Comparing Nature’s Bounty to Align probiotics

Are you interested in trying out probiotics but not sure where to start? Likely you’ve heard about their benefits, whether through your closest friends or even your family doctor. In a nutshell, probiotics are essential to good gut health as they help your digestive tract stay in balance. 

And since they’re easy to incorporate into your diet on a regular basis, there’s no reason why you shouldn’t test them out, especially if you’ve had gut problems in the past. Probiotics can be particularly beneficial to those with gastrointestinal issues, such as food intolerances, IBS or other sensitivities. And while there are a number of probiotics on the market, selecting one to try can be overwhelming. To keep things simple, it’s best to go for a reputable brand like Nature’s Bounty or Align. Here’s everything you need to know to make the best purchase.  

Probiotic terminology

While you can incorporate probiotics into your diet using certain foods, such as kefir and sauerkraut, taking a daily supplement will guarantee that you’re getting the exact dose your body needs each day.

When deciding on a probiotic, it may be confusing to see packaging with terminology that is foreign to non-probiotic users. When you see CFU it refers to “colony-forming units.” Most standard probiotics for adults have at least 1 billion CFU, which are the live organisms that will help your digestive system when consumed. Additionally, many probiotics include the following bacterial cultures (which are the most commonly researched):

  • Lactobacillus (helps unhealthy bacteria from growing in the intestines)
  • Bifidobacterium (helps support gut microbiota and improve the intestinal environment)
  • Saccharomyces boudlardi (helps treat and prevent diarrhea) 
  • Acidophilus (helps break down sugars, such as lactose, into lactic acid). 

Now that you know what to expect, here’s a side-by-side comparison of Nature’s Bounty vs. Align probiotics:

Nature’s Bounty

Nature’s Bounty is a nutrition-focused company that has been around for decades. They are a health-conscious brand, providing a wide range of vitamins and supplements for a variety of purposes.

Their probiotics help promote healthy digestion and nutrient absorption. 

Nature’s Bounty pros

Nature’s Bounty has several probiotic options, making it a great choice for those seeking flexibility and variety. Some of their probiotics are tailored toward heartburn and IBS issues, while others are more generic. They also have a gummy option for anyone who dislikes swallowing pills.

Nature’s Bounty also has a high CPU count and offers larger bottles of product for an average-to-above cost. 

Nature’s Bounty cons

While the pricing is fairly standard and overall reviews on quality are good for Nature’s Bounty (if not better than many sother options on the market) the packaging can be a bit confusing to new users. Some bottles read: “2 billion CPU, 10 strands and 1 million organisms,” which, unless you’ve spent a lot of time researching probiotics, is not very user-friendly. Therefore, their terminology and dose information may not resonate with every consumer and may lead to confusion and frustration. 

Additionally, as with any live bacteria, consuming the improper amount could lead to bacterial infections, stomach upset or issues such as candida. Always check with your doctor if you are having issues or are unsure about a product.

Align is a popular brand of probiotics and advertises as the number one doctor-recommended probiotic. They profess they are rooted in nature and backed by science.

Align offers many intake options, including gummies, chewables and regular and extra-strength capsules. They are also vegetarian and gluten-free and aim to promote and restore optimal gut health, specifically to those suffering from digestive upset and IBS.

Align pros

Align’s products are generally safe for those with dietary restrictions, including soy and gluten sensitivities, as well as vegetarians. Their packaging is very user-friendly and they are not costly, which is crucial if you plan on taking these supplements daily for an extended period of time or are on a limited budget. 

Align cons

Although Align’s packaging is arguably very simple (especially when compared to Nature’s Bounty), the overly-simplified language could lead consumers to disregard the need to research their supplement or take the supplement less seriously.

Probiotics should never be consumed if you are pregnant, nursing, on medication or concerned about health issues. You want to make sure you’re aware of every ingredient before taking one, so thoroughly reading (and understanding) each packaging is a must.

Should I choose Nature’s Bounty or Align probiotics?

While both brands offer quality products and have good reputations, in terms of affordability and providing the best value for your money, Align offers the most user-friendly packaging and their product has more options for alternative supplements.
