The human body houses trillions of bacteria that work to keep it functioning at an optimal level. Probiotics are wellness supplements that introduce additional good bacteria to your system. These supplements are claimed to provide a multitude of health benefits, from clearing your skin to losing weight to improving brain function.
Most good bacteria live in the intestines. In fact, this is where the bulk of your immune system is housed. At times, the good bacteria in your digestive tract can become depleted, opening the door for bad bacteria to come in and take over. By introducing a probiotic supplement, you can help replenish the good bacteria to keep your body functioning the way it should.
Different strains of probiotics do different things, but none of them will do you any good unless the bacteria cultures are live and unexpired. Potency is another issue you should pay attention to. If you’d like some help sorting out the different probiotics available today, read on for more information.
Most probiotic supplements don’t come with a single strain of bacteria. In fact, there may be seven or more strains in one supplement. This diversity is a good thing because each type of bacteria helps your body in a different way. Here are some of the most common types of bacteria you can expect to find in a probiotic supplement.
B. bifidum is another popular immune-boosting bacteria. Its effects are similar to L. acidophilus: it can help optimize digestion and may even protect against certain intestinal pathogens. Some studies suggest that B. bifidum helps improve the symptoms of irritable bowel syndrome (IBS).
L. rhamnosus is a favorite among travelers because it may help prevent traveler’s diarrhea. It also shows promise in soothing chronic skin conditions like eczema.
Perhaps the most common type of probiotic, L. acidophilus is a hardy bacteria that can help boost your immune system. It also helps with the digestion and absorption of foods. Many people who are lactose intolerant report improved digestion of dairy products when they introduce L. acidophilus into their diets.
B. longum can help inhibit the growth of harmful bacteria in the digestive tract. It may also promote regularity, so if you suffer from constipation, you may wish to consider it. Some studies also suggest that it can help improve brain function by decreasing cortisol levels and improving memory.
It’s important to make sure that the bacteria in the probiotic you choose are alive. Otherwise, the supplement won’t do you any good. Check the label for a phrase like “Live bacteria viable through end of shelf life.” This means that the bacteria are alive and, provided they are stored properly, will remain so through the expiration date listed on the product.
Most probiotics are designed to be taken once per day. Verify the number of pills in one bottle to make sure the expiration date is at least that far out. Otherwise, you’ll be paying for a product that you won’t be able to use.
The best probiotics include multiple strains of good bacteria. Examine the nutrition label to see how many strains – and which types – are included. Are these the strains you need for your particular health concerns?
To determine potency, look at the total colony-forming units (CFUs) in your probiotic. As a general rule, a basic probiotic should have a minimum of 1 billion CFUs per pill – and you can go as high as 10 billion CFUs per pill. There’s no need to go higher than this for everyday use, but if you have a special circumstance, such as being on antibiotics, you may want to look for a probiotic that has as much as 50 billion CFUs per pill.
Most probiotics should be stored in the refrigerator, but there are some that can be safely stored at room temperature. One of these will be a better fit for you if you’re going to be traveling and don’t have access to a fridge or cooler. Be sure to find out the recommended storage method (refrigerated/not refrigerated) before you buy.
Though not crucial, a third-party certification can help you feel confident that the probiotic you’re choosing will live up to the potency listed on the label. Not all probiotic manufacturers go through the certification process because it is expensive, but if you’re particular about which supplements you take, it’s best to look for one that is either USP verified or NSF certified for purity and potency.
Probiotics range in price from approximately $0.20 to $0.85 per pill.
Cost depends somewhat on potency and the number of strains included, but a higher per-pill cost isn’t always indicative of better quality.
Some probiotics cost $0.80 per pill for a single strain of bacteria while others have five or more strains and cost around $0.25 per pill. In short, you should always consider the price of a probiotic in conjunction with its ingredient list.
Don’t wash down your probiotics with chlorinated water. Chlorine kills bacteria and may impact the effectiveness of your probiotic.
Take your probiotic on an empty stomach, preferably when you first wake up in the morning or before a meal.
If you have a weakened immune system or a severe health condition, talk to your doctor before adding a probiotic to your daily diet.
If your probiotic doesn’t require refrigeration, keep it in a cool, dark place where it won’t be exposed to a lot of sunlight or heat.
A. Studies suggest that taking probiotics may help boost your baby’s immune system. But as with anything, it’s best to consult with your doctor before adding a probiotic supplement to your health regimen.
A. Most of the time, they do not – but it is possible. You may experience mild constipation, bloating, or diarrhea when you first begin taking probiotics. This is usually temporary.
A. Antibiotics wipe out much of the bacteria in your body without discriminating between good and bad. While this can help get rid of bacterial illnesses, it can also deplete your immune system, which may take a while to recover. Probiotics, particularly those strains that are known for boosting immunity, can help speed up this process. It’s a good idea to start taking probiotics with your antibiotics and continue taking them for about a month afterward to ensure that your good bacteria returns to a healthy level.
