I can't reference this method. I learned of it outside of Lyme circles. But it seems to make horse sense.
In my experience, probiotic supplement brands vary a lot as to whether they’re potent or not.
I used Pearls, by Enzymatic Therapy, for years. However, I later repeatedly found their Pearls to be—not potent, by home testing. I spent a lot of money on Pearls over the years, before knowing I had Lyme. When I began taking Lyme antibiotics I continued taking Pearls, plus other brands.
I trust they do make a good product, as I've used some of their other supplements and they were effective (for example, their sleep remedy,) but perhaps shipments sit on a loading dock in the hot Sun or maybe they freeze--killing off the probiotics.
I've tried various brands.
I test each and every probiotic product I buy. I fill a little dish or plastic container with 1/2 cup milk or juice glass with 1/3 cup of milk. I have one container for each product tested. I put a slip of paper under each container, labeling it as the brand. [Paragraph edited for clarity.]
I empty 2 capsules from a product into a container (or cut-open the Pearls) and stir. After 24-48 hours (uncovered) if I see "activity" then I know it's potent.
By activity I mean it should sort of have the consistency of custard. Those products that don't show activity, I bring back to the store for a full refund, and I alert the manager. I test every bottle I buy. After all, it's my health that's at stake!
Sometimes Country Life does well--and it's often on sale at Vitamin Cottage. But sometimes Country Life fails.
This happened when I took two, big Country Life Acidophilus bottles (250 count each,) at the same time, from the refrigerated section at a store: both were on sale, both were the same product and both had the same expiration date. One passed the test very well, the other failed badly.
Again, I wonder about the loading dock idea, especially because some Country Life probiotics must be kept refrigerated. It’s also possible they may have sat on the storeroom floor for a while before being re-refrigerated.
I’ve consistently had good luck with two off-the-shelf brands (off-the-shelf as opposed to absolutely needing refrigeration): Source Naturals and Renew Life. Kyodophilus brand fails for me, repeatedly. Jarrow failed once—the powdered type—and I never tried it again. [Paragraph edited for clarity.]
Evaporation eventually would turn the milk to something sort of custard-like. However, when I've tested multiple brands at the same time, same type of container, same amount of milk, some turn to custard-like and others are still, well, milk! (Though I wouldn't drink them!)
In my experience, a product will pass very well--or fail, outright. I haven’t found any product in between. Sometimes a brand will take a bit longer to become custard-like, than the others.
Dr. Burrascano's Guidelines especially recommend the probiotic type, acidophilus.
The problem with yogurt and kefir is that they are expensive (comparatively) and they don't have nearly enough probiotics, compared to good supplements. Yogurt and kefir can have a high amount of carbs. However, they supply a varied probiotic base in addition to supplements. But then, so can certain probiotic capsules.
I refrigerate all my probiotics, whether purchased from the refrigerated section or off-the-shelf.
I’ve found Whole Foods Market to be very expensive.
I’ve found an independant neighborhood store with good prices and they keep most of their probiotics, even most of their off-the-shelf types,
in their refrigerated section. That says something about their care of probiotics. The idea being, that they'd be potent for a longer period of time.
I check expiration dates.
When I buy probiotics, even off-the-shelf (not refrigerated,) and the weather outside is cool or cold, I drive straight home without the heater on, to get them in my frig. Sunlight streaming through the car windows can raise the temperature quickly--that can affect potency. When the weather is warm or hot I bring an ice pack in a little "cooler," to get the probiotic home safely.
One time, I forgot the ice pack and "cooler." I drove to a drive-in to buy a little glass partly full of ice. I sunk my probiotic bottle into the ice.
I've heard of frozen probiotic supplements--it's deliberate--but how can that be? Anyone seen these?
