Frequently Asked Questions

At Probulin, We Believe In Education Before Supplementation.

It’s important to know what we’re putting in our bodies, especially when the end goal is comprehensive digestive health.

If you’re new to Probulin probiotics or if you’re thinking of making the switch to Probulin, questions around the benefits of daily probiotics, efficacy, and shipping are all to be expected. In an effort to help you on your health journey, here’s a list of some commonly asked questions.

Product FAQ

What is a prebiotic?

Prebiotics are fractions of soluble fiber that are food for probiotics. Not all fibers are prebiotics, the determination has to do with the chemical bonds that make up the fiber. At probulin we use Inulin made from chicory root, among the most studied prebiotic sources. There is debate among researchers as to whether other plant molecules such as polyphenols could also function as a prebiotics.

What is a probiotic?

The World Health Organization refers to Probiotics as microorganisms (select yeast and bacteria) that provide a benefit to the host when consumed in adequate amounts. Probiotics have been linked in countless clinical trials to supporting immune health, as well as healthy bowel function, and proper digestion of the food we eat.

What are postbiotics?

Compounds created by probiotics that condition their environment and encourage growth and stability. These postbiotic compounds may include such things as:
● Amino Acids
● Bacteriocins (natural defensive compounds)
● Short Chain Fatty acids (nourishing for humans and promotes growth of probiotics)
● Other Organic Acids and metabolites

How do you choose the best probiotic?

At Probulin, we believe you should look for:
● Correct CFU’s (10 to 20 Billion CFU is all that is truly needed)
● Robust probiotic strains
● Prebiotics, like Inulin, to nourish probiotics .
● Scientifically studied delivery system demonstrated to ensure a greater number of surviving beneficial probiotic bacteria — We believe the ultimate delivery system is MakTrek-3D which goes beyond other probiotic delivery systems.

What is the best time to take a probiotic?

Bedtime is the BEST time for probiotics. However, all Probulin® products may be taken with or without food and can be taken during the day or in the evening.

Does a higher CFU count of bacteria work better?

It’s not about how many billions you take, but rather about how many will survive the journey. Research suggests that simply ingesting more CFUs will not necessarily deliver better results. For this reason, Probulin®uses the scientifically validated MAKTrek® 3-D Probiotic Delivery System to provide better survival of beneficial bacteria.

Are probiotics safe for kids?

Yes! Probiotics specifically formulated for kids are generally safe for them. It’s always a good idea to work with your child’s pediatrician when trying new products with your little ones. Some doctors recommend waiting until they are at least one year old before using a probiotic.

What is the "Seaweed Submarine"?

This is part of the MAKTrek 3-D delivery system: A secondary barrier created by brown seaweed polysaccharides to protect the beneficial probiotic and provide a micro-environment for proper acid protection and hydration through the digestive process all in order to deliver better probiotic survival.

Where does the seaweed come from?

It's sustainably harvested off the coast of Chile and Peru.

Does your product contain iodine or kelp?

No, it does not.

Are Probulin products considered vegan?

They are essentially Vegan, as they do not contain any animal derived product (unless you consider probiotic cells to be animals!) but we do not have the Vegan Certificate.

Do you have any animal derived ingredients in your product?

No, we do not.

Can I take a double dose of probiotics if I’m not having good results?

Generally, this is not necessary. Our products are intended to be used as directed or as suggested by your healthcare practitioner. However, it should be noted that under 50 Billion cells per day is a safe supplemental range in the probiotic industry.

When taking a probiotic and an antibiotic what is the recommended time you should take them apart?

There is significant controversy about this question, generally it is recommended to separate the time of ingestion by at least 2 hours. If you are taking a medication it is wise to consult with your healthcare professional before taking our product.

Are the probiotic strains in the probiotics soil based or freeze dried?

Freeze Dried. We do not use “Soil-Based” bacteria (spores). And if you want to know more about why please ask us at:

After taking probiotics for a long period of time does your body stop producing as many good bacteria in your gut because you have supplemented it for so long?

No. Our bodies do not produce bacteria and there is no evidence of a negative feedback loop with probiotics in our body. Modern diets tend to contain less cultured/fermented food in our daily diets compared to our ancestors.

Does Probulin provide 3rd party testing to show verification of the number of living bacteria per serving?

Probulin is proud to be among the first to use laser-based technology to count bacterial cells in a more consistent and accurate way compared to traditional CFU. This technology is called Flow Cytometry. Flow cytometry allows measurement of how many are alive, versus dead or injured cells. (CFU technology has never had this ability.)

What is CFU and why is it important in a probiotic?

