FAQ

Got questions? We’ve got answers. Explore our FAQs or chat with our AI assistant for instant support.

How can I take this supplement?

We recommend adults take 1 capsule (supplying a minimum 30 billion live probiotic units) daily, with food.* Children ages 4 and up also can take this daily dose.* This product is not intended for use during pregnancy.*

What makes ProBrainBiotics MAX different from other probiotic products?

This probiotic supplement is unique because all seven of its strains have shown consistent benefits in clinical trials.* The strains are internationally registered and are well defined for identity and safety.* The capsules are blister packed to ensure freshness.*

Should I rotate my probiotic supplement every 3-4 months for maximum benefit?

No. There’s no clinical evidence this is necessary or even helpful.* With clinically researched strains that are highly likely to improve overall microbiome functioning, the longer they’re consumed the better the results tend to be.*

Does ProBrainBiotics MAX require refrigeration?

The live bacteria in probiotics are sensitive to exposure to air, as occurs when a bottle is opened.* Refrigeration slows the rate of damage, but can’t stop it.* ProBrainBiotics MAX doesn’t require refrigeration – it contains extra bacterial cells to allow for loss over time when stored at room temperature.* We also sealed the capsules individually in blister packs, to protect them from damage due to ongoing exposure to air.*

Are there any side effects to taking ProBrainBiotics MAX?

No. As with other BrainMD products, this is a dietary supplement, not a drug, and isn’t habit-forming.* It’s free from dairy, glutens, sugar, corn, soy, nuts, eggs, yeast, and artificial colorings or flavorings.* It’s compatible with keto or paleo dietary patterns.*
