For some time I have wanted to show evidence to the public that Vitamin Inspector is a good tool for comparing multi-vitamins nutritionally. An opportunity to do this arose with USANA producing a new formula for their multi vitamin and mineral product. (USANA are a manufacturer of high potency multi vitamins and other health related products.)

USANA scientists wrote an article on the differences – “What changed in the Essentials/CellSentials Formula” . Unfortunately, they have removed the article from their website since this test was made and review written. Nevertheless it is interesting to see what the article said about the new formula and at the same time look at the differences that Vitamin Inspector shows when it does a software comparison on the labels. Will Vitamin Inspector agree with what the USANA scientists have said? Will it find other changes?

The formula for Essentials and CellSentials changes depending on where it is sold in the world. The USANA article concentrates mostly on the differences in the United States market. This review will also concentrate on the US market.

So, how does the new USANA multivitamin, CellSentials stack up against the older Essentials? Vitamin Inspector is exactly the right tool to help us. Let’s dive in and find out…

Summary of differences

The comparison by Vitamin Inspector backs ups what USANA says about the changes in their product.
It also shows some other changes that are not mentioned by USANA.
Other removals seen by Vitamin Inspector:

  • Pomegranate extract
  • Cinnamon extract
  • Bilberry extract

Other additions seen by Vitamin Inspector:

  • Silicon is showing as an addition although it was part of “Other ingredients” in Essentials

Note: Vitamin Inspector compared the USA product and the USANA review
was about their global product.


This review supports all the statements made by USANA and shows that Vitamin Inspector is indeed a good tool to find the differences between complex mutli-vitamin products.

  1. There could also be other changes which Vitamin Inspector cannot assess, for instance, in the composition of extracts. Changes to inactive ingredients have not been counted.
  2. Vitamin Inspector compares the ingredients stated on the label. It does not test multi-vitamins or other supplements.
  3. Nutritional Comparison, compares only the active ingredients line by line, not the ‘other’ or ‘inactive’ ingredients.
