Mixes easily in juice; wait 15 min
I was tired of taking 8 large 500 mg capsules per day to get 4,000 mg, split between morning and night. So I tried this product. To me, it has a slightly "milky" taste. But I have been stirring a teaspoon (2,200 mg) into 4 oz of juice, letting it sit for 15-30 minutes to completely dissolve, and then chugging it down while holding my breath. Twice a day. It mostly tastes like juice, and is very easy to do!

Best value for lysine
I give this to my cats and mix it in their wet food. This product is the best value for lysine and much easier than grinding tablets up for every meal. It is grainy though and does not dissolve easily in liquid. Sometimes it clumps together when wet instead of dissolving. Depending on the texture of the food I am mixing it in, sometimes I still have to grind it in a mortar and pestle so it will blend in. But being grainy it is less prone to turning into a dust cloud than grinding tablets.
