Probiotics are live microorganisms that can provide some health benefits when taken in sufficient amounts. They are often referred to as “good bacteria” because of their role in promoting a healthy gut. In recent years, these good bacteria have gained significant importance due to their emerging role in supporting overall health.


To truly understand why you would take a probiotic supplement, you have to first understand the bacteria in our body. Large numbers of microorganisms live on and inside our bodies. Some of the bacteria can be helpful (the good bacteria) and some not helpful. It's preferable to have more helpful than unhelpful bacteria.

That’s where probiotics may be beneficial. Many of the microorganisms in probiotic products are the same as or similar to the beneficial microorganisms that are found in our bodies. As the research on the importance of gut health grows, so does the popularity of probiotics. Dietary supplementation with friendly microbe strains in the form of a probiotic supplement may help replenish healthy bacteria in the gut. Probiotics may also support immune health, aid digestion and nutrient absorption and produce certain vitamins.

Intestinal & Digestive Health

Inmune Support

Allergy and Skin Conditions Support

Urinary and Feminine Health

Cardiovascular Health

Faster Metabolism


Consuming probiotics is important for all individuals regardless of age, lifestyle, or gender. It can be consumed by children, teenagers, adults, and even pregnant women. The main reasons are:

Incomplete Diet

Not consuming the adequate amount of fermented foods.

Taking Antibiotics

These can kill beneficial bacteria in the gut.


Beneficial bacteria can be reduced with age.

Digestive Problems

Probiotics help with Intestinal & Digetive Health.


How to choose the right probiotic supplement?

Probiotic supplements are recommended for more than just daily digestive support. Emerging research shows that certain strains may have benefits beyond digestive health. Probiotic supplements are currently being investigated in the context of oral and vaginal health, immune health, mood, cholesterol levels, weight management, sports performance, beauty and more.

The right probiotic for you will depend on your goal.Probiotics are identified by first the genus name (i.e. Lactobacillus), followed by a species name (i.e. acidophilus), and lastly a strain name (i.e. CUL 60). There are hundreds of probiotics strains in the human body. A strain is an identification of bacterial specificity that distinguishes one strain from another. Strain names are important because the data supporting one strain–or blend of strains–does not necessarily support another.

If your purpose in shopping for a probiotic supplement is to help a specific need, you’ll want to make sure that strain was studied to support those specific results. Whereas other probiotic products may contain a blend of strains that have been studied for general digestive health and may be recommended for daily gut support.

What are the best probiotic supplements?

A variety of factors affect the ability of a particular probiotic to make its way to the colon and potentially have a beneficial effect. A probiotic supplement must first survive production and storage. Heat pasteurization and temperature extremes during storage can destroy these microorganisms. Probiotics must also be capable of surviving the low pH of the stomach and reach the colon where some may adhere to the intestinal cells.

A specialized freeze-drying process is necessary to ensure that the healthy bacteria found in your probiotic bottle survive the travel to and through your digestive tract.You won’t be able to identify a high-quality probiotic supplement from looking at the strain alone—you’ll want to shop for probiotic supplements that have been clinically studied to provide daily support and guarantee the potency.

Life’s about balance. Feel confident you’ve got the essentials covered with a GNC probiotic. GNC supplements are scientifically formulated, quality-checked and real-life approved.

How many probiotics should I take?

The amount of probiotics best for you will depend on your goals.

Here is an outline to follow for dosage:

25 Billion CFU (colony forming units): Daily digestive support

50 Billion CFU: Mild-Moderate need

75 - 150 Billion CFU: Heightened need

Aren't all probiotics the same?

Not all probiotics are created equal. They're living organisms that have the potential to die off when not properly produced, stored, or packaged. GNC's proprietary blend of probiotics are clinically studied. When you choose a GNC probiotic you're choosing a scientifically validated approach to supporting GI health; no guessing here. Also note that GNC probiotics contain FOS (fructooligosaccharides), a food source for living bacteria.

What are probiotic strains and why are they important?

The strain of a probiotic can be likened to a job title. Certain strains have been shown to work more effectively than others just as some strains are hardier than others, etc. The strain of probiotic is identified as L. acidophilus, B. bifidum, or B. lactis just to name a few.

Can't I just take yoghurt?

Yes, you can eat yogurt to receive good bacteria but at a significantly lower potency. There's no telling how many probiotic organisms have died off while still in the container because there is typically no testing for it. Also, to receive 25 billion CFUs in yogurt form, you'd have to eat more than ten 4oz. servings of yogurt. And what do you do if you're dairy intolerant? The choice is easy here.
