U.S. vitamin stats
Since 2004, the top five dietary supplements by retail value sales in U.S. dollars have remained remarkably constant; calcium supplements and minerals supplements remained No. 1 and No. 2, respectively. Fish oils, glucosamine and probiotic supplements fluctuated in their top five rankings throughout the 2004–2009 time period. Co-enzyme Q10, eye-health supplements, garlic, ginkgo biloba, ginseng, protein powder and royal jelly all appeared in the remainder of the top 10 during the same time period. Global sales of vitamins are also unvarying during the 2004–2009 time period.
Multivitamins are the No. 1 type of vitamin sold, with sales usually four times that of the No. 2 vitamin—vitamin B. Vitamin C is in third place, with triple the sales of fourth place vitamin E. In recent years, vitamins A and K have alternated for fifth place, while vitamin D lags in seventh place. However, vitamin D had the highest growth rate in 2009 at 38.7%. Vitamins are flexible, popular products, valued as supplements and ingredients.
