I used to love this product, and especially with the amino acids, I noticed a difference in my health. However, the "new and improved" version with the B vitamins incorporated in the powder is a big disappointment. It leaves a gritty feeling in my throat, tastes bad and leaves an aftertaste. Mixing it and letting it sit in the glass for 15 minutes seems to help dissolve the extra vitamins and relieve some of the grittiness. However, after using and liking this product for a year, I think I'll find a different multivitamin, rather than put up with the new formula.
