Naturo Sciences Probiotics 15 Ingredients

Naturo Sciences Probiotics 15 Ingredients

Bifidobacterium bifidum (B. bifidum) is one of the most common strains of probiotic bacteria found in the human body, mostly inhabiting the mouth and gastrointestinal tract. As one of the lactic acid bacteria, B. bifidum can be found in a range of fermented foods, including some yogurts and cheeses. Health benefits include prevention and treatment of irritable bowel syndrome (IBS), lung infections, constipation, and certain types of diarrhea. Some studies have also found B. bifidum to be beneficial to the immune system.

Bifidobacterium longum (B. longum) is a type of “good” bacteria that’s found naturally in the human gastrointestinal tract, and one of 32 types of bifidobacterium. One study on a specific type of B. longum (strain 1714), found that people who supplemented with it improved their memory function, reported fewer cases of mild anxiety, and had lower levels of the stress hormone cortisol in the morning. Further research shows that B. longum has a powerful effect on boosting your immune system. The lactic acid produced by the bacteria also increases the acidity of the digestive tract, which helps restrict the growth of harmful bacteria.

Lactobacillus gasseri (L. gasseri) is a type of probiotic that’s found naturally in breast milk, and is naturally present in the human digestive system along with other Lactobacillus species (rhamnosus, acidophillus, etc.). Initial, small-scale studies have shown certain strains of L. gasseri (BNR17) to be beneficial to weight loss, reducing body weight and hip circumference for overweight adults. Further research, published in the British Journal of Nutrition, also found the SBT2055 strain of L. gasseri helped to reduce abdominal fat over a 12 week period.

What sizes are available?

With a serving size of 1 capsule, each box provides you with either 60 servings – the equivalent to a 1 month supply. You can also buy multi-packs which offer a discount, and a starter set that includes the Naturo Sciences Colon Care product.

At the time of writing this review, the best value for money comes from the multi-packs, where you buy either a two pack (120 servings) or three pack (180 servings). Each serving was priced at $0.36, compared to $0.42 if you buy just a single box.

We always recommend calculating the average cost per serving, across all sizes, before making a final buying decision.

Save money with Amazon

If you’re looking to save money on your monthly supplement order, you might want to consider the Amazon Subscribe & Save program.

Subscribe & Save allows you to unlock savings of up to 15% on a wide range of sports nutrition products, including Naturo Sciences Probiotics 15 (selected sizes only).

You can save 5% with a subscription to 1 product, or save the full 15% by subscribing to 5 products, provided they’re all delivered to the same address. The delivery schedule can be set from monthly, up to once every 6 months.

Although 5 products might sound a lot, if you already supplement with a protein powder, multivitamin, creatine, BCAA, and glutamine, the savings can soon add up. But it’s best to order before you run out of your current supplements, because Amazon set the day of the month each order is sent (same day each month e.g. 14th.).

Who are Naturo Sciences?

Naturo Sciences, LLC. is a health supplement company registered in Indiana, United States. Although their website has an entire page dedicated to their history and focus on quality ingredients, there’s no information relating to ingredient sourcing or testing.

With some of the larger supplement companies we review, you’ll find a wealth of information detailing every aspect of production. Nordic Naturals, for instance, dedicates a section of its website to explaining their research and testing process. For their fish oils, this also includes their approach to Corporate Social Responsibility (CSR) and support for Friend of the Sea (marine conservation non-profit).

Unfortunately there’s no sign of this with Naturo Sciences, who simply state that they use the finest ingredients and thorough nutritional research. While this may be true, at the time of writing this review it was impossible for us to independently verify these claims.

Review Overview

Overall Review Rating

4.5 / 5

So, is Naturo Sciences Probiotics 15 worth buying?

The composition of probiotic strains and level of CFU is very similar to Nutrition Now PB8 (14 billion CFU, 8 strains). Probiotics 15 contains L. gasseri instead of L. casei, and doesn't contain L. rhamnosus or L. salivarius.

B. bifidum has similar health benefits to L. casei (treatment of IBS and certain types of diarrhea), while L. gasseri has been shown to provide weight loss benefits in some small-scale studies.

However, if you're not concerned with the potential weight-loss benefits of L. gasseri, you might prefer Nutrition Now PB8. The fact that it contains L. rhamnosus means it's better suited to the prevention and treatment of antibiotic-associated diarrhea (ADD) in children and adults.

Overall, Probiotics 15 is a high quality probiotic supplement for that helps to maintain a healthy digestive system and strong immune system. It's also one of the top probiotic supplements on Amazon, with hundreds of highly rated reviews, praising its ability to restore normal bowel movements, improve digestive issues, and reduce symptoms of IBS.
