 High Quality, Pure TyrosineMar 18, 2012
By Real-Life Test
This is to counterbalance the review slamming the product because it refuses to dissolve in their morning vitamin drink as they expected it would. However long they stir or patiently wait, they complain it "NEVER dissolves, even after hours in liquid!" and insinuate there's something wrong with it.
To be clear, L-tyrosine is nearly insoluble in water, juice or anything else that's mostly water. It's a physical characteristic like a melting point that can't be changed. If anything, its insolubility in any liquid humans are likely to drink, speaks to its purity! It's not supposed to dissolve.
I just finished a bottle of this very brand of L-Tyrosine and was very pleased with the product. It works out much cheaper than the capsules, which are just as insoluble, btw.
There might be an answer to the reviewers dilemma and that's to use N-Acetyl-L-Tyrosine, which might well be far more soluble in water as are so many otherwise water-insoluble substances when they are acetylated -- a process that frequently also makes them cross the blood-brain barrier more easily. Maybe that's why the standard dose for N-A-Tyrosine is 300 mgs as opposed to 500 mgs for straight Tyrosine.
Anyway, L-Tyrosine isn't supposed to dissolve easily, but it's cheaper, this brand is good and you can -- as the reviewer points out -- suspend it in different things, including water. Just get it swirling around and swallow!

 Not what I expectedMay 25, 2011
By Evep
I thought it would be easier to put the "powder" into my morning vitamin drink I make. This product is granules that NEVER dissolve ,even after hours in liquid! Not only that,they sink to the bottom of my glass and stay there, no amount of stirring helps. Now putting on applesauce to ingest. Staying with my old capsules in the future.
