Before you spend money on that “Shark-approved” miracle invention, weight loss product, or keto diet pill, are you sure it’s really been through the Tank? Really sure? Scammers are using fake Shark Tank celebrity testimonials and endorsements — complete with doctored photos and videos — to generate buzz and profits. Before you click and buy, follow this advice and check it out.

Here’s what to do if you’re wondering whether something is Shark-approved:

  • Approach celebrity testimonials with caution. Look for product reviews on your own. Search the product online and put words like “scam” or “problems” or “complaints” to see what others are saying about the products.
  • Go directly to the source. Don’t click on a link or ad. Instead, check out a full list of all businesses that have been on the show at
  • Remember: the government doesn’t review or evaluate supplements for safety or effectiveness before they’re put on the market. Your health care professional is the most important person to ask whether a supplement is safe for you. Even a natural supplement can be risky depending on your health and the medicine you take.
