Motown Girl is a personal inspiration for me and you'll find that as you peruse her page, you'll be overwhelmed with the wonderful information she has provided.
By the way, I just conducted a vitamin float test. I took a glass of white vinegar and placed all supplements in. 20 minutes later I was amazed that all GNC products dissolved. But to my dismay, my Puritan Pride Biotin and Vitamin C failed miserably. It's not all bad news because I was running out of both vitamins. That gives me an excuse to go supplement shopping. I'll head back to GNC for those items, since I know that they dissolve. The GNC Nourishair was the first to dissolve...and it's the largest pill!