Colony Forming Unit – is the most common way of estimating how many probiotic cells are contained in the product. Note that while CFU counts are important there are known limitations with this method in terms of accuracy and speed.

Should I take a probiotic supplement every day (especially if I already eat a healthy diet)?

Everyday factors such as diet, alcohol consumption, exposure to modern chemicals, and how often you consume traditional cultured food in modern diets can impact the balance of healthy bacteria in your digestive tract. Consistent use of a probiotic will help to support the digestive microbiome more efficiently.

What does "potency" mean in a probiotic?

There are several factors to consider when estimating the potency of a probiotic it’s not as simple as measuring total cell count! Here are some of the factors to look for: The number of cells provided, the capabilities of the selected strains, the quality of the manufacturing process, and finally the specific interaction of the bacteria on the intestine. It is our belief that simply flooding the intestine with probiotics is not the most effective strategy.

What can I expect when I begin taking a probiotic?

When first taking a probiotic, many experience a positive change in their digestion with reductions of occasional gas and bloating. For others, there is a short period of adjustment which can include some temporary discomfort, such as more gas and bloating, for a short time as probiotics work.

Can I open the capsule and empty the powder into food or beverage?

Yes. However, the MAKTrek 3-D probiotic delivery system contains a seaweed polysaccharide that is meant to be taken with the probiotics and will not be as effective without the delivery system.

Can I take a probiotic if I’m pregnant?

Probiotics have generally been deemed to be safe. Nonetheless we believe that pregnant or lactating women should always consult their healthcare professional before taking any supplement.

I thought I needed to refrigerate my probiotics? Aren’t refrigerated probiotics best?

Probulin probiotics are shelf-stable and do not require refrigeration. This is due to the effective moisture barriers and selection of sturdy strains. Though refrigeration is not required, it may extend shelf life. Normal ambient temperatures are not of great concern for Probulin Probiotics.

Does Probulin guarantee the cell count of our Probiotic products?

We have completed real-time stability studies on our products and we have great confidence that when stored as directed, every Probulin probiotic should meet its potency claim until the “Best By” date listed on the package.

Why would I take a probiotic supplement?

Probulin probiotics—and beneficial bacteria in general—can play an integral role in how to cleanse your digestive system. Probiotics support optimal digestion and regularity, immune function, and even offer relief from the discomfort of occasional gas & bloating.

In order to get the most out of your probiotic, it’s important to also know which foods have prebiotics, the fibers that serve as fuel to your friendly flora. Eating a diet rich in these fibers can enhance the health benefits of probiotics.

Which Probulin probiotic should I take?

At Probulin, questions like this come in a fair amount. While our Total Care is a great formula for overall support, there are more targeted formulas for immune support, women’s health, colon care, and even children’s health. There’s truly a Probulin probiotic that’s perfect for everyone. We encourage you to browse our line of Probulin Probiotics to determine which formula is best for you.

Make sure you understand–what does CFU mean in probiotics? – before deciding on an appropriate amount to take.

Are probiotics safe for everyone?

In order to ensure safety, always check the best by on the product you’re taking. If you’ve wondered, do probiotics expire? The answer is, eventually yes! Checking expiration and allergen info is always a must.

If someone questions Probulin products’ safety or efficacy, they need look no further than our third-party verification and our certificates of analysis.

What if I have Probulin questions related to my health?

We understand that everyone’s body is unique and therefore requires unique-to-them care. If you have questions about your health—digestive or otherwise—you should always consult your trusted healthcare provider before adding supplements to your regimen.

Can probiotic supplements protect my immune health?

Believe it or not, 70% of your immune system lives in your gut. (Crazy, we know.) Probiotics assist your immune system in several key ways, including supporting your digestive system. For some people, their microbiomes can get out of whack, which can also affect their immune health. By helping to rebalance the microbiome, probiotics can support digestive health and immune health at the same time.

How do digestive enzymes work?

Digestive enzymes are critical to breaking down your foods so that the nutrients you eat can be more easily absorbed into the bloodstream. Some people struggle to break down foods that contain enzyme inhibitors, like beans, potatoes, wheat germ, eggs, and more. Digestive enzyme products can help this breakdown process, so your body absorbs more of the nutrients you need.

How can probiotics help my skin?

Can probiotic extracts really improve your skin? The answer is yes, as long as you apply the right kind. Microbes already live on your skin and play an important role in how your skin looks and stands up to environmental stresses. Our topical probiotic products contain probiotic extracts that may be able to support the skin’s natural renewal process, resulting in improved skin appearance. Here’s a deeper look at how probiotic skincare products work and how probiotics can help your skin.
