It includes Saccharomyces boulardii which is a probiotic heavily supported by research for its anti-inflammatory and immunomodulatory health benefits. In addition, it contains a top-quality prebiotic, Fructooligosaccharides (FOS), to boost the production of healthy bacteria in the gut as well as balance pH levels. It does not contain any additives or preservatives and is totally 100% safe to use with no long-term side effects. It is also vegan friendly, which is rare with probiotic supplements.

ProbioticXL is manufactured by Great Healthworks and makes good use of 10 strains of probiotics. An effective probiotic formula should contain multiple strains for better results. So, while we were pleased to see the multiple strains included in the formula, we were disappointed that the strength is only 11 billion CFU.  

The manufacturer’s website is packed with information, which is useful when you are looking to buy a health supplement. However, not all of this information is so clear. It is hard to really find out the finer details of the product. Even the information about a guarantee is written in small print at the bottom of the site and could easily be missed.

Vitalite Now Probiotic & Prebiotic

We were happy to see that this product comes with a money-back guarantee and is GMP certified, when so many products today are not. We also like that this probiotic supplement contains a prebiotic. The prebiotic in this supplement is a blend containing 4 strains. It is a patented prebiotic formulation, but the manufacturer does not provide much information about it. 

This product fell a bit short compared to other products we have reviewed because it only contains 4 probiotic strains, so it will offer fewer benefits. Its potency is also very low at only 4.4 billion CFU. Another downside to this product was that it doesn’t offer any discounts for multiple purchases which is a shame. While this doesn’t necessarily mean you shouldn’t buy the product, if you are looking for a cost-effective long-term solution, this may not be the one for you.  

Since the company sells a variety of supplements and has some excellent research behind their products we definitely recommend you read out the full review for the big picture.
