

    This works very well. I have Irritable Bowel Syndrome and the Primal Earth Probiotic has helped cut down on the diarrhea (please excuse if gross). I also have a lot of allergies and sensitivities and I tolerate this very well. The Customer Service at Amy Meyers MD is excellent, and they are totally trustworthy! Thank you!

    Healed my gut!

    This probiotic has been a game-changer! I've struggled with gut issues most of my adult life. For the past 20 years, I've been lactose intolerant and the thought of eating ice cream or pizza would cause so many issues. Since taking primal earth probiotic, those issues have all but gone away. So glad to have finally found a probiotic that works for me!!

    Best Probiotic Ever

    If you can’t take prebiotics or enzymes this probiotic is your answer. I’ve been using these Primal Earth Probiotics for the last couple of months and have been feeling so much better!!!

    They are definitely worth a try if you suffer from IBS etc and cannot tolerate a lot of fiber.

What Are the Signs Leaky Gut Is Healing?
Leaky gut occurs when the intestinal lining becomes compromised, allowing toxins and undigested food particles to enter the bloodstream. This potentially leads to inflammation, digestive issues, and autoimmune conditions. Healing leaky gut involves following a comprehensive protocol to remove irritants, restore essential nutrients, reinoculate with probiotics, and repair the gut lining with targeted supplements like Leaky Gut Revive® and collagen. Learn more about the signs leaky gut is healing.

Are Sugar Alcohols Bad For You?
Sugar alcohols, such as erythritol, xylitol, sorbitol, and maltitol, are low-calorie sweeteners often found in packaged foods. While they can support low-carb diets and dental health, they are heavily processed and may cause digestive issues like bloating, gas, and diarrhea. If you suffer from conditions like Candida overgrowth, leaky gut, or SIBO, sugar alcohols can worsen symptoms by feeding harmful bacteria. Though they are a lower-calorie alternative to sugar, they can still impact blood sugar levels and gut health. To repair gut damage caused by sugar alcohols, consider following a gut-healing protocol like the 4R approach with tools such as Gut ImmunIG™.
