I found this thread informative regarding liver tabs:
Review: Desiccated Liver Tablets - IronOnline Weight Training Forum
Edit: The bottom of that thread compares digestion/absorption of four popular brands of liver tabs.
Thanks for this link, it was interesting to see the comparison of how fast the different liver tablet brands dissolve.
I was however a little concerned when I read the following as I just received my big 500 tablet tub of UNI Liver;
"Even more interesting, is that the Universal Uni-Liver product never showed any signs of dissolving. I continued to allow these samples to sit for another 2 hours of course, after 2 hours these would have long vacated your stomach, but in the interest of curiosity I continued on. At the end of the 2 hours time, all the other products had dissolved completely, except the Uni-Liver product remained exactly as you see it above!"
This is bullS%#t I said to myself... So being the big fan of Myth Busters that I am, I decided it was off to the kitchen to find out the truth... this is what I discovered.
To test the UNI Liver tabs I got 2 glasses and filled each with equal amounts of distilled water.
In one glass I put a whole tablet and the other I put a tablet which I broke in half. Oh and by the way they DO sink to the bottom and not float.
Immediately the broken tablet started to dissolve. The unbroken tablet just sat there stairing back at me. Then after about 5 minutes the broken tablet was really starting to make progress which was good to see. However the unbroken tablet was still just sitting there.
On to the 15 minute mark. The broken tablet was more than 50% dissolved and looking good. And as for the unbroken tablet, finally, some progress. The coating had gelled and was starting to "puff" which was promising.
Now at the 25 minute mark brought the biggest surprise. Upon inspection of the 2 samples, I had found that both tablets had almost completely dissolved (well 95%). The last 5% was that tiny unfinished bit in the middle you sometimes get, but after I swished the water around it was soon also dissolved.
So the conclusion is, yes these bad boys dissolve just fine. And I guess if you want to increase the rate of absorption you can always break them in half with your teeth. Good news for UNI Liver, good news for dentists and good news for all of us with 500 tabs sitting in our kitchen;-)
This myth is busted!
