How do I choose the right probiotic?

A reader writes…

“How do you go about selecting the right probiotic?  I’ve heard such conflicting information.  Some say that probiotics are useless, because you’re born with what you have and there’s no way to replenish.  What are your thoughts?”

My first thought is, who on earth is telling people there’s no way to replenish good intestinal bacteria?  Whoever it is, he or she is gravely misinformed on several counts.  First, we’re not actually born with any gut bacteria; we acquire it early on–first during a regular vaginal birth and next during breastfeeding.  (Those who did neither missed out on these opportunities and may not have adequate levels of good bacteria if they didn’t acquire it from other places.)

Next, it’s important to understand that our normal gut flora (beneficial or “good” bacteria) are constantly under attack.  These attacks come from anywhere: stress, processed foods, alcohol, tap water, soil, other animals, medications (especially antibiotics and antacids), other people, and lack of stomach acid, just to scratch the surface.

Why do we need these bacteria in the first place?  They carry out an extensive array of extremely important functions.  They help fight some major disease-causing bacteria; in fact, they help form most of our immune system!  They turn vitamins into their active forms so that our body can use them.  They help you absorb nutrients, including fats, carbohydrates, protein, vitamins, minerals, and others.  There’s even a growing body of evidence that suggests these bacteria may play a role in lowering cholesterol.

So, when we don’t have enough of these bacteria, the above benefits start to evaporate; the immune system becomes weak, other “bad” bacteria (as well as yeasts, fungi, and parasites) can become opportunistic and “install” themselves, you can become seriously deficient in multiple important nutrients, and if the recent studies are correct, your cholesterol may elevate.  Does any of this sound familiar?  It should.  Why?  Because most people are indeed missing much of the good bacteria they need.

So, we turn to probiotic supplements.  I would love to sit down with someone who doesn’t believe probiotics do any good and show them the before-and-after digestive analysis tests of my patients (with names protected, of course), and show them the growth of the colonies of good bacteria between the initial test and the subsequent follow-up.  The numbers of good bacteria do improve.  This is how I know the probiotics are working.

So how does one choose a good probiotic?  There are quite a few choices out there and unfortunately, not all probiotics are created equal.  The supplement industry is largely left to police itself without a lot of regulation, which has both advantages and disadvantages.  The bad news is, there are some that don’t do squat.  The good news is, there are many that are quite effective, and these companies are free to innovate and develop superior products, which many of them have done.

So how do we separate the “men from the boys”, so to speak?  There are two fundamental qualities to look for in a probiotic: a variety of species, and high, potent doses.

At your local health food store, most of the products contain anywhere from 3 to 5 species or so.  This is okay, but it’s not quite enough.  This is because your intestinal tract is essentially a small ecosystem.  There are literally billions, even trillions of different types of bacteria happily co-existing together, each of them occupying space and keeping each other in check, ultimately creating a delicate balance.  Supplementing with a 3-species formula won’t do much.  (Most formulas available only through healthcare professionals typically have much higher quality and potency than those available to the public at health food stores and other places.) The most diverse higher-quality* formulas we have found so far (and thus, the ones we use) contain 12 different species.  While that doesn’t sound like much of an improvement in the grand scheme of things, it seems to work quite well, each additional species having a compound effect.

Next, let’s talk potency.  Potency is measured in colony-forming units, or CFUs.  One CFU, theoretically, goes on to start its own entire colony.  It’s mind-bending to consider how many billions of microorganisms there are in just a teaspoon of probiotic powder.  The storebought brands tend toward lower dosages, somewhere around 5 to 35 billion CFUs.  The highest dose medical grade supplements we found (and incidentally, the ones we use) contain 100 billion CFUs…in a single quarter teaspoon.

And last but not least, as with all supplements, it’s important to avoid supplements that contain (or come from a factory that uses) gluten fillers (wheat germ, wheat flour, wheat proteins, food starches, etc), yeast, soy, egg, milk, corn, shellfish, and MSG, just to name a few.  This is because many (if not most) people actually have immunological hypersensitivites to various common foods, in which the body’s immune system perceives that food as a toxin and launches an attack against it, creating lots of inflammation and chronic, mysterious health problems.  Many storebought supplement companies may be contaminated with these common allergens, but most medical grade supplements specifically state that they are free of all of these substances.

Since our ability to maintain good bacteria balance declines with stress, age, and lifestyle, it’s good to take a high-quality probiotic as part of a maintenance regimen.  This is especially true after finishing a round of antibiotic treatment, such as that for an infection.

*There are other formulas that may contain up to 14 different species, but these are not potent enough to be considered medical food/medical grade supplements, which have the highest quality and potency.

What is Functional Medicine?

The short answer is, Functional Medicine is the future of medicine, if we are to get well and stay well as a society.  It’s the direction in which regular medicine should have gone.  It should be used as the primary method of treatment, especially in cases that are not acute, infectious, catastrophic, life-threatening, or other emergencies.

The long answer is, the definition of Functional Medicine largely depends on who you talk to.

  • The Institute of Functional Medicine, arguably the leader and Gold Standard of the field, describes a science-based, patient-centered form of healthcare that recognizes biochemical individuality and favors active prevention.
  • A talented colleague of mine defines Functional Medicine as a complete lifestyle-modification program that evaluates physiology using extensive diagnostic lab testing and then corrects any imbalances found by applying specific, individually unique combinations of neuro-metabolic therapies.
  • Another talented colleague of mine mentions looking at everything (hormone balance, nutrient metabolism, immune system, and a plethora of other categories) all at the same time, leaving no stone unturned

Functional Medicine really is “all that” – in terms of the explanations given above, as well as being Just That Cool.

When I explain it, Functional Medicine can take on a few different personas that all relate back to the same Big Idea.  Various descriptions are as follows…

  • A highly-advanced version of Clinical Nutrition, taken to another level as practiced by a doctor, that bases its herbal and nutritional plans on comprehensive lab testing
  • A third type of healthcare that is separate from both conventional and alternative medicine branches we’re already familiar with, that utilizes the best of both worlds
  • An emerging medical subspecialty that combines conventional testing and natural therapies
  • A logical, scientific alternative for those looking for natural or holistic healthcare, perfect for those who don’t know where to turn or who to trust.
  • A scientific-yet-holistic of looking at the functions of the body and how they are inter-connected, identifying dysfunctions in key areas using lab tests, and then correcting them with a comprehensive lifestyle modification plan.

That last one is my favorite (couldn’t you tell?)

Functional Medicine really shines with chronic, complex disorders, especially the degenerative and/or mysterious.  I can say it is definitely worth the effort, commitment, and investment!  Most Functional Medicine practitioners know firsthand; many of the best doctors got involved with the field because of their incredible experiences.

We’re a product of the choices we have made every day.  Every day we have another chance to stay on our current path or choose something different.  What are you waiting for? 🙂
