With so many probiotic brands to choose from, out of all of the research and reviews we looked at, 1MD was not only one of the most popular but it also contains one of the best formulas. Considering it is 100% vegan, and endorsed by an actual MD, it's a highly popular choice amongst consumers.

This probiotic has a huge amount of positive reviews, and the overwhelming majority said that it works very well for them. The small pill makes it really easy as well.

The product has really good reviews overall, but it definitely falls short in terms of the CFU count. The other products have very high CFU counts, and the reason why CFUs matter especially for probiotics is because they are an indicator of how many living beneficial bacterial cells you ingest with your probiotic. In order for the probiotic to be effective, the good bacteria you swallow should be alive.

For someone that maybe is more sensitive than others, this may be a great product due to the low CFU count and them using a single strain. It's definitely cheaper than other options out there, but also may be less effective, so that is something to keep in mind with this product.

With over 100 billion colony forming units (CFUs), this is one of the strongest probiotics on the market. With that, if you are sensitive, you should be cautious. Wholesome Wellness’s probiotic does not contain any binders, soy, gluten, milk, or any additives or preservatives. Overall, the reviews for this product are highly positive and consumers like it for the large diversity in bacterial strains, and the fact that it has such a high CFU count.
