Bifidobacterium lactis Strain HN19

17 billion CFU

Bifidobacterium lactis Strain HN19 is a well-researched probiotic known for its ability to support digestive and immune health.* Naturally abundant in the guts of healthy individuals, this strain helps maintain a balanced microbiome by aiding digestion and promoting regularity.* HN19 has been shown to enhance immune function, support gum health, and improve overall gut performance.* It may also help “prime” the digestive system, creating a favorable environment for other beneficial probiotics to thrive.*

Lactobacillus helveticus Strain R52

4.5 billion CFU

Lactobacillus helveticus R52 is a clinically studied probiotic known for supporting both digestive and emotional well-being.* As an established psychobiotic, it influences the gut-brain axis to help improve mood and reduce feelings of stress.* When combined with Bifidobacterium longum R175, R52 has been shown to enhance emotional balance, promote a sense of calm, and support the body’s natural stress response.* This strain also contributes to healthy intestinal function, making it beneficial for both mental and digestive health.*

Bifidobacterium bifidum Strain R71

3 billion CFU

Bifidobacterium bifidum Strain R71 is a beneficial probiotic shown to support both gut and mental well-being.* In clinical studies, R71 helped improve sleep quality, digestive health, and immune function—particularly in individuals experiencing high stress, such as students during exam periods.* By supporting a balanced gut microbiome and the gut-brain connection, R71 may help the body manage stress more effectively, enhance relaxation, and promote better overall resilience during challenging times.*

Bifidobacterium longum Strain BB536

2 billion CFU

Bifidobacterium longum Strain BB536 is a highly studied probiotic known for its effectiveness in promoting digestive and immune health.* It helps maintain a healthy balance of gut bacteria, supports regular bowel movements, and may reduce occasional bloating and discomfort.* BB536 also plays a role in strengthening the gut barrier and enhancing immune system response.* Backed by extensive clinical research, this strain is a reliable choice for supporting long-term gut health and overall wellness.*

Lactobacillus plantarum Strain K31

1.5 billion CFU

Lactobacillus plantarum Strain K31 is a resilient probiotic originally isolated from healthy human infants.* Known for its ability to survive harsh digestive conditions, this strain helps support a balanced gut microbiome and promotes optimal intestinal function.* When used in combination with complementary strains, K31 has been shown to enhance immune system activity and strengthen the body’s natural defenses.* It also supports digestive comfort, nutrient absorption, and overall gastrointestinal health.*

Lactobacillus plantarum Strain K32

1.5 billion CFU

Lactobacillus plantarum Strain K32 is a scientifically studied probiotic known for its role in supporting gut health and immune function.* Though genetically distinct from Strain K31, K32 works synergistically with it to enhance the overall effectiveness of both.* Together, they help maintain a balanced gut microbiome, support healthy digestion, and reinforce the body’s natural immune defenses.* Strain K32 is especially valued for its resilience and ability to contribute to long-term intestinal and immune health.*

Bifidobacterium longum Strain R175

0.5 billion CFU

Bifidobacterium longum Strain R175 is one of the most common and well-established probiotic species in the human gut.* Classified as a psychobiotic, it supports the gut-brain axis and plays a role in mental well-being.* In clinical studies, R175—when paired with Lactobacillus helveticus R52—has been shown to enhance mood, reduce perceived stress, and support emotional resilience.* It also helps maintain digestive balance, making it beneficial for both mental and gut health.*

With consistent use, beneficial strains support healthier immune signaling and gut barrier function. Many report steadier digestion, improved bowel regularity, and fewer stress-related stomach symptoms.*

3 Months+

Continued use helps maintain a thriving gut microbiome that supports long-term brain, mood, and immune health. You may notice better focus, steadier energy, and more consistent well-being from the inside out.*

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.*
