Where is the best place to store Probiotic100 Billion?

Probiotic 100 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 I 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 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.

Fermented Foods To Avoid With Candida Overgrowth
In my many years of treating patients for Candida overgrowth, I saw a surprising number of people who were surprised to learn that eating fermented foods could actually be making their condition worse.

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™.
