Comparative Review of the Double X Nutrilite Multivitamins from Amway

Review of the Nutrilite Multivitamins

Amway is one of the biggest nutritional supplement companies in the world. Their line of Nutrilite multivitamins gets a lot of marketing exposure. But how good are the Nutrilite vitamins exactly?

Until recently you haven’t had the opportunity to see how Nutrilite compares to other multivitamin brands on the market. Now you do. Our new comparative study of over 100 brands of multivitamins, such as Nutrilite, USANA, Shaklee, Herbalife, One-A-Day, GNC, Centrum, and Nature Made has revealed some interesting data.

All vitamin brands included in the study were evaluated using the following four criteria: a) composition, b) potency, c) bioavailability, and d) safety. You can learn more about the study methodology here.

Each supplement was assigned a score from 0 to 10 (10 being the highest). Multivitamin supplements with a score exceeding 8.0 are considered to be of the highest quality.

Are Nutrilite multivitamins are among the best on the market?

You’ll probably be alarmed to find that many of the most popular and well-advertised brand-name vitamin supplements scored very low on the scale. Only a small number of supplements met or exceeded the criteria in the study.

The Nutrilite vitamins earned a score 8.3 in our study, ranking 7th overall out of all the one hundred analysed multivitamins.
