In several of our formulas, including the top-rated, best-selling Jigsaw Magnesium w/SRT®, we use a proprietary Sustained Release Technology (w/SRT®) tablet.
Over the years, we've had customers put our SRT tablets into a glass of water, and then watch them sit there and pretty much do nothing.
They ask us, "My pills don't dissolve in water, does this mean they're ineffective?"
They assume because the tablet doesn't break down in a glass of water, then it's not breaking down in their GI tract, and therefore, it's not being absorbed.
And on the surface, that's a very logical assumption.
Jigsaw Magnesium w/SRT was not designed to break down in water, nor was it designed to break down quickly.
In fact, we purposefully decelerated the release of nutrients.
Well, in the case of Jigsaw Magnesium w/SRT, magnesium has "hydrophilic" properties. That's just a a fancy word for "attracts water", sort of like a magnet.
So when you ingest, or "dump", magnesium into your gastrointestinal (GI) tract, the magnesium draws water into your GI tract. But the GI tract can only hold on to so much water for so long.
And for most, this leads to a serious laxative effect. (Btw, this is how products like Milk of Magnesia® work.)
Jigsaw's sustained release tablets are purposefully designed to break-down slowly so that your body can absorb the magnesium over an extended period of time, rather than trying to deal with a "flood" of magnesium in a short period of time.
This may seem counter-intuitive, but we did it this way so our customers could take a large dose of magnesium once (or twice) per a day. And for most, it helps keep them regular without feeling like a harsh laxative.
Our contract lab utilizes dissolution testing to ensure that the tablet breaks down over an 8 hour period. And the dissolution test has three major difference from a glass of water:
One Final Note...
There are many smart, well-to-do health professionals that encourage consumers to stay away from tablets entirely, generally on the basis that tablets don't absorb as well as capsules, liquids, or powders.
And for the most part, we totally agree with that sentiment...
...except, for instance, when it makes sense to decelerate and sustain the release of the nutrient so the body can absorb over time as it travels through the GI tract. And that's what we do with Magnesium, B Vitamins, Vitamin C, 5-HTP, and Melatonin. (Here's a short animated video that explains why Jigsaw uses sustained release technology.)
If your doctor has told you this, we respectfully ask that you pass this article along to them so they can get a fresh perspective on why sometimes, tablets are preferred.
PS - If you happen to see an undigested SRT tablet in your stool (which does happen to some customers from time to time) this is likely a sign that your GI tract is running low on probiotics -- these are the good "bugs" that make up the healthy flora in our GI tract and help break down food and supplements. If this happens to you, we'd encourage you to talk with your healthcare professional about adding Probiotics and/or Digestive Enzymes to your regimen.
