What Probiotic 30 Billion Does for Your Body

Restores Your Gut Microbiome†
30 Billion viable CFU from 14 clinically studied strains work together to rebuild beneficial bacteria populations throughout the GI tract. Restoring microbial diversity is the foundation of digestive health and every other system in your body that depends on it.†

Supports Optimal Digestion†
When your gut bacteria is balanced, your body digests food more efficiently, absorbs nutrients more effectively, and produces the short-chain fatty acids that fuel gut lining integrity. Customers commonly report less bloating, gas, and digestive discomfort within the first two weeks.†

Strengthens Immune Function†
60–80% of your immune system lives in your gut and your gut bacteria plays a direct role in how it operates. A healthy, diverse microbiome supports both your innate and adaptive immune response, helping your body stay resilient year-round.†

Promotes Healthy Bowel Regularity†
Probiotic bacteria account for up to 70% of the bulk of a healthy bowel movement. When your microbiome is thriving, elimination is regular, comfortable, and predictable.

Key Ingredients

Including L. acidophilus, L. plantarum, and L. rhamnosus that produce lactic acid to create an inhospitable environment for harmful bacteria while supporting digestive comfort and immune function.†

Help maintain a healthy balance of gut bacteria†
A key strain for digestive comfort and immune support. Helps reduce bloating and gas, promotes regular and comfortable bowel movements, and contributes to overall microbial balance in the large intestine and colon.†

Where is the best place to store Probiotic 30 Billion?

Probiotic 30 Billion can be stored in any cool dry place, such as a kitchen cupboard, or a desk drawer. While they do not require refrigeration at all, you may certainly store them in the fridge if you’d prefer to.

What time of the day should I take probiotics? Should I take them with or without food?

Because of the probiotic strains we chose, and the way the capsule delivers the probiotics to your digestive tract, you may take these with or without food, day or night. Try them at different times to see what time of the day works best for you.

Is it safe to give probiotics to children?

We generally recommend our 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.

    Not sure yet...

    These make me very gassy. Never had a probiotic so that before. Can't say I like them yet after a couple weeks. But maybe it'll get better.

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™.
