With supplements dominating wellness trends across social media, it’s easy to assume that popular, over-the-counter options are effective—or even necessary—for better health. But according to medical experts, not everything on the shelf lives up to the hype. In fact, some widely used supplements may do very little for your body, while potentially causing unwanted side effects or simply draining your wallet.
Doctors are now urging consumers to take a closer look at what they’re buying, especially when it comes to heavily marketed products that promise quick fixes. From weight loss pills packed with stimulants to everyday multivitamins that may not absorb well, certain trending supplements are being called out for offering more marketing than real results. Here are two that experts say aren’t worth the money—and why you may want to think twice before adding them to your routine.

1. Hydroxycut and OTC Weight Loss Supplements
Pharmacist Jamie dives right into the reasons why hydroxycut along with OTC weight loss supplements don’t work: “They’re basically a lot of caffeine, some B vitamins, and apple cider vinegar.”
While there is some evidence that caffeine can “help with appetite suppression,” she notes that these supplements are simply loaded with caffeine. This will cause jittery feelings and less appetite, but it’s nothing more than drinking coffee, she says.
“There’s no evidence that these actually help with weight loss,” Jamie says. As for the other ingredients, she reveals that apple cider vinegar has “some very mild research that it can help with weight loss,” and you might as well just purchase a bottle of apple cider vinegar instead.
“Don’t waste a ton of money on this fancy product with a brand name,” because “there are no real studies to back up that [hydroxycut and over-the-counter weight loss supplements] really does much of anything.”

2. Multivitamins
Dr. Austin Lake recently shared insightful warnings about this very issue on TikTok, cautioning against seemingly ubiquitous multivitamins. Although many multivitamin bottles appear to be a great way to get essential nutrients in one simple package, he bluntly states that "they just aren't going to be all that helpful to you" and "can potentially be a big waste of money" due to their low bioavailability and artificial additives.
Dr. Lake encourages a shift toward obtaining essential nutrients from a well-rounded diet rather than relying on these widely marketed multivitamins.
The bottom line
Not all supplements are created equal, and just because something is popular doesn’t mean it’s effective. Experts stress that many trending options—like over-the-counter weight loss pills and multivitamins—may offer minimal benefits at best and unwanted side effects at worst.
Instead of relying on quick fixes, focusing on a balanced diet, proper hydration, and targeted supplementation (when truly needed) is a more reliable and cost-effective way to support your health.
