What are the Pros of Nutrition Now PB8?

There are several advantages of this probiotic supplement:

  • It is a  multi-species product.
  • It is marketed for digestion support. Since it contains 8 different species of probiotics which have different and overlapping functions in the body, it might help with digestion depending on a person's needs.
  • It contains NO gluten (wheat), eggs, milk, peanuts, tree nuts or soy.
  • It contains no artificial colors, flavors or sweeteners nor preservatives.
  • Most of the other ingredients (except the inulin) are basically inert.
  • There is a vegetarian option.
  • There is an option with the regular probiotic supplement to have inulin, a carbohydrate prebiotic, to help support the growth of the probiotics in the intestines.

What are the Cons of Nutrition Now PB8?

There are several disadvantages of this probiotic supplement, too:

  • Only the species are given; you don't know which strains are in the product since the information is proprietary.
  • Only the total CFU is given; you don't know how much of each species is present.
  • The total CFU is at the time of manufacture, not at expiration, so you don't know if you are really getting the amount listed on the label.
  • The regular version of this probiotic supplement is made with a gelatin capsule (Beef allergy alert!)
  • The regular version also contains inulin, a carbohydrate prebiotic to support the growth of the microbes, which may pose problems for some people even though it is at an amount less than 1 gram per 2 capsules.
  • As with most probiotic supplements, this one requires refrigeration after it is delivered.
  • No studies with this supplement as a whole supplement have been performed to my knowledge. Note that this is not unusual, however. Very few multi-species probiotic supplements are used in studies. Instead, species and strain that are show to be effective and non-competing are mixed together in most multi-species supplements such as this one.
  • Compared to other multi-species probiotic supplements, this one contains a lower number of total CFU of 7 billion per capsule.

Is PB8 the Right Probiotic Supplement for YOU?

I can help you decide if this probiotic supplement fits your needs. What I will say from personal experience with it that it was one of the first probiotic supplements I took. I like that they offered a gluten-free, dairy-free supplement that said so right on the label when I was trying to navigate the gluten-free world many years ago. Unlike today's circumstances, before the words "gluten-free" were nearly common knowledge and had a meaning, it was very hard to find products I could trust. I trusted this product.

In addition to taking a supplement, I encourage you to explore the world of naturally-fermented whole foods and drinks and probiotic-fortified foods and drinks.

Many thanks to Nancy for suggesting a review of this gluten-free dairy-free probiotic supplement!
