Nature’s Bounty Probiotic-10 Ingredients

Nature's Bounty Probiotic-10 Ingredients

Lactobacillus brevis (L. brevis) is available in approximately 16 different strains, and commonly found in some milk products and plants as they decompose.

As a gram-positive, lactic acid producing bacteria, L. brevis can be found in many foods that are rich in probiotics, including yogurt, sauerkraut, sourdough bread, and a fermented Japanese vegetable called suguki. The probiotic L. brevis has not been the subject of many scientific studies, but it may help treat and prevent diarrhea in children and improve gastrointestinal health when consumed as part of a probiotic supplement.

Lactobacillus casei (L. casei) is added to probiotic supplements to help regulate your digestive system. Health benefits include the prevention or treatment of diarrhea, constipation, IBS, lactose intolerance, and Crohn’s disease. In addition to being found in probiotic supplements, L. casei is often found in probiotic drinks, probiotic yogurts, and some types of fermented milk and cheese.

Another of the main ingredients in Nature’s Bounty Probiotic-10 is Lactobacillus plantarum. L. plantarum can be isolated from a variety of fermented foods around the world, including fresh-water fish, soybeans, and pork. The benefits to human health can include treatment and prevention of inflammatory bowel disease (IBD), antibiotic-associated diarrhoea, and irritable bowel syndrome (IBS).

What sizes are available?

With a serving size of 2 capsules, each box supports you for up to 1 month of daily use. You can also buy multiple boxes at the same time for a small discount.

However, at the time of writing this review, the best value for money actually comes from the single box of 60 capsules. Each daily dose was priced at $0.40, compared to $0.47 if you bought the 2-box multipack. That’s why 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 Nature’s Bounty Probiotic-10.

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.).

Review Overview

Overall Review Rating

4.5 / 5

So, is the Nature's Bounty Probiotic 10 supplement worth buying?

Unless they only contain B. coagulans, the vast majority of multi-strain probiotic supplements contain many different bifidobacteria strains. Probiotic 10 contains just 1, in the form of B. lactis.

The 9 other probiotic strains include 2 different types of L. paracasei (DSM 13434 and Lpc-37) and L. plantarum (Lp299v and DSM 15312). This means that, based on current scientific studies, it's going to be less effective at relieving IBS symptoms such as stomach pain, bloating, and difficulty having a bowel movement.

However, having such a strong focus on lactobacillus probiotic strains means Probiotic 10 is particularly effective at speeding children's recovery from rotaviral diarrhea. It's also going to be more effective at preventing diarrhea caused by antibiotics and cancer treatment (chemotherapy).

Overall, Nature's Bounty Probiotic 10 contains enough live cultures and probiotic strains to improve digestive health. Just be aware that you may not experience the same full range of health benefits that you could with a probiotic that combines multiple lactobacillus and bifidobacteria strains, such as Garden of Life Primal Defense Ultra (5 bifidobacteria strains, 7 lactobacillus strains, 15 billion CFU).
