Mark Cuban’s Take on “Health Gimmicks”

There seems to be a rapidly growing number of health-focused products out there. It can get confusing to know which ones will work and which are just get-rich-quick scams. Mark Cuban, a business guru and judge on the hit show Shark Tank, expressed his frustration with healthcare products promising results not backed by sound science, particularly when it comes to vitamins and supplements.

The “Promise” of Supplements

In an article in the New York Post, Cuban said, “Everyone wants to feel better, to be healthy, to be fit, to look good, and the promise of supplements plays right into that dream.” While critical of supplements in general, he is especially skeptical on the show. “It really bothers me when we have a product that could take advantage of the [people] who trust us.”

Things like “shaky scientific claims” and pseudoscience get Cuban so fired up, he’ll argue with guests, other judges, and even doctors if their products are not substantiated with real clinical results. “I’m all for people getting healthier, but more often than not, there are no studies that connect directly to the product being offered. And when there are studies, they are typically for something that doesn’t replicate how customers would consume the product.”

Frustration Based In ExperienceThough vitamins can be helpful, some products sold in retail stores may not contain exactly what's on the label.

While Cuban’s arguments on the show can appear hostile, it’s all stemming from emerging research finding that many supplements on the shelf are not all they claim to be. In 2015, DNA tests were conducted on several popular supplements and found that in 4 out of 5 cases, the pills contained nothing more than fillers like rice, asparagus, wheat, and even houseplants!

Similarly, in 2014, researchers tested a few popular AREDS 2 eye vitamins found in retail stores. The results showed that ingredients listed on the labels were not in the amounts listed or downright missing. One of the vitamins tested claimed to be an AREDS 2 formulation but was missing 4 of the 6 necessary ingredients! “It’s shocking how even the best-selling brand names not only have variability in their batches but often significantly vary in mix from their labels,” Cuban says.

One thought on “Mark Cuban’s Take on “Health Gimmicks”

  1. I have been on eye promise restore for 1 1/2 years. My Doctor said that my numbers wouldnt get any better, but taking the supplement they wouldnt get worse. My numbers were.10 at the start. 6 months later I went for a recheck and the numbers were .014. Both of us were surprised. Was hoping that they hadnt dropped lower. My last 6 month check up, the numbers were .34. I had included Vitamin B6 and Vitamin C into my regime these past six months. I firmly believe in this product and recommend it to everyone
