I love BUICED vitamins so much that I bought a case each of B2 and D3.. I would have bought a case of Zinc, but were running out of stock. I highly recommend BUICED products. My body is thanking me profusely. Since taking Buiced vitamins (Multivitamins, B12, Zinc and D3), I have not had a cold or a sinus infection in over a year! That is huge for me because I typically get at least two sinus infections a year. BUICED FOR LIFE!
