5 Best Probiotics For Adults

In my recent post My 5 Favorite Natural Ear Infection Remedies, I mentioned that I take a probiotic supplement as well as having my kids take a probiotic. Part of surviving with kids is keeping mom and dad healthy.

Edit: See my subsequent review My Top 4 Best Probiotics for Kids for my recommendations for probiotics for kids.

Periodically I check pricing and evaluate if I want to switch things up with any of my supplements. So I have done some comparison research on some of the best probiotics for adults.

First I will describe the criteria that I use to evaluate the probiotics, then I will provide information on 5 top rated probiotics available from amazon.com and finally I will share which probiotic I plan to purchase next for myself.

Selection Criteria: What Is Important

The main 4 pieces of information that I look for when I compare probiotics are:.

1. Number of Billions of CFU (colony forming units): From various research that I have done, I consider 10-20 Billion CFU to be the appropriate range for a daily or maintenance probiotic supplement for an adult. If someone has been taking antibiotics or has severe digestive issues such as IBS, the recommendations I have seen are 25-50 Billion CFU.
2. Number of Strains: I prefer a minimum of 6 different strains of probiotics.
3. If refrigeration is required: I prefer to keep all of my supplements on the same shelf, so I would prefer not to have to refrigerate my daily probiotics.
4. Cost: There are many good quality supplements available for 15-30 cents per serving. I have noted pricing and per serving calculations in my review below based on today’s current pricing. The amazon link box on the right side of each product has the most current one-time purchase price and may vary slightly from what I listed.

So What Should You Choose?

The Sedona Labs product is what I have been taking at the Subscribe & Save 15% price of $15.56 ($0.26 / half serving). Given the much lower price for the Nutrition Now Vegetarian Formula price of $8.99 ($0.15 / Serving), I am going to give this product a spin next month, even though it is recommended to be refrigerated.

You may have some different priorities, so I encourage you use the information I have gathered to make your own decisions. These are all good, highly rated products that serve a variety of people very well.
