There are an estimated 100-trillion microorganisms inhabiting the average bowel. The bacteria found in our gut are actually quite useful, keeping harmful pathogens in check, aiding in the digestive process and improving nutrient absorption. While the thought of supplementing bacteria seems off putting, it is an extremely beneficial thing to do.
Benefits of Probiotic Supplements
Supplementing with probiotics has proven to be beneficial for those with Crohn’s disease, irritable bowel syndrome and other digestive system issues. They can contribute to an improved immune function and nutritional uptake, improving the health and function of virtually every bodily system. 
Finding a high quality probiotic supplement is not so easy though. There are many factors that contribute to a quality probiotic. Because they are live organisms, shelf-life and processing techniques play a major role in how many of the live cultures actually reach your bowel.
Here is our list of some of the top probiotic supplements reviewed for your convenience.

Renew Life Ultimate Flora Critical Care
- Total Bifido Probiotic Cultures – 30 Billion
- Total Lacto Probiotic Cultures – 20 Billion
- Total Cultures – 50 Billion
Other Ingredients: Vegetable capsule (vegetable fiber and water), cellulose.
Renew Life – Ultimate Flora Critical Care was found to be among the highest rated probiotic supplements in terms of purity and total bacteria per serving. While the label states it contains 50 billion cultures per serving, it was actually found to contain 83 billion per serving. Under ideal circumstances, this probiotic over-delivers the best possible way.
NOW Foods Probiotic-10
- Total Cultures – 25 Billion
Other Ingredients: Cellulose powder, cellulose, fructooligosaccharides, ascorbyl palmitate, silica.
NOW Foods – Probiotic-10 is another top quality probiotic supplement. Containing almost twice as many cultures as stated on the label, NOW Foods delivers a high quality supplement for a great price.
Our one concern with the NOW Foods Probiotic-10 is the use of unnecessary “other ingredients”.
Healthy Origins Probiotic
- Total Cultures – 30 Billion
Other Ingredients: Microcrystalline cellulose, vegetable capsule (HPMC, water), magnesium stearate, silicon dioxide.
Healthy Origins – Probiotic supplement delivered an astonishing 99 billion cultures, over three times what was stated on the label. The fact that they over-deliver by such a margin ensures you are getting the maximum amount of beneficial cultures per serving.

Nutrition Now – PB8 is not only one of the highest quality probiotic supplements, it is probably the best value in terms of probiotics. Delivering around 33 billion cultures per serving, it far exceeds label claims and doesn’t muck about with unnecessary “other ingredients”. It even offers a vegetarian friendly option, something many probiotics don’t have.
