Menopause symptoms is increasingly a new area that probiotics have been tackling now, which is one of the main areas we concentrated on when reviewing and testing probiotics. Dealing with hormonal changes is an important part to aging gracefully, and Menopause can often lead to low energy, while your metabolism ramps down and weight goes up.

This is why protecting your gut is so important! Housing over 70% of our immunity, our gut directly & impacts our weight, digestion, lungs, heart, and even the brain! And when bad bacteria start outnumbering the good, it can negatively impact one or more of these vital systems. 

Thankfully, millions are seeing outstanding results using probiotics for improved hormones. By supporting gut health, these supplements can also help with immunitysleep, and mood

  • Immense credibility, Dr. formulated
  • Save money from more expensive procedures


  • Has only 6 strains of probiotics, other brands have more

3. Provitalize Probiotics

by Better Body Co

After our rigorous tests we found it wasn’t worth the money. Overall too expensive, and the product itself was average. We thought that other options were better based on the pros and cons.


We found this probiotic was expensive for what you get and sometimes didn’t work despite the high price. We think there is much better value elsewhere, which is why it did not make the top of our list. This product is only a good buy if others are unavailable.

Our Score


  • Popular product online
  • Customers gave an average 4.0 star rating


  • On the expensive side
  • Some customers reported that the probiotic didn’t work for them, despite the high price.
  • Better Body Co, which makes provitalize is not located in the USA, and we prefer American quality control standards.

4. Seed DS-01 Daily Synbiotic

by Seed

Includes prebiotics and probiotics. The ingredient profile is good, we just wish it cost a lot less. Our verdict is that you can get other products that are just as good for less money.


Expensive for what you get. Customers love this brand and it comes recommended by various news outlets, but the fact is that it is a 37 Billion probiotic in expensive packaging. Synbiotic is a name for prebiotics+probiotics, which other brands on our list also have.

Our Score


  • 37 Billion CFUs
  • Re-usable packaging


  • On the expensive side

5. Probiotics 60 Billion CFU

by Physicians Choice

We couldn’t identify a Physician behind Physicians Choice. Some reviews state the packaging oddly changes, and the product inside looks different, which is a concern.


60 Billion CFUs for the price is good, but not worth it based on some of the negative customer experiences. With better quality control, this product could be a better contender in the future.

Our Score


  • 60 Billion CFU
  • Diverse, 10 strain formula


  • Some customers stated they received tampered with product

2 thoughts on “Top 5 Probiotics That Will Transform Your Gut Health

  1. I’ve been taking Provitalize for several months now. It has suddenly stopped working. It would have been nice if the company who makes this product would inform their customers that it could stop working! It is expensive. I won’t be buying that product again!

  2. I bought provitalize because I thought it would help with weight gain and constipation. It only made constipation worse and the bottle came with the sticker wrinkled like a kid stuck it on. That should have been a red flag.
