I used to take USANA vitamins but I switched to Herbally Pure vitamin supplemens. I got tired of the nausia with all the pills I was taking. On the herbally pure web site I found a lot of information from the FDA warning about mega doses pills need because of their lack of absotbrion. My family really like the taste and I am so happy that I no longer have to fight with everyone to take their vitamins. I recommend everyone check out the information on the Herbally Pure web site www.HerballyPure.com and try their vitamins and vitamin supplements. I now think Herbally Pure vitamins are the best...
