The Best Probiotic for Women Over 50

It seems that every year I have a new set of health problems. Not only that, but with each problem comes 10 people trying to sell me something. 

When I first learned about probiotics I was immediately thrown off by the unbelievable numbers and health claims on the bottles. I just wanted to find the best probiotic for women over 50, encountering the usual associated health problems.

Let’s explore.

What Are CFUs?

Colony-forming units (CFUs)  are the number of cells able to create a colony. CFUs are used in research to estimate the number of live bacteria present in a sample.

CFUs are typically calculated by counting the number of formed colonies after a sample is plated in agar. 

CFUs are the live bacteria in probiotics. They are important because they are what create the health benefits associated with probiotics, such as improved gut health, boosted immunity, and more. When choosing a probiotic, it is important to look for one with a high CFU count.

Many of the counts aren’t accurate and while the health claims are, these probiotics can be found in food. So do you really need them?

The truth is, probably not. With that said, the CFU count in food is even more unreliable due to differences in production and storage. As this article will explore later, the CFU count for sauerkraut can range from 1,000 to 100 million CFUs per serving.

There is a growing body of evidence that suggest that probiotics found in food have a significant impact on health. Bacteria is thought to play a role in everything from immunity to gut health.

What Is the Difference Between CFUs and Cultures?

CFUs and probiotic cultures both refer to the number of live microorganisms in a given sample. CFUs should refer to the percentage of cultures that have been tested to be effective in producing colonies.


It is not uncommon to encounter misleading wordplay or false counts when browsing probiotic supplements.

Probiotics vs Prebiotics

There is a lot of confusion about probiotics and prebiotics. Both are important for gut health but they have different roles.

Probiotics are live microorganisms that can help improve gut health. Prebiotics are non-digestible fibers that are food for probiotics. Both probiotics and prebiotics have been shown to boost immune system function, digestion, and reduce inflammation.

What Do Probiotics Do for Women

There is growing evidence that probiotics can help with the vaginal, urinary tract, and yeast infections.

This can help with Bacterial Vaginosis. There is also evidence that probiotics help with digestion, gut health, and weight loss.

Bacteria is a natural part of human health so it isn’t surprising that maintaining a bacterial balance has health benefits.

Benefits of Probiotics for Older Adults

As we age, our gut health can decline. This can lead to a decrease in the number of good bacteria in our gut and an increase in the number of bad bacteria.

Probiotics are live microorganisms that can help to improve gut health by restoring the balance of good and bad bacteria.

There are many probiotic strains with their own set of benefits. Some are effective for specific health conditions. 

Others, such as Longum and L. acidophilus, are more general and can be beneficial for overall gut health. 

Some of the most common probiotics include Lactobacillus and Bifidobacterium.

Studies have found that probiotics help relieve symptoms of digestive disorders like irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), as well as other conditions like allergies, asthma, and eczema.

How To Choose a Probiotic

 Intended Use

  • Hot flashes: Bifidobacterium and Lactobacillus
  • Weight Loss: Bifidobacterium and Lactobacillus
  • Digestive issues: Saccharomyces boulardii
  • Joint painLactobacillus vaginalis, Acidophilus, L. reuteri,  Lactobacillus hominis
  • Boosted Immune system: Lactobacillus rhamnosus, Bifidobacterium, and Lactobacillus
  • Bacterial Vaginosis: Lactobacillus rhamnosus

Bifidobacterium and Lactobacillus are the most common and versatile probiotics. They are species that contain their own strains with specialized usage. 

CFU Count

Choose a reputable brand with reasonable claims. CFU counts can be false or misleading. 

With that said, probiotic CFU count is important for a few reasons. First, it helps determine the strength of the probiotic.

A higher CFU count means that there are more live, active cultures in the probiotic. This is important because live cultures are what provide the health benefits associated with probiotics.

Second, the CFU count can help you gauge how well a probiotic will work for you. If you tried a probiotic with a low CFU count and didn’t see results, then you may want to try a higher CFU count. 

Lastly, the CFU count can help you determine how long a probiotic will last. Probiotics with a higher CFU count will generally have a longer shelf life. Verifying that CFU count, however, is another issue. 

Third-party Testing

There are studies that have tested the CFU count of probiotics. This study found only 27% of probiotics actually met or exceeded their claimed bacterial content. 


For this reason, the best indicators are the rating and amount of ratings found in the table above. We compiled all of the most well-reviewed probiotics for a reliable list.

While the counts for many of the supplements are likely off, their reviews indicate that these probiotics’ CFU counts is enough for their intended use. 

Storage Needs

Probiotics are living bacteria that survive in well-insulated bottles sheltered from sunlight. Look for the tag “shelf-stable” or a variation to see a company’s consideration of this issue. If the bacteria is dead, it won’t do anything for your health.

 How Much Probiotic Should a Woman Take Daily

There are many different probiotic supplements on the market, and the amount of probiotics women should take daily can vary depending on their individual needs. There are also a lot of probiotics in nature, and needs can vary further on diet. 

Most experts recommend that women consume at least 10-20 billion live probiotics per day for the best results.

Probiotics in Food

Probiotics are found in a variety of food, such as yogurt, sauerkraut, and kimchi. The amount of probiotics depends on how the food was processed and how long it has been stored. As usual, fresh and natural foods are the healthiest.

If you’re looking for food that is high in probiotics, be sure to choose one that is fresh and has been stored properly.

  • Greek Yogurt – 1-2 billion active CFUs per gram. 
  • Sauerkraut – 1,000-100 million CFUs per serving
  • Kimchi – 3.6 billion CFUs per cup
overnight yogurt

CFUs have an unbelievable range as a result of different methods of production and storage. It is impossible to maintain a consistent level of CFUs through diet. That doesn’t mean supplements are essential to health, but they greatly assist in maintaining a balanced probiotic supply.

Many menopausal women take probiotics in order to ease digestive issues, joint pain, hot flashes, and other menopausal symptoms. But with so many different probiotics on the market, it can be hard to know which one is right for you.

Probiotics are an essential component of health. They can be found in food, but are impossible to calculate intake due to variations in food production and storage.

Probiotic Supplements have a similar issue but with much greater accuracy. They optimize nutritional intake, as supplements should. If the common use cases of probiotics appeal to you, they are worth trying.

We compiled the most highly reviewed probiotics on the market to give you the most reliable list possible.

We recommend looking for a product designed for your intended use, whether it be gut health, immune system, joint pain, or weight loss.
