The current recommendation of 400 IU of vitamin D per day may not be enough to prevent vitamin D deficiency. USANA’S supplement has 2000 IU of vitamin D per tablet.

Best vitamin company I have ever delt with
Usana is by far the best vitamins I have ever taken. I have tried several whole food vitamins, capsules and tablets, and have had problems with heartburn or having them get stuck in my esophagus. Usana is more bio-absorbable and I never have that problem. They have the purest vitamins on the market. I have done my research and highly recommend them.

Best vitamins
We are from Utah so we have been aware of USANA for a very long time, started raking them in 1998 while going through the police academy. I know for a fact these vitamins are the real deal. We live abroad and I have them shipped o us here in the Middle East.

You need Vitamin D at the right levels.
A very good way to get your vitamin D. Have it checked next time you get a blood test...I bet you five dollars it is low. It is very important to have the right levels of vitamin D. Look it up!

haven't noticed any difference yet
I've been taking this for a while now and haven't noticed any difference in how I feel, so I have no idea if it is worth it.
