Best selling vs. highest quality

Protein Powder

” You get what you pay for.”

As consumers, we want to believe that spending more on a product ensures us a higher quality result. But a new set of studies indicates that this heuristic could have serious flaws, especially in the supplement industry.

There have been a rash of negative articles about supplement quality over the past month, and for good reason. Meanwhile, the FDA performs no pre-market regulation of dietary supplements, so manufacturers are left responsible for quality control.

LabDoor recently performed an analysis of 50 best-selling protein supplements and attempted to determine whether there was any correlation between quality and price in this industry.

So, how did the supplement industry fare in this LabDoor analysis? Not well. Check out the following two lists of protein supplements, alternatively ranked by sales and quality:

Best Selling Highest Quality
1. Cytosport Muscle Milk 1. MET-Rx Protein Plus
2. Optimum Gold Standard 2. Nature’s Best Zero Carb Isopure
3. MuscleTech Phase8 3. Shakeology
4. MusclePharm Combat Powder 4. MuscleTech NITRO-TECH
5. Cellucor COR-Performance Whey 5. NOW Foods Whey Protein Isolate
6. BSN Syntha-6 6. Jay Robb’s Whey Protein
7. Dymatize Elite 100% Whey Protein 7. CytoSport Monster Milk
8. Dymatize ISO-100 8. Optimum Pro Complex
9. Optimum Serious Mass 9. MusclePharm MuscleGel Shot
10. Optimum Platinum Hydrowhey 10. Nature’s Best Zero Carb Isopure Drink

Out of the fifty products selected for this analysis, no products made it onto both top-10 lists. Would the industry have done any better if the products on the two lists were chosen randomly?

LabDoor “identified a positive correlation between a product’s price per serving and its protein content per serving (n=50, R2=0.3441), but found no statistically-significant correlation between a product’s price per serving and its quality rating (n=50, R2=0.0017).

So, the next time you’re in a GNC, take LabDoor with you. Don’t leave your safety up to chance.
